    Full Text Available Située à proximité de Paris, Aubervilliers, au cours du XIXe siècle, connaît une forte croissance de sa population et une transformation de son tissu social avec l’arrivée de migrants et l’orientation des activités économiques vers l’industrie au détriment de l’agriculture traditionnelle. Dans le cadre d’une réfl exion générale concernant la place du parrainage dans la construction des liens sociaux et particulièrement de la sociabilité communautaire à l’échelle locale, la distribution spatiale des parrains et marraines des enfants baptisés dans l’unique église paroissiale de la localité a été analysée sur trois siècles, afi n de montrer la fi n progressive du parrainage entre voisins appartenant à une même communauté, la paroisse, entre XVIIIe siècle et XIXe siècle, et l’élargissement du bassin de recrutement des parents spirituels, celui-ci témoignant du recul de l’esprit communautaire ancien. Au XIXe siècle, quand les choix dans la parenté n’amènent pas à aller quérir des parrains loin d’Aubervilliers, d’autres types de parrains voisins apparaissent: les gens du quartier, voire les voisins d’immeuble, prennent alors une place importante, notamment dans le quartier ouvrier peuplé de migrants de Quatre Chemins-Champ Blanc, au sud de la commune. Il ressort ainsi de l’analyse détaillée des baptêmes de 1881 que l’espace de la banlieue était loin d’être uniforme. Par beaucoup d’aspects dont le parrainage, Aubervilliers était bien une «périphérie» de Paris (cf. la proportion de parrains et marraines vivant dans la capitale, mais en son sein plusieurs quartiers, où des logiques de choix diff érentes étaient mises en oeuvre au moment des baptêmes, coexistaient.

    Full Text Available L’apparition des premiers livres de cuisine au Mexique - publiés par des maisons d’édition françaises spécialisées en ouvrages en espagnol - marque le début de l’histoire de la cuisine mexicaine. Cet événement s’inscrit par ailleurs dans une histoire plus large : celle de la construction de l’État-nation, entre nationalisme et cosmopolitisme. L’article s’intéresse aux idéaux de nation et de cuisine cohabitant dans deux des livres de recettes francisés du XIXe siècle au Mexique : l’Arte novísimo de cocina et le Nuevo cocinero americano/mexicano en forma de diccionario.French-fashioned Mexican recipe books in the 19th century. Globalization and construction of a national culinary modelThe first Mexican recipe books were published in the early 1830’s by French publishing houses specialized in Spanish written books. This article deals with the different nationalistic and cuisine models in two French-fashioned Mexican recipe books -the Arte novísimo de cocina and the Nuevo cocinero americano/mexicano en forma de diccionario- and their relationship with the nation-building context in nineteenth century Mexico.

    Full Text Available La construction sociale des orthodoxes de Beyrouth, au début du xixe siècle, s’effectue autant dans le cadre de la communauté qu’à travers un réseau de relations et d’obligations économiques et sociales extérieures.

  6. La bande dessinée en Belgique francophone au XIXe siècle

    Directory of Open Access Journals (Sweden)

    Frédéric Paques

    2012-02-01

    Full Text Available La Belgique a une grande tradition de production de bandes dessinées et reconnaît le neuvième art comme l’un des fleurons de sa culture nationale. Pourtant, la plupart des livres traitant d’histoire de la bande dessinée dans ce pays ignorent totalement l’époque pré-hergéenne. Et pour cause, la production de bande dessinée en Belgique est à la fois relativement peu nombreuse et, pour une bonne part, tributaire de l’influence étrangère. De plus, les bandes dessinées présentant du texte sous l’image ont longtemps été complètement ignorées par les historiens du sujet. Cet article se propose de rechercher les diverses apparitions de séquences d’images au XIXe siècle et de les contextualiser. Nombre des exemples que nous avons trouvés constituent des expériences sans lendemain, produites dans des contextes différents de celui qui donnera naissance à la bande dessinée belge de l’âge d’or : trouver une filiation directe n’était pas notre but premier. Pourtant, du Déluge à Bruxelles créé en 1843 par Richard de Querelles aux images populaires du Liégeois Georges Ista, juste avant la première guerre mondiale, la bande dessinée belge au XIXe siècle se révèle au final d’une richesse et d’un intérêt insoupçonnés jusqu’ici.Belgium has a great tradition of production of comic strips and recognizes the 9th art as one of the jewels of its national culture. Nevertheless, most of the books dealing with history of the comic strip in this country ignore totally the time before Hergé. For a good reasons : the production of comic strip in Belgium is relatively rare and, largely, dependent on the foreign influence. Furthermore, comic strips presenting text under the image were completely ignored for a long time by the historians of the subject. What we suggested making in our work, is looking for the diverse appearances of sequences of images through time and contextualise them. Number of the examples

    2004-03-01

    Full Text Available Le XIXe siècle est le siècle de la « fièvre thermale » en France. Pour permettre cet extraordinaire développement, l’argent est nécessaire. La station thermale apparaît comme un eldorado où la fortune est à portée de la main. Cette fortune n’est pourtant pas si facile à obtenir, la gestion thermale est ingrate, et les centaines de villes d’eaux françaises ne peuvent pas toutes obtenir un succès comparable à celui de Vichy ou d’Aix-les-Bains. Le thermalisme français est diversité, diversité dans les réussites, diversité dans les types de gestion (de la gestion étatique à la gestion privée, diversité dans sa fréquentation, diversité dans ses périodes de développement, diversité dans les moyens de son financement. Etudier l’importance ou au contraire la rareté des réseaux d’investissement dans le thermalisme permet de lever une partie du voile de l’histoire encore bien mystérieuse des villes d’eaux françaises.

  8. Quand l'indéfini négatif pouvait s'employer au pluriel. Les emplois de « aucun(es » au XIXe siècle

    Directory of Open Access Journals (Sweden)

    Denizot Camille

    2014-07-01

    Full Text Available L’étude porte sur l’existence paradoxale d’indéfinis négatifs au pluriel dans la langue du XIXe siècle. La situation du XIXe siècle atteste en effet d’un état de langue intermédiaire entre deux systèmes stables : celui de l’ancien français où aucun est un indéfini positif qui peut s’employer au singulier comme au pluriel, et celle du français contemporain où aucun est un indéfini négatif qui ne s’emploie plus qu’au singulier, tandis que le sens positif se survit seulement dans la forme de pronom pluriel d’aucuns. Au XIXe siècle, aucun est donc devenu globalement négatif tout en acceptant encore des emplois du pluriel. Si l’explication diachronique motive ce paradoxe, encore faut-il comprendre comment s’interprètent et se justifient ces pluriels pour des indéfinis de sens négatif, dans la synchronie du XIXe siècle. À travers cette étude de cas nous nous interrogeons sur la cohérence synchronique d’un système instable, au croisement de plusieurs évolutions diachroniques. Dans cette optique, nous tentons de comprendre comment se justifie le pluriel des indéfinis négatifs, et comment ces indéfinis pluriels, dont on conçoit mieux la justification a priori pour un sens positif, peuvent développer dans le même état de langue un sens positif et un sens négatif. Nous montrons ainsi que l’emploi du pluriel dans un grammème négatif ne se limite pas au phénomène de l’accord, même s’il tend à s’y cantonner progressivement, et que la coexistence d’un sens négatif et d’un sens positif pour le même grammème n’est pas source d’ambiguïté en synchronie : l’emploi vivant, négatif, vient concurrencer l’emploi positif, résiduel, uniquement dans les contextes à polarité positive et l’interprétation négative y est construite pragmatiquement.

    Full Text Available Du XVIIe au XIXe siècle, la représentation cartographique de l’île de la Réunion a été souvent indigente avant que ne se manifestent, avec retard, les progrès techniques apportés par le calcul précis de la longitude et la triangulation. Deux siècles seront nécessaires pour passer d’une expression cartographique imaginaire puis erronée à une représentation correcte reprise par la cartographie moderne.

    International Nuclear Information System (INIS)

    Faulot, J.P.; Pastorini, S.

    1993-10-01

    The SICLE software includes a simplified modelization for pumps located on fluid circuits. This modelization is based on operating specifications (four quadrants), on energy conservation equation and on the second law of dynamics. The pump is considered like a punctual component without storage of mass or energy. In that case, it is the simplest punctual component of the different elementary modules of SICLE. Nevertheless, for a user, it represents one of the most complex component to model because of the many geometrical (driving or not by motor, turbine with or without coupling, etc...) and functional possibilities (operating in the four quadrants, motor specifications, turbines specifications, internal loss values, etc...).

    Full Text Available Depuis le concile Vatican II, la volonté de l’Église catholique de tendre vers une plus grande simplicité pour réduire la distance, tant physique que psychologique, entre ses ministres et l’ensemble des fidèles a contribué à abandonner certains fastes de la liturgie. Aujourd’hui, l’étude des ornements liturgiques rend compte de leur place au cours des rites et de l’attention portée à leur réalisation. Le XIXe siècle est souvent considéré comme l’âge d’or de leur confection. Une recherche menée dans le diocèse de Moulins a permis de mettre au jour la richesse et la diversité des collections de cette époque, ainsi que le renouvellement de la portée symbolique et politique dont ils ont fait l’objet.Since the II Vatican Council, the wish of the Catholic Church for simplification in order to reduce the distance, both physically and psychologically, between their Ministers and all the believers, contributed to abandon some complex aspects of the liturgy.

    Introduit en 1816 par le Dr Matthey, le concept de kleptomanie connait de multiples évolutions au cours du long xixe siècle. Alors qu’il parvient difficilement à se faire reconnaître des magistrats et des aliénistes du premier xixe siècle, il réussit finalement à se maintenir et à s’assoir solidement dans les prétoires de la iiie République. Entre temps, ses caractéristiques évoluent sensiblement en raison des nouvelles découvertes cliniques de l’aliénation mentale et de l’apparition de la fi...

    2005-01-01

    Full Text Available Étudier l'émergence du mouvement libéral en Grèce au XIXe siècle implique une série de difficultés d'interprétation. C'est appréhender un univers qui a été légué par la Révolution française et nous conduit à l'acquisition de principes indispensables au fonctionnement d'une société démocratique moderne. Υ travers des types de discours différents, nous essayons de suivre les traces de cette mise en œuvre du principe de la liberté de 1830 jusqu'à la veille du premier conflit mondial. On assiste après 1830, à une période de transition mais également de mise en œuvre des idées novatrices des Lumières. Les libéraux grecs ont pris fait et cause pour des combats concernant le respect de la vie humaine, la réciprocité des droits et des devoirs et sont dominés par la préoccupation de la liberté d'expression et de création, l'abolition de la peine de mort, l'idéal républicain, l'instruction publique, le défi du progrès. Depuis les années 1830 jusqu'en 1870, se réclamer du libéralisme, c'est s'inscrire dans les forces progressistes. Mais, la dernière phase de son édification fut liée à la montée du socialisme et du marxisme, qu'il allait remettre en question, et dans les années qui ont suivi la défaite de 1897, le libéralisme est confronté à des théories comme la pensée polyvalente de Nietzsche. Dans les différentes phases de l'évolution de la pensée libérale en Grèce, on observe des variations qui pour la plupart sont des étapes du processus vers la démocratie.

    Full Text Available À la fin du XIXe siècle, le journaliste et photographe Jacob Riis révèle les conditions de vie déplorables des familles d’immigrants à New York. C’est le début de la photographie sociale aux États-Unis où la représentation de l’enfant pauvre tiendra une place majeure. Ses photographies, projetées au cours de conférences faites par l’auteur et reproduites dans des publications, contribueront à un changement de mentalité. Si le regard de ce photographe reste celui d’un membre de la classe moyenne sur les enfants du Lower East Side, ses images apportent une nouvelle vision de la pauvreté, en phase avec un enfant désormais perçu comme innocent par la société. Par ailleurs, cet usage particulier du rôle probant de la photographie en soutien du texte inaugure un nouveau mode de communication dont les réformateurs useront afin d’émouvoir et de faire réagir le public des classes moyennes et aisées.At the end of the 19th century, Jacob Riis, journalist and photographer, brought to light the appalling conditions of the slums in New York; it was the beginning of the social documentary photography in the United States. The representation of destitute children was to become central in this genre. His photographs, used during stereopticon slides projections and published in books and articles, contributed to a change of mentality. However influenced by a middle-class vision of the Lower East Side’s children, Jacob Riis’s photographs contributed to bring a new perception of poverty in line with a child who was from that time perceived as innocent by a large part of society. This particular use of photography as a convincing and reliable medium added to the text initiated a new means of communication used by the reformers to move and provoke reactions from a middle and upper-class public.

    Full Text Available L'intérêt du manuel scolaire pour l'histoire des idéologies et des mentalités n'est plus à démontrer, d'autant qu'il se trouve soumis en Espagne à un double contrôle idéologique, tant du pouvoir civil comme des instances religieuses. Vecteurs de systèmes de valeurs, les manuels scolaires servent d'instruments dans la consolidation des formes et des codes moraux et sociaux : défense de la propriété privée, conservation de l'ordre public, protection de l'ordre moral. Dans les manuels de civilité (urbanidad, la jeunesse scolarisée pouvait apprendre les normes essentielles des usages sociaux, les codes, les valeurs, les comportements et les conduites qui définissaient le modèle d'homme et de femme « civilisés » que les classes dominantes prétendaient diffuser pour asseoir leur pouvoir. La civilité vise donc une entreprise de rationalisation, de régulation des conduites, une mise en ordre qui affecte toutes les sphères de la vie, tant privée (espace domestique que publique (école, Église, rue, magasin… et, dans l’ensemble, toutes les activités (travail et loisirs. Au cœur de ce dispositif se retrouvent les notions d'usage, de bienséance (decoro, variable selon les civilisations et les peuples, et de respect : respect de soi-même en premier lieu (hygiène corporelle et tenue vestimentaire, mais toujours vis-à-vis des autres (odeurs, formes, couleurs…, respect des autres (tant êtres humains qu'animaux, et même les plantes. Ces notions sont toutes deux fondées sur l'apparence et le paraître.

    Full Text Available Issue d’une première tentative de synthèse portant sur la peinture monumentale religieuse à Lille dans la seconde moitié du XIXe siècle, cette étude permet d’exhumer l’œuvre d’artistes régionaux, mais également belges et néerlandais, mettant en évidence le rôle de carrefour de l’actuelle métropole lilloise. Dans une région fortement marquée par le catholicisme, les sujets traités sont à la fois le reflet des dévotions nationales et de cultes plus locaux, que ce soit à travers la figure de saint Vincent de Paul, le rôle de la Vierge ou la dévotion aux âmes du purgatoire qui prend une importance particulière à partir du foyer de Loos. Cette expression artistique et religieuse se développe sous la forme de grands cycles dont la réalisation connaît son apogée sous la IIIe République, en particulier de 1880 à 1900. Une fois ce panorama dressé, il devient possible d’interroger les catégories traditionnelles de l’art à cette époque, la notion centrale de primitivisme et les jugements de valeur auxquels cette peinture est encore souvent soumise.This article is based on a synthetic analysis of monumental religious painting at Lille during the second half of the 19th century. This study led to the rediscovery of many regional artists, but also Belgian and Dutch artists, underlining the long history of Lille’s present-day position as an international crossroads. In a region which was strongly marked by Catholicism, the subjects dealt with offer a reflection of national devotional practices but also draw attention to more local cults. Examples here include the figure of Saint Vincent de Paul, the role of the Virgin Mary and the devotion to souls in purgatory, which is particularly important in Loos. This artistic and religious expression develops according to major cycles which reached a high point during the Third Republic, and particularly from 1880 to 1890.

    Full Text Available Les explorateurs européens qui parcourent le Soudan central dans la première moitié du xixe siècle concentrent leurs recherches sur la collecte d’informations géographiques, afin de réunir les matériaux nécessaires à la construction de cartes une fois rentrés en Europe. Pour ce faire, leur méthode est celle d’un recueil systématique et quotidien d’itinéraires auprès de leurs compagnons de voyage et d’informateurs croisés sur les routes ou à l’étape. Certaines de ces listes d’itinéraires nous sont parvenues et nous invitent à tenter de retrouver les pratiques savantes et les imaginaires spatiaux qui les fondent. En les confrontant à des matériaux linguistiques recueillis eux aussi au xixe siècle, on peut replacer ces itinéraires dans le contexte des pratiques de voyage de cette époque au Soudan central. La confrontation de ces documents permet de proposer une mise en récit réaliste des processus qui se sont noués au moment de la rencontre et de donner ainsi du sens à ces objets hybrides, reflets des conceptions de l’espace alors en usage au Soudan central.The European explorers who traveled in the central Sudan during the first half of the 19th century concentrated on gathering the geographical information necessary for drawing maps once they would return to Europe. Their method involved a daily, systematic account of the trips made by the companions and informants whom they met on the road or at places where they stopped over. Some of these lists of itineraries have survived and invite us to try to describe the scientific practices and geographical imagery on which they were based. By comparing them with linguistic data collected during the 19th century, we can place these itineraries in the context of traveling at the time in the central Sudan. This comparison enables us to propose a realistic account of the processes involved in these meetings and to give meaning to these hybrid reflections of the

    Full Text Available Au cours de la première partie du xixe siècle, l’homosexualité masculine est stigmatisée au travers de la figure du pédéraste. Il devient une figure emblématique du désordre, liée à divers fléaux sociaux. Les médecins légistes construisent un personnage personnifiant la transgression d’un ordre sexuel. Cependant, ces discours ont-ils un impact réel sur certains hommes issus des classes populaires urbaines ? On distingue parfaitement deux types d’hommes dans certains fichiers de police. Certains hommes « efféminés » sont affublés du qualificatif de tante. D’autres ne sont pas affublés de ce qualificatif et correspondraient à ceux que Georges Chauncey nomme Trades : ils répondent aux sollicitations des tantes. De plus, certaines libertés d’attitudes, de même que le développement de la prostitution masculine pourraient démontrer le poids limité des discours stigmatisants.Stigmatisation of the male homosexual pratictes and the identifications through limbed of the parisian popular classes during the first part of the XIXth centuryDuring the first part of the xixth century, the male homosexuality is stigmatized through the figure of the pederast.

However, these speeches have a real impact on certain men stemming from urban lower classes? We distinguish perfectly two types of men in certain files of police. Certain feminine are decked out by aunt's qualifier. Others are not decked out by this qualifier and would correspond to those whom Georges Chauncey names Trades: they answer to the requests of the aunts. Furthermore, certain liberties of attitudes, as well as the development of the male prostitution could demonstrate the weight limited by the stigmatizing speeches.

    Full Text Available Cet article analyse les idées et l’œuvre de la directrice de l’École des mères, Augusta Moll-Weiss. Dans le contexte du tournant des XIXe-XXe siècles où l’éloge de la ménagère est un thème récurrent des discours moralisateurs émanant des ouvriers ou des bourgeois, Augusta Moll-Weiss met en place un projet de cours ménagers. Son œuvre offre une approche singulière de ce que des activités reconnues comme typiquement féminines peuvent offrir aux femmes. Loin de former uniquement des « fées du logis », les cours professés à l’École des mères donnent aussi aux élèves la possibilité de se préparer à une carrière professionnelle. Augusta Moll-Weiss imagine alors pléthore de débouchés qui placent les activités « du souci des autres » dans la sphère du travail social. Son engagement en faveur de l’enseignement ménager s’accompagne d’une réflexion sur de nouveaux modèles domestiques susceptibles d’accompagner l’entrée des femmes sur le marché du travail. La rationalisation et le partage sexué des tâches domestiques ainsi que la question du temps partiel sont au cœur de son projet. Aux marges de la philanthropie et du féminisme, Augusta Moll-Weiss s’engage donc dans une stratégie de reconnaissance du rôle des femmes dans l’espace civique. Après avoir présenté l’œuvre scolaire de cette femme, cet article s’intéresse à sa vision de la « Ménagère nouvelle » et à son approche du féminisme.This article explores the ideas and works of the Augusta Moll-Weiss, head of the École des mères. The latter started housewifery lessons at the turn of the 19th century at a moment when public discourse among both working and upper-class reformers sang the praises of the housewife.

    2016-01-01

    This book, comprising contributions presented at the XIX Edoardo Amaldi Conference, examines important aspects of international cooperation aimed at enhancing nuclear safety, security, safeguards (the “3S”), and non-proliferation, thereby assisting in the development and maintenance of the verification regime and progress toward a nuclear weapon-free world. The Conference served as a forum where eminent scientists, diplomats, and policymakers could compare national perspectives and update international collaborations. The book opens by addressing the political, institutional, and legal dimensions of the 3S and non-proliferation; current challenges are discussed and attempts made to identify possible solutions and future improvements. Subsequent sections consider scientific developments that can contribute to increased effectiveness in the implementation of international regimes, particularly in critical areas, technology foresight, and the ongoing evaluation of current capabilities.

As a test case, we applied this new tool to the published phylome of Salinibacter ruber, a species of halophilic Bacteriodetes, identifying 13 unique sister relationships to S. ruber across the 4,589 gene phylogenies. S. ruber grouped with bacteria, most often other Bacteriodetes, in the majority of phylogenies, but 91 phylogenies showed a branch-supported sister association between S. ruber and Archaea, an evolutionarily intriguing relationship indicative of horizontal gene transfer.

    Effect of the hydrogen radical on the reduction of a silicon tetrachloride (SiCl4) source was studied. The hydrogen radicals were generated using a tungsten (W) filament in a generation chamber, and were remotely supplied to another reaction chamber. The density of the hydrogen radical was estimated from the optical transmittance of 600-nm-wavelength light through phosphate glass doped with tungsten oxide (WO3). Lifetime of the hydrogen radical seemed sufficiently long, and its density as supplied to the reaction chamber was estimated to be on the order of 1012 cm‑3. Signal intensity of the peak corresponding to SiCl4 (m/z = 170) detected by quadrupole-mass measurement was confirmed to decrease owing to the reaction with the remotely-supplied hydrogen radical. This indicates the possibility that chemically-stable SiCl4, as one of the by-products of the Siemens process, can be reduced to produce silicon.

  17. Enhancement of microelectronic device performances by photothermal annealing under SiCl4 ambient

    2006-01-01

    The use of low cost silicon wafers seems to be very attractive for photovoltaic and microelectronic devices. However, this material is widely contaminated by different impurities particularly transitions metals, which deteriorate the lifetimes and the bulk diffusion lengths of the minority charge carriers. One possible way to overcome this undesirable behavior is to include an efficient purification technique in the process of device fabrication. In this work, we present the effect of photothermal treatments of monocrystalline Czochralski silicon substrates under SiCl 4 /N 2 atmosphere using a thin sacrificial porous silicon layer. The main results show a decrease of the resistivity over 40 μm depth. The Hall mobility of the majority charge carriers is improved from 300 to 1417 cm 2 V -1 s -1 . The capacitance-voltage (C-V) characteristics of metal/SiO 2 /Si (MIS) structures indicate a decrease of carrier concentration which confirms the results obtained by Hall Effect and Van Der Pauw method. The reduction of boron concentration in Czochralski silicon may reduce boron- and oxygen related metastable defect centers

    Full Text Available However, historically, Samin resistance by the end of XIX centery was sparked by two main issues, eg. forestry and taxation. Historical explanation on the fist issue, the relationship between Samin movement and forestry, is rarely discussed. On the other hand, Samin’s spiritual values—based on Adam religion teaching—are also frequently ignored from causalities discussion. The Samin’s Movement at XIX century showed the values they fiht for are religiosity, ethics of life, political ethics, farming knowledge, and forest point of view. The knowledge systems of farming based on their high appreciation for human being role in altering nature become food. On the other hand, the Java land, inclusive of forest in it is Entrusted by God creation of Pandawa to Javanese.

    The state-selective dissociation dynamics for anionic and excited neutral fragments of gaseous SiCl 4 following Cl 2p and Si 2p core-level excitations were characterized by combining measurements of the photon-induced anionic dissociation, x-ray absorption and UV/visible dispersed fluorescence. The transitions of core electrons to high Rydberg states/doubly excited states in the vicinity of both Si 2p and Cl 2p ionization thresholds of gaseous SiCl 4 lead to a remarkably enhanced production of anionic, Si - and Cl - , fragments and excited neutral atomic, Si*, fragments. This enhancement via core-level excitation near the ionization threshold of gaseous SiCl 4 is explained in terms of the contributions from the Auger decay of doubly excited states, shake-modified resonant Auger decay, or/and post-collision interaction. These complementary results provide insight into the state-selective anionic and excited neutral fragmentation of gaseous molecules via core-level excitation.

    2008-01-01

    Inductively coupled plasma etching of GaSb using BCl 3 /SiCl 4 etch chemistry has been investigated. The etch rates were studied as a function of bias power, inductively coupled plasma source power, plasma chemistry and chamber pressure. The etched surfaces remain smooth and stoichiometric over the entire range of plasma conditions investigated. The knowledge gained in etching GaSb was applied to etching AlGaAsSb and InGaAsSb in order to fabricate heterojunction phototransistors. As expected, InGaAsSb etch rate was much lower compared to the corresponding value for GaSb, mainly due to the relatively low volatility of indium chlorides. For a wide range of plasma conditions, the selectivity between GaSb and AlGaAsSb was close to unity, which is desirable for fabricating etched mirrors and gratings for Sb-based mid-infrared laser diodes. The surface roughness and the etch profile were examined for the etched GaSb, AlGaAsSb and InGaAsSb samples using scanning electron microscope. The high etch rates achieved (∼ 4 μm/min) facilitated deep etching of GaSb. A single layer, soft mask (AZ-4903 photoresist) was used to etch GaSb, with etch depth ∼ 90 μm. The deep dry etching of GaSb has many important applications including etching substrate windows for backside-illuminated photodetectors for the mid-infrared wavelength range

    In nucleus-nucleus collisions the initial relative kinetic energy of target and projectile is available for internal excitation of the interacting system; it is however still not well established to what extent local equilibrium and thermalisation occur. Local equilibrium is of interest to derive, within the formalism of transport equations and of the equation of state, (EOS), general properties of compressed and excited nuclear matter. Such approach describes in relatively simple terms the complex many body interactions occuring within extended baryonic and hadronic (or quark) matter. For a basic microscopic understanding it is highly desirable to investigate the elementary in-medium interactions in relation to the free elementary processes. Excitation function measurements of central collisions between the heaviest available nuclei (like Au on Au), supply the best ground for such studies: the highest degree of thermalisation and compression is expected for such reactions. The consideration presented here of energy thermalisation and of an expanding system clusterizing at freeze-out in a situation close to the liquid gas phase transition can be of interest to astrophysics as well as to the quark gluon plasma deconfinement studied in nucleus-nucleus collisions at the higher energy regime of CERN and Brookhaven.

    Strong white and blue photoluminescence (PL) from as-grown silicon nanocrystals (nc-Si) in SiN x films prepared by remote plasma enhanced chemical vapour deposition using SiCl 4 /NH 3 mixtures is reported. The colour and intensity of the PL could be controlled by adjusting the NH 3 flow rate. Samples with white emission were annealed at 1000 deg. C, obtaining a strong improvement of the PL intensity with a blue colour. The PL can be attributed to quantum confinement effect in nc-Si embedded in SiN x matrix, which is improved when a better passivation of nc-Si surface with chlorine and nitrogen atoms is obtained. The size, density and structure of the nc-Si in the as-grown and annealed films were confirmed and measured by high-resolution transmission electron microscopy

During this period, the sociological bonds between the different Greek embryonic minorities, suggest a nuclear colony. The wave of new-comers from the Island of Chios precipitated some major changes in the Marseille Greek’s social morphology: they introduced a social crystallization process through which the archontal Generation (1825-1875 incorporated the long-term representations of the group (religion, language, self-administration policy and kinship, into its main identification frame, the Community. At the same time, this Generation elaborated its own social model through a selective acquisition of local French representations and values.

    The XIX International Youth School on Coherent Optics and Optical Spectroscopy (COOS2015) was held in Kazan, Russia, from October 5 to October 7 at the Nikolai Lobachevsky Scientific Library of Kazan Federal University. The School follows the global tendency toward comprehensive studies of matter properties and its interaction with electromagnetic fields. Since 1997 more than 100 famous scientists from USA, Germany, Ukraine, Belarussia and Russia had plenary lecture presentations. This is the right place, where over 1000 young scientists had an opportunity to participate in hot discussions regarding the latest scientific news. Many young people have submitted interesting reports on photonics, quantum electronics, laser physics, quantum optics, traditional optical and laser spectroscopy, non-linear optics, material science and nanotechnology. Here we are publishing the full-size papers prepared from the most interesting lectures and reports selected by the Program Committee of the School. (paper)

No obstante, la valoración de esta producción historiográfica ha sido realizada de manera parcial y desde una perspectiva muy general.

Among the transforming States no classical empires, but the experience of building a large state formations can be used for understanding what needs to be done to preserve the integrity of States. This article addresses the question of institutional conditions of integration of economic space in the Russia of the XIX century. If we understand economy as "an institutionalized process" movement of material goods and transactions that link economic acts in the sphere of exchange makes this process stability and integrates it into the system companies. The authors considered promising idea Polanyi's three forms of integration or sharing that reproduce the economy as a whole, for the conducting institutional analysis of economy of the Russian Empire of the XIX century. We are talking about market exchange, redistribution (redistribution and of reciprocity (reciprocity, gift exchange. In this aspect, the Russian economy has not yet considered in the economic literature. The main method used institutional analysis and the historical method of research. The materials contained in the work, can be used to consider contemporary problems of integration of heterogeneous economic space. Found that to ensure the system coherence of the society and co-storage state, it is necessary to implement long-term goals in the form of Large projects. The authors consider such projects in the symbolic context of maintaining the legitimacy of power and, in purely economic aspect.

    In this talk I will review PHOBOS data on charged particle multiplicities, obtained in Au+Au and d+Au collisions at RHIC. The general features of the Au+Au pseudorapidity distributions results will be discussed and compared to those of /line{p}p collisions. The total charged particle multiplicity, scaled by the number of participant pairs, is observed to be about 40% higher in Au+Au collisions than in /line{p}p and d+Au systems, but, surprisingly at the same level of e+e- collisions. Limiting fragmentation scaling is seen to be obeyed in Au+Au collisions.

Les « touristes romantiques » découvrent le côté « pittoresque » d’un pays, jadis appelé « Pays des loups », et diffusent, par le biais de leurs récits, la première propagande touristique pour le Luxembourg. Parallèlement aux regards bienveillants des visiteurs de passage, les Luxembourgeois prennent conscience de leur patrimoine et de sa valorisation. Soucieux de montrer les beautés d’un pays qui, au niveau politique, intellectuel, culturel et économique, s’émancipe au XIXe siècle, quelques pionniers dont l’hôtelier Alexis Heck s’engagent dans le destination management du Luxembourg. Aidés par les nouvelles technologies de la mobilité, les protagonistes du tourisme donnent l’exemple aux autorités publiques qui suivent très vite l’initiative privée pour transfigurer les préoccupations touristiques en une « industrie nationale ». La promotion du pays, qui inclut le tourisme collectif et récréatif, va de pair avec l’affirmation de l’indépendance du Luxembourg.

    Full Text Available The article discusses a unique Belyana barge, which was built in the Nizhny Novgorod region for several centuries. Belyana as a type of vessels was designed for transportation of logs, sleepers, beams, planks and other forest products from the Upper to the Lower Volga. Originally, the center of Belyana construction was the village of Baki, which was situated on the Vetluga River, a tributary of the Volga River. The Belyana construction technique spread from the Vetluga river banks further to Nizhny Novgorod, and then to Perm region. Almost all aspects of Belyana construction starting from the logging finishing with its floating to the lower Volga, and also cost of transported products in the prices of the XIX century are disclosed. Due to Belyana is truly a popular invention, it was built by traditional methods, relying solely on the centuries-old experience. Any drawings for the construction never existed, that’s why the author relied on preserved photographs and drawings in the historical reconstruction of this unique vessel. At the beginning of the article a brief overview of the geographical location of Nizhny Novgorod, as well as the names of wooden ships which were sailing on Volga and its tributaries in the same times with Belyana are given. At the end of the article practical recommendations on possible reconstruction of Belyana and using it as an interactive museum of ethnography are given.

    Full Text Available Para este ensayo se empleó información secundaria publicado en revistas y libros que documentan el origen de la actividad silvícuola, coincidiendo y aun antecediendo al desarrollo de la agricultura. Luego se centra en la transformación de esta actividad en una ciencia, la silvicultura, o más propiamente, la dasonomía, la cual se consolidó desde mediados del siglo XVIII cuando se empezó a enseñar formalmente en Alemania y otros países germánicos y se crearon, además, servicios forestales como el de Prusia. De esta época datan los primeros conceptos teóricos del rendimiento sostenido de los bosques (G. L. Harting, H. von Cotta, aunque desde comienzos del siglo XIII ya existían bosques empíricamente ordenados con esta filosofía en el Centro de Europa. La sustentabilidad o sostenibilidad tan en boga hoy en la ecología y la economía, tiene allí su antecedente más remoto. También Francia jugó un papel preponderante en el desarrollo de la dasonomía, sobre todo por haber involucrado el manejo de las cuencas hidrográficas dentro de las ciencias forestales, en tanto que los aportes de los germanos fueron en economía y medición forestal. El origen de la profesión forestal parece situarse tanto en los guardabosques ingleses como en los maestros de aguas y bosques franceses, de principios de los siglos XII y XIII, respectivamente. Durante el periodo analizado las ciencias forestales evidenciaron relaciones estrechas con las ciencias agropecuarias con las cuales parece haberse asociado sólo durante el presente siglo por razones coyunturales. El siglo XIX vio nacer la silvicultura tropical en la India; los primeros profesores e investigadores fueron alemanes contratados por la corona inglesa. También en América fueron forestales alemanes quienes fundaron en Estados Unidos de América la primera escuela forestal y contribuyeron a crear el Servicio Forestal de dicho país.

    The magnetic susceptibility of liquid Cr-Au, Mn-Au, Fe-Au and Cu-Au alloys was investigated as a function of temperature and composition. Liquid Cr{sub 1-c}Au{sub c} with 0.5 ≤ c and Mn{sub 1-c}Au{sub c} with 0.3≤c obeyed the Curie-Weiss law with regard to their dependence of χ on temperature. The magnetic susceptibilities of liquid Fe-Au alloys also exhibited Curie-Weiss behavior with a reasonable value for the effective number of Bohr magneton. On the Au-rich side, the composition dependence of χ for liquid TM-Au (TM=Cr, Mn, Fe) alloys increased rapidly with increasing TM content, respectively. Additionally, the composition dependences of χ for liquid Cr-Au, Mn-Au, and Fe-Au alloys had maxima at compositions of 50 at% Cr, 70 at% Mn, and 85 at% Fe, respectively. We compared the composition dependences of χ{sub 3d} due to 3d electrons for liquid binary TM-M (M=Au, Al, Si, Sb), and investigated the relationship between χ{sub 3d} and E{sub F} in liquid binary TM-M alloys at a composition of 50 at% TM.

    We present B, V time-series photometry of Andromeda XIX (And XIX), the most extended (half-light radius of 6.'2) of Andromeda's dwarf spheroidal companions, which we observed with the Large Binocular Cameras at the Large Binocular Telescope. We surveyed a 23' × 23' area centered on And XIX and present the deepest color-magnitude diagram (CMD) ever obtained for this galaxy, reaching, at V ∼ 26.3 mag, about one magnitude below the horizontal branch (HB). The CMD shows a prominent and slightly widened red giant branch, along with a predominantly red HB, which extends to the blue to significantly populate the classical instability strip. We have identified 39 pulsating variable stars, of which 31 are of RR Lyrae type and 8 are Anomalous Cepheids (ACs). Twelve of the RR Lyrae variables and three of the ACs are located within And XIX's half light radius. The average period of the fundamental mode RR Lyrae stars ((P {sub ab}) = 0.62 days, σ = 0.03 days) and the period-amplitude diagram qualify And XIX as an Oosterhoff-Intermediate system. From the average luminosity of the RR Lyrae stars ((V(RR)) = 25.34 mag, σ = 0.10 mag), we determine a distance modulus of (m – M){sub 0} = 24.52 ± 0.23 mag in a scale where the distance to the Large Magellanic Cloud (LMC) is 18.5 ± 0.1 mag. The ACs follow a well-defined Period-Wesenheit (PW) relation that appears to be in very good agreement with the PW relationship defined by the ACs in the LMC.

The private and eclesiastic charity of the Old Regime begins to transform in public charity although marginal society still receives the same treatment, which basically intends their moralization. Basic elements of this moralization were work and education, that are the main points of this article, which in particular refers to charity establishments. Work and education for the poors were requirements that were reiterated in the writings of philantropists, politicians and moralists, following the tradition of the preceding centuries, and which were written into the legislation of the XIX century, the same as in the statutes of the poor houses. An always basic education and with a strong practical character, that intended basically to neutralize the risks of social dangers, transmitting the values of the dominant society.

    1975-12-01

    The 36-levels model atom Fe/sup +16/ of Loulergue and Nussbaumer (1973) is extended to a 51-levels atom including n=4 configuration. The earlier conclusion that relative intensities among the Fe XVII lines are not sufficiently sensitive to variations in electron densities and electron temperature to deduce these parameters from observed intensity ratios still holds. Discrepancies between calculated and observed relative intensities in Fe XVII and Ni XIX are attributed to blends or misidentifications.

    Full Text Available El presente artículo permitió generar una serie de categorías de castigos femeninos, considerando que durante buena parte del siglo XIX la policía pudo aplicar "justicia correccional", es decir, sancionar delitos menores. De un universo de más de 32.000 arrestos efectuados en la ciudad de Santiago de Chile entre los años 1830 a 1840 y utilizando el criterio "femenino", el levantamiento logró una muestra que alcanzó al 12% del total. Los datos sistematizados permiten señalar que durante la primera mitad del siglo XIX el delito femenino fue parte importante de la actividad represiva en Chile y dio origen a un castigo relacionado a la Cárcel Correccional. Aunque también se observan otras penas como trabajo de casa formal o encierro en monasterios, forman parte de un circuito restrictivo en función del encierro de mujeres.The present article allowed to generate a series of categories of female punishments, considering that during a great part of the XIX century the police could apply "correctional justice", in other words, punish minor offences.

The systematized information shows that during the firt half of the xix century the female offence was an important part of the repressive activity in Chile and it gave origin to a punishment related to a correctional. Even though some other punishments were observed such a work in a formal house or monastery confinemet, they formed part of a restricting circuit functioning with the confinement of women.

    We present here a technological platform for engineering Au nanotopographies by templated electrodeposition on antibacterial surfaces. Three different types of nanostructures were fabricated: nanopillars, nanorings and nanonuggets. The nanopillars are the basic structures and are 50 nm in diameter and 100 nm in height. Particular arrangement of the nanopillars in various geometries formed nanorings and nanonuggets. Flat surfaces, rough substrate surfaces, and various nanostructured surfaces were compared for their abilities to attach and kill bacterial cells. Methicillin-resistant Staphylococcus aureus, a Gram-positive bacterial strain responsible for many infections in health care system, was used as the model bacterial strain. It was found that all the Au nanostructures, regardless their shapes, exhibited similar excellent antibacterial properties. A comparison of live cells attached to nanotopographic surfaces showed that the number of live S. aureus cells was flat and rough reference surfaces. Our micro/nanofabrication process is a scalable approach based on cost-efficient self-organization and provides potential for further developing functional surfaces to study the behavior of microbes on nanoscale topographies.We present here a technological platform for engineering Au nanotopographies by templated electrodeposition on antibacterial surfaces.

    We present the cluster-to-cluster transformations among three gold nanoclusters, [Au6(dppp)4]2+ (Au6), [Au8(dppp)4Cl2]2+ (Au8) and [Au11(dppp)5]3+ (Au11). The conversion process follows a rule that states that the transformation of a small cluster to a large cluster is achieved through an oxidation process with an oxidizing agent (H2O2) or with heating, while the conversion of a large cluster to a small one occurs through a reduction process with a reducing agent (NaBH4). All the reactions were monitored using UV-Vis spectroscopy and ESI-MS. This work may provide an alternative approach to the synthesis of novel gold nanoclusters and a further understanding of the structural transformation relationship of gold nanoclusters.

    2014-01-01

    We present spatially resolved EUV spectroscopic measurements of pervasive, faint Fe XIX 592.2 Å line emission in an active region observed during the 2013 April 23 flight of the Extreme Ultraviolet Normal Incidence Spectrograph (EUNIS-13) sounding rocket instrument. With cooled detectors, high sensitivity, and high spectral resolution, EUNIS-13 resolves the lines of Fe XIX at 592.2 Å (formed at temperature T ≈ 8.9 MK) and Fe XII at 592.6 Å (T ≈ 1.6 MK). The Fe XIX line emission, observed over an area in excess of 4920 arcsec 2 (2.58 × 10 9 km 2 , more than 60% of the active region), provides strong evidence for the nanoflare heating model of the solar corona. No GOES events occurred in the region less than 2 hr before the rocket flight, but a microflare was observed north and east of the region with RHESSI and EUNIS during the flight. The absence of significant upward velocities anywhere in the region, particularly the microflare, indicates that the pervasive Fe XIX emission is not propelled outward from the microflare site, but is most likely attributed to localized heating (not necessarily due to reconnection) consistent with the nanoflare heating model of the solar corona. Assuming ionization equilibrium we estimate Fe XIX/Fe XII emission measure ratios of ∼0.076 just outside the AR core and ∼0.59 in the core.

    Atomic data consisting of energy levels, g f-values and wavelengths are presented for the Fe XIX 2s 2 2p 4 -2s 2 2p 3 3s, 2s 2 2p 3 3d arrays that give rise to lines in solar flare and active-region X-ray spectra. Collision strengths and theoretical intensity ratios are given for the 2s 2 2p 4 -2s 2 2p 3 3d lines, which occur in the 13.2-14.3 A range. Solar spectra in this range include a large number of other intense lines, notably those due to He-like Ne (Ne IX). Although the Ne IX lines are potentially the most useful indicators of electron density in solar X-ray spectra, blending with the Fe XIX lines has been a major problem for previous analyses. Comparison of observed spectra with those calculated from the Fe XIX atomic data presented here and Ne IX lines from other work indicates that there is generally good agreement. We use the calculated Fe XIX and Ne IX line spectra and several observed spectra during a flare previously analysed to estimate electron density from Ne IX line ratios, thus for the first time properly taking into account blends with Fe XIX lines.

    AMD-V is an optimum model for calculation of multifragmentation in Au + Au collisions. AMD-V consider anti-symmetry of incident nucleus, target nucleus and fragments, furthermore, it treat the quantum effect to exist many channels in the intermediate and final state. 150 and 250 MeV/nucleon incident energy were used in the experiments. The data of multifragment atom in {sup 197}Au + {sup 197}Au collisions was reproduced by AMD-V calculation using Gognny force, corresponding to the imcompressibility of nuclear substance K = 228 MeV and its mean field depend on momentum. When other interaction (SKG 2 force, corresponding to K = 373 KeV) was used an mean field does not depend on momentum, the calculation results could not reproduce the experimental values, because nucleus and deuteron were estimated too large and {alpha}-particle and intermediate fragments estimated too small.

    Full Text Available The article considers the question of forms of wages paid to workers in the mining industry of Siberia in the late XIX – early XX centuries. Of the two main forms of labor compensation – hourly rate and piecework pay, the latter was more corresponding to the spirit of capitalism, and it was most widespread in the mining enterprises of Siberia. The piecework pay was also the main instrument for intensifying labor productivity. This episode in the history of labor is studied on the basis of paperwork materials of mining companies and reporting documents of the mining inspectorate.

  1. Impact de la forêt sur l’évolution des ressources en eau en moyenne montagne alpine depuis le milieu du XIXe siècle (massif de Chartreuse, France

    Directory of Open Access Journals (Sweden)

    2012-02-01

    Full Text Available Depuis la révolution industrielle, une grande partie des terres des espaces de moyenne montagne a été abandonnée au profit d’une extension de la couverture forestière. Or, la forêt intercepte et retient un pourcentage plus ou moins élevé des pluies sur son feuillage, diminuant du même coup la quantité d’eau réellement reçue par le sol. Le transfert de l’eau atmosphérique en une eau utilisable comme ressource a donc été progressivement modifié au cours de ces dernières décennies par la transformation progressive du paysage. Dans cette étude, conduite à l’échelle du massif de Chartreuse, la pluviométrie annuelle, le rôle de la forêt dans l’interception des pluies et l’extension de la forêt, sont appréciés tour à tour. L’impact de l’extension de la forêt depuis le milieu du XIXe siècle sur les quantités d’eau perdues pour l’écoulement et les réserves souterraines peut ainsi être évalué. Cette étude montre que, depuis le milieu du XIXe siècle, l’extension de la couverture forestière en Chartreuse aurait accru de presque 100 mm les pertes en eau par les processus d’interception. Et, sur cette même période, cette quantité d’eau perdue n’a pas été compensée par une hausse des précipitations. Au total, le bilan hydrologique a donc été notablement modifié, avec une quantité d’eau disponible pour l’écoulement, ou les réserves souterraines, plus réduite que celle définie traditionnellement à partir des uniques relevés météorologiques.

    The palette of some of the most representative Brazilian painters from the XIX century was characterized using EDXRF technique. In this work were analyzed paintings of: Eliseu Visconti, Almeida Junior, Rodolfo Amoedo, Henrique Bernardelli, Rafael Frederico, Modesto Brocos, Augusto Rodrigues Duarte and Pedro Peres - all of them belonging to the National Museum of Fine Arts Collection. EDXRF measurements were carried out with a portable system developed by the Nuclear Instrumentation Laboratory, consisting of an X-ray tube Oxford TF3005 with tungsten (W) anode, operating at 25 kV and 100 μA, and a Si-PIN XR-100CR detector from Amptek. In each color and distinct hue of the paint layer were obtained several spectra, with an acquisition time of 300 s and a beam collimation of 2 mm. The spectra were processed and analyzed using the software QXAS-AXIL from IAEA. Some pigments used by the artists were: zinc white, lead white, ochre, umbra, vermilion, Prussian blue, cobalt blue, cadmium yellow, black iron oxide, manganese violet, etc. These results - together with the Computed Radiography analyses - have been used to create a database about the XIX century collection of the National Museum of Fine Arts, in order to assist restorators, conservators, art students and researchers in the field of archaeometry

    Full Text Available El sueño de una inmigración europea, concebido como instrumento de modernización de la sociedad, figura sin duda entre los rasgos comunes de la cultura política hispanoamericana del siglo XIX; por lo tanto, Colombia se diferencia por su imposibilidad de transformar ese sueño en realidad. Más que la historia de un flujo de poblaciones, el tema de la inmigración en la Colombia del siglo XIX se da como una sucesión de leyes, proyectos, debates, análisis del fracaso, prevenciones. En esto, ofrece un observatorio privilegiado del imaginario de los grupos dirigentes en cuanto a la densidad "civilizadora", o al contrario " perturbadora", de una población europea importada: sin que haya recibido nunca flujos importantes de gentes, Colombia vivirá, casi con la misma intensidad que los otros países hispanoamericanos, el debate sobre los beneficios y los peligros de la inmigración.

En mi caso, siempre recordaré aquel día de 1990 en que Rosario Camacho, en la asignatura Arte español de la Licenciatura de Geografía e Historia, nos llevó al grupo de cuarto curso de paseo por la Málaga del siglo XIX. Nunca hasta entonces ese importante pasado decimonónico de la ciudad se me había aparecido tan esclarecedor como cuando nos iba desentrañando casas, iglesias y edificios públicos con el conocimiento y la profundidad que siempre han caracterizado a la gran maestra del Departamento de Arte. Si bien la principal especialidad de Rosario Camacho ha sido la arquitectura y la cultura del barroco en general, la versatilidad y la apertura de miras han sido dos de los rasgos definitorios de su labor investigadora. No hay más que ver esta sección del Boletín de Arte para darse cuenta de tal diversidad de intereses. Y de entre estos temas «tangenciales» a los que siempre ha atendido más allá de lo barroco, se encuentran el urbanismo y la arquitectura de la Málaga del XIX.

    Full Text Available The article deals with the issues of censorship and printing in the Caucasus at the end of XIX – early XX centuries. The special attention is given to censorship during the First Russian revolution (1905-1907 years. Among the materials are the archival documents from the national archives of Georgia, as well as materials of pre-revolutionary periodicals and legislation dedicated to this issue. The scientific publications are important too. The authors come to the conclusion that in the late of XIX – early XX centuries in the Caucasus, as in the whole of the territory of the Russian Empire, there was a sharp rise of printing and publishing periodicals – magazines. With the growth of revolutionary events there was a need in the institute of censorship to control over the printed word. Especially the role of this institution was high during the First Russian revolution. Despite the small number of states and different problems, the censorship has contributed to the stabilization of the political and crime situation in the territory of the Caucasian viceroyalty.

    Invariant transverse-velocity spectra of intermediate-mass fragments were measured with the 4π multi-detector system INDRA for collisions of 197 Au on 197 Au at incident energies between 40 and 150 MeV per nucleon. Their scaling properties as a function of incident energy and atomic number Z are used to distinguish and characterize the emissions in (i) peripheral collisions at the projectile and target rapidities, and in (ii) central and (iii) peripheral collisions near mid-rapidity. The importance of dynamical effects is evident in all three cases and their origin is discussed. (orig.)

  16. Chiral magnetic effect search in p+Au, d+Au and Au+Au collisions at RHIC

    Science.gov (United States)

    Zhao, Jie

    2018-01-01

    Metastable domains of fluctuating topological charges can change the chirality of quarks and induce local parity violation in quantum chromodynamics. This can lead to observable charge separation along the direction of the strong magnetic field produced by spectator protons in relativistic heavy-ion collisions, a phenomenon called the chiral magnetic effect (CME). A major background source for CME measurements using the charge-dependent azimuthal correlator (Δϒ) is the intrinsic particle correlations (such as resonance decays) coupled with the azimuthal elliptical anisotropy (v2). In heavy-ion collisions, the magnetic field direction and event plane angle are correlated, thus the CME and the v2-induced background are entangled. In this report, we present two studies from STAR to shed further lights on the background issue. (1) The Δϒ should be all background in small system p+Au and d+Au collisions, because the event plane angles are dominated by geometry fluctuations uncorrelated to the magnetic field direction. However, significant Δϒ is observed, comparable to the peripheral Au+Au data, suggesting a background dominance in the latter, and likely also in the mid-central Au+Au collisions where the multiplicity and v2 scaled correlator is similar. (2) A new approach is devised to study Δϒ as a function of the particle pair invariant mass (minv) to identify the resonance backgrounds and hence to extract the possible CME signal. Signal is consistent with zero within uncertainties at high minv. Signal at low minv, extracted from a two-component model assuming smooth mass dependence, is consistent with zero within uncertainties.

    Thermodynamics phase diagram of ZrB 2 –SiC co-deposited from precursors of ZrCl 4 –BCl 3 –CH 3 SiCl 3 (methyltrichlorosilane, MTS)–H 2 –Ar has been investigated in detail by using the FactSage code and its embedded database (130 species being involved). The yields of condensed phases in the co-deposition process have been examined as the functions of the inject reactant ratios of BCl 3 / (BCl 3 + MTS) and H 2 / (ZrCl 4 + BCl 3 + MTS), and the temperature at a fixed pressure of 5 kPa. The results show that their yields strongly depend on the molar ratios of the inject reactants and the temperature. Consequently, the pure ZrB 2 –SiC composite without free C, B 4 C, ZrC and ZrSi can be co-deposited under the ideal condition by adjusting the reactant ratios and the temperature. The gas-phase equilibrium concentration distribution shows that the high input amount of H 2 is favorable for the co-deposition of ZrB 2 and SiC at a fixed ratio of ZrCl 4 :BCl 3 :MTS:Ar. In the end, the theoretical results can lay down guidelines for increasing the experimental yields of ZrB 2 and SiC. - Highlights: ► The exact ratio of ZrB 2 and SiC could be obtained by adjusting input gas ratios. ► The other condensed phase species could appear under some suitable conditions ► The H 2 acting as reaction species directly influences the deposition process. ► The high H 2 input amount is favorable for the co-deposition of ZrB 2 and SiC. ► The flow rate range of the H 2 pump should be increased in the experimental study.

    Full Text Available The reading, transcription and systemisation of governmental sources related to work and teaching associations in Recife and Olinda, during the XIX century, revealed practices linked mainly to individual benefits and political gains in its relations with public power. When tracking the specific path and demands of members of the 1872 Sociedade Propagadora da Instrução Pública as well as the petitions done by the teachers to the public power in the main working shifts of teaching - salaries, gratifications, exchanges, medical licenses, transferences, educational material etc - we will argue, using the methodology of microanalysis (REVEL, 1998, that the teachers as a working category was marked by individual practices of citizenship. In this sense, although there were associations, of “common interests” and a “discomfort” of public teachers, those developed personal strategies, according to the privileges acquired along their career which in fact deviate from building a teacher identity

    The pigment vermilion (HgS) was used to color the fore edge, tail and head of books. Dissemination and quantification of Hg present in the ink used to color books from XVIII and XIX centuries are reported. Mercury is a very toxic element for the human body, therefore it is extremely important to know whether Hg tends to disseminate throughout the paper or stays confined to the borders of the books with less danger for readers. Synchrotron X-ray microprobe was used to evaluate Hg dissemination from the border to the centre of the paper sheet. The diffusion pattern of Hg was compared with the results obtained by a portable X-ray fluorescence spectrometer and mean quantitative calculations were obtained by a stationary X-ray fluorescence system with triaxial geometry. The results showed high concentrations of Hg in the external regions, but no diffusion was observed for the inner parts of the paper.

Naumenko (1852-1919 – an outstanding representative of the Ukrainian intelligentsia of the late XIX – early XX century, politics, philologist, publisher, teacher. The scientist's career was developing under the influence of liberatory ideas during this period. The numerous works of eminent historians, who were contemporaries of V.P. Naumenko and researchers late XX – early XXI century, evidenced about it. Analysis of documentary materials proved that the impetus for an active social life of Vladimir Naumenko was family upbringing where service people attached great importance. The University of St. Vladimir in Kiev, where he was enrolled like a free listener in the 1868 had significant impact on the formation of personality and socio-political position of V.P. Naumenko. Scientist's activities in Kiev society where he held «right» liberal wing played an important role in his socio-political life. Vladimir Pavlovich along with other members of the «right» wing did not mind the ideas of socialism, but they treated them as a distant prospect. V.P. Naumenko saw the path to this ideal in peaceful reforms. V.P. Naumenko was also an active member of the liberal-democratic union – Ukrainian common nonpartisan democratic organization (UCNDO. Soon Vladimir Pavlovich stepped back from this participation, because in the early twentieth century the organization began to acquire a political character. Thus, the article analyzed V.P. Naumenko's socio-political activities and elucidate his role in the political process since the middle of the XIX century till the 1917 revolution.

Un tableau synoptique résume les dates disponibles sur les pluies et les inondations de la côte nord du Pérou et comprend une critique des sources historiques ainsi qu’un essai de classification des anomalies climatiques. L’analyse des sources présentées ici conduit les auteurs à mettre en doute la reconstitution de l’avènement, ou de l’intensité, de certains évènements El Niño telles qu’elles ont été proposées par certains auteurs (Quinn et al., 1987. El establecimiento de una cronología de las ocurrencias del fenómeno El Niño en los últimos siglos tiene mucha trascendencia para los investigadores que estudian este tipo de alteración casi periódica del clima del globo terráqueo.

    1996-01-01

    Many interesting results have been obtained for Au + Au reactions at AGS. The basic information about the reaction dynamics comes from the hadronic distribution. and this article reviews the recent progress of these distributions in details. The proton rapidity distribution shows significantly increased stopping compared to lighter systems, implying the formation of a state of high baryon density. Unlike reactions at this energy induced by lighter heavy ions, at low m t - m 0 the proton invariant spectra deviate from a single exponential shape and become fear,. while pion spectra are found to rise in this region, with the π - spectra rising faster than the π + spectra. The inverse slope parameter increases faster for particles of larger mass as the number of participants in the reaction increases, an indication of increased effect of radial expansion in central collision. Anti-proton Needs have been measured recently, and unfortunately a comparison among current results from different experiments indicates discrepancy

    Full Text Available Les villes balnéaires et thermales accordent une large place à l’orientalisme. En France, cet orientalisme a tendance à se confondre en grande partie avec l’histoire de la perception de l’architecture islamique. Il participe à la redécouverte du mythe méditerranéen conçu au XIXe siècle ; dans la seconde moitié du siècle, cette représentation se marie avec le goût éclectique. Au cours de la première moitié du XXe siècle, la référence à l’Orient est porteuse d’autres valeurs culturelles, sa présence se fait plus discrète et évolue vers une conception plus épurée et régionaliste, qui se veut intégrée au monde méditerranéen.Seaside and spa resorts had a serious weakness for orientalism. In France, this orientalism can be placed within a larger historical context of how Islamic architecture was perceived. It belongs to the rediscovery and redefinition of the Mediterranean myth during the 19th century. During the second half of this century, it was a style that blended well with eclectic tastes. During the first half of the 20th century, architectural references to the Orient came to bear other cultural values. The orientalism became more discreet and evolved towards a style that was more refined and regionalist, seeing itself as an integral part of the Mediterranean world.

  11. How Does Amino Acid Ligand Modulate Au Core Structure and Characteristics in Peptide Coated Au Nanocluster?

    The atomic structures and the corresponding physicochemical properties of peptide coated Au nanoclusters determine their distinctive biological targeting applications. To learn the modulation of amino acid ligand on the atomic structure and electronic characteristics of coated Au core is the fundamental knowledge for peptide coated Au nanocluster design and construction. Based on our recent coated Au nanocluster configuration study (Nanoscale, 2016, 8, 11454), we built the typically simplified Au13(Cys-Au-Cys) system to more clearly learn the basic modulation information of amino acid ligand on Au core by the density functional theory (DFT) calculations. There are two isomers as ligand adjacent bonding (Iso1) and diagonal bonding (Iso2) to Au13 cores. The geometry optimizations indicate the adjacent bonding Iso1 is more stable than Iso2. More important, the Au13 core of Iso1 distorts much more significantly than that of Iso2 by Cys-Au-Cys bonding through the root-mean-square deviation (RMSD) analysis, which modulate their electronic characteristics in different ways. In addition, the frontier molecular orbital results of Au13(Cys-Au-Cys) isomers confirm that the Au cores mainly determine the blue shifts of Au13(Cys-Au-Cys) systems versus the original Au13 core in their UV-visible absorption spectrum studies. The configuration of Au13 core performs deformation under Cys-Au-Cys ligand modulation to reach new stability with distinct atomic structure and electronic properties, which could be the theory basis for peptide coated AuNCs design and construction.

Este trabajo propone una lectura crítica de la novela escrita por mujeres a lo largo del siglo XIX, con el fin de releer la representación de la diferencia, es decir, del Otro femenino en la cultura anglosajona, así como sus ramificaciones críticas y culturales. Tomando como punto de partida el planteamiento crítico de Judith Halberstam sobre la mujer masculina (female masculine, el trabajo propone una revisión crítica de la novela escrita por mujeres en Inglaterra a lo largo del siglo XIX, entendiendo éste ideológicamente, el comprendido entre la Revolución Francesa y la Primera Guerra Mundial. La tesis fundamental que se explora en esta aportación se centra alrededor de la manera en que, por una parte, la mujer novelista supone una subversión del modelo de feminidad impuesto culturalmente a lo largo del siglo XIX.

  13. Fabricating a Homogeneously Alloyed AuAg Shell on Au Nanorods to Achieve Strong, Stable, and Tunable Surface Plasmon Resonances

    KAUST Repository

    Huang, Jianfeng

    2015-08-13

    Colloidal metal nanocrystals with strong, stable, and tunable localized surface plasmon resonances (SPRs) can be useful in a corrosive environment for many applications including field-enhanced spectroscopies, plasmon-mediated catalysis, etc. Here, a new synthetic strategy is reported that enables the epitaxial growth of a homogeneously alloyed AuAg shell on Au nanorod seeds, circumventing the phase segregation of Au and Ag encountered in conventional synthesis. The resulting core–shell structured bimetallic nanorods (AuNR@AuAg) have well-mixed Au and Ag atoms in their shell without discernible domains. This degree of mixing allows AuNR@AuAg to combine the high stability of Au with the superior plasmonic activity of Ag, thus outperforming seemingly similar nanostructures with monometallic shells (e.g., Ag-coated Au NRs (AuNR@Ag) and Au-coated Au NRs (AuNR@Au)). AuNR@AuAg is comparable to AuNR@Ag in plasmonic activity, but that it is markedly more stable toward oxidative treatment. Specifically, AuNR@AuAg and AuNR@Ag exhibit similarly strong signals in surface-enhanced Raman spectroscopy that are some 30-fold higher than that of AuNR@Au. When incubated with a H2O2 solution (0.5 m), the plasmonic activity of AuNR@Ag immediately and severely decayed, whereas AuNR@AuAg retained its activity intact. Moreover, the longitudinal SPR frequency of AuNR@AuAg can be tuned throughout the red wavelengths (≈620–690 nm) by controlling the thickness of the AuAg alloy shell. The synthetic strategy is versatile to fabricate AuAg alloyed shells on different shaped Au, with prospects for new possibilities in the synthesis and application of plasmonic nanocrystals.

    Full Text Available In this article, the authors study the decadence of wood piers along XIX century, mainly because of problems inherent to the attacks of invertebrates. Soon, the wood structures will be substituted by iron ones, appearing two extraordinary materials, cast iron and wrought iron. Cast iron was a material with a great compression resistance, but weak for traction and flexion. It was not welding, but its resistance to the corrosion was notable, because of it, was very used at piles of British sea piers. On the contrary, wrought iron offered high conditions for traction and flexion, so it appeared like a very useful material to make girders and joists, but suffering the problem of a lack of resistance to corrosion. The combination of both materials supposed a great success in the construction of bridges and piers, since 1850.

    Se estudia en el presente artículo cómo los embarcaderos de madera iban languideciendo a partir de mediados del siglo XIX, aquejados especialmente por los ataques de invertebrados. Pronto, en los embarcaderos británicos, la madera iba a ser sustituida por el hierro, en la versión de dos nuevos materiales, la fundición y el hierro forjado. La fundición poseía una gran resistencia a la compresión, aunque poca a la tracción y a la flexión. Tampoco permitía la soldabilidad, pero presentaba un comportamiento magnífico frente a la corrosión, siendo muy utilizada para pilares en los nuevos embarcaderos. El hierro forjado presentaba menor resistencia a la corrosión pero, en cambio, ofrecía altas prestaciones a tracción y flexión, lo que lo hacía muy valioso para su colocación en vigas y forjados en los muelles. De la combinación de ambos materiales resultó el gran éxito habido en la construcción de puentes y embarcaderos metálicos, a partir de 1850.

Corruption as a complex social phenomenon that occurs in the process of socio-economic, political and social relations has become one of the most pressing political, social and economic problems of modern Russia. The corruption in the state apparatus not only cause serious, sometimes unsolvable problems for the citizens, but also hinder the normal functioning of the administrative bodies and authorities. The legal component, the development and adoption of relevant laws perform a special role in combating corruption. For many centuries government has repeatedly attempted if not to eliminate or at least to curb corruption in numerous managerial and administrative apparatus. The greatest interest in this regard is the imperial period of Russian history.

    Full Text Available Las estructuras agrarias originadas en los procesos más generales de desarrollo capitalista y de redefinición de los derechos de propiedad del siglo XIX en la provincia argentina de Jujuy, resultaron favorables a la formación de importantes latifundios. La contracara de esa fuerte concentración de tierras fue la existencia de un amplio sector de la sociedad que compartía la condición de arrendatarios. De ahí que en este artículo nos proponemos estudiar a los arrendatarios como productores –la riqueza y los ingresos brutos procedentes de la explotación rural que tenían a su cargo– a fin de indagar su capacidad de remuneración, contrastándolos entre sí y con otras situaciones sociales. Para ello, analizamos dos casos que tratan el asunto de sus relaciones de producción en el arriendo. A partir de fuentes fiscales y censales de la década de 1890 que contienen datos de la actividad agropecuaria y de informes sobre la rentabilidad de los distintos productos de origen agrícola o ganaderos de la misma época, reconstruimos el ingreso bruto de esas unidades para cada uno de los actores involucrados en ellas y analizamos los niveles de desigualdad para ese conjunto social.

    Full Text Available Este artículo se propone volver la mirada hacia el origen del movimiento pentecostal chileno para sostener que este responde en su planteamiento sobre la modernidad a un evento de recomposición religiosa que no se encaminó hacia la privatización de la religión, sino a la conquista de los espacios públicos en un esfuerzo de resacralizarlos. El método de trabajo fue un análisis historiográfico, principalmente de fuentes hemerográficas y revisión de literatura sobre el pentecostalismo, que incorpora como lente de observación el enfoque de la secularización a fin de entender como los y las pentecostales interpretaron desde su experiencia religiosa el proceso de modernidad, en relación directa con el protestantismo misionero y el contacto con un catolicismo reformado tocado por los cambios finiseculares. Nuestro estudio nos permite sustentar que el pentecostalismo fue un fenómeno religioso que surge y se consolida en el proceso de modernidad latinoamericana, en ese contacto ha formulado su propuesta religiosa en medio de una trama compleja y cambiante respecto al papel que las instituciones y la sociedad han jugado desde el siglo XIX.

    Full Text Available In the 19th century, Mexican scientific research in physiology had two well defined periods and followed the same scientific ideas that dominated the rest of the world. In the first period that takes almost the whole century, physicians did experimental research at their own expenses. In the second period at the end of the century, President Pofirio Díaz's dictadure (1880-1910, pushed research on Physiology. This research was very nationalistic. Mexican physiological research at the 19th century was influenced by Celular Theory, Darwinism and Experimental Medicine.

    La investigación científica mexicana en fisiología tuvo dos períodos bien marcados en el siglo XIX y también siguió las corrientes que la modularon en el resto del mundo. En el primer período, médicos de manera individual y costeado por ellos mismos, hicieron trabajo experimental durante la mayor parte del siglo. En un segundo período, durante la dictadura de Porfirio Díaz (1880-1910, se crearon instituciones que con apoyo del gobierno propiciaron la labor científica en fisiología. Esta investigación tuvo un marcado tinte nacionalista y estuvo influenciada por la Teoría Celular, el Darwinismo y la Medicina Experimental.

    Full Text Available Las líneas que siguen tienen el propósito de examinar la visualización de un "sujeto" particular, el inmigrante, desde distintos ángulos: económico, político-jurídico y antropológico. El sujeto en cuestión, -el inmigrante-, se nos presenta en la segunda mitad del siglo XIX, bajo diversos rostros: o como simple unidad poblacional que puede incrementar cuantitativamente la variable demográfica, concebida ésta como puramente económica, o como variable cualitativa que involucra aspectos de carácter político, jurídico, antropológico y cultural que implican valoraciones. Nuestro análisis, quedará restringido al estudio de un corpus de fuentes bien delimitado: las tesis que los estudiantes de la Facultad de Derecho próximos a egresar debían presentarobligatoriamente para obtener el grado de Doctor en Jurisprudencia.

    Full Text Available El Panorama, una forma de arte de la revolución industrial, consistía en gigantescas pinturas circulares con una visión central de 360-, en las que se mezclaba arte y técnica. Estas pinturas circularon por las principales ciudades de Europa y América, París, Londres, Nueva York y atrajeron a un gran número de espectadores, lo que hizo posible el desarrollo del Panorama como una actividad empresarial. Al igual que otro fenómeno artístico marginal del siglo XIX, la revista ilustrada de actualidad, el Panorama debió su gran popularidad a una cultura visual de medio de masas, basada en un afán de saber y conocer, fruto de la filosofía positivista de la época.Panoramas were huge circular paintings with a 360- central view ttiat mixed art and tecfinique into an artistic form characteristic of the industrial revolution. These paintings traveled to the great european and American cities, París, London, New York, and attracted large crowds of spectactors, that allowed the Panorama to develop as a commercial activity. In a way similar to another marginal artistic manifestation of the 19th century, the illustrated magazine, the Panorama owed its popularity to a massmédium visual culture, that was based on a desire for knowledge, result of the positivist philosophy prevalent at the time.

    Full Text Available En la Nueva Granada hoy república de Colombia se habló por primera vez del autor inglés, Jeremías Bentham en 1811 cuando Antonio Nariño publicó en el periódico La Bagatela un artículo en donde se resaltaba su obra. Muchos personajes como Antonio Nariño, Simón Bolívar y Francisco de Paula Santander, utilizando su sistema epistolario, comentarios de otros autores y el análisis de textos, lograron conocer los planteamientos sobre la doctrina utilitarista, realizados por Jeremías Bentham y les pareció interesante y útil para los proyectos de la época, por lo cual lo incluyeron en la enseñanza de Legislación Civil y Penal de las Universidades y Colegios. Así, Bentham facilitó el proyecto educativo de Santander y en buena parte de los gobiernos radicales de Colombia de la segunda mitad del Siglo XIX, especialmente en lo relacionado con la instauración de la escuela laica.

    Full Text Available Since the Renaissance, the Tiber River has been the object of the most unusual archaeological quests, driven mainly by fantastic medieval lore. In the 18th and 19th centuries, the excavations on the river intensified and were epitomized by the scientific atmosphere of the Enlightenment, even tough they resulted in little archaeological worth. In 1819, even the Spanish monarch Fernando VII almost became a Shareholder in one of these archaeological companies. After the Italian unification, many finds were discovered in the works done along the Tiber's urban region, of wich many are now in the Museo Nazionale Romano.Desde el Renacimiento el Tiber ha sido objeto de las más peregrinas búsquedas arqueológicas, emprendidas habitualmente sobre la base de fantásticos relatos medievales. En los siglos XVIII y XIX las excavaciones en el río se intensificaron y se dotaron del cientificismo propio de la Ilustración, siendo no obstante el fruto de estos trabajos muy escaso; en 1819, incluso el propio monarca español Fernando VII estuvo a punto de convertirse en accionista de una de estas empresas arqueológicas. Tras la Unificación italiana, las obras de estructuración del curso urbano del Tiber propiciaron finalmente numerosos hallazgos, muchos de los cuales se conservan en el Museo Nazionale Romano.

El objetivo, analizar la fiesta pública del carnaval y sus relaciones con el poder decimonónico establecido en los puertos de Guaymas en el estado de So - nora y Mazatlán, en Sinaloa. El re sultado: esa fiesta caótica era correlativa a una sociedad igual - mente conf lictiva. El carnaval transgresivo se desarrolló cuando la élite económica y política de los dos puertos buscó posicionarse en los sucesivos gobiernos. Y al acentuarse durante el porfiriato una disparidad social que los afectaba también, no permanecieron como grupo aparte, sino diver - sificaron sus intereses económicos y culturales. Así, el carnaval, definido como metáfora de su tiempo, fue practicado por el pueblo y los notables, perpetuándose en las plazas públicas porteñas.

La participación de autoridades de gobierno, científicos, empresarios y trabajadores tuvo un claro propósito: diversificar las actividades productivas en respuesta a la debilidad del modelo económico y a las crisis cíclicas que se vivían por los altibajos en los precios del azúcar y el café en el mercado internacional. La experiencia exitosa del Perú con la explotación y comercialización del guano en los mercados europeos generó en Puerto Rico múltiples leyendas sobre el potencial económico de las islas de Mona y Monito, que en el mejor de los casos permanecería en el imaginario colectivo como una utopía en la búsqueda del desarrollo económico.

    Full Text Available El discurso de lo marginal, que el arte del siglo xix reclamaba como algo propio, encontró en la mujer un tópico social de especial significación para un siglo marcado por rápidas transformaciones. En apropiada correspondencia con su carácter de movimiento artístico marginal, la ilustración, y en particular la caricatura, iconografías populares cuyos códigos de representación eran simples y obvios, trataron muy especialmente aquellos tipos sociales que, por encontrase en proceso de evolución, resaltaban sobre el friso estático de la sociedad. La atención que prestaron las publicaciones ilustradas hacia los fenómenos marginales ha supuesto una ayuda notable para la historia social; tales publicaciones, aunque moderadas, disfrutaban de una difusión masiva, por lo que constituyeron una relevante fuerza ideológica y desempeñaron un importante papel en la formulación de una visión crítica.

Se plantea que esos lugares de la ciencia interesaron y fascinaron a expertos y profanos porque durante ese tiempo histórico lograron conciliar una triple función cognoscitiva y comunicativa: la de ser templos, laboratorios y teatros de la naturaleza. 1 Como depósito de las colecciones del mundo natural se convirtieron en un lugar de acumulación de tesoros y de adhesión a valores políticos y científicos. 2 Como ámbito de trabajo de los naturalistas que revelaban las claves del orden natural se transformaron en centros de investigaciones para ordenar y descifrar la naturaleza. 3 Como escenarios en los que se mostraban las maravillas de la naturaleza se autoconcibieron como una especie de gran teatro en el que se representaban lecciones de cosas del mundo natural a modo de un libro abierto.

Mientras para algunos fue un exponente de la llamada “Ilustración radical”, para otros se trató de uno de los primeros (si no del primer socialista moderno. Este trabajo propone que Babeuf fue una figura transicional, por lo cual tanto el “aspecto ilustrado” como el “socialista” estuvieron presentes. El caso de Louis Auguste Blanqui muestra cuán selectivas podían ser las recuperaciones de la experiencia babouvista y cuan complejo fue su legado. Abstract Gracchus Babeuf was a source of inspiration and a model for the revolutionaries to come. While for some authors he was an example of the so called “Radical Enlightenment”, for others he was among the first modern socialists, if not the first. This article proposes that this feudist lawyer was a transitional figure, in which both the “enlightened” and the “socialist” aspects were present. The case of Louis Auguste Blanqui illustrates how selective the recoveries of the babouvist experience could be and the complexities of his legacy.

    The interplay of nuclear effects on the p_T > 2 GeV inclusive hadron spectra in d+Au and Au+Au reactions at root(s) = 17, 200, 5500 GeV is compared to leading order perturbative QCD calculations for elementary p+p (p-bar+p) collisions. The competition between nuclear shadowing, Cronin effect, and jet energy loss due to medium-induced gluon radiation is predicted to lead to a striking energy dependence of the nuclear suppression/enhancement pattern in A+A reactions. We show that future d+Au data can used to disentangle the initial and final state effects.

    2003-01-15

    Near IR (NIR) sensitive Au-Au{sub 2}S nanocolloids were prepared by mixing HAuCl{sub 4} and Na{sub 2}S in aqueous solutions. An anti-tumor drug, cis-platin, was adsorbed onto Au-Au{sub 2}S nanoparticle surface via the 11-mercaptoundecanoic acid (MUA) layers. The results show that the degree of adsorption of cis-platin onto Au-Au{sub 2}S nanoparticles was controlled by the solution pH value, and the drug release was sensitive to near-infrared irradiation. The cis-platin-loaded Au-Au{sub 2}S nanocolloids can be potentially applied as NIR activated drug delivery carrier.

    We successfully prepared face-centred cubic nanoalloys in systems of Au-Ir, Au-Rh and Au-Ir-Rh, with large bulk miscibility gaps, in one-run reactions under thermal decomposition of specially synthesised single-source precursors, namely, [AuEn2][Ir(NO2)6], [AuEn2][Ir(NO2)6] х [Rh(NO2)6]1-х and [AuEn2][Rh(NO2)6]. The precursors employed contain all desired metals ‘mixed’ at the atomic level, thus providing significant advantages for obtaining alloys. The observations using high-resolution transmission electron microscopy show that the nanoalloy structures are composed of well-dispersed aggregates of crystalline domains with a mean size of 5 ± 3 nm. Еnergy dispersive x-ray spectroscopy and x-ray powder diffraction (XRD) measurements confirm the formation of AuIr, AuRh, AuIr0.75Rh0.25, AuIr0.50Rh0.50 and AuIr0.25Rh0.75 metastable solid solutions. In situ high-temperature synchrotron XRD (HTXRD) was used to study the formation mechanism of nanoalloys. The observed transformations are described by the ‘conversion chemistry’ mechanism characterised by the primary development of particles comprising atoms of only one type, followed by a chemical reaction resulting in the final formation of a nanoalloy. The obtained metastable nanoalloys exhibit essential thermal stability. Exposure to 180 °C for 30 h does not cause any dealloying process.

    2004-01-01

    The electronic properties of Au crystal and nano Au have been investigated by theory and experiment. Molecularly capped nano-Au was synthesized using the two-phase method. Au nano-particles have been characterized by X-Ray Diffraction (XRD) and Transmission Electron Microscopy (TEM). They retain the fcc crystal structure. Their sizes have been determined to be in a range from 5.5 nm to 1.7 nm. The L3 X-ray Absorption Near Edge Structure (XANES) of nano-Au and Au foil have been recorded using synchrotron radiation, and examined by theoretical calculation based on the first principles. Both theory and experiment show that the nano-Au particles have essentially all the Au L3 XANES features of bulk Au in the near edge region with less pronounced resonance peaks. It is also shown that nano Au exhibits lower 4f binding energy than bulk Au in good agreement with quantum confined Au systems reported previously.

  11. Stellar and Laboratory XUV/EUV Line Ratios in Fe XVIII and Fe XIX

    Science.gov (United States)

    Träbert, Elmar; Beiersdorfer, P.; Clementson, J.

    2011-09-01

    A so-called XUV excess has been suspected with the relative fluxes of Fe XVIII and Fe XIX lines in XUV and EUV spectra of the star Capella as observed by the Chandra spacecraft [1] when comparing the observations with simulations of stellar spectra based on APEC or FAC. We have addressed this problem by laboratory studies using the Livermore electron beam ion trap (EBIT). Our understanding of the EBIT spectrum is founded on work by Brown et al. [2]. The electron density of the electron beam in an EBIT is compatible to the density in energetic stellar flares. In our experiments, the relative detection efficiencies of two flat-field grating spectrographs operating in the EUV (near 100 Å) and XUV (near 16 Å) ranges have been determined using the calculated branching ratio of 1-3 and 2-3 transition in the H-like spectrum O VIII. FAC calculations assuming several electron beam energies and electron densities serve to correct the EBIT observations for the Maxwellian excitation in a natural plasma. In the EUV, the line intensity pattern predicted by FAC agrees reasonably well with the laboratory and Capella observations. In the XUV wavelength range, agreement of laboratory and astrophysical line intensities is patchy. The spectral simulation results from FAC are much closer to stellar and laboratory observation than those obtained by APEC.

  12. La reivindicación de un "diccionario gallego" en el siglo XIX

    2003-12-01

    Full Text Available In the vindication of a Galician dictionary in the second half of the 19th Century coalesced the main currents of the "Rexurdimento" movement initiated around 1850, in connection with the multiple interests to which this movement tried to respond. Only in the context of the "provincialist" and "regionalist" ideologies articulated by the Galician intelligentsia of the time is feasible to understand this demand for lexicographical compendia. The philological framing of a "Galician identity", and the recognition that publishing in Galician was the most unequivocal sign of its vitality, represent two key elements of the lexicographical movement that saw in the "Dictionary" an ideal instrument to secure the future of the Galician language and to legitimize a related collective identity.

    La elaboración y publicación de un diccionario de la lengua gallega en la segunda mitad del siglo XIX es una reivindicación en la que se dan cita, por los múltiples intereses que en ella convergen, los diferentes elementos que constituyen el horizonte ideológico del movimiento "rexurdimentista" iniciado en la década de 1850. Para entender este proceso de demanda lexicográfica, es inevitable enmarcarlo en el clima sociocultural "provincialista" y "regionalista" que experimenta la Galicia de la época. La articulación de una renovada "identidad gallega", traducida fundamentalmente en términos filológicos, y el reconocimiento de que la producción impresa en gallego era un signo inequívoco del grado de vitalidad de esta identidad, representan dos aspectos claves de este movimiento que veía en el "Diccionario" la condición de instrumento ideal para articular una conciencia colectiva y para salvaguardar la lengua que le servía de referente.

Com a Revolução Industrial, a migração de camponeses e as agitações políticas, em fins do século XVIII e inícios do XIX algumas dessas cidades, principalmente Londres e Paris, alçam-se à condição de metrópoles. Este artigo procura mostrar como em Paris _ a mais cosmopolita das cidades na época _ inauguram-se novos comportamentos, modas, modos e até mesmo uma nova gestualidade. Aponta também as representações que na literatura e nas ciências humanas se elaboram sobre esse novo modo de vida no qual certos vanguardistas de inícios deste século vislumbram a germinação de uma nova sensibilidade.In XVII and XVIIIth Century the capital cities of absolutist sovereignities are consolidated.

    Full Text Available Colombia se formó durante el siglo XIX. A partir de la destrucción dejada por las guerras de Independencia se afianzó la soberanía del Estado y se comenzó la construcción de una nación nueva. Partiendo de la democracia representativa se ensayaron diferentes formas políticas de gobierno, que muchas confrontaciones bélicas ocasionaron; se delimitó su territorio y se fijaron sus fronteras terrestres. Pero en medio del proceso se perdió la dimensión del mar. Un país otrora marinero con costas sobre los dos grandes océanos se territorializó, su dimensión mental del espació cambió; el mar ya no fue importante. Presidentes hubo que nunca salieron de la sabana de Bogotá y que paladinamente consideraron que para gobernar el país no hacía falta conocer el mar (me refiero a Miguel Antonio Caro y José Manuel Marroquín. La destrucción de Cartagena y su región fue, a no dudarlo, catalizador de este fenómeno, aunque pocos lo percibieron. La Plaza Fuerte se perdió en la reconquista y para rendirla hubo que destruir la economía de una comarca que abarca hoy cuatro departamentos. Poblaciones enteras fueron incendiadas hasta sus cimientos, Barranquilla una de ellas. El resto de la hoy región Caribe se desplomó con su centro de poder. Santa Marta se estancó y la pequeña Riohacha incendiada por mercenarios europeos quedó hecha pavesas hasta el punto de que el general Mariano Montilla tuvo que embarcar a sus pobladores en la flota que comandaban Brion y Padilla para evitar que murieran de hambre.

Los indígenas pertenecían a diversos grupos étnicos, como matlatzincas, otomíes, nahuas. Eran individuos que generalmente carecían de tierra propia. Los trabajadores de las haciendas recibieron diferentes denominaciones que se relacionaban con el cargo o actividad desempeñada. Estos aspectos les daban cierta jerarquía y a la vez dependencia.

  18. Parental Curse as Invisible Violence: Anti-maternity in the Traditional Culture of the XIX Century

    Directory of Open Access Journals (Sweden)

    Lidija Radulović

    2016-03-01

    Full Text Available Curse is an appellative genre, a clichéd verbal proverb that is uttered in belief, that with the assistance of supernatural forces, God or demon, through the magical properties of words, evil will come upon an individual. It is examined through the context of the ideal motherhood discourse in the tradition culture of the XIX and the first half of the XX century, in view that it was perceived to be an idiosyncrasy of female demeanor. Maternity as a cultural construct in the traditional culture of Serbia is based upon the ideal motherhood discourses as a gift from god, as an innate role for women, an inherent instinct for caring towards others, as an unconditional motherly love. In practice, normative regulations and the concrete actions of a mother are not in complete concurrence, mothers love is not an objective fact, it can be present or not, vary in intensity, it can be selective, but it will depend on the personal history and cultural construct. Through such a focal point, motherly curse is perceived as a form of behavior that can be signified as anti-maternity. In the conceptualization of a parental curse, from one viewpoint, the manner of usual behavior of women that has no real implications on the life of the child is legitimized, and on the other hand, it is believed that a mothers curse has the most potent magical effect and is delivered up to the ninth generation. Parental curse and the ritual of "cursing" do not include a black magic connotation, and were considered a legitimate social mechanism through which evil was countered with evil i.e. the transgressor was being punished in cases where there existed no formal mechanism of punishment. Through such actions, the community, or family are re-imposing order in the social relations, synchronously sending a message that reaffirms the correct matrix of behavior and moral values of the community.

  19. Iron marketing and modernisation in the Urals in XIX century: evident and implicit links

    2011-06-01

    Full Text Available Modernization theory, interpreted as a civilizational shift from traditional agrarian to a modern industrial society, allows considering innovations as the conditions necessary and sufficient for this transformation. Russia of the XIX century was characterized by similar processes. The transition to the new industrial technology foundation began decades before the abolition of serfdom. This paper tells about the experience of modernization of metallurgical production at Nizhny Tagil plants of Demidovs in 1840-1850. It is noted that export orientation of iron and steel in Western Europe played a powerful incentive to improve the technical and technological base of the mountain plants of the Middle Urals. Also important is the fact that the Demidovs administration has sought means to minimize the number of intermediaries in the sale of their products. The administration has sought ways to help commissioners get responses back from direct consumers of iron produced in Nizhny Tagil plants. Demidovs were interested, as they assessed the quality of the metal, which "internal properties" they would like to see in their iron in order to successfully use it in the production process. In turn, the domestic market was practicing somewhat different approach to trading metals - a network of regional sales offices in most major economic centers was functioning to better know the requirements for the quality of the metal and the volume of its production plan in line with the real needs of specific types of iron and copper. At the same time, the contradictory nature of the modernization process itself, in particular, the reluctance of the management of enterprises pass on the use of coal as a primary fuel source is highlighted. In fact, the use of coal Nizhny Tagil plants began to implement only in 1880, which did not stop Demidovs during the post-reform period to increase volumes of metal smelting on the old industrial-energy base.

    Full Text Available L’olivier est une culture traditionnelle sur le pourtour de la Méditerranée. Il est donc naturel de trouver cet arbre au Maroc où il est présent depuis des siècles. Cultivé surtout traditionnellement jusqu’à ses dernières années, il fait l’objet maintenant d’un plan de valorisation très ambitieux pour non seulement garder le Royaume à son niveau actuel (2e producteur mondial pour l’olive de conserve et 6e pour l’huile d’olive mais pour conquérir de nouveaux marchés au niveau mondial et profiter ainsi de l’engouement que connaît cette huile reconnue pour ses bienfaits. Le plan national « Maroc Vert » permet ainsi, grâce à des subventions conséquentes, non seulement de renouveler les vergers existant avec la variété traditionnelle picholine du Maroc, mais également la plantation de nouvelles variétés en super-intensif dans le but d’industrialiser au maximum de nouveaux vergers. Il en est de même pour la transformation des olives en huile de bonne qualité avec la mise en place d’unités de trituration modernes qui doivent supplanter à terme la multitude de « maâsra » et réduire ainsi l’impact environnemental dû aux margines. L’olive ne sera plus dans l’avenir que représentée par son huile et ses formes comestibles, mais les résidus de son extraction seront valorisés soit sous forme de combustible élaboré pour le grignon, soit sous forme d’une base de chimie verte pour les sous-produits du raffinage. D’autres applications sont actuellement à l’étude, car le Maroc à compris, comme tous les autres grands pays producteurs, que l’olive était un nouveau gisement de richesses.

Para realizar a pesquisa foram revistas 83 teses médicas obstétricas - produzidas tanto na Bahia quanto no Rio de Janeiro - no século XIX. Verificou-se que, tradicionalmente, esta Arte era realizada por mulheres denominadas "aparadeiras" ou "comadres", que assistiam as mulheres, seja no trabalho de parto e nos cuidados pré e pós-parto, quanto em outras circunstâncias, tais como doenças venéreas e abortos. A entrada dos médicos-parteiros nesta prática inaugurou, não só o esquadrinhamento do corpo feminino, como a produção de um saber anatômico e fisiológico da mulher, a partir do olhar masculino.This research aimed at recovering the peculiarities of the development of Obstetrical Art in Brazil during XIX century, starting in 1808, when a legal act signed by D. João VI included this discipline in the initial curriculum of the schools of medicine and surgery founded in Bahia and Rio de Janeiro. Research was undertaken through the review of 83 medical theses in the field of Obstetrics, produced in Bahia and Rio de Janeiro in XIX century. The data showed that Obstetrical Art was traditionally performed by women called "aparadeiras" (catchers or "comadres", who cared for women before, during and after delivery, and provided assistance in other situations, like venereal diseases and abortion. The inclusion of physicians-obstetricians in this practice led not only to a scrutinizing of the female body, but also to the production of an anatomical and physiological knowledge of the female organism from a male standpoint.

    Full Text Available Chemically pure colloidal suspensions of gold and silver nanoparticles were synthesized using pulsed laser ablation. The dependence of laser fluence on the surface plasmon characteristics of the nanoparticles was investigated. Au:Ag colloidal suspensions were prepared by mixing highly monodisperse Au and Ag nanocolloids. The plasmon band of these mixtures was found to be highly sensitive to Au:Ag concentration ratio and wavelength of the laser beam used in the ablation process. The Au:Ag mixture consists of almost spherical shaped nanostructures with a tendency to join with adjacent ones. The surface enhanced Raman scattering activity of the Au, Ag and Au:Ag colloidal suspensions was tested using crystal violet as probe molecules. Enhancement in Raman signal obtained with Au:Ag substrates was found to be promising and strongly depends on its plasmon characteristics.

    Full Text Available Parmi les multiples outils de “civilisation” à la portée des dirigeants latino-américains du siècle dernier, l’immigration européenne s’imposa évidemment comme un des plus attirants, de par son caractère concret : au lieu d’importer des normes, il s’agissait d’importer des hommes “civilisés”, en chair et en os. Dans la course à l’immigration, qui caractérise la culture politique du XIXe siècle latino-américain, la Colombie se distingue par son incapacité à réaliser ce rêve. Malgré les échecs répétés des tentatives officielles, les groupes dirigeants débattent, tout au long du siècle des bienfaits et des dangers de l’immigration les plans d’immigration mis en oeuvre par les différentes tendances politiques qui se succèdent au pouvoir cristallisent leurs projets idéologiques. Les projets immigrationnistes, tout autant qu’ils révèlent les fluctuations de la perception de l’Europe, reflètent à merveille les différentes versions de l’idéal “civilisateur” des élites colombiennes. Mais l’absence de dynamique interne, l’inexistence d’un réel besoin de main-d’oeuvre, la fragilité des circuits étatiques, qui s’ajoutent aux obstacles évidents du pays - faible niveau d’activité économique, insuffisante intégration au marché international, difficulté de lutter contre la concurrence de pays plus prometteurs comme les États-Unis ou l’Argentine - achèveront d’enterrer l’idéal d’une immigration “civilisatrice”.

    Full Text Available In the article on the memoirs and archival material basis of Central State Historical Archives of Ukraine, Kyiv and State Archives of Kharkiv Region the etymology of some actor’s pseudonyms on the Dnieper Ukraine territory in late XIX – early XX century was analysed. The pseudonyms’ place and role in desired professional actor image formation were determined. In particular the fact that pseudonyms borrowed or transformed from the famous literary character names used to transfer the character’s moral qualities and exterior to the artist was defined. The stage name creation specificity depending on the affiliation of the actor to the Russian or Ukrainian repertoire was shown. Also the basic motives for fictional anthroponym using in actors’ society were depicted. The main reason for the actor’s name-change among ones originated from the nobility and clergy was shown. Besides the recognition of pseudonym as the important part of professional success not only among the actors, but also among entrepreneurs of Dnieper Ukraine in late XIX – early XX century was explored.

  10. Controlled Synthesis of Au@AgAu Yolk-Shell Cuboctahedra with Well-Defined Facets.

    2016-08-02

    The synthesis of Au@AgAu yolk-shell cuboctahedra nanoparticles formed by galvanic replacement in a seed-mediated method is described. Initially, single-crystal Au seeds are used for the formation of Au@Ag core-shell nanocubes, which serve as the template material for the deposition of an external Au layer. The well-controlled synthesis yields the formation of cuboctahedra nanoparticles with smooth inner and outer Au/Ag surfaces. The deposition/oxidation process is described to understand the formation of cuboctahedra and octahedra nanoparticles. The Au core maintains the initial morphology of the seed and remains static at the center of the yolk-shell because of residual Ag. Structural analysis of the shell indicates intrinsic stacking faults (SFs) near the surface. Energy dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) compositional analysis show an Au-Ag nonordered alloy forming the shell. The three-dimensional structure of the nanoparticles presented open facets on the [111] as observed by electron tomography SIRT reconstruction over a stack of high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) images. The geometrical model was validated by analyzing the direction of streaks in coherent nanobeam diffraction (NBD). The catalytic activity was evaluated using a model reaction based on the reduction of 4-nitrophenol (4-NTP) by NaBH4 in the presence of Au@AgAu yolk-shell nanoparticles.

Resulta una nueva aportación puesto que, sobre este tema concreto, no existe ninguna bibliografía. Para llevarlo a cabo, se ha comenzado por intentar aclarar el panorama confuso de las clasificaciones tipográficas. Basándonos en la clasificación Vox -aceptada internacionalmente- se han diferenciado, uno por uno y de forma cronológica, el tipo de caracteres empleados en la cartelería taurina decimonónica. También se han investigado los modelos estéticos, los intercambios entre imprentas, la perduración de diferentes estilos en el tiempo, el concepto tan peculiar de «legibilidad» del cartel, la relación con el libro y otros impresos, el diseño de letras manuales... en fin, la estrategia de la comunicación, el atractivo de la representación y el inmovilismo, frente a la originalidad y la renovación.This article addresses -for the first time the study of graphic tipology represented in the bullfight affiche of the 19th century.

Following the internationally accepted Vox classification, the goal of the study has been to differenciate one by one, each typographic character in the tauromachy poster of the 19th century. In addittion, this is an overview ofthe aesthetic patterns, the exchanges among printers, the persistency of certain styles throughout time, the alway peculiar concept of «legibility» in a poster, the relationships between a poster and other books and printed material, the design of the handwritten letters... and ultimately, the communication strategy, the appeal of representation and the dynamics between inmovilist attitudes and original and innovative ones.

    This volume contains the lectures and short talks given at the XIX International School on Nuclear Physics, Neutron Physics and Applications. The School was held from 19-25 September 2011 in 'Club Hotel Bolero' located in the 'Golden Sands' (Zlatni Pyasaci) Resort Complex on the Black Sea coast, near Varna, Bulgaria. The School was organized by the Institute for Nuclear Research and Nuclear Energy of the Bulgarian Academy of Sciences. The co-organizer of the School was the Bulgarian Nuclear Regulatory Agency and the Bogoliubov Laboratory of Theoretical Physics of the Joint Institute for Nuclear Research - Dubna. According to long-standing tradition the School has been held every second year since 1973. The School's program has been restructured according to our enlarged new international links and today it is more similar to an international conference than to a classical nuclear physics school. This new image attracts many young scientists and students from around the world. This year - 2011, we had the pleasure of welcoming more than 50 distinguished scientists as lecturers. Additionally, 14 young colleagues received the opportunity to each present a short contribution. The program ranged from recent achievements in areas such as nuclear structure and reactions to the hot topics of the application of nuclear methods, reactor physics and nuclear safety. The 94 participants enjoyed the scientific presentations and discussions as well as the relaxing atmosphere at the beach and during the pleasant evenings. The main topics were as follows: Nuclear excitations at various energies Nuclei at high angular moments and temperature Structure and reactions far from stability Symmetries and collective phenomena Methods for lifetime measurements Astrophysical aspects of nuclear structure Neutron nuclear physics Nuclear data Advanced methods in nuclear waste treatment Nuclear methods for applications Several colleagues helped with the organization of the School.

  14. Synthesis of ultrathin face-centered-cubic Au@Pt and Au@Pd core-shell nanoplates from hexagonal-close-packed Au square sheets

    KAUST Repository

    2015-03-17

    The synthesis of ultrathin face-centered-cubic (fcc) Au@Pt rhombic nanoplates is reported through the epitaxial growth of Pt on hexagonal-close-packed (hcp) Au square sheets (AuSSs). The Pt-layer growth results in a hcp-to-fcc phase transformation of the AuSSs under ambient conditions. Interestingly, the obtained fcc Au@Pt rhombic nanoplates demonstrate a unique (101)f orientation with the same atomic arrangement extending from the Au core to the Pt shell. Importantly, this method can be extended to the epitaxial growth of Pd on hcp AuSSs, resulting in the unprecedented formation of fcc Au@Pd rhombic nanoplates with (101)f orientation. Additionally, a small amount of fcc (100)f-oriented Au@Pt and Au@Pd square nanoplates are obtained with the Au@Pt and Au@Pd rhombic nanoplates, respectively. We believe that these findings will shed new light on the synthesis of novel noble bimetallic nanostructures. Phase change: Ultrathin Au@Pt and Au@Pd core-shell nanoplates were prepared from Au square sheets. A phase transformation from hexagonal close-packed (hcp) to face-centered cubic (fcc) is observed upon coating the hcp Au square sheets with Pt or Pd under ambient conditions. The prepared fcc Au@Pt and Au@Pd rhombic nanoplates demonstrate unique (101)f orientation (picture shows a typical fcc Au@Pt rhombic nanoplate). © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    X-ray-absorption fine structure (XAFS) and x-ray-diffraction (XRD) measurements of disordered alloys Au x Cu 1-x and Au 0.5 Ag 0.5 prepared by melt spinning were performed. In the Au 0.5 Ag 0.5 alloy, no significant local deviations of the atoms from the average fcc lattice were detected while in Au x Cu 1-x alloys, significant deviations of atoms from the average fcc lattice were found. Mean-square vibrations of the Cu-Cu distances revealed by the XAFS in Au x Cu 1-x alloys indicate the weakening of contact between Cu atoms in the dilute limit. Our computer simulation for Au x Cu 1-x clusters of 10 5 atoms reproduces the main features of both the XAFS and XRD data

    We present transverse momentum distributions of charged hadrons produced in Au+Au collisions at sqrt(s_NN) = 200 GeV. The evolution of the spectra for transverse momenta p_T from 0.25 to 5GeV/c is studied as a function of collision centrality over a range from 65 to 344 participating nucleons. We find a significant change of the spectral shape between proton-antiproton and peripheral Au+Au collisions. Comparing peripheral to central Au+Au collisions, we find that the yields at the highest p_T exhibit approximate scaling with the number of participating nucleons, rather than scaling with the number of binary collisions.

    Three Au-based nanomaterials (silica-Au nanoshells, hollow Au/Ag nanospheres and Au nanorods) were evaluated for their comparative photothermal efficiencies at killing three types of malignant cells (A549 lung cancer cells, HeLa cervix cancer cells and TCC bladder cancer cells) using a CW NIR laser. Photodestructive efficiency was evaluated as a function of the number of nanoparticles required to destroy the cancer cells under 808 nm laser wavelength at fixed laser power. Of the three nanomaterials, silica/Au nanoshells needed the minimum number of particles to produce effective photodestruction, whereas Au nanorods needed the largest number of particles. Together with the calculated photothermal conversion efficiency, the photothermal efficiency rankings are silica-Au nanoshells > hollow Au/Ag nanospheres > Au nanorods. Additionally, we found that HeLa cells seem to present better heat tolerance than the other two cancer cell lines.

    Ligand-protected Au clusters are non-bleaching fluorescence markers in bio- and medical applications. We show that their fluorescence is an intrinsic property of the Au cluster itself. We find a very intense and sharp fluorescence peak located at λ =739.2 nm (1.68 eV) for Au20 clusters in a Ne matrix held at 6 K. The fluorescence reflects the HOMO-LUMO diabatic bandgap of the cluster. The cluster shows a very rich absorption fine structure reminiscent of well defined molecule-like quantum levels. These levels are resolved since Au20 has only one stable isomer (tetrahedral), therefore our sample is mono-disperse in cluster size and conformation. Density-functional theory (DFT) and time-dependent DFT calculations clarify the nature of optical absorptionand predict both main absorption peaks and intrinsic fluorescence in good agreement with experiment.

    Smith, E.J.

    1985-01-01

    Attention is given to spatial dependences exhibited by spacecraft measurements obtained between 1 and 30 AU, together with temporal variations occurring between solar activity cycle maxima and minima. At 1-3 AU radial distances, shocks develop in association with the corotating solar wind streams characterizing solar minimum and accelerate solar wind evolution with distance while heating the solar wind and generating waves and turbulence. At solar maximum, shocks are observed more frequently at 1 AU but still in association with transient solar events; acceleration leading to energetic storm particles is observed both within and beyond 1 AU. The superimposed effect of large numbers of intense shocks may be responsible for the solar cycle modulation of galactic cosmic rays. 77 references

    The electronic energy loss for low velocity protons channeled in the direction single crystal Au is calculated. The spatial distribution of valence electronic density in Au is calculated using Tight Binding Linear Muffin Tin Method. The proton trajectories are determined by numerical integration of the classical motion equation, and the energy loss is evaluated using the calculated valence electronic density in the friction term. The results allow to describe qualitatively the non linear behavior of energy loss with ion velocity observed experimentally. (author)

    Asymmetric nanocrystals have practical significance in nanotechnologies but present fundamental synthetic challenges. Thiol ligands have proven effective in breaking the symmetric growth of metallic nanocrystals but their exact roles in the synthesis remain elusive. Here, we synthesized an unprecedented Au nanorod-Au nanoparticle (AuNR-AuNP) dimer structure with the assistance of a thiol ligand. On the basis of our experimental observations, we unraveled for the first time that the thiol could cause an inhomogeneous distribution of surface strains on the seed crystals as well as a modulated reduction rate of metal precursors, which jointly induced the asymmetric growth of monometallic dimers. © 2015 American Chemical Society.

These measurements suggest a large energy loss of the high-pT particles in the highly interacting medium created in the central Au + Au collisions. The lack of suppression in d + Au collisions suggests that it is unlikely that initial state effects can explain the suppression in the central Au + Au collisions. PACS: 25.75.-q

    The proton beam intensity of a 100-MeV proton linac at the Korea Multi-purpose Accelerator Complex (KOMAC) was measured by an Au activation analysis using {sup 197}Au(p, pn){sup 196}Au and {sup 197}Au(p, p3n){sup 194}Au reactions to determine the accuracy and precision of beam intensity measurement using Gafchromic film dosimetry method. The target, irradiated by 100-MeV protons, was arranged in a stack consisting of Au, Al foils and Pb plates. The yields of produced radio-nuclei in Au foils were obtained by gamma-ray spectroscopy. The FLUKA code was employed to calculate the energy spectrum of protons onto the front surface of Au foils located at three different depth points of the target and also to investigate the condition of incident beam on the target. A good agreement was found between the beam intensity measurements using the activation analysis method at three different depth points of the target. An excellent agreement was also observed between the beam intensity measurements using the Au activation analysis method and the dosimetry method using Gafchromic film.

The Conference was devoted to the discussion of the most recent experimental and theoretical achievements in the field of Nuclear Physics applications, as well as of the latest developments in technological tools related to Nuclear Physics research. The University of Pavia has a long tradition in Physics and in Applied Physics, being the site where Alessandro Volta developed his "pila", the precursor of the modern battery. This is the place where the first experiments with electricity were conducted and where the term "capacitance" used for capacitors was invented. Today the University hosts a Triga Mark II nuclear reactor, which is used by the Departments of the University of Pavia and by other Universities and private companies as well. Moreover, Pavia is the site selected for the construction of the CNAO complex "Centro Nazionale di Adroterapia Oncologica" (National Centre for Oncological Hadrontherapy), planned for 2005-2008 which represents a unique facility in Italy and will be among the first complexes of this type in Europe. The Conference has gathered together experts in various fields from different countries and has been the occasion to review the present status and to discuss the new emerging trends in Nuclear Physics and its applications to multidisciplinary researches and the development of new technologies. The following topics were treated: Nuclear Techniques in Medicine and Life Sciences (Cancer Therapy, new Imaging and Diagnostics Tools, Radioisotope production, Radiation Protection and Dosimetry). Applications of Nuclear Techniques in Art, Archaeometry and other Interdisciplinary fields

    Full Text Available Catalytic activity of nano-Au-catalyst(s for the complete propane oxidation was investigated. The results showed that the nature of both Au precursor and support strongly influences catalytic activity of the Au-catalyst(s for the propane oxidation. Oxidation state, size, and dispersion of Au nanoparticles in the Au-catalysts, surface area, crystallinity, phase structure, and redox property of the support are the key aspects for the complete propane oxidation. Among the studied Au-catalysts, the AuHAuCl4-Ce catalyst is found to be the most active catalyst.

    Being able to precisely control the morphologies of noble metallic nanostructures is of essential significance for promoting the surface-enhanced Raman scattering (SERS) effect. Herein, we demonstrate an overgrowth strategy for synthesizing Au @ M (M = Au, Ag, Pd, Pt) core-shell heterogeneous nanocrystals with an orientated structural evolution and highly improved properties by using Au nanorods as seeds. With the same reaction condition system applied, we obtain four well-designed heterostructures with diverse shapes, including Au concave nanocuboids (Au CNs), Au @ Ag crystalizing face central cube nanopeanuts, Au @ Pd porous nanocuboids and Au @ Pt nanotrepangs. Subsequently, the exact overgrowth mechanism of the above heterostructural building blocks is further analysed via the systematic optimiziation of a series of fabrications. Remarkably, the well-defined Au CNs and Au @ Ag nanopeanuts both exhibit highly promoted SERS activity. We expect to be able to supply a facile strategy for the fabrication of multimetallic heterogeneous nanostructures, exploring the high SERS effect and catalytic activities.

    In connection to the decision of installing the INDRA detector by the SIS synchrocyclotron at GSI (Darmstadt, Germany) the report presents the tasks taken into account by the LPC-Caen. These refer to the detector displacement and (mechanical) installation at GSI, the tests before beam (i.e. electronics acquisition software, detectors, etc.) as well as the data acquisition and processing. The physical pro-arguments mention the possibility of disposing of heavy ion beams in a range from 50 MeV to several GeV/nucleon so extending the study of multifragmentation done at GANIL between 30 and 90 MeV/nucleon. More specific, the scientific program of INDRA at GSI inserts studies between those done at around Fermi energy, were the reaction mechanisms are of type of deep inelastic scattering/incomplete fusion, and the studies in the relativistic energy domain where the individual properties of nucleons and transparency of nuclear matter implies mechanisms of the participant-spectator type (fire-ball creation). Also mentioned as fields of extensive studies are: the multifragmentation and its fundamental relation with the nuclear matter equation of state, the role of reaction dynamics in the appearance of collective effects of the radial flow type and its relations with the nuclear compressibility and phase transitions and the thermodynamics of nuclear matter. It appeared that the heavy systems Xe + Sn and Au + Au are the best compromise for the different topics to be approached. The bombarding energies extend from 50 to 150 MeV/nucleon. The report ends with the table giving for six heavy systems (Xe + Sn, Au + Au, C + Au, Ar + Au and P + Au) the required bombarding energies 15 refs.

    Full Text Available En este artículo se sugiere que para discutir los valores del patrimonio moderno –en términos de arquitectura y urbanismo–, es necesario revisar lo sucedido con la fundación de ciudades en el siglo xix. Se describen las raíces de la planificación moderna tanto a partir de diversos tipos de proyectos para el establecimiento de poblados, como de ejemplos de “colonias militares y civiles”, con énfasis en el norte de México. Se explica por qué no es posible despreciar dichas realizaciones, sólo por ser de escala pequeña, pues fueron parte de la reflexión, ilustrada y decimonónica sobre el ordenamiento del territorio y la ciudad moderna.

Acredita-se que a reflexão sobre as inúmeras teorizações é de grande importância na medida em que somente ela pode revelar os percalços e os caminhos inusitados que a democracia percorreu e continua a percorrer. A construção de inúmeros significados para a democracia dialoga, de alguma forma, com as diversas indagações que .se desenvolveram no transcorrer dos tempos. A constante reelaboração destes significados não se da num vazio, uma vez que ela recorre permanentemente a uma enorme herança teórica que tem se formado no transcorrer dos séculos.

    2001-01-01

    Full Text Available El periodismo especializado en ciencia y tecnología en España no ha alcanzado los niveles de los países anglosajones. Ello se pone de manifiesto no sólo por la relativa ausencia de suplementos destinados a ciencia en los periódicos generalistas sino, sobre todo, por la ausencia de portales de Internet en los que se divulgue la ciencia en español así como los logros en este campo de la comunidad hispana. Pero esta circunstancia no es casual: es el producto de una historia, la de la ciencia en España, que siempre ha tenido muchos detractores, entre ellos la iglesia. En este artículo se analiza cómo influyó la historia de España desde el siglo XII hasta principios del XIX en el actual periodismo especializado en ciencia.

    Full Text Available The explosive development of Cuba´s sugar industry in the 1 st half of the 19th century had a profound effect on the environment. First among the white creoles' concerns was the rapid deforestation. Many of them, however, also objected to the industry's growth on the grounds that it was causing a substantial increase of the black population on the island.

    El gran desarrollo de la industria azucarera en Cuba en la primera mitad del siglo XIX influyó de forma decisiva en el medio ambiente. La demanda acuciante de madera y de mano de obra esclava para los ingenios pasaron a ser el tema de preocupación entre algunos criollos de la élite. Ambos problemas aparecen unidos en sus peticiones para frenar la deforestación.

    Full Text Available Fly puparia and adult fragments of diptera muscid were found inside the esophagus of a mummified body from the early XIX century, buried inside the crypt of the Sacrament Church (Lisbon, Portugal. The identification of the material revealed a monospecific colonization by Ophyra capensis (Wiedemann (Diptera: Muscidae, a species known to invade corpses in the ammoniacal fermentation wave. This species can be found in corpses kept indoors, not available to the early waves of blowflies (Diptera: Calliphoridae. In the present case, the number of pupae and their developmental stage suggest that the female invaded the mummified corpse through the partially opened mouth and the oviposition took place directly inside the esophagus. This is the first case of O. capensis infesting internal organs of an intact corpse. The use of chemical products for the embalming process probably explains why external colonization did not occur.

    An overview is given of the principal lines of research into Physics during the end of the nineteenth century. At that time, a long series of successful theories which appeared to be final and conclusive had strengthened a conservative epistemological dogma which held that in the future research would consist merely of ever-more precise measurements, in the absence of any revolutionary innovations. However, it turned out that Nature was to reveal some of her mysterious and unexpected secrets to certain bright minds working in laboratories. (author) [Spanish] Se presentan las principales lineas de investigacion en Fisica en las ultimas decadas del siglo XIX. Una larga serie de exitosas teorias aparentemente finales y conclusivas habian fortalecido por entonces un dogma epistemologico conservador que presagiaba solo se continuaria acumulando mediciones mas y mas precisas sin innovaciones revolucionarias. La naturaleza reservaba sin embargo revelar en los laboratorios, a las mentes agiles, algunos de sus misteriosos e insospechados secretos. (autor)

    The cyanidation process has been used commercially for the past 100 years, there are ores that are not amenable to treatment by cyanide. Interest in alternative lixiviants, such as thiourea, halogens, thiosulfate and malononitrile, has been revived as a result of a major increase in gold price, which has stimulated new developments in extraction technology, combined with environmental concern. The Au extraction process using the thiourea solvent has many advantages over the cyanidation process, including higher leaching rates, faster extraction time and less than toxicity. The purpose of this study was investigated to the extraction characteristic of Au-Ag from two different Au concentrate (sulfuric acid washing and roasting) under various experiment conditions (thiourea concentration, pH of solvent, temperature) by thiourea solvent. The result of extraction experiment showed that the Au-Ag extraction was a fast extraction process, reaching equilibrium (maximum extraction rate) within 30 min. The Au-Ag extraction rate was higher in the roasted concentrate than in the sulfuric acid washing. The higher the Au-Ag extraction rate (Au - 70.87%, Ag - 98.12%) from roasted concentrate was found when the more concentration of thiourea increased, pH decreased and extraction temperature increased. This study informs extraction method basic knowledge when thiourea was a possibility to eco-/economic resources of Au-Ag utilization studies including the hydrometallurgy.

    Highlights: • An inversed Au/ZnO nanostructure was fabricated with ZnO loaded onto Au. • The Au/ZnO nanocomposites showed enhanced properties in visible-light photocatalysis. • The SPR effect of Au was considered important for visible-light photocatalysis. - Abstract: In this paper, we fabricate Au/ZnO nanostructure with smaller ZnO nanoparticles loaded onto bigger gold nanoparticles via combining seed-mediated method and sol-gel method. The obtained Au/ZnO nanocomposites exhibit excellent properties in photocatalysis process like methyl orange (MO) degradation and oxidative conversion of methanol into formaldehyde under visible light irradiation. The enhanced properties were ascribed to the surface plasmon resonance (SPR) effect of Au nanoparticles, which could contribute to the separation of photo-excited electrons and holes and facilitate the process of absorbing visible light. This paper contributes to the emergence of multi-functional nanocomposites with possible applications in visible-light driven photocatalysts and makes the Au/ZnO photocatalyst an exceptional choice for practical applications such as environmental purification of organic pollutants in aqueous solution and the synthesis of fine chemicals and intermediates.

    Full Text Available Este artículo pone de manifiesto el contexto en el cual las mujeres chilenas de las aldeas del siglo XIX son víctimas de diversos tipos de agresiones físicas, directas e indirectas, y psicológicas. Las conductas violentas de los agresores son explicadas en el marco de una comunidad que las reconoce como un componente habitual de la vida cotidiana. Así, se delimitan espacios específicos en los que se desenvuelven las relaciones de la gente, tales como el mundo urbano de la aldea y el mundo doméstico de la casa. En ambos, las personas construyen redes colectivas de solidaridad y fraternidad; pero, al mismo tiempo, desarrollan relaciones de competencia que son generadoras de roces y agresiones que ilustran la sociabilidad y el parentesco. Por otra parte, las mujeres agredidas confundieron a menudo la agresión con la aceptación de la autoridad masculina que permitía suponer la existencia de un matrimonio socialmente aceptado y cotidianamente bien llevado. La actitud de rebeldía femenina chocaba con el rechazo social y el ejercicio de un poder marital que se expresaba en conductas agresivas. Así, las relaciones en la pareja no fueron entre iguales, sino jerárquicas, imponiendo a las mujeres un rol subordinado y dependiente frente a los hombres, los que, a su vez, ostentaban la autoridad suficiente para controlarlas y castigarlas. Con la ayuda documental de un abundante número de expedientes judiciales se intenta comprender y explicar las conductas que asumen hombres y mujeres en la relación familiar desarrollada en las aldeas chilenas del siglo XIX.

    From May 25 to 30, 2003 the beautiful city of Cancun, located in the heart of the ancient Maya Empire in Mexico, hosted the XIX ALASBIMN CONGRESS. More than 300 attendees and 80 lecturers from the American continent and Europe had the opportunity to share their knowledge and enjoy an outstanding scientific, cultural and social program. The Scientific program included reviews and original scientific papers on basic and clinical sciences as well as on new developments in diagnostic and therapeutic nuclear medicine. Cardio-vascular, neuropsychiatric, oncology, skeletal and paediatric procedures were comprehensively analysed by several experts. Introduction of new cyclotrons and modern PET and PET/CT systems in Latin America has opened new horizons for the nuclear medicine community in this sub-continent. New radiopharmaceuticals based on different peptides, receptors and gene expression dominated the scene. Reporter gene imaging of gene expression has become the first and best example of what is achievable by modern molecular imaging. Of particular interest was the presentation of novel and potential agents for radio-metabolic therapy. Additionally, in connection with the congress the IAEA organised a very successful Regional Training Course on Paediatric Nuclear Medicine with 23 participants from 11 countries. The Agency also hosted the first national project coordinators meeting of the IAEA Regional Project aimed at establishing a regional tele-nuclear medicine network in the Latin American Region in conjunction with the ALASBIMN meeting. Once again the major companies representing the nuclear medicine industry participated in the Congress and contributed to the success of the ALASBIMN meeting. In summary, attending the XIX ALASBIMN meeting was a very rewarding experience in every aspect. We are most grateful to the organisers for hosting such a nice congress. Congratulations! Now we are looking forward to participate in the next ALASBIMN Congress to be held in the

    Full Text Available La larga tradición anglosajona de crónicas de viaje, junto a los avances en prensa y comunicaciones, propiciaron la aparición de una cierta imagen de la mujer española en publicaciones gráficas de la segunda mitad del siglo XIX. La nostalgia romántica de los artistas del xix por una España rica en huellas del pasado resultó en una visión de la española cargada de pintoresquismo y crítica a su retraso social. Los tópicos de esa visión se escenificaron en la prensa ilustrada siguiendo variantes estéticas de la época: la variante positivista de la viñeta tipológica: la literario-costumbrista de los relatos y guias de viaje; la periodística del dibujo de noticia.The old English tradition of travel chronicles, together with press and communication advances, gave rise to a particular image of Spanish women in British and American magazines of the second half of the nineteenth century. The artist's Romantic longing for the legacy of Old Spain resulted in both a picturesque view of her women and criticism of their backward social condition. The graphic press set down a variety of images of Spanish women following aesthetic trends of the times: the positivist approach in typological vignettes; high-art images from touristic literature; a journalist's view in news illustrations.

    Full Text Available Synthesis of metal-semiconductor heterostructures may allow the combination of function of the corresponding components and/or the enhanced performance resulting from the interactions between all the components. In this paper, Au@Cu2O core-shell heterostructures are prepared by a seed-growth method, using different-shaped Au nanocrystals as the seeds such as nanorods, octahedra, decahedra, dots, and nanocubes. The results revealed that the final structure of Au@Cu2O was greatly influenced by the shape of the seeds used. Exposure of Cu2O{111} and Cu2O{001} favored when the overgrowth happened on Au{111} and Au{001} surface, respectively. The size of the product can also be tuned by the amount of the seeds. The results reported here provide a thinking clue to modulate the shape and size of core-shell nanocrystals, which is useful in developing new materials with desired performance.

    Au/Cu bilayers with different Au:Cu concentrations (25:75, 50:50 and 75:25 at.%) were deposited on Si(100) substrates by thermal evaporation. The thicknesses of all Au/Cu bilayers were 150 nm. The alloys were prepared by thermal diffusion into a vacuum oven with argon atmosphere at 690 K during 1 h. X-ray diffraction analysis revealed different phases of AuCu and CuSi alloys in the samples after annealing process. CuSi alloys were mainly obtained for 25:75 at.% samples, meanwhile the AuCuII phase dominates for samples prepared with 50:50 at.%. Additionally, the Au:Cu alloys with 75:25 at.%, produce Au 2 Cu 3 and Au 3 Cu phases. The formed alloys were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS) to study the morphology and the elemental concentration of the formed alloys. - Highlights: • AuCu/Si alloy thin films were prepared by thermal diffusion. • Alloys prepared with 50 at.% of Au produce the AuCuII phase. • Alloys prepared with 75 at.% of Au produce Au 3 Cu and Au 2 Cu 3 phases. • All alloys present diffusion of Si and Cu through the CuSi alloy formation

    Star-shaped mesotructures are formed when an aqueous suspension of Au nanorice particles, which consist of prolate hematite cores and a thin Au shell, is subjected to an electric current. The nanorice particles assemble to form hyperbranched micrometer-scale mesostars. To our knowledge, this is the first reported observation of nanoparticle assembly into larger ordered structures under the influence of an electrochemical process (H(2)O electrolysis). The assembly is accompanied by significant modifications in the morphology, dimensions, chemical composition, crystallographic structure, and optical properties of the constituent nanoparticles.

    In this study, the adsorption of 2-butanol and furfural was investigated on Au (111), Cu (111) and Cu/Au (111) surfaces. It was hoped that by studying how these species adsorbed on these surfaces , insight would be provided into the roles of Cu and Au in the “hydrogen free” hydrogenation of furfural to furfuryl alcohol. This is a valuable process as currently furfuryl alcohol is derived from crude oil but it is possible to derive furfural from corn husk making it a greener process...

    Full Text Available El 27 de Agosto de 1995, Vernon Pugh, presidente de la comisión de la International Rugby Board (IRB para el amateurismo, declaró que el Rugby pasaba a ser un deporte libre. Se terminaba de esta forma con más de un siglo de amateurismo declarado en este deporte, y se terminaba también con una década de debates sobre el conocido shamateurismo, o profesionalismo encubierto, en el cual los jugadores no cobraban por jugar pero si por el trabajo, ya fuera real o ficticio, que le proporciona el club que defendían. En ese año, terminaba el anacronismo de un deporte de finales del S.XX sometido a reglas de la Inglaterra victoriana. ¿Como se pudo llegar a dicha situación? Dunning y Sheard argumentan que el fenómeno del amateurismo en el Rugby en el S.XIX fue un instrumento de diferenciación social complejo y que debe ser analizado desde un punto de vista histórico y sociopolítico. En esta línea, Bádenas expone que la aristocracia británica del S. XIX utilizó el interés creciente por la cultura griega antigua para atribuir unos valores al deporte practicado en aquella época de forma que se conceptualizó el deporte como una actividad lúdica propia de una élite social. Para lograrlo, ensalzaron los valores de un deporte amateur griego (que no existió como tal concepto y realzaron aquellos textos que criticaban la profesionalización de los deportistas y sus efectos sobre el deporte. Teóricos británicos, como Mahaffy atribuían al deporte griego antiguo unos valores que coincidían con el prototipo de gentlemen deportista de la época victoriana.-----------------------------------------------------------------The August 27, 1995, Vernon Pugh, chairman of the committee of the International Rugby Board (IRB for amateurism, said the Rugby happened to be a free sport.

    Full Text Available Changes in the area and volume that have been occurring from the middle of the XIX century within the largest in Europe Elbrus glaciation were studied using lichenometry and digital cartography methods. There were cyclical, approximately 55 years long, frontal fluctuations of glaciers Bolshoi Azau (the largest Elbrus glacier and Dzhankuat (which is representative of all Central Caucasus glaciation. Quantitative data on changes in the area and volume of the Elbrus glaciation indicated that the greatest rates of its retreat coincided with the 1850–1887 period. Beginning in 1887, the area reduction was occurring practically evenly through time while the decrease in its volume has even slowed down. These facts suggest that global climate warming, which alternated with short-term cooling periods, began in the middle of the XIX century after the end of the Little Ice Age. The warming was most likely due to natural rather than anthropogenic causes.

    Full Text Available Em um período em que estão em voga os debates ambientais, chama atenção o fato de que em uma cidade já massivamente urbana como Santa Maria/RS, 40% da sua população ainda enfrente problemas relacionados ao esgoto a céu aberto. Com base neste dado, procurou-se compreender qual o ponto de partida destes problemas sanitários da cidade, fazendo uma análise do seu primeiro projeto de saneamento, datado de 1918. Entretanto, ao investigar a respeito disto, notou-se que os debates em torno da salubridade local eram ainda mais longínquos, sendo encontradas discussões desde meados do século XIX. Portanto, para esta comunicação optou-se por fazer um balanço histórico a respeito da preocupação dos governantes locais com a saúde da população e com a higiene do espaço urbano de Santa Maria. Para tanto, serão abordados dois aspectos: a inserção dos médicos diplomados na cidade e a consolidação da elite médica local através de suas medidas de saúde pública. Dessa forma, acredita-se que será possível compreender como transcorreu todo o processo de construção das políticas públicas de saúde e higiene em Santa Maria/RS entre meados do século XIX e início do século XX. Destaca-se que esta ideia está pautada no conceito de saúde pública como todo tipo de ação coletiva visando melhorar os ambientes, elaborado por Dorothy Porter. Também se utiliza como base conceitos de políticas públicas em torno da saúde, compreendendo-as como um maior poder de intervenção do Estado nestas questões, cuja referência é o historiador Gilberto Hochman

    Full Text Available The English constitutional evolution in the XIXth century was characterized by its enormous adjustment capacity to a changeable situation stimulated by the economic development, leading the State to progressively abandon the “laisser faire” and take on more socially active duties, recognizing the economical-political power held by the new emerging powers, and concurrently extending the right of suffrage; in this way a permanent system of adjustment was establish between the political order and the new interests of the most powerful groups. However the extension of the right of suffrage was neither associated with a redistribution of the wealth, nor with a radical change in the structures of political domination; it’s the beginning of an evolution that, throughout the XIXth and the XXth century, will ultimately provoke the mutation in the conception of political representation.La evolución constitucional inglesa en el siglo XIX se caracterizó por la enorme capacidad de adaptación a una cambiante situación impulsada por el desarrollo económico, alteración que llevará progresivamente al Estado a abandonar el ‘laisser faire’ para asumir papeles socialmente más activos; reconociendo la fuerza económica y política de los nuevos poderes emergentes, a la vez que ampliaba progresivamente la base del sufragio. Se instaura así un sistema de ajuste permanente entre el orden político y los intereses de los grupos más poderosos. Pero la extensión del derecho de sufragio ni está asociada con una redistribución de la riqueza, ni con un cambio radical en las estructuras de dominación política; es el comienzo de una transformación que, a lo largo de los siglos XIX y XX, acabará provocando la mutación del concepto de representación política.

    The unique properties of gold especially in low temperature CO oxidation have been ascribed to a combination of various effects. In particular, particle sizes below a few nm and specific particle-support interactions have been shown to play important roles. On the contrary, recent reports revealed that monolithic nanoporous gold (npAu) prepared by leaching a less noble metal, such as Ag, out of the corresponding alloy can also exhibit remarkably high catalytic activity for CO oxidation, even though no support is present. Therefore, it was claimed to be a pure and unsupported gold catalyst. We investigated npAu with respect to its morphology, surface composition and catalytic properties. In particular, we studied the reaction kinetics for low temperature CO oxidation in detail taking mass transport limitation due to the porous structure of the material into account. Our results reveal that Ag, even if removed almost completely from the bulk, segregates to the surface resulting in surface concentrations of up to 10 at%. Our data suggest that this Ag plays a significant role in activation of molecular oxygen. Therefore, npAu should be considered as a bimetallic catalyst rather than a pure Au catalyst.

    Using low-temperature scanning tunnelling microscopy and spectroscopy we investigated the adsorption characteristics of 3,4,9,10-perylenetetracarboxylic-dianhydride and fullerenes on Au(788), Au(433), and Au(778). On Au(788) and Au(778), 3,4,9,10-perylenetetracarboxylic-dianhydride exhibits three coexisting superstructures, which do not reflect the periodicity of the hosting substrate. The adsorption on Au(433) leads to the formation of molecule chains along the step edges after annealing the sample. Fullerene molecules on Au(788) arrange in a mesh of islands, which extends over several hundreds of nanometres with an extraordinarily high periodicity. A combination of fullerene adsorption and annealing leads to facetting of Au(433) and the formation of extraordinarily long fullerene stripes

These western lands became part of the Russia by the decision of the Congress of Vienna in 1814-1815, which summarized the European wars of the allies against Napoleon. The Government embarked on the systematic development of the industry of the «Kingdom of Poland». The mining industry in this region was developed very well, but lacked local specialized educational institutions for the training of relevant personnel. On the basis of archival materials the author shows the process of organizing educational institutions that train personnel for the booming mining industry of this region. The first educational centers begin to appear immediately after joining Russia, however, difficult political events that began in the region from the 20s of XIX century interrupted the process of formation and development of mountain education in the «Kingdom of Poland» for several years. But in the second half of the XIX century it would again become a topical issue for the region. Particular attention is paid to the history of Dombrowa Mining School, which was established in 1889. The main purpose of this school was to prepare the mine managers and factory preachers to the needs of the mining industry in this region of the «Kingdom of Poland». Mining School in Dombrowa existed until the beginning of the First World War.

    We present a study of three-particle correlations among a trigger particle and two associated particles in Au+Au collisions at s NN =200 GeV using a multi-phase transport model (AMPT) with both partonic and hadronic interactions. We found that three-particle correlation densities in different angular directions with respect to the triggered particle ('center', 'cone', 'deflected', 'near' and 'near-away') increase with the number of participants. The ratio of 'deflected' to 'cone' density approaches to 1.0 with the increasing of number of participants, which indicates that partonic Mach-like shock waves can be produced by strong parton cascades in central Au+Au collisions

    Thiolate-protected gold nanoclusters have recently attracted considerable attention due to their size-dependent luminescence characterized by a long lifetime and large Stokes shift. However, the optimization of nanocluster properties such as the luminescence quantum yield is still a challenge. We report here the transformation of Au25Capt18 (Capt labels captopril) nanoclusters occurring at low pH and yielding a product with a much increased luminescence quantum yield which we have identified as Au23Capt17. We applied a simple method of treatment with HCl to accomplish this transformation and we characterized the absorption and emission of the newly created ligated nanoclusters as well as their morphology. Based on DFT calculations we show which Au nanocluster size transformations can lead to highly luminescent species such as Au23Capt17.

    We report the synthesis and characterization of pure and Au incorporated Alq3 nanowires. These nanowires are synthesized using thermal vapor transport method. The luminescence intensity of Au incorporated Alq3 nanowires are recorded to be higher than that of pure Alq3 nanowires, which is found to increase with the increase in Au concentration. Fluorescence quenching is also observed when Au concentration is increased beyond the certain limit.

    Our contribution focusses on one particular aspect of collective flow of nuclear matter: the so-called ''squeeze-out'', i.e. the preferential emission of mid-rapidity particles perpendicular to the reaction plane. The data were taken for the system 197 Au + 197 Au at 400, 600 and 800 MeV/u. We cover two topics, the comparison of neutrons and protons, and the bombarding energy dependence of the neutrons' squeeze-out. (orig.)

    Full Text Available Based upon a wide range of archive records, the article covers issues relating to particular aspects of life and living standards of silk weaving factory workers’ families in a village of Fryanovo of Moskovski county in XVIII — fi rst quarter of XIX centuries.Workers’ daily life was signifi cantly infl uenced by living conditions. It is via this article that we analyze dimensions and types of living premises provided to workers by the factory owners, as well as its improvements. The Fryanovo factory offi ce records that remain intact allow consideration of issues relating to food for workers, including sources for providing Fryanovo inhabitants with bread and other food products, the composition and the average amount thereof.One chapter of the article is specifi cally devoted to workers’ worship service attendance, as well as diff erences in religion belief of Fryanovo inhabitants. In addition to the orthodox Christian majority of its population, there were also Catholics and Old Believers among its inhabitants.The issues directly relating to working at the silk weaving factory include work schedule and rules, average age of workers, wage payment methods, as well as workers motivation by the silk weaving factory owner. Considered are the issues relating to employment of children and women at the silk weaving factory. An important part of the research relates to living conditions of non-working population groups: young children, retired and handicaps who were given some money or bread, on monthly bases, by silk weaving factory owners.Medical services for the silk weaving factory workers, personal taxation and other fees, participation by factory workers, in recruitments, penalties and fi nes system as implemented by the silk weaving factory in Fryanovo are also within the spectrum of questions that are discussed within the article.The fi nal chapter of the research points out the village inner life issues, such as alcohol abuse among

    The self-assembled fabrication of nanostructure, a dreaming approach in the area of fabrication engineering, is the ultimate goal of this research. A finding was proved through previous research that the size of the self-assembled gold nanoparticles could be controlled with the mole ratio between AuCl{sub 4}{sup -} and thiol. In this study, the moles of Au were fixed, only the moles of thiol were adjusted. Five different mole ratios of Au/S with their effect on size uniformity were investigated. The mole ratios were 1:1/16, 1:1/8, 1:1, 1:8, 1:16, respectively. The size distributions of the gold nanoparticles were analyzed by Mac-View analysis software. HR-TEM was used to derive images of self-assembled gold nanoparticles. The result reached was also the higher the mole ratio between AuCl{sub 4}{sup -} and thiol the bigger the self-assembled gold nanoparticles. Under the condition of moles of Au fixed, the most homogeneous nanoparticles in size distribution derived with the mole ratio of 1:1/8 between AuCl{sub 4}{sup -} and thiol. The obtained nanoparticles could be used, for example, in uniform surface nanofabrication, leading to the fabrication of ordered array of quantum dots.

    We report the STAR measurement of ψ meson production in Au + Au and p + p collisions at √s NN = 200 GeV. Using the event mixing technique, the ψ spectra and yields are obtained at midrapidity for five centrality bins in Au+Au collisions and for non-singly-diffractive p+p collisions. It is found that the ψ transverse momentum distributions from Au+Au collisions are better fitted with a single-exponential while the p+p spectrum is better described by a double-exponential distribution. The measured nuclear modification factors indicate that ψ production in central Au+Au collisions is suppressed relative to peripheral collisions when scaled by the number of binary collisions ( bin >). The systematics of T > versus centrality and the constant ψ/K - ratio versus beam species, centrality, and collision energy rule out kaon coalescence as the dominant mechanism for ψ production

    Azimuthal angular correlations of charged hadrons with respect to the axis of a reconstructed (trigger) jet in Au +Au and p +p collisions at √sNN =200 GeV in STAR are presented. The trigger jet population in Au +Au collisions is biased toward jets that have not interacted with the medium, allowing easier matching of jet energies between Au +Au and p +p collisions while enhancing medium effects on the recoil jet. The associated hadron yield of the recoil jet is significantly suppressed at high transverse momentum (pTassoc) and enhanced at low pTassoc in 0%-20% central Au +Au collisions compared to p +p collisions, which is indicative of medium-induced parton energy loss in ultrarelativistic heavy-ion collisions.

    We present transverse momentum distributions of charged hadrons produced in Au+Au collisions at sNN=200 GeV. The spectra were measured for transverse momenta pT from 0.25 to 4.5 GeV/c in a pseudorapidity range of 0.2<η<1.4. The evolution of the spectra is studied as a function of collision centrality, from 65 to 344 participating nucleons. The results are compared to data from proton-antiproton collisions and Au+Au collisions at lower RHIC energies. We find a significant change of the spectral shape between proton-antiproton and semi-peripheral Au+Au collisions. Comparing semi-peripheral to central Au+Au collisions, we find that the yields at high pT exhibit approximate scaling with the number of participating nucleons, rather than scaling with the number of binary collisions.

    Two different projectiles 208 Pb and 197 Au at the same energy (11.67MeV/u) have been bombarded on 197 Au target to study heavy ion interactions using mica as a passive detector. In this paper we present results on the study of energy damping and time scale of the existence of di-nuclear composite system in the intermediate reaction step. The plots of Q-values as well as reaction cross sections in various angular bins of scattering angles suggest that K.E. damping was complete and dynamic equilibrium was established between the first and second reaction steps. The time scale of this duration was also determined

    Seed-mediated growth of gold (Au) nanorods with highly controllable length, width, and aspect ratio was accomplished via carefully size-controlled synthesis of the original Au seeds. A slow dynamic growth of Au nanoparticle seeds was observed after reduction of the Au salt (i.e., hydrogen tetrachloroaurate (III) hydrate) by sodium borohydride (NaBH 4 ) in the presence of cetyltrimethyl ammonium bromide (CTAB). As such, the size of the Au nanoparticle seeds can therefore be manipulated through control over the duration of the reaction period (i.e., aging times of 2, 8, 48, 72, and 144 h were used in this study). These differently sized Au nanoparticles were subsequently used as seeds for the growth of Au nanorods, where the additions of Au salt, CTAB, AgNO 3 , and ascorbic acid were employed. Smaller Au nanoparticle seeds obtained via short growth/aging time resulted in Au nanorods with higher aspect ratio and thus longer longitudinal surface plasmon wavelength (LSPW). The larger Au nanoparticle seeds obtained via longer growth/aging time resulted in Au nanorods with lower aspect ratio and shorter LSPW.

    The STAR Collaboration presents for the first time two-dimensional di-hadron correlations with identified leading hadrons in 200 GeV central Au + Au and minimum-bias d + Au collisions to explore hadronization mechanisms in the quark gluon plasma. The enhancement of the jet-like yield for leading pions in Au + Au data with respect to the d + Au reference and the absence of such an enhancement for leading non-pions (protons and kaons) are discussed within the context of a quark recombination scenario. The correlated yield at large angles, specifically in the ridge region, is found to be significantly higher for leading non-pions than pions. The consistencies of the constituent quark scaling, azimuthal harmonic model and a mini-jet modification model description of the data are tested, providing further constraints on hadronization.

    Full Text Available This paper offers and analysis of the complex definition of the medical category «incurable disease» in the 19th century French medicine. After a detailed examination of several definitions of «disease» used in the period, I will focus on three intimately related categories: old age’s diseases, chronic diseases, and incurable diseases. A complex scene is presented, where these three categories worked in an institutional frame where we cannot distinguish one from another, and both the theoretical discourse and the medical practice show how they shared spaces, practices, and even representations.

    En el presente artículo se ofrece un análisis de la compleja definición del concepto de «enfermedad incurable» en la medicina francesa durante el siglo XIX. Tras un examen detenido de las distintas definiciones de «enfermedad» manejadas durante ese siglo, el texto se centra en el estudio de tres categorías íntimamente relacionadas: las enfermedades de la vejez, las enfermedades crónicas y las enfermedades incurables. Se presenta un panorama, tanto teórico como práctico, en el que estas tres categorías funcionan dentro de un marco institucional en el que, a todos los efectos, es prácticamente imposible diferenciar una de otras, al compartir tanto los espacios, como las prácticas e incluso las representaciones.

    Full Text Available O artigo aborda a disseminação das apostas em loterias durante as últimas décadas do século XIX no Brasil. Em especial, trata da primeira extração da Loteria de São Paulo, cujo objetivo era arrecadar fundos para a construção do Monumento do Ipiranga, no ano de 1880. Em um segundo momento, discute o empenho dos escravizados nas apostas de loterias como meio de amealhar recursos para financiar sua própria liberdade. Neste particular, descreve a trajetória do grupo de trabalhadores pelotenses que foi contemplado com o primeiro prêmio da Loteria do Ipiranga, cuja extração ocorreu em fevereiro de 1881, e analisa as consequências que a sorte na loteria trouxe à vida dos contemplados. Eles formavam um grupo misto de oito trabalhadores, separados por cor, gênero e posição social, que compreendia quatro homens e quatro mulheres; quatro brancos e quatro afrodescendentes; cinco livres, uma liberta e duas cativas. Apesar destas diferenciações, suas histórias guardam muitos pontos de semelhança entre si, com relação ao uso do dinheiro e a forma como eram tratados pela sociedade da época.

Por un lado, intenta superar la visión tradicional que ha hecho carrera y que presenta a la Costa como una región alejada de los conflictos nacionales del siglo XIX; y, por el otro, se muestran las distintas intenciones que escondía la entrada de los rostros diversos que participaban de las guerras. De esta manera, acudiendo a las experiencias del hacendado Manuel Burgos, del obispo Pedro María Revollo y del negro Joaquín Mercado Robles, se estudian varias de las motivaciones individuales y colectivas que se movieron entre los hombres de la región al ingresar en los escenarios de conflicto: el afán de mantener o fortalecer el poderío económico, la intención de defender y propagar el discurso político-religioso del catolicismo y la lucha por romper las estructuras raciales para alcanzar ascenso social y poder político.

    Full Text Available The social class structure of the Black sea tribes, the resettlement area which was the territory from Anapa to the river Bzyb, has not yet become a subject of research in the historiography. Natukhaitsy and shapsugs of Adygeyan tribe, ubykhs, and also jikis of Abaza tribe lived in the territory during the first half of the XIX century. The data sources on the population in this territory at a specified time are contradictory, thus practically does not reflect the proportion of estates. The authors attracted as sources the statistical materials of 1800-1860-ies, including those published in the modern period on the Abkhazia (Abaza tribe and the Kuban. By the comparison of the different sources there was made an attempt to calculate the proportion of the population on the estates, namely: the proportion of princes, nobles, free inhabitants, dependent inhabitants, slaves separately for coastal and mountain societies. In addition there were attracted the sources of personal origin – diaries and memoirs, the works of Abkhazians who lived among travelers, and, of course, the scientific literature. The authors used the methods of demographic statistics for reconstruction of the population of the tribes of the Black sea region due to the presence of incomplete data on the number of classes. In conclusion the research provides with the accumulated statistical data on total population, population class and gender.

    Full Text Available Até o último quartel do século XIX, a presença européia na África reduzia-se a poucos pontos litorâneos. Em toda a sua grande extensão, a África era governada por africanos. O continente dividia-se em impérios, reinos e cidades-estado. Do lado do Atlântico, havia intensas relações entre essas estruturas políticas e o Brasil. O que se passava num lado do oceano repercutia no outro. A cruzada anti-escravagista desembocou num novo imperialismo europeu. A ocupação da África pelas potências européias não logrou destruir muitas dessas estruturas de poder, algumas das quais serviram de intermediárias entre o colonizador e os africanos enquanto que outras persistiram na clandestinidade. A ocupação colonial ocasionou o quase completo corte das antigas e fortes relações com o Brasil.

A antiga noção de melancolia foi remodelada e sua transição para a doença depressiva foi facilitada pelo conceito de Iipemania de Esquirol, que, pela primeira vez, enfatizou a natureza afetiva primária da doença. Finalmente, uma vez obtidas as condições conceituais necessárias, a melancolia e a mania foram combinadas no conceito de insanidade alternante, periódica, circular, ou de forma dupla, seus rígidos padrões descritivos foram flexibilizados, tendo culminado este processo na sinopse de Kraepelin.

Se ha buscado documentación concerniente a periódicos de la ciudad en la época, documentos de asociaciones patronales en la ciudad, publicaciones de organizaciones de trabajadores y documentos del gobierno. Se ha concluido que la urbanización de Recife no implicó nuevas exigencias de profesionales, aunque existiera un discurso gubernamental que defendía espacios destinados a la instrucción profesional. La inexistencia de acciones de trabajadores y del patronato volcadas a la cualificación profesional se puede explicar en base a la incipiente industrialización. Se ha constatado que los criterios definidos para los contractos no se relacionaban directamente con la actividad que se desarrollaría. Las exigencias de los directivos se referían al sexo, al color, a la edad y a la conducta moral, sugiriendo que, si había una demanda respecto al saber hacer, no había criterios específicos relativos a la profesión solicitada.

    Full Text Available Este artículo comprende a la Ciudad de México de fines del siglo xix como un imaginario sonoro. Para analizar esta propuesta estética, la novela La Rumba, de Ángel de Campo, apodado Micrós, será el sujeto principal de análisis. Queremos evidenciar el entramado subyacente que forman las sonoridades de la cotidianeidad suburbana y la tensión dramática de la obra. Este ejercicio crítico estudia la forma en la que los cambios tecnológicos pueden modificar las estrategias narrativas y ayudar a construir aquello que se suele llamar marca de época: una suerte de tatuaje en la piel de la letra. En este marco, el artículo entiende el modo en el que Micrós utilizó diversas estrategias sensoriales, el oído, principalmente, para describir su ciudad imaginada, la ciudad imaginada por sus habitantes y aquella Ciudad de México del Porfiriato, que antes que urbe solo era un constructo ideal.

    Full Text Available El libro es la tesis doctoral realizada por Brenda Escobar en la Universidad Ludwig-Maximilian de Múnich. En su trabajo, se discute la importancia historiográfica dada a la adscripción partidista como factor que dividió la sociedad colombiana, especialmente a la idea de que el “compromiso partidista definiría las acciones de los colombianos en el siglo xix, tanto de la gente humilde como de los notables locales” (pág. 25, sustentada de manera reiterativa en la obra de Fernán González. En oposición a esta concepción, e influenciada por los estudios subalternos, la autora propone que en el caso del Tolima durante la Regeneración el bipartidismo no fue el principal motivo de oposición entre los sectores populares, y que cuando existían adscripciones partidistas estas no determinaban las conductas hacia otros, pues habría tenido más importancia la defensa de los intereses inmediatos y la supervivencia que la pertenencia a unas redes clientelistas y la herencia de odios de partido.

As a result of both, the historical events and the wakening of national consciousness, awareness for educational development was an unavoidable and important issue.Considering physical culture, educators who made efforts to provide developing of physical culture were mostly themselves educated abroad. The great step forward in the physical culture was made after Congress in Berlin in 1878 when Serbia was declared independent principality. The number of Serbian intellectuals came back in their country. They brought knowledge about certain sports and physical activities that were practiced in Europe at that time. Important part in the development of physical culture of our nation belonged to the army as the most organized institution. It sent its officers in the armies of great European nations to achieve and transfer knowledge to our people indirectly via army. One of the first officers educated in French Fencing School (Joinville le Pont back in 1902, Dragomir T. Nikolajevic brought in Serbia the first knowledge about both „English and French boxing – Savate“. Apart of training as a martial art teacher, he wrote the book „English and French Boxing“ published in Belgrade in 1914.

Su adhesión tardía a la independencia de Brasil (1823, el debate sobre la esclavitud y la explosión de la Cabanagem fueron procesos que tuvieron como protagonistas no sólo a las elites políticas lusobrasileñas, sino también a diferentes grupos cimarrones e indígenas que actuaban desde amplios e intrincados espacios de frontera, atentos a las ideas revolucionarias que provenían del exterior y que jugaron un papel fundamental en la construcción de la especificidad del norte de Brasil.

    Full Text Available Se analiza el tema del estatus de los afrodescendientes libres en las sociedades esclavistas más pobladas de América, desde el punto de vista de los derechos políticos y sociales de súbditos y ciudadanos. Con la carta de libertad, los antiguos esclavos y sus descendientes libres adquirieron teóricamente los mismos derechos y obligaciones que la población blanca eurodescendiente. Sin embargo, por razones de “seguridad pública” y de “mantención del orden establecido”, en la práctica, se establecieron restricciones y privilegios para mantener la distancia social entre blancos y afrodescendientes. Desde una perspectiva comparada se estudian Brasil, Cuba y los Estados Unidos, las tres sociedades esclavistas más notorias en América durante el siglo XIX, y se examina este proceso tomando como objetos de análisis los derechos de libre movimiento, el acceso a la enseñanza superior, el sufragio y la propiedad.

    We have measured transverse momentum distributions of charged hadrons produced in d+Au collisions at √SNN = 200 GeV, in the range 0.25 < pT < 6.0 GeV/c. With increasing collision centrality, the yield at high transverse momenta increases more rapidly than the overall particle density, leading to a strong modification of the spectral shape. This change in spectral shape is qualitatively different from observations in Au+Au collisions at the same energy. The results provide important information for discriminating between different models for the suppression of high-pT hadrons observed in Au+Au collisions.

    Incorporation of nano-sized metals in polymers can transfer their unique features to the host matrix, providing nanocomposite materials with improved optical, electric, magnetic and mechanical properties. In this work, colloidal Au nanorods have been incorporated into PMMA based random co-polymer, properly functionalized with amino groups and the optical and morphological properties of the resulting nanocomposite have been investigated by spectroscopic and AFM measurements. Au nanorods have demonstrated to preserve the plasmon absorption and to retain morphological features upon the incorporation, thus making the final metal modified polymer composite exploitable for the fabrication of plasmonic devices. The prepared nanocomposites have been then patterned by Nano Imprint Lithography technique in order to demonstrate the viability of the materials towards optical applications.

    Effective photoswitchable europium sulfide nanocrystals with gold nanoparticles using dithiol (DDT: 1,10-decanedithiol) joint molecules, EuS-Au nanosystems, are demonstrated. The TEM image indicates the formation of EuS-Au nanosystems composed of cube-shaped EuS nanocrystals and spherical Au nanoparticles. Under visible-light irradiation, a drastic change of absorption band of EuS-Au nanosystems at around 600 nm was observed. The Faraday effects of EuS-Au nanosystems were estimated using magnetic circular dichroism (MCD) measurements. The effective change of the MCD spectra of EuS-Au nanosystems under visible-light irradiation was successfully observed at around 670 nm for the first time. The effective reversible changes in MCD spectra with the alternative irradiation cycles of visible light (>440 nm) and dark are also presented. The decrease rate of rotation angle at 670 nm of EuS-Au nanosystems is larger than that of absorbance. These results indicate that the effective change of MCD spectra of EuS-Au nanosystems would be dominated not only by a drastic change of absorption band related to enhanced LSPR of Au nanoparticles but also by specific interaction between EuS and Au in nanosystem under irradiation.

    Full Text Available This manuscript describes a new type of nanomaterial, namely superparamagnetic Au@Co nanochains with optical extinctions in the near infrared (NIR. The Au@Co nanochains were synthesized via a one-pot galvanic replacement route involving a redox-transmetalation process in aqueous medium, where Au salt was reduced to form Au shells on Co seed templates, affording hollow Au@Co nanochains. The Au shells serve not only as a protective coating for the Co nanochain cores, but also to give rise to the optical properties of these unique nanostructures. Importantly, these bifunctional, magneto-optical Au@Co nanochains combine the advantages of nanophotonics (extinction at ca. 900 nm and nanomagnetism (superparamagnetism and provide a potentially useful new nanoarchitecture for biomedical or catalytic applications that can benefit from both activation by light and manipulation using an external magnetic field.

    2004-06-01

    Experimental Ti-Au alloys (5, 10, 20 and 40 mass% Au) were made. Mechanical properties and grindability of the castings of the Ti-Au alloys were examined. As the concentration of gold increased to 20%, the yield strength and the tensile strength of the Ti-Au alloys became higher without markedly deteriorating their ductility. This higher strength can be explained by the solid-solution strengthening of the a titanium. The Ti-40%Au alloy became brittle because the intermetallic compound Ti3Au precipitated intensively near the grain boundaries. There was no significant difference in the grinding rate and grinding ratio among all the Ti-Au alloys and the pure titanium at any speed.

    This paper describes the synthesis of Pd-Au bimetallic nanocrystals with controlled morphologies via a one-step seeded-growth method. Two different reducing agents, namely, L-ascorbic acid and citric acid, were utilized for the reduction of HAuCl(4) in an aqueous solution to control the overgrowth of Au on cubic Pd seeds. When L-ascorbic acid was used as the reducing agent, conformal overgrowth of Au on the Pd nanocubes led to the formation of Pd-Au nanocrystals with a core-shell structure. On the contrary, localized overgrowth of Au was observed when citric acid was used as the reducing agent, producing Pd-Au bimetallic dimers. Through this morphological control, we were able to tune the localized surface plasmon resonance peaks of Pd-Au bimetallic nanostructures in the visible region.

    Polypyrrole films containing gold nanoparticles (PPy/Au) were electrosynthesized on a glassy carbon electrode. This was done by applying a constant current of 1.43 mA cm{sup -2} in solutions containing colloidal Au particles and pyrrole monomer. A chloroaurate medium with a citrate/tannic acid reducing/protection agent was employed for generating the Au colloids. The PPy/Au films were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Raman spectroscopy. Also, electrochemical behaviors of the PPy/Au films were characterized by cyclic voltammetry (CV) and AC impedance measurements. Experimental results demonstrate that PPy/Au has greater conductivity and better stability than PPy. The effect of incorporated Au nanoparticles in PPy matrix was studied and the mechanism was suggested.

    Au nanowires with length up to micrometers were synthesized through a simple and one-pot solution growth method. HAuCl{sub 4} was reduced in a micellar structure formed by 1-octadecylamine and oleic acid in hexane, heptane, toluene and chloroform, respectively. As the non-polarity of noncoordinating solvents can affect the nucleation and growth rates of Au nanostructures, Au nanowires with different diameters could be obtained by changing the noncoordinating solvents in the synthetic process. The influences of the solvents on the morphology of Au nanowires were systematically studied. When using hexane as reaction solvent, the product turned to be high portion of Au nanowires with more uniform size than the others. Furthermore, surface-enhanced Raman scattering (SERS) spectrum of 2-thionaphthol was obtained on the Au nanowire-modified substrate, indicating that the as-synthesized Au nanowires have potential for highly sensitive optical detection application.

    Polyethylene (PE) surface was treated with Ar plasma. Activated surface was grafted from methanol solution of 1,2-ethanedithiol. Then the sample was immersed into freshly prepared colloid solution of Au-nanoparticles. Finally Au layer was sputtered on the samples. Properties of the modified PE were studied using various methods: AFM, EPR, RBS and nanoindentation. It was shown that the plasma treatment results in degradation of polymer chain (AFM) and creation of free radicals by EPR. After grafting with dithiol, the concentration of free radicals declines. The presence of Au and S in the surface layer after the coating with Au-nanoparticles was proved by RBS. Plasma treatment changes PE surface morphology and increases surface roughness, too. Another significant change in surface morphology and roughness was observed after deposition of Au-nanoparticles. Nanoindentation measurements show that the grafting with Au-nanoparticles increases adhesion of subsequently sputtered Au layer.

    Ionic complexes between gold and C 60 have been observed for the first time. Cations and anions of the type [Au(C 60 ) 2 ] +/- are shown to have particular stability. Calculations suggest that these ions adopt a C 60 -Au-C 60 sandwich-like (dumbbell) structure, which is reminiscent of [XAuX] +/- ions previously observed for much smaller ligands. The [Au(C 60 ) 2 ] +/- ions can be regarded as Au(I) complexes, regardless of whether the net charge is positive or negative, but in both cases, the charge transfer between the Au and C 60 is incomplete, most likely because of a covalent contribution to the Au-C 60 binding. The C 60 -Au-C 60 dumbbell structure represents a new architecture in fullerene chemistry that might be replicable in synthetic nanostructures.

  3. Solvent extraction of Au(III) for preparation of a carrier-free multitracer and an Au tracer from an Au target

    Separation of Au(III) and various carrier-free radionuclides by solvent extraction was investigated using an Au target irradiated by an energetic heavy-ion beam. Percentage extraction of Au(III) and coextraction of the radionuclides were determined with varying parameters such as kinds of solvent, molarity of HCl or pH, and Au concentration. Under the conditions where Au(III) was effectively extracted, namely extraction with ethyl acetate or isobutyl methyl ketone from 3 mol*dm -3 HCl, carrier-free radionuclides of many elements were found to be more or less coextracted. Coextraction of radionuclides of some elements was found to increase with an increase in the concentration of Au(III). This finding is ascribed to the formation of strong association of the complex of these elements with chloroauric acid. In order to avoid serious loss of these elements by the extraction, lowering of the Au(III) concentration or the use of a masking agent such as sodium citrate is necessary. Gold(III) was shown to be effectively back extracted with a 0.1 mol*dm -3 aqueous solution of 2-amino-2-hydroxymethyl-1,3-propanediol. Thus, a radiochemical procedure has been established for preparing a carrier-free multitracer and an Au tracer with carrier form from an Au target irradiated with a heavy-ion beam. Both tracers are now used individually for chemical and biological experiments. (author). 22 refs., 3 figs., 2 tabs

    Au/Co/Au trilayers are interesting for a range of applications which exploit their unusual optical and electronic transport behaviour in a magnetic field. Here we present a comprehensive structural and morphological study of a series of trilayers with 0-7 nm Co layer thickness fabricated on glass by ultrahigh vacuum vapour deposition. We use a combination of in situ electron diffraction, atomic force microscopy and x-ray scattering to determine the optimum deposition conditions for highly textured, flat and continuous layered structures. The 16 nm Au-on-glass buffer layer, deposited at ambient temperature, is found to develop a smooth (1 1 1) texture on annealing at 350 deg. C for 10 min. Subsequent growth of the Co layer at 150 deg. C produces a (1 1 1) textured film with lateral grain size of ∼150 nm in the 7 nm-thick Co layer. A simultaneous in-plane and out-of-plane Co lattice expansion is observed for the thinnest Co layers, converging to bulk values for the thickest films. The roughness of the Co layer is similar to that of the Au buffer layer, indicative of conformal growth. The 6 nm Au capping layer smoothens the trilayer surface, resulting in a surface roughness independent of the Co layer thickness

    High-coercivity Au(60 nm)/FePt(δ nm)/Au(60 nm) trilayer samples were prepared by sputtering at room temperature, followed by post annealing at different temperatures. For the sample with δ=60 nm, L1 ordering transformation occurs at 500 deg. C. Coercivity (H c ) is increased with the annealing temperature in the studied range 400-800 deg. C. The H c value of the trilayer films is also varied with thickness of FePt intermediate layer (δ), from 27 kOe for δ=60 nm to a maximum value of 33.5 kOe for δ=20 nm. X-ray diffraction data indicate that the diffusion of Au atoms into the FePt L1 lattice is negligible even after a high-temperature (800 deg. C) annealing process. Furthermore, ordering parameter is almost unchanged as δ is reduced from 60 to 15 nm. Transmission electron microscope (TEM) photos indicate that small FePt Ll particles are dispersed amid the large-grained Au. We believe that the high coercivity of the trilayer sample is attributed to the small and uniform grain sizes of the highly ordered FePt particles which have perfect phase separation with Au matrix

    Au38(SR)24 is one of the most extensively investigated gold nanomolecules along with Au25(SR)18 and Au144(SR)60. However, so far it has only been prepared using aliphatic-like ligands, where R = –SC6H13, -SC12H25 and –SCH2CH2Ph. Au38(SCH2CH2Ph)24 when reacted with HSPh undergoes core-size conversion to Au36(SPh)24, and existing literature suggest that Au38(SPh)24 cannot be synthesized. Here, contrary to prevailing knowledge, we demonstrate that Au38(SPh)24 can be prepared if the ligand exchanged conditions are optimized, without any formation of Au36(SPh)24. Conclusive evidence is presented in the form of MALDI-MS, ESI-MS characterization, and optical spectra of Au38(SPh)24 in a solid glass form showing distinct differences from that of Au38(S-aliphatic)24. Theoretical analysis confirms experimental assignment of the optical spectrum and shows that the stability of Au38(SPh)24 is comparable to that of its aliphatic analogues, but results from different physical origins, with a significant component of ligand-ligand attractive interactions.

This search is based on data collected by the CHIMERA collaboration for the Au + Au reaction at 15 MeV/nucleon. The beam time needed to achieve this goal is calculated for events with at least 5 heavy fragments. We found that the fraction of such events among the accumulated data is equal to 8*10 -4 . Assuming the Au beam intensity is 0.03 pnA and target thickness equals 0.3 mg/cm 2 we estimated that 450 hours of beam time is needed to record 10 6 multifragment events. Present status of the Monte-Carlo simulation predictions is shortly discussed. (A.C.)

    Au:oxide composite multilayer films with Au nanoparticles sandwiched by oxide layers (such as SiO2, ZnO, and TiO2) were prepared in a magnetron sputtering system. Their photoluminescence (PL) spectra were investigated by employing a micro-Raman system in which an Argon laser with a wavelength of 514 nm was used as the pumping light. Distinct PL peaks located at a wavelength range between 590 and 680 nm were observed in most of our samples, with Au particle size varying from several to hundreds of nanometers. It was found that the surface plasmon resonance (SPR) in these composites exerted a strong influence on the position of the PL peaks but had little effect on the PL intensity.

    Au:oxide composite multilayer films with Au nanoparticles sandwiched by oxide layers (such as SiO 2 , ZnO, and TiO 2 ) were prepared in a magnetron sputtering system. Their photoluminescence (PL) spectra were investigated by employing a micro-Raman system in which an Argon laser with a wavelength of 514 nm was used as the pumping light. Distinct PL peaks located at a wavelength range between 590 and 680 nm were observed in most of our samples, with Au particle size varying from several to hundreds of nanometers. It was found that the surface plasmon resonance (SPR) in these composites exerted a strong influence on the position of the PL peaks but had little effect on the PL intensity

    Metal-oxide heterostructures have been attracting considerable attention in recent years due to various technological applications. We present results of electronic structure and transport calculations for the Au-MgO-Au (metal-insulator-metal) heterostructure based on density-functional theory and the nonequilibrium Green’s functions method. The dependence of the conductance of the heterostructure on the thickness of the MgO interlayer and the interface spacing is studied. In addition, we address the effects of O vacancies. We observe deviations from an exponentially suppressed conductance with growing interlayer thickness caused by Au-O chemical bonds. Electronic states tracing back to O vacancies can increase the conductance. Furthermore, this effect can be enhanced by enlarging the interface spacing as the vacancy induced Mg states are shifted toward the Fermi energy.

    The Au(CN)(2)(-) ion is the most stable Au compound known for centuries, yet a detailed understanding of its chemical bonding is still lacking. Here we report direct experimental evidence of significant covalent bonding character in the Au-C bonds in Au(CN)(2)(-) using photoelectron spectroscopy and comparisons with its lighter congeners, Ag(CN)(2)(-) and Cu(CN)(2)(-). Vibrational progressions in the Au-C stretching mode were observed for all detachment transitions for Au(CN)(2)(-), in contrast to the atomic-like transitions for Cu(CN)(2)(-), revealing the Au-C covalent bonding character. In addition, rich electronic structural information was obtained for Au(CN)(2)(-) by employing 118 nm detachment photons. Density functional theory and high-level ab initio calculations were carried out to understand the photoelectron spectra and obtain insight into the nature of the chemical bonding in the M(CN)(2)(-) complexes. Significant covalent character in the Au-C bonding due to the strong relativistic effects was revealed in Au(CN)(2)(-), consistent with its high stability.

    The first measurements of φ meson production in Au-Au collisions at AGS energies are presented via the decay to K + K - . A measurement of the centrality dependence of the yield shows an increase similar to that seen for the K - with a spectral shape consistent with a relativistic Breit-Wigner distribution within the statistical errors of the present data set. Future analysis using the full data set with 4 times the statistics will allow a more accurate determination of the yields, slopes and spectral shapes

    Elliptic flow from nuclear collisions is a hadronic observable sensitive to the early stages of system evolution. We report first results on elliptic flow of charged particles at midrapidity in Au+Au collisions at sNN = 130 GeV using the STAR Time Projection Chamber at the Relativistic Heavy Ion Collider. The elliptic flow signal, v2, averaged over transverse momentum, reaches values of about 6% for relatively peripheral collisions and decreases for the more central collisions. This can be interpreted as the observation of a higher degree of thermalization than at lower collision energies. Pseudorapidity and transverse momentum dependence of elliptic flow are also presented.

    The balance function is a new observable based on the principle that charge is locally conserved when particles are pair produced. Balance functions have been measured for charged particle pairs and identified charged pion pairs in Au + Au collisions at √sNN = 130 GeV at the Relativistic Heavy Ion Collider using STAR. Balance functions for peripheral collisions have widths consistent with model predictions based on a superposition of nucleon-nucleon scattering. Widths in central collisions are smaller, consistent with trends predicted by models incorporating late hadronization

    The electronic energy loss for low velocity protons channeled in the <100> direction single crystal Au is calculated. The spatial distribution of valence electronic density in Au is calculated using Tight Binding Linear Muffin Tin Method. The proton trajectories are determined by numerical integration of the classical motion equation, and the energy loss is evaluated using the calculated valence electronic density in the friction term. The results allow to describe qualitatively the non linear behavior of energy loss with ion velocity observed experimentally. (author). 14 refs., 4 figs.

    The first measurements of light antinucleus production in Au + Au collisions at the Relativistic Heavy-Ion Collider are reported. The observed production rates for d and /sup 3/He are much larger than in lower energy nucleus-nucleus collisions. A coalescence model analysis of the yields indicates that there is little or no increase in the antinucleon freeze-out volume compared to collisions at CERN SPS energy. These analyses also indicate that the 3He freeze-out volume is smaller than the d freeze-out volume. (22 refs).

    Using charged-particle-exclusive measurements of Au+Au collisions in the LBL Bevalac's EOS time projection chamber, we investigate momentum-space densities of fragments up to 4 He as a function of fragment transverse momentum, azimuth relative to the reaction plane, rapidity, multiplicity, and beam energy. Most features of these densities above a transverse momentum threshold are consistent with momentum-space coalescence, and, in particular, the increase in sideward flow with fragment mass is generally well described by a momentum-space power law

    We present the first measurement of the pseudorapidity density of primary charged particles in Au+Au collisions at (sNN) = 200 GeV. For the 6% most central collisions, we obtain dNch/dη\\|\\|η\\|<1 = 650+/-35(syst). Compared to collisions at (sNN) = 130 GeV, the highest energy studied previously, an increase by a factor of 1.14+/-0.05 at 90% confidence level, is found. The energy dependence of the pseudorapidity density is discussed in comparison with data from proton-induced collisions and theoretical predictions.

    The PHOBOS collaboration has carried out a systematic study of charged particle multiplicities in Cu+Cu and Au+Au collisions at the Relativistic Heavy-Ion Collider (RHIC) at Brookhaven National Laboratory. A unique feature of the PHOBOS detector is its ability to measure charged particles over a very wide angular range from 0.5° to 179.5° corresponding to |η| <5.4. The general features of the charged particle multiplicity distributions as a function of pseudo-rapidity, collision energy and centrality, as well as system size, are discussed.

    We grew high-quality single crystals of AuAl2, AuGa2, and AuIn2 with the fluorite (CaF2)-type cubic structure and determined the Fermi surface properties by the de Haas-van Alphen (dHvA) experiments using full-potential LAPW bad calculations. The Fermi surface and optical properties for three compounds were once studied from an interest of colors because AuAl2 has a striking bright reddish-purple color, whereas AuGa2 and AuIn2 are, respectively, neutral and bluish. The detected dHvA frequencies in the present study are found to be in a wide range of (0.1-13)×107 Oe. The main dHvA branches for three compounds are in excellent agreement with the theoretical ones, but some dHvA branches with small dHvA frequencies are slightly deviated from the theoretical ones, especially in AuGa2 and AuIn2.

    Full Text Available ResumenSe estudian los usos de la palabra chino, china en el norte peruano, entre los siglos XVIII y XIX, a partir de documentos históricos y coplas de la lírica popular. En contra de propuestas anteriores, se confirma el uso efectivo del término, sobre todo en su forma femenina, y se postulan dos acepciones: la primera, vinculada a la terminología de castas, alude a un tipo de mestizaje que une los troncos indio y africano, con un componente menor, variable, de “sangre blanca”, mientras que la segunda hace referencia a una mujer joven, generalmente campesina. Se estudia también el uso de la palabra como una fórmula de apelación a la amada en la lírica popular y se concluye que, aunque probablemente esta fórmula se derivó de la terminología racial, la palabra rápidamente adquirió matices afectivos positivos, con lo cual permitió aludir a la mujer cercana, aquella que era posible cortejar. Se sugiere que la antigua acepción ‘criada’, central en las fuentes coloniales del XVI y el XVII, se empezó a desdibujar en el período estudiado y, en línea con trabajos previos, se postula una competencia entre este lexema y la palabra homófona referida a las migrantes asiáticas desde fines del XIX.Palabras clave: categorización racial de seres humanos, lexicología, norte del Perú, siglos XVIII y XIXAbstractThis paper studies the uses of the word chino, china in northern Peru in the eighteenth and nineteenth centuries, via historical documents and popular poetry couplets. Contrary to previous proposals, we corroborate the actual use of this term, especially in its feminine form, and we propose two possible meanings for it: the first, linked to caste terminology, refers to a type of “racial mix” between “Indian” and “African”, with a minor and variable component of “white blood”, while the second refers to a young woman, usually a peasant. We also examine the use of the word as a formulaic

    Full Text Available Spain, in general, and Galicia, in particular, stayed away from the Grand Tour, major exponent of the modern tourism born in Great Britain. The ignorance of the land and the poor ground transportation contributed to this distance, among other things. In this way, the paper focuses in the analysis of both obstacles in the first tourism development in Galicia, between the late eighteenth century and the mid-nineteenth century, before the railway construction. On the one hand, it analyses the image that some foreign travelers offered about their travels in Galicia, and, on the other hand, it studies the state of the ground transportation during the period. The foreign testimonies about the Galician region were short compared with other parts of the peninsula. Although they relieved in certain degree the ignorance about Galicia with the marking of some points of future tourist interest. At last, several and partial improvements in the ground transportation were made in the last third of the eighteenth century.España, en general, y Galicia, en particular, permanecieron alejadas de las rutas del Grand Tour, exponente principal del turismo moderno iniciado en Gran Bretaña. El desconocimiento del territorio y el deficiente estado de los transportes terrestres contribuyeron a este alejamiento, entre otros factores. Así, el trabajo se centra en el análisis de ambos obstáculos al primer desarrollo del turismo en Galicia entre finales del siglo XVIII y mediados del siglo XIX, antes de la construcción del ferrocarril. Por un lado, se analiza la imagen que ofrecieron algunos viajeros extranjeros en sus crónicas de viaje por tierras galaicas y, por otro lado, se estudia el estado del transporte terrestre de la época. Se observa que los testimonios forasteros sobre la región gallega resultaron escasos en comparación con otros puntos peninsulares aunque aliviaron en cierto grado el desconocimiento que pesaba sobre la comunidad, marcando una serie de

    Full Text Available Resumo Este artigo analisa parte do discurso que a Igreja Católica teceu sobre as mulheres, enfatizando o tema da maternidade durante o século XIX. O enfoque parte da Bulla Sylabus (1864, expedida no pontificado de Pio IX, e da encíclica Rerum Novarum (1891, do Papa Leão XIII. Entre a segunda metade do século XIX e a Primeira Guerra Mundial, a Igreja passou pelo processo conhecido como "romanização", caracterizado pela preocupação moral e disciplinar do clero diante de críticas do laicado, além da promoção de ordens e congregações religiosas. O objetivo deste artigo é, portanto, discutir como aquela instituição definiu um papel social feminino vinculado à ideia do amor materno, divulgado como natural e incondicional. A partir da contribuição dos estudos de gênero, aborda a atribuição de características masculinas e femininas para a distinção não apenas biológica entre homens e mulheres. Concluiu-se que, na longa duração, o discurso católico passou de uma postura misógina - de recusa do sexo feminino - à incorporação das mulheres como público essencial para a sustentação do catolicismo diante das propostas de laicização da sociedade ocidental contemporânea. Palavras-chave: Mulheres; Discurso católico; Maternidade; Gênero. AbstractThis paper discusses part of the discourse that the Catholic Church built in order to define woman's role in the 19th century, emphasizing representations of motherhood. The focus starts with Pius IX's Bulla Sylabus (1864 and Pope Lion XIII's Rerum Novarum (1891. Between the second half of the 19th century and World War I, the Catholic Church underwent a process known as "Romanization", characterized by the clergy's moral and disciplinary concern in face of the laity's criticism, and by the promotion of new religious orders and congregations. The paper considers, therefore, how the Catholic Church defined a social female role linked to the idea of maternal love, diffused as

    Full Text Available The article is devoted to the study of the role and place of students in the Siberian scientific-research and cultural-educational life of the region. It is shown that high moral ideals and a desire to help people in need be useful to its edge and to society in general – describe the ideas, common in the student's environment at the turn of XIX – XX centuries. Based on the analysis of archival materials and scientific literature, it was found that the students showed during this period, an increased desire to participate in social and cultural life of Siberia and the whole country. However, this participation in different ways manifested in the minds and actions of young people. Some students, actively engage in the cultural life of the region, entered in the companies involved in charity work, academic research, literary and theatrical art, medicine, advanced study of philosophy, technical processes, etc. At universities created various thematic interest groups, on a territorial basis – numerous fraternities, a nobility of purpose in the form of moral and material support of their members. However, some Siberian students in their own way understood his own mission in social processes, including under the form of participation in legal societies, clubs or fraternities in the activities of political and campaign focus, in the meetings discussing ideas about the possibilities of revolution, as expected, from their point of view, progress and prosperity in case of their implementation. Also in this period, there are illegal organizations that engage some students of Siberian universities. The activities of such organizations is highly political in nature.

    Full Text Available In this article we try to analyze the first three decades of the 19th century in the Río de la Plata region through the lives of two important Franciscans. Using civil and ecclesiastical documents, sermons and newspapers we will try to identify in which ways, different events changed the lives of two members of the Catholic Church. Two life stories are the windows to analyze the effect of the Bourbon Reforms at a local level, the impact of the revolution inside and outside the convents, the ideological transformation of the Clergy and the different attitudes towards the ecclesiastical reforms of the 1820s.En este trabajo, de carácter exploratorio, he procurado realizar un recorrido histórico de las primeras tres décadas del siglo XIX en el Río de la Plata a través de la vida de dos importantes franciscanos.

    Full Text Available ¿Como eran enfrentados los desastres naturales en los siglos XVIII y XIX, cuando no existían los mecanismos institucionales que hoy conocemos bajo el moderno concepto de la 'prevención de desastres', con todo su sistema de ayudas tecnológicas, médicas e institucionales? Los desastres se asemejan a las enfermedades, al ser un elemento de desorganización social y un factor de temido desarreglo para la vida cotidiana, por lo que permiten hacer visibles las articulaciones internas de una sociedad y las tensiones que la atraviesan. Son un punto privilegiado para percibir el significado de mecanismos administrativos y prácticas religiosas en torno a fenómenos que vulneran una comunidad, así como la imagen que una sociedad tiene de sí misma. A pesar de que los archivos coloniales y republicanos poseen información dispersa sobre el tema, es posible identificar la manera como se sucedían con recurrencia fuertes temporadas de invierno que obstaculizaban el comercio y la movilización de personas y mercancías. Los documentos históricos también permiten conocer la ocurrencia de tempestades, granizadas, inundaciones, largas temporadas de sequía, vendavales, erupciones volcánicas, terremotos y deslizamientos de tierra y lodo. que podían arrasar cultivos, animales del campo y poblaciones enteras. Al hecho de que sucedieran estos eventos, contribuían las acciones humanas de intervención sobre los paisajes naturales.

    Full Text Available In the present article mechanisms of penetration of persons of clergy origin into the elite of Russian Empire in XVIII - fi rst quarter of XIX century is to be analysed. The term «elite» means the military and state «generals», which achieved 1-5 ranks under the Table of Ranks. We found an extremely small number of people of clergy origin among the elite of Russian Empire. What hindered the advancement of clergy? The author proposes that the significance of the Table of Ranks and of the system of promotion in rank as a social elevator for persons of not-noble origin was overpriced, and also highlights the inertia of pre-Petrine localism. The system of matrimonial ties and of patronage to relatives backed by the economic power based on large land ownership allowed boyar aristocracy get a strong position and high ranks among the new elite during the reforms of Peter the Great. Therefore it was quite difficult for people of clergy and else not-noble origin to achieve high ranks. In addition the Church administration cared about its own personnel and resisted moving of talented seminarists to the civil service. The analysis of the data shows that patronage was one of the decisive factors of vertical social mobility for persons of clergy origin. Many former seminarists entered the civil service, but three cases of seven mentioned in the article are connected with military service. Everyone was under patronage of a powerful authority, often serving as an aide-decamp or a secretary. There were two barriers: the rejection of aristocracy to the priests’ sons and the corporatism of Church administration and education and in general the closedness of clergy of the Synodal period

    Full Text Available The domestic Caucasus Studies contains various, often conflicting concepts and approaches, claiming to be the most complete and objective coverage of issues of Russian-Caucasian historical interaction. Though in different studies, the same category is filled with a variety of semantic content that creates a discursive field requiring thorough scientific research. The article analyzes the research works of official direction of pre-revolutionary historiography devoted to the problem of relations between Russia and the North Caucasus in the XVI–XIX centuries. The disciplinary matrix of historical science of J. Ryuzen is used as an instrument of historiographical analysis in this research. This theoretical construct allowed to typologize and to conceptualize the pre-revolutionary studies, to formulate criteria for selection of the conservative direction in the study of the Russian-Caucasian relations. The authors of the article relate the works of M.M. Shcherbatov, N.K. Karamzin, P.P. Zubov, R.А. Fadeev, A.P. Berge, N.F. Dubrovin, V.A. Potto, D.N. Dubenskiy, I. Ivanin, S.S. Esadze et al to the research works of the official direction of the pre-revolutionary historical thought. The cognitive interest of this group of researchers is caused by the search for the most effective ways of conquest and managing the North Caucasian peoples. Caucasus war was examined by the researchers-conservatives as the process of strengthening the position of the Russian Empire in the North Caucasus region justified from a historical and geopolitical point of view. The official approach supposed the civilizational motivation for the particular military conquest of the North Caucasus societies, deprived of citizenship and social order. The authors conclude that the research works of the conservative direction of imperial historiography solve important problems of legitimation of the Russian policy in the North Caucasus.

    Full Text Available The article discusses the role of the Russian Orthodox Church in the outlook of the peasantry in Russia in XIX – early XX centuries. It is shown that the priests have helped peasants in their households and even in the sickness, for which they used their special favour. In addition, our attention is given to the Orthodox Church holidays, with which the peasants tied the most significant events in their lives. We have analyzed the value of the parish in the life of the peasants, which determines the formation of the moral character of the peasantry. The attitude of the peasants to the different events, their assessment were often based on the judgment of the priest, not only obliged to hold services in the Church, but also to carry on business, has become a factor of integration of the clergy in the world of Russian village. In the article, on the archive material, the charity of peasants is differentiated. The peasants took an active part in the affairs of philanthropy, not only in their parishes or dioceses, but also in charity events throughout Russia. The scientific problem solved in this article makes it possible to identify that it is in the village of Russian Orthodox Church rallied the population, and it was considered citizens as a spiritual institution, where the cleric was in constant and close contact with the peasants, with the result that there is a certain transformation in the national consciousness. On the specific examples given in the article, we can say that the priests were authentic spiritual teachers of their congregations. Cautionary preaching of the clergy has played an important role in ritual and religious life of the Russian peasants.

    Full Text Available Desde la Carta de Atenas se ha manifestado una preocupación por conservar aquellos elementos que marcan el desarrollo de una cultura determinada, y que por sus valores se denominan patrimoniales. El patrimonio existente, el inmueble, por sus características, es uno de los que tienen mayor permanencia en el tiempo, y forma parte de la memoria de un pueblo. Sin embargo la preocupación por preservar y restaurar dicho patrimonio se ha centrado en aquellas construcciones del pasado anteriores al siglo XX, y cuando mucho en las de la primera mitad de dicho siglo. Sin embargo está visto que el hombre sigue haciendo historia, y existen edificaciones que van marcando el ritmo de esa historia. Tal es el caso de las edificaciones que se hicieron con motivo de la XIX Olimpiada en México, que detentan parte del legado artístico, arquitectónico y urbanístico que dejó dicho evento, el cual corre el riesgo de perderse ante la incorporación de la Ciudad de México al desarrollo y crecimiento económico que marcan las tendencias globales. Es por esto que a través de un análisis socio-histórico, dentro del Método de la Hermenéutica Profunda de John B. Thompson, y partiendo de información documental y de campo, se establece cuáles fueron las edificaciones que albergaron este evento, su situación actual, así como su importancia y la necesidad de su puesta en valor para su cuidado histórico y la promoción de la cultura y el deporte, para con ello contribuir al desarrollo económico, político, social y comunitario de la urbe.

    Full Text Available The ideas about race developed in Mexico at the end of 19th Century established a link between the ethnic groups’ phisiological features and their mental or moral inclinations through which the «national character» was formed. The Revolution did not change this view which nurtured the new anthropological, ethnological, and biotypological studies carried out within the «social engineering» program launched as from the twenties. In this program a series of policies —regarding metissage, migrations, education, as well as sanitary, profilactic and iuridical questions— were defined, all of which held to the idea that the racial transformation of the country was linked to changes in mentalities and the definition of a new public and private morale.

    El pensamiento sobre las razas que se desarrolló en México a fines del siglo XIX estableció una vinculación entre los rasgos fisiológicos y las inclinaciones mentales o morales de los grupos étnicos, a partir de las cuales se conformaba un «carácter nacional». Este planteamiento no se transformó radicalmente después de la Revolución sino que fue recuperado en los nuevos estudios antropológicos, etnológicos y biotipológicos que alimentaron el programa de «ingeniería social» puesto en marcha a partir de los años veinte. Dentro de este programa fueron definidas un conjunto de políticas de mestizaje, migratorias, educativas, sanitarias, profilácticas y jurídicas que siguieron asociando la transformación racial del país al cambio de las mentalidades y a la definición de una nueva moral pública y privada.

    Full Text Available La aparición en un archivo particular de la localidad burgalesa de Pradoluengo, del libro de cuentas de Manuel Martínez Lerma, y su análisis desde los puntos de vista formal, conceptual y de contenidos, supone uno de los pocos casos sobre contabilidad privada, estudiados en el ámbito rural castellano de la primera mitad del siglo XIX.                   En su funcionamiento interno, este documento contable es deudor de la tradición castellana. Su fin es eminentemente práctico y su contexto cronológico le hace no estar sujeto a supervisiones de estamentos superiores, lo que le otorga una verosimilitud prácticamente absoluta. Sin lugar a dudas, supuso la piedra angular del trabajo de despacho de su redactor, quien, a pesar de declarar como actividad principal la de escribano, diversificó sus negocios en multitud de ámbitos: fabricación de tejidos, comercio al por menor, actividades financieras y de préstamo, compraventa de lanas, adquisición de tierras e inmuebles, etcétera.                  La versatilidad de nuestro personaje, se plasma en múltiples perspectivas que manan constantemente del libro de cuentas, cuyo análisis hemos apoyado con documentación notarial, parroquial y municipal. Manuel se situará progresivamente en lo más alto de la cúspide social, estableciendo relaciones clientelares con grandes comerciantes, convirtiéndose en un destacado fabricante local, accediendo a puestos de responsabilidad municipal, fijando alianzas matrimoniales ventajosas para sus hijos, o siendo pieza clave en el encumbramiento de uno de ellos como arzobispo de Manila.

    Landaburu, Alejandra

    2015-11-01

    Full Text Available El objetivo de este trabajo es establecer cuáles eran los beneficios sociales otorgados por los propietarios de ingenios en sus fábricas y qué relación tenían estos beneficios con las concepciones que tenían los industriales en torno a la “cuestión social” en un período que se extiende desde fines del siglo XIX hasta principios del siglo XX. La actividad azucarera demostró tempranamente la necesidad de contar con una mano de obra disciplinada y para lograrlo fue importante el respaldo de los poderes públicos a través del diseño de un marco legal que respaldaba las estrategias desplegadas por las fábricas y cañeros para asegurar ese objetivo. A la par de esta legislación coercitiva, los industriales tucumanos otorgaban también una serie de beneficios como vivienda, seguros, asistencia médica primaria y educación. Es decir, que desde temprano las prácticas coactivas se combinaron con asistencialismo, y resulta de interés ofrecer alguna clave explicativa del sentido de estas acciones. Las diferencias existentes entre los ingenios, se traducían en marcadas desigualdades en los beneficios que recibían los trabajadores, pero sin duda era la pertenencia a la fábrica en calidad de trabajador lo que aseguraba la vivienda, la ración y la atención médica y por lo tanto pérdida del puesto laboral no sólo implicaba la pérdida del salario sino también del lugar de residencia y el acceso a los beneficios.

Las tropas egipcias dependían de los carros y de la infantería que esencialmente luchaba con hachas, espadas cortas, espadas de hoz, jabalinas, mazas, venablos, hondas y se defendían con escudos. El uso de cascos, cotas de placas de bronce se extendió con rapidez y los mercenarios shardana introdujeron las espadas largas. Con la crisis política a finales de la dinastía XIX, y la pérdida de territorios a inicios de la dinastía del XX, el ejército perdió también parte de sus recursos y los artesanos asiáticos especializados en la metalurgia.The army of Seti I and Ramses II, which fought against the hittites, possessed the most modem weapons of that era. The Egyptian troops depended upon chariots and infantry which essentially fought with axes, short swords, sickle swords, spears, javelins, lances, self and composite bows and who defended themselves with shields. The use of helmets and coats of mail became more and more widespread and the shardana mercenaries introduced long swords. With the political crisis at the end of the XIXth.

  6. Electron diffraction on amorphous and crystalline AuAl2 , AuGa2 and AuIn2 thin films

    Bohorquez, A.

    1991-01-01

    Experimental (in situ) measurements of electron diffraction and resistivity of amorphous and crystalline AuAl 2 , AuGa 2 and AuIn 2 thin films were performed. Thin films were produced by quench condensation. Interference and atomic distribution functions were analyzed assuming the same short range order for the three systems in the amorphous phase. The experimental results do not agree with this assumption, giving evidence that the short range order is not the same for the three amorphous systems. Further discussion of interference and atomic distribution functions shows a more evident tendency in amorphous AuIn 2 where short order of AuIn 2 and In can be inferred. (Author)

    Highlights: • Fe–Au–B–N forms a good model alloy system for self healing of deformation damage. • Solute Au atoms exclusively precipitate at grain boundaries, cracks and cavities. • XPS indicates a strong tendency for Au segregation on free surfaces at 550 °C. • Interstitial B and N form hexagonal BN on free surfaces at 550 °C. • Selective Au precipitation at open volume defects can cause autonomous repair. -- Abstract: The influence of deformation-induced defects on the isothermal precipitation of Au was studied in high-purity Fe–Au and Fe–Au–B–N alloys. Preferential Au precipitation upon annealing at 550 °C is observed at local plastic indentations. In fractured Fe–Au–B–N, solute Au atoms were found to heterogeneously precipitate at grain boundaries and local micro-cracks. This is supported by in-situ creep tests that showed a strong tendency for Au precipitation at cracks and cavities also formed during creep loading at 550 °C. Complementary X-ray photoelectron spectroscopy experiments indicate a strong tendency of Au, B and N segregation onto free surface during aging. The observed site-specific precipitation of Au holds interesting opportunities for defect healing in steels subjected to creep deformation.

    Conductive Au-biopolymer composites have promising applications in tissue engineering such as nerve tissue regeneration. In this study, silk fibroin nanofibers were formed in aqueous solution by regulating silk self-assembly process and then used as template for Au nanowire fabrication. We performed the synthesis of Au seeds by repeating the seeding cycles for several times in order to increase the density of Au seeds on the nanofibers. After electroless plating, densely decorated Au seeds grew into irregularly shaped particles following silk nanofiber to fill the gaps between particles and finally form uniform continuous nanowires. The conductive property of the Au-silk fibroin nanowires was studied with current-voltage ( I-V) measurement. A typical ohmic behavior was observed, which highlighted their potential applications in nerve tissue regeneration.

    Au-Si and Au-Ge alloy systems have a deep eutectic point in the Au-rich concentration region where the melting point falls down to 633 K. In order to investigate the liquid structure in relation to the glass-forming tendency of these alloys, high-energy X-ray diffraction measurements have been carried out at the eutectic composition and at compositions with excess amounts of Au or IVb element. The nearest neighbor correlations in the eutectic liquids are intense and sharp in the pair distribution function and exhibit a rather small temperature dependence in comparison with those alloys of other than the eutectic composition. Structural models for these liquid alloys are proposed with the aid of reverse Monte Carlo simulation. The reproduced atomic arrangements around the eutectic region exhibit a substitutional-type structure where the dense random packing of Au atoms is preserved and Si or Ge atoms occupy the Au-sites at random.

    2002-01-01

    We present results on the magnetoresistance and temperature dependence of the resistivity for nanostructured Au produced by chemical means. The magnetoresistance was typical of highly disordered metals exhibiting quantum interference effects. We fitted the data and were able to determine the spin-orbit scattering relaxation time to be 10 sup - sup 1 sup 2 s and we found the inelastic scattering time at 10 K to be 10 sup - sup 1 sup 1 s. The inelastic scattering rate varied as T sup 3 between 4 and 20 K, which is typical for electron-phonon scattering in disordered metals.

    We have performed numerical optimization of hybrid c-Si/Au nanoantenna's geometry to improve efficiency of NV-centers radiation. We have shown that Purcell factor at the wavelength 635 nm can be as much as 4550 for point light emitter placed in the gap between gold spherical nanoparticle and truncated silicon nanocone. We have demonstrated that electric field enhancement can reach a value of 12.9 at the wavelength of NV-center pumping, 532 nm. Our results can be useful for the development of more efficient sources of single photons based on NV-centers in nanodiamonds.

  15. Electrochemical Properties of Alkanethiol Monolayers Adsorbed on Nanoporous Au Surfaces

    International Nuclear Information System (INIS)

    Chu, Yeon Yi; Seo, Bora; Kim, Jong Won

    2010-01-01

    We investigated the electrochemical properties of alkanethiol monolayers adsorbed on NPG surfaces by cyclic voltammetry and electrochemical impedance spectroscopy, and the results are compared to those on flat Au surfaces. The reductive desorption of alkanethiols on NPG surfaces is observed in more negative potential regions than that on flat Au surfaces due the stronger S-Au interaction on NPG surfaces. While the electron transfer through alkanethiol monolayers on flat Au surfaces occurs via a tunneling process through the monolayer films, the redox species can permeate through the monolayers on NPG surfaces to transfer the electrons to the Au surfaces. The results presented here will help to elucidate the intrinsic electrochemical properties of alkanethiol monolayers adsorbed on curved Au surfaces, particularly on the surface of AuNPs. Self-assembled monolayers (SAMs) of thiolate molecules on Au surfaces have been the subject of intensive research for the last few decades due to their unique physical and chemical properties. The well-organized surface structures of thiolate SAMs with various end-group functionalities can be further utilized for many applications in biology and nanotechnology. In addition to the practical applications, SAMs of thiolate molecules on Au surfaces also provide unique opportunities to address fundamental issues in surface chemistry such as self-organized surface structures, electron transfer behaviors, and moleculesubstrate interactions. Although there have been numerous reports on the fundamental physical and chemical properties of thiolate SAMs on Au surfaces, most of them were investigated on flat Au surfaces, typically on well-defined Au(111) surfaces

    We investigate the atomic and electronic structure of a single layer of pentacene on the Au(111) surface using density functional theory. To find the candidate structures we strain match the pentacene crystal geometry with the Au(111) surface, in this way we find pentacene overlayer structures with a low strain. We show that the geometries obtained with this approach has lower energy than previous proposed surface geometries of pentacene on Au(111). We also show that the geometry and workfunc...

    Ultraviolet photoelectron spectroscopy is used to investigate the energy level alignment and molecular orientation at the interfaces in Au/pentacene/PTCDA trilayer stacks. We deduced a standing orientation for pentacene grown on Au while we conclude a flat lying geometry for PTCDA grown onto pentacene. We propose that the rough surface of polycrystalline Au induces the standing geometry in pentacene. It is further shown that in situ deposition of PTCDA on pentacene can influence the orientati...

  19. Magnetic holes in the solar wind between 0.3 AU and 17 AU

    2000-01-01

    Full Text Available Magnetic holes (MHs are depressions of the magnetic field magnitude. Turner et al. (1977 identified the first MHs in the solar wind and determined an occurrence rate of 1.5 MHs/d. Winterhalter et al. (1994 developed an automatic identification criterion to search for MHs in Ulysses data in the solar wind between 1 AU and 5.4 AU. We adopt their criterion to expand the search to the heliocentric distances down to 0.3 AU using data from Helios 1 and 2 and up to 17 AU using data from Voyager 2. We relate our observations to two theoretical approaches which describe the so-called linear MHs in which the magnetic vector varies in magnitude rather than direction. Therefore we focus on such linear MHs with a directional change less than 10º. With our observations of about 850 MHs we present the following results: Approximately 30% of all the identified MHs are linear. The maximum angle between the initial magnetic field vector and any vector inside the MH is 20º in average and shows a weak relation to the depth of the MHs. The angle between the initial magnetic field and the minimum variance direction of those structures is large and very probably close to 90º. The MHs are placed in a high β environment even though the average solar wind shows a smaller β. The widths decrease from about 50 proton inertial length in a region between 0.3 AU and 0.4 AU heliocentric distance to about 15 proton inertial length at distances larger than 10 AU. This quantity is correlated with the β of the MH environments with respect to the heliocentric distance. There is a clear preference for the occurrence of depressions instead of compressions. We discuss these results with regard to the main theories of MHs, the mirror instability and the alternative soliton approach. Although our observational results are more consistent with the soliton theory we favour a combination of both. MHs might be the remnants of initial mirror mode structures which can be described as

    Thin films of TiO 2 were doped with Au by ion implantation and in situ during the deposition. The films were grown by reactive magnetron sputtering and deposited in silicon and glass substrates at a temperature around 150 °C. The undoped films were implanted with Au fluences in the range of 5 × 10 15 Au/cm 2 –1 × 10 17 Au/cm 2 with a energy of 150 keV. At a fluence of 5 × 10 16 Au/cm 2 the formation of Au nanoclusters in the films is observed during the implantation at room temperature. The clustering process starts to occur during the implantation where XRD estimates the presence of 3–5 nm precipitates. After annealing in a reducing atmosphere, the small precipitates coalesce into larger ones following an Ostwald ripening mechanism. In situ XRD studies reveal that Au atoms start to coalesce at 350 °C, reaching the precipitates dimensions larger than 40 nm at 600 °C. Annealing above 700 °C promotes drastic changes in the Au profile of in situ doped films with the formation of two Au rich regions at the interface and surface respectively. The optical properties reveal the presence of a broad band centered at 550 nm related to the plasmon resonance of gold particles visible in AFM maps.

  2. Carbon monoxide oxidation on bimetallic Ru/Au(111 surfaces

    Full Text Available The electrochemical deposition of Ru on Au(111 was performed in 0.5 M H2SO4+10-4 M RuCl3 . The obtained bimetallic Ru/Au(111 surfaces were character-ised by cyclic voltammetry and in situ STM in 0.5 MH2SO4. The Ru deposit consists of nanoscale islands, which merge with increasing coverage. Two different types of bimetallic Ru/Au(111 surfaces with respect to the distribution of Ru islands over the Au(111 substrate surface were obtained. When the deposition was performed at potentials more positive than the range of Au(111 reconstruction, homogeneous nucleation occured resulting in a random distribution of Ru islands. When the deposition was performed on reconstructed Au(111 at low overpotentials, selective nucleation occured resulting in the replication of the Au(111 reconstruction. Only at higher deposition overpotentials, can multilayer deposits be formed, which exhibit a very rough surface morphology. The electrocatalytic activity of such structurally well defined Ru/Au(111 bimetallic surfaces was studied towards CO oxidation with the Ru coverage ranging from submonolayer to several monolayer. COstripping commences at about 0.2 Vand occurs over a broad potential range. The observed influence of the Ru structure on the CO stripping voltammetry is explained by local variations in the COadsorption energy, caused by differences in the local Ru structure and by effects induced by the Au(111 substrate.

    We report the first measurement of charmed-hadron (D0) production via the hadronic decay channel (D0→K-+π+) in Au +Au collisions at √sNN =200 GeV with the STAR experiment. The charm production cross section per nucleon-nucleon collision at midrapidity scales with the number of binary collisions, Nbin, from p +p to central Au +Au collisions. The D0 meson yields in central Au +Au collisions are strongly suppressed compared to those in p+p scaled by Nbin, for transverse momenta pT>3 GeV /c, demonstrating significant energy loss of charm quarks in the hot and dense medium. An enhancement at intermediate pT is also observed. Model calculations including strong charm-medium interactions and coalescence hadronization describe our measurements.

    En 50 ans d'indépendance, le sport camerounais a beaucoup évolué. De 11 en 1970, les fédérations sportives sont passées à plus de 40 aujourd'hui et les titres, trophées et médailles ne se comptent plus depuis lors. Le Cameroun est devenu progressivement une nation où le sport compte et où l'exploit sportif n'est plus méprisé, rejeté, voire vilipendé. Hier assimilés à des brutes épaisses, les sportifs sont aujourd'hui admirés et adulés. Finie l'image négative de marginaux qui leur collait au corps : finis les sous-entendus ridicules où ils étaient classés au bas de l'échelle sociale, juste bons pour bander les muscles et réaliser des performances. C'est cela la plus grande victoire du sport camerounais en 50 ans d'existence. Il a réussi à faire l'unanimité et les performances des sportifs devenues pour toute la nation un modèle, une référence et un réel motif de fierté.

    Full Text Available El siguiente artículo analiza a las prácticas corporales -la educación física escolar, las gimnasias, los juegos, los bailes, los paseos, las caminatas y ciertos sports- en la Argentina a finales del siglo XIX como un terreno conflictivo en el que distintos actores y grupos sociales pusieron en circulación, distribución, transmisión y producción un conjunto complejo y heterogéneo de tópicos vinculados con el cuerpo y su funcionamiento, la salud y la enfermedad, la diferencia sexual y la feminidad. Centramos la atención, desde el discurso médico, en una de las enfermedades más mencionadas en la época: la histeria. Asimismo, analizamos el significado que tuvo la salud para las niñas y mujeres que experimentaron la práctica de la gimnasia y de los diferentes ejercicios físicos prescriptos. El interrogante central es: ¿cómo y por qué el registro médico conceptualizó el par salud/enfermedad en las niñas y mujeres en el marco de ciertas prácticas corporales?The following article analyzes the body practices - the school physical education, gymnastics, games, dances, rides, walks and certain sports - in Argentina at the end of the nineteenth century- as a conflictive field where different actors and social groups spread, distributed, transmitted and produced a complex and heterogeneous group of topics linked to the body and its functioning, health and illness, sexual difference and femininity. From a medical point of view, we drew our attention on one of the most commonly mentioned illnesses more at that time: hysteria. We also analyzed the meaning of health for the girls and women that experienced the practice of gymnastics and different prescribed physical exercises. The main question is: how and why did the medical recordconceptualize both health and illness/ in the frame of certain body practices for girls and women?

    Nanocomposite thin films consisting of a dielectric matrix, such as titanium oxide (TiO{sub 2}), with embedded gold (Au) nanoparticles were prepared and will be analysed and discussed in detail in the present work. The evolution of morphological and structural features was studied for a wide range of Au concentrations and for annealing treatments in air, for temperatures ranging from 200 to 800 °C. Major findings revealed that for low Au atomic concentrations (at.%), there are only traces of clustering, and just for relatively high annealing temperatures, T ≥ 500 °C. Furthermore, the number of Au nanoparticles is extremely low, even for the highest annealing temperature, T = 800 °C. It is noteworthy that the TiO{sub 2} matrix also crystallizes in the anatase phase for annealing temperatures above 300 °C. For intermediate Au contents (5 at.% ≤ C{sub Au} ≤ 15 at.%), the formation of gold nanoclusters was much more evident, beginning at lower annealing temperatures (T ≥ 200 °C) with sizes ranging from 2 to 25 nm as the temperature increased. A change in the matrix crystallization from anatase to rutile was also observed in this intermediate range of compositions. For the highest Au concentrations (> 20 at.%), the films tended to form relatively larger clusters, with sizes above 20 nm (for T ≥ 400 °C). It is demonstrated that the structural and morphological characteristics of the films are strongly affected by the annealing temperature, as well as by the particular amounts, size and distribution of the Au nanoparticles dispersed in the TiO{sub 2} matrix. - Highlights: • Au:TiO{sub 2} films were produced by magnetron sputtering and post-deposition annealing. • The Au concentration in the films increases with the Au pellet area. • Annealing induced microstructural changes in the films. • The nanoparticle size evolution with temperature depends on the Au concentration.

  9. Hollow Au@Pd and Au@Pt core-shell nanoparticles as electrocatalysts for ethanol oxidation reactions

    Hybrid alloys among gold, palladium and platinum become a new category of catalysts primarily due to their enhanced catalytic effects. Enhancement means not only their effectiveness, but also their uniqueness as catalysts for the reactions that individual metals may not catalyze. Here, preparation of hollow Au@Pd and Au@Pt core-shell nanoparticles (NPs) and their use as electrocatalysts are reported. Galvanic displacement with Ag NPs is used to obtain hollow NPs, and higher reduction potential of Au compared to Ag, Pd, and Pt helps to produce hollow Au cores first, followed by Pd or Pt shell growth. Continuous and highly crystalline shell growth was observed in Au@Pd core-shell NPs, but the sporadic and porous-like structure was observed in Au@Pt core-shell NPs. Along with hollow core-shell NPs, hollow porous Pt and hollow Au NPs are also prepared from Ag seed NPs. Twin boundaries which are typically observed in large size (>20 nm) Au NPs were not observed in hollow Au NPs. This absence is believed to be due to the role of the hollows, which significantly reduce the strain energy of edges where the two lattice planes meet. In ethanol oxidation reactions in alkaline medium, hollow Au@Pd core-shell NPs show highest current density in forward scan. Hollow Au@Pt core-shell NPs maintain better catalytic activities than metallic Pt, which is thought to be due to the better crystallinity of Pt shells as well as the alloy effect of Au cores. © 2012 The Royal Society of Chemistry.

    In this paper, the behaviour of polycrystalline Au, Au-Cu (Cu 25%) and Au-Ag-Cu (Ag 10%, Cu 15%) electrodes in contact with neutral aqueous solutions of KCN has been studied as a function of potential by means of in situ sum frequency generation (SFG) and difference frequency generation (DFG) spectroscopies. The potential-dependent spectra have been analysed quantitatively with a model for the second-order non-linear susceptibility accounting for vibrational and electronic effects. The potential-dependence of the CN - stretching band position and of the free-electron contribution to the real part of the non-resonant component of the second-order susceptibility have been accounted for. Spectroelectrochemical results were complemented by cyclic voltammetric measurements. The chief stress in this work has been placed on systematising and quantifying the interaction between the vibrational and electronic structures of the electrodic interfaces studied. The effects of adsorbates on the electronic structure of the adsorbing electrode, as a function of electrode alloy composition and applied potential are particularly critical for the understanding of Au-alloy electrochemistry in the presence of cyanide and cyanocomplexes. The systematic comparison of SFG and DFG spectra measured under the same electrochemical conditions for Au, Au-Cu and Au-Ag-Cu electrodes discloses a rich phenomenology related to the electronic structure of the interface

    Full Text Available Cette analyse a pour but d’exposer la manière dont Flaubert récupère les stéréotypes présents dans les physiologies, genre littéraire à la mode dans la première moitié du XIXe siècle, en définissant leurs différentes modalités d’insertion dans Bouvard et Pécuchet. Après s’être interrogée sur le statut particulier des physiologies, l’étude montre que les différents types qu’elles mettent en scène, et plus particulièrement celui du « bourgeois », fournissent à Flaubert un matériel discursif stéréotypé qui lui sert de base de composition à l’ensemble de son texte : composition des personnages (traits physiques, caractériels, axiologiques, etc., composition structurelle du roman, etc. La démonstration attire ainsi l’attention sur ce qui paraît être l’une des lignes de force de l’écriture flaubertienne : l’amenuisement au sein de l’espace romanesque du langage de l’auteur au profit d’un langage stéréotypé, venu d’ailleurs.

    Uniform PbS-Au nanostar-nanoparticle heterodimers consisting of one Au nanoparticle grown on one horn of a well-defined six-horn PbS nanostar were prepared using the PbS nanostars as growth substrates for the selective deposition of Au nanoparticles. The size of the Au nanoparticles on the horns of the PbS nanostars could be readily adjusted by changing the PbS concentration for the deposition of Au nanoparticles. An optimum cetyltrimethylammonium bromide concentration and temperature were essential for the selective deposition of uniform Au nanoparticles on single horns of the PbS nanostars. Unusual PbS-Au nanoframe-nanoparticle heterodimers were obtained by etching the PbS-Au nanostar-nanoparticle heterodimers with oxalic acid while novel cap-like Au nanoparticles were obtained by etching with hydrochloric acid. The obtained heterodimeric nanostructures and cap-like nanoparticles are promising candidates for anisotropic nanoscale building blocks for the controllable assembly of useful, complex architectures.

    Au/SiO 2 nanocomposite films consisting of an extremely high number density of Au nanoparticles dispersed in a SiO 2 matrix a few nanometres thick were deposited by a co-sputtering method, and employed for molecular conductance measurement by immobilizing and bridging conjugated biphenyl molecules on dispersed Au nanoparticles. The number density of Au nanoparticles in the insulating SiO 2 matrix was approximately 14 000 μm 2 , and the average interparticle distance from their neighbours was about 8 nm. The current increased considerably up to the range of nanoamperes after the immobilization of the conjugated biphenyl molecules, 10 5 times larger than without molecules before immobilization. Although the Au nanoparticles can be connected to only 30% of all combinations of neighbouring Au nanoparticles by biphenyl molecules 2.4 nm long from the topological analysis, the biphenyl molecules can bridge most of the Au nanoparticles, and their bridging continuity is over 100 nm in length. Thus the measured current is suggested to come from the continuously bridged molecules between the Au nanoparticles. Furthermore the I-V data of the whole Au/SiO 2 nanocomposite film immobilized with conjugated molecules are confirmed to be in a reasonable range in comparison with the scanning tunnelling spectroscopy data of similar conjugated molecules

    We report the measurements of Sigma(1385) and Lambda(1520) production in p+p and Au+Au collisions at sqrt[s{NN}]=200 GeV from the STAR Collaboration. The yields and the p(T) spectra are presented and discussed in terms of chemical and thermal freeze-out conditions and compared to model predictions. Thermal and microscopic models do not adequately describe the yields of all the resonances produced in central Au+Au collisions. Our results indicate that there may be a time span between chemical and thermal freeze-out during which elastic hadronic interactions occur.

  16. Correlated Production of Protons and Antiprotons in Au + Au Collisions at sqrt(sNN) = 200 GeV

    2007-01-01

    Correlations between p and (anti p) at transverse momenta typical of enhanced baryon production in Au + Au collisions are reported. The PHENIX experiment has measured same and opposite sign baryon pairs in Au + Au collisions at √(ovr S NN ) = 200 GeV. Correlated production of proton and (anti p) with the trigger particle from the range 2.5 T T T range rises with increasing centrality, except for the most central collisions, where baryons show a significantly smaller number of associated mesons. These data are consistent with a picture in which hard scattered partons produce correlated p and (anti p) in the p T region of the baryon excess.

    Partonic effects on two-particle transverse momentum correlations are studied for Au + Au collisions at √S NN =130 GeV in the Monte Carlo model, AMPT. This study demonstrates that in these collisions partonic interactions contribute significantly to the correlations. Additionally, model calculations are compared with data of the two-particle transverse momentum correlations measured by the STAR Collaboration at RHIC, and it is found that AMPT with string melting can well reproduce the measured centrality dependence of the two-particle transverse momentum correlations in Au + Au collisions at √S NN =130 GeV.

    The resonance production in Au+Au, d+Au and p+p collisions at √(s) = 200 AGeV are presented. The resonances are used as a sensitive tool to examine the collision dynamics in the hadronic medium through their decay and regeneration. The modification of resonance mass, width, and shape due to phase space and dynamical effects are also discussed. The measurement of resonances provides an important tool for studying the dynamics in relativistic heavy-ion collisions by probing the time evolution of the source from chemical to kinetic freeze-out and the hadronic interactions at later stages

  20. Growth and structure of Co/Au magnetic thin films

    1999-01-01

    We have studied the growth and the crystallographic structure of magnetic ultra thin cobalt/gold films (Co/Au), in order to investigate the correlations between their magnetic and structural properties. Room temperature (R.T.) Co growth on Au (111) proceeds in three stages. Up to 2 Co monolayers (ML), a bilayer island growth mode is observed. Between 2 and 5 ML, coalescence of the islands occurs, covering the substrate surface and a Co/Au mixing is observed resulting from the de-construction of the Herringbone reconstruction. Finally, beyond 5 ML, the CoAu mixing is buried and the Co growth continues in a 3-D growth. Annealing studies at 600 K on this system show a smoothing effect of the Co film, and at the same time, segregation of Au atoms. The quality of the Co/Au interface (sharpness) is not enhanced by the annealing. The local order was studied by SEXAFS and the long range order by GIXRD showing that the Co film has a hexagonal close packed structure, with an easy magnetization axis perpendicular to the surface. From a local order point of view, the Co grows with an incoherent epitaxy and keeps its own bulk parameters. The GIXRD analysis shows a residual strain in the Co film of 4%. The difference observed between the local order analysis and the long range order results is explained in terms of the low dimensions of the diffracting domains. The evolution of film strains, as a function of the Co coverage, shows a marked deviation from the elastic strain theory. Modification of the strain field in the Co film as a function of the Au coverage is studied by GIXRD analysis. The Au growth study, at R.T., shows no evidence of a Au/Co mixing in the case of the Au/Co interface. The Au overlayer adopts a twinned face centred cubic structure on the rough Co film surface.

    Full Text Available Déclassée en tant que « place forte » en 1925, Grenoble voit son développement urbain conditionné en grande partie par la libération des emprises militaires. Considérées initialement comme de simples réserves foncières, ces structures militaires ont été progressivement investies d’une valeur patrimoniale qui marque fortement certaines opérations d’aménagement urbain et paysager. À travers l’exemple grenoblois, nous évaluerons l’impact des aménagements militaires du XVIIe au XIXe siècle sur l’urbanisme du XXe siècle et dresserons une cartographie urbaine de ce patrimoine militaire en constitution.Grenoble ceased to be qualified as 'place forte' [fortified town] in 1925, and the town's subsequent urban development was largely conditioned by the availability of former military properties. Considered at first as simple real estate opportunities, these military structures were gradually invested with historical and cultural values which feature strongly in certain operations of urban development and landscaping. Starting out from this example at Grenoble, we will try to assess the impact of military installations of the seventeenth to nineteenth centuries on the town-planning of the twentieth century and will map this now recognised heritage in its urban context.

    Full Text Available La provincia de Atacama constituyó uno de los escenarios de transformación económica más dinámicos del siglo XIX. En ese marco este trabajo sintetiza las transformaciones operadas en la industria minera del cobre en la segunda mitad del siglo XIX, centrando su enfoque sobre los factores de inestabilidad generados por los ciclos cortos de recesión económica y la sensibilidad de los productores locales frente a los cambios operados en el mercado internacional. Al mismo tiempo, se analiza la posición del gremio minero en algunas de esas coyunturas negativas y su particular visión en torno a los problemas relativos al mercado laboral, a las dificultades de transporte, la competencia externa y la política tributaria aplicada por el Estado chileno. El trabajo enfatiza la distinta intensidad con que se manifiestan estos ciclos recesivos entre los actores productivos locales, lo que a su vez profundiza los procesos de diferenciación económica en aquella región minera.

El estudio de estos hechos criminales judicializados en la 2ª Circunscripción Judicial de la provincia de Santa Fe revela que, si bien la condena establecida por ley era la pena de muerte, en la mayoría de los casos existió algún elemento procesal o se consideró alguna circunstancia que determinó una reducción, o absolución, de esta condena. Esto fue un rasgo importante en la definición de la práctica judicial en el proceso de profesionalización de la justicia conocido por la sociedad rosarina del siglo XIX.

    Full Text Available This article analyzes, from the perspective of the intellectual history, the laicism process during the nineteenth century in Hispanic America, focusing on the eschatological reading on the part of certain Catholic intellectuals. The argument is that eschatological thought must be understood beyond its theological dimensions, considering it as an apocalyptic reading of the social and cultural changes that political modernity brought about for religion and its role in the public sphere during the 19th Century.El artículo examina, desde la perspectiva de la historia intelectual, el análisis del proceso de laicidad en el siglo XIX iberoamericano, y su lectura en clave escatológica desde algunos sectores de la intelectualidad católica. El texto argumenta que este pensamiento escatológico debe ser estudiado más allá de sus dimensiones teológicas, sino también como una forma particular de leer apocalípticamente los cambios sociales y culturales que la modernidad política implicó para la religión y su lugar en el espacio público en el siglo XIX.

    Full Text Available El objetivo del artículo es señalar los principales problemas metodológicos a los que se enfrentan los estudios de historia demográfica de Jalisco durante el siglo XIX. Se reconocen tres desafíos susceptibles de condicionar las metas del análisis. El primero es teórico; el texto argumenta sobre la importancia de contextualizar la discusión dentro de un marco conceptual que aporte evidencias empíricas. Se retoma el papel que juega la población en el desempeño económico, especialmente, en el proceso de industrialización. El segundo desafío lo constituyen las fuentes, ¿son éstas congruentes para realizar un estudio sistematizado del crecimiento poblacional a través del tiempo? Finalmente, influyen las hipótesis preestablecidas al respecto, las cuales dan respuestas concretas, pero simultáneamente abren la posibilidad a una gama amplia de preguntas. El trabajo concluye que ninguno de los desafíos mencionados es suficientemente poderoso para impedir un estudio serio y sistemático del comportamiento demográfico en Jalisco durante el siglo XIX.

    Full Text Available El artículo analiza la participación de los productos de recolección -miel, cera, grana y sobre todo algarroba- en la economía campesina de Santiago del Estero desde la conquista hasta fines del siglo XIX. Entre otras variables, se analiza el peso que históricamente tuvieron las condiciones ambientales, la competencia con otros grupos por los mismos recursos, la combinación con otras actividades campesinas y las estrategias migratorias en el patrón de subsistencia de las comunidades de los ríos Dulce y Salado. Por fin, la segunda parte se concentra en los recolectores. Se intenta reconstruir el perfil tipo de estos sujetos pensados por la literatura de los siglos XIX y XX de dos maneras opuestas: como hijos ociosos de la abundancia de los recursos del monte o bien como víctimas de la escasez de un ambiente hostil

    Full Text Available La irrupción de las mujeres en la Escuela, como alumnas y como enseñantes, comenzó muy tímidamente en la España del siglo XVIII, si bien no fue hasta finales del siglo XIX, con la Ley Moyano (1857, cuando se estableció la obligatoriedad de la instrucción primaria pública para las niñas. Pero las políticas educativas no sólo posibilitaron progresivamente la incorporación y la permanencia de las niñas en la institución escolar. También se hizo efectivo el ingreso de las mujeres en la profesión docente, ingreso que en un principio quedaba reducido a la enseñanza primaria y que respondía más a una cuestión de utilidad que a un interés social por darles a las mujeres la oportunidad de mejorar su formación para su incorporación al mercado laboral. En este trabajo nos proponemos analizar la trayectoria de la formación inicial de las maestras españolas, diseñada según el programa curricular concretado en diferentes planes de estudio a lo largo del siglo XIX.

    Sarmiento believed that Copernican astronomy was one of the critical scientific disciplines to the formation of a "modern" citizen. In this work, we shall study astronomical science from two points of view: from the scientific knowledge and the educational presentation of such knowledge. Our study will address in Argentina in 19th century, starting from the initiative of Bernardino Rivadavia in 1821, who founded an astronomic observatory at Buenos Aires, until the first activities of the observatories at Córdoba and La Plata. On both lines, scientific and educative, we shall analyze the influence of positivist ideas. We shall highlight epistemological differences between both observatories, Córdoba's based on French positivism and La Plata's based on German positivism. We shall also show the different attitude of both observatories towards education. We shall see the way in which positivist ideas had great relevance in the training of elementary school teachers. We shall also establish the relevant influence of the socio-historical context over the astronomical development, and show that astronomy was a fundamental social factor at Argentina history. Domingo F. Sarmiento consideraba que la astronomía copernicana era una de las disciplinas científicas fundamentales para la conformación de un ciudadano "moderno". En este trabajo estudiaremos la ciencia astronómica desde dos vertientes: la referida específicamente al conocimiento científico y aquella vinculada con la presentación educativa de dicho conocimiento. Nuestro estudio se desarrollará en Argentina durante el siglo XIX, desde la iniciativa de Bernardino Rivadavia en 1821, de establecer en Buenos Aires un observatorio astronómico, hasta las primeras actividades de los observatorios de Córdoba y de La Plata.

    Full Text Available In this article the structural behavior of a timber- framed wall is analysed. The wall is composed by a timber grid of vertical parts (posts and horizontal elements (beams, whose panels are normally filled with plaster rubble. This system was widely used as a load-bearing wall system in the Spanish residential buildings between the 17th and 19th centuries. The research concludes that the loads are transmitted mainly through the infills by vertical compression, and that the deformation of the beams by bending is negligible, except in those cases in which there is no infill at the bottom. Also, using numerical simulation by finite elements, a formula determining the percentage of total loads absorbed by posts and infills is obtained depending on their rigidity to compression, so as to quantify the stress state of them. This is a fundamental aspect in the design and dimensioning of reinforcements in structural rehabilitation.En este artículo se analiza el comportamiento estructural del muro entramado de madera. Muro compuesto de una retícula de piezas verticales (pies derechos y horizontales (carreras, cuyos cuarteles se rellenan normalmente con yesones. Este sistema es ampliamente utilizado como muro portante en la edificación residencial española entre los siglos XVII y XIX. Del análisis, se concluye que las cargas se transmiten principalmente a través de los rellenos por compresión vertical, y que la colaboración de las carreras por flexión es despreciable, salvo en aquellos casos en los que no exista el relleno del cuartel inferior. Además, mediante la simulación numérica por elementos finitos, se obtiene una expresión que determina el porcentaje de carga total que absorben los pies derechos y los rellenos en función de sus rigideces a compresión, con el objeto de cuantificar el estado tensional de los mismos, aspecto fundamental en el diseño y dimensionamiento de refuerzos en rehabilitación estructural.

    Full Text Available El artículo aborda los orígenes, las andanzas y el ocaso de una organización criminal boliviana denominada “la cuadrilla de Punata”: un clan familiar que trabajaba para los gobiernos conservadores de fines del siglo XIX mediante redes clientelares de las que formaban parte no pocos policías. En un momento la banda puso en jaque al gobierno de Severo Fernández Alonso y se convirtió en un asunto de Estado, pese a lo cual esta organización jamás ha sido investigada y su historia permaneció hasta hoy sepultada en los archivos. Por otra parte, a través de la saga de la cuadrilla de Punata pueden conocerse un conjunto de temas inexplorados en la historiografía cochabambina: los nexos entre el crimen, la política y el poder policial, el tratamiento periodístico de la delincuencia y las pugnas entre liberales y conservadores en la antesala de la Guerra Federal. Finalmente el artículo propone también una interpretación original del fenómeno del bandolerismo político.   This article discusses the origins, undertakings and decline of a Bolivian criminal organization called the "Punata Gang": a family clan that worked for the conservative governments of the late nineteenth century through patronage networks, of which more than a few policemen partook. At one point, the gang threatened the government of Severo Fernández Alonso and the issue became a State affair. In spite of that, the organization was never investigated and its history has remained until today buried in the archives. Moreover, by looking at the Punata Gang’s saga this paper addresses a series of topics yet to be explored in the Cochabamba historiography: the relation between crime, politics and police power; the press coverage of delinquency; and the conflicts between liberals and conservatives on the verge of the Federal War. Finally, this article further proposes an original interpretation of the phenomenon of political banditry.

    Full Text Available Problem Setting. The article describes the activities of the zemstvo self-government which had a significant impact on the process of national constitutionalism development in the late XIX – early XX centuries. The actuality of the topic. Zemstvo self-government got significant practical experience of legal oppositional activity, which is an important element of constitutionalism. Within the territory of ethnicUkraine, zemstvo constitutionalism combined two components: All-Russian and national. The purpose of the article. All-Russian zemstvo constitutionalism had features of legal, semi-legal and illegal activities, which were represented by liberal and radical wing of zemstvo liberal-democratic movement respectively. In the All-Russian context, zemstvo radicals advocated the idea of establishing constitutional order in the Russian Empire, which involved constitutional recognition of democratic rights and freedoms, equality, parliamentary system and establishment of a constitutional monarchy, decentralization of power, political pluralism. The national component of zemstvo constitutionalism, which was formed at the beginning of the bourgeois-democratic revolution of 1905–1907, had illegal character and its essence can be described by the fact that some zemstvo liberals insisted on the need to restore the Ukrainian state in the form of autonomy within democratic Russia. Representatives of both components of zemstvo constitutionalism aimed to implement their constitutional ideas through reforms. Zemstvo constitutionalism reached its highest peak at the beginning of the bourgeois-democratic revolution of 1905–1907. In early XX century zemstvo liberals took active part in activities of bourgeois-democratic political parties. Development of Russian and Ukrainian political parties led to a split in the radical wing of zemstvo liberal-democratic movement on the national basis. Some zemstvo leaders joined the All-Russian Party of Octobrists and

    Highlights: • PtAu nanoalloy surface is heteroepitaxially grown on the pre-synthesized Au nano-pentagrams. • The PtAu/Au nano-pentagrams exhibit excellent electrocatalytic activity for ethanol oxidation. • The charge transfer resistance of PtAu/Au is lower than that of commercial Pt/C. • The durability and anti-poisoning ability of PtAu/Au is much better than those of commercial Pt/C - Abstract: Improving Pt utilization is of fundamental importance for many significant processes in energy conversion, which is strongly dependent on the surface structure of used catalysts. Based on the traditional Pt-on-Au system which has been proved to be an ideal nanostructure for improving the catalytic activity and stability of Pt, and the recent follow-up studies on this system, we introduce here a new strategy for fabricating Pt surface with high-index facets over the Pt-on-Au system. To achieve this goal, we elaborately designed and fabricated a unique zigzag PtAu alloy nanosurface on Au nano-pentagrams (PtAu/Au NPs) through epitaxial growth of Pt along the high-index facets on the pre-synthesized Au nano-pentagrams. Owing to the surface electronic interaction between Au and Pt and the exposed high-index facets from the unique morphology of zigzag PtAu alloy nanosurface, the as-prepared PtAu/Au NPs exhibited excellent electrocatalytic performance toward ethanol oxidation reaction (EOR) in alkaline condition. The specific activity (8.3 mA cm"−"2) and mass activity (4.4 A mg"−"1) obtained from PtAu/Au NPs are about 5.2 and 5.5 times, respectively, higher than those from commercial Pt/C for EOR.

  16. CO oxidation on Alsbnd Au nano-composite systems

    Using first principles method we report the CO oxidation behaviour of Alsbnd Au nano-composites in three different size ranges: Al6Au8, Al13Au42 and a periodic slab of Alsbnd Au(1 1 1) surface. The clusters prefer enclosed structures with alternating arrangement of Al and Au atoms, maximising Auδ-sbnd Alδ+ bonds. Charge distribution analysis suggests the charge transfer from Al to Au atoms, corroborated by the red shift in the density of states spectrum. Further, CO oxidation on these nano-composite systems was investigated through both Eley - Rideal and Langmuir Hinshelwood mechanism. While, these clusters interact with O2 non-dissociatively with an elongation of the Osbnd O bond, further interaction with CO led to formation of CO2 spontaneously. On contrary, the CO2 evolution by co-adsorption of O2 and CO molecules has a transition state barrier. On the basis of the results it is inferred that nano-composite material of Alsbnd Au shows significant promise toward effective oxidative catalysis.

    Au nanoparticles, which are kept in vacuum after the preparation by gas evaporation method, show ferromagnetism even in 1.7 nm in diameter. The intrinsic magnetism is examined by detecting the disappearance of spontaneous magnetization in Au bulk prepared by heating the nanoparticles without exposure to the air. The temperature dependence of spontaneous magnetization is not monotonic and the increase in magnetization is observed after Au nanoparticles are exposed to the air. The magnetic behavior can be interpreted by the ferrimagnetic-like core–shell structure with shell thickness of 0.16±0.01 nm and magnetic moment of (1.5±0.1)×10{sup −2} μ{sub B}/Au atom, respectively. - Highlights: • Au nanoparticles with clean surface were prepared by the gas evaporation method. • The spontaneous magnetization was observed in Au nanoparticles. • Temperature dependent spontaneous magnetization of smaller Au particles was not monotonic. • The magnetic behavior was interpreted by the ferrimagnetic-like core–shell model. • The shell thickness and the magnetic moment per Au atom were estimated.

    A simple method of alternating voltage-induced electrochemical synthesis has been developed to synthesize highly dispersed colloidal Au nanoicosahedra of 14 ± 3 nm in size. This simple and effective method uses a common transformer to apply a zero-offset alternating voltage to a pair of identical Au electrodes that are immersed in an electrolyte solution containing ligands. The obtained Au nanoicosahedra in this work are among the smallest Au icosahedra synthesized in aqueous solutions. A series of experimental conditions have been studied, such as voltage, the electrolyte identity and concentration, stabilizer identity and concentration, and reaction temperature. The mechanistic study indicates that Au nanoicosahedra are produced on electrode surfaces through an intermediate state of AuO{sub x}. The kinetic rate constant of these Au icosahedra in catalyzing the reduction of 4-nitrophenol with sodium borohydride is found much larger than the literature values of similar Au nanocrystals. In addition, the synthesis of Au–Pd-alloyed NCs has also been attempted.Graphical Abstract.
