Anomalous scattering study of the bi distribution in the 2212 superconductor: implications for cu valency.

TL;DR: The distribution of the bismuth atoms over the cation sites in the 2212 Bi-Sr-Ca-Cu-O superconductor has been determined by anomalous scattering synchrotron crystallography, and the view that neither extra oxygen nor overlap of thebismuth 6p and copper 3d bands is needed to account for the holes is supported.

Influence of gas pressure on the low-temperature plasma nitriding of surface-nanocrystallined TC4 titanium alloy
Kai Wen,Chengwei Zhang,Yan Gao +2 more
TL;DR: In this paper , the influence of gas pressure on surface nanocrystalline TC4 titanium alloy prepared by shot peening (SP) was investigated, and it was found that 200 Pa was the optimal gas pressure to form more active nitride particles and maintain a high level energy.

Electrochemical insertion of lithium into the Bi2Sr2CaCu2O8+y high-Tc superconductor
TL;DR: The insertion compound LixBi2Sr2CaCu2O8+y (for lithium contents up to the studied level of x=2) was prepared by electro-chemical insertion of lithium into BiSr 2CaCu 2O 8+y pellets at room temperature in galvanic cells using 1.4 M LiAsF6 in 2Me-THF as electrolyte.
