Magnetic behavior at low temperature of LaMn1-xMgxO3

Liang, H-W; Chen, Y; Zhang, X-X; Zhang, S-J; Zhang, G-H; Yuan, H-M; Feng, S-H

The substitution of Mn with Mg in LaMn1-xMgxO3 strongly affects the magnetic properties at low temperature and the crystal structure of the LaMn1-xMgxO3 system. Sample displays weak ferromagnetic at low temperature when x≤0.08, and the spin-glass state was observed at low temperature when x≥0.18; th...

Anthocyanins, flavonols, and free radical scavenging activity of Chinese Bayberry (Myrica rubra) extracts and their color properties and stability

Bao, J; Cai, Y; Sun, M; Wang, GY; Corke, H

Characterization of anthocyanins and flavonols and radical scavenging activity assays of extracts from four Chinese bayberry (Myrica rubra) varieties with different fruit colors were carried out. One dominant anthocyanin and three major flavonols were isolated by HPLC, and cyanidin-3-O-glucoside and...

Anomalous I V curve for mono-atomic carbon chains


The electronic transport properties of mono-atomic carbon chains were studied theoretically using a combination of density functional theory and the non-equilibrium Green's functions method. The I–V curves for the chains composed of an even number of atoms and attached to gold electrodes through sul...
