The hole-doped cuprate Bi2-_Pb.Sr 2CulO 6+6 is doped with lead to the solubility limit of x = 0.38 and studied using STM/STS in the overdoped regime where T, < 2K. Despite the high lead content, residual supermodulations are observed in the BiO plane. In agreement with previous studies on (Pb,Bi)-2201, there is no separation of the sample into Pb-rich and Pb-poor domains, nor is there a spectra...

We examine the effect on the superconducting transition temperature (Tc) of chemical inhomogeneities in Bi2Sr2CuO61d and Bi2Sr2CaCu2O81d single crystals. Cation disorder at the Sr crystallographic site is inherent in these materials and strongly affects the value of Tc . Partial substitution of Sr by Ln ~Ln 5 La, Pr, Nd, Sm, Eu, Gd, and Bi! in Bi2Sr1.6Ln0.4CuO61d results in a monotonic decrease...

Fifty nine patients with Helicobacter pylon positive duodenal ulcers that failed to heal after a six week course of treatment with H2 blockers were randomly assigned to one of the following three regimens: (i) bismuth subsalicylate, 600 mg three times daily (n=19), (ii) ranitidine, 300 mg at night (n=20), (iii) bismuth subsalicylate plus ranitidine (n=20). Cumulative ulcer healing rates after f...

Bismuth oxide (Bi2O3) has received great attention as the promising battery-type anode due to its high theoretical capacity and wide operating voltage window, yet slow reaction kinetics poor cyclability are major obstacles affecting performance of energy storage devices. Herein, by employing bismuth-based metal-organic framework (MOF) CAU-17 both template precursor, Bi-Bi2O3 nanoparticles encap...

Uniform bismuth nanospheres were successfully prepared from bismuth nitrate in the presence of poly(N-vinyl-2-pyrrolidone) (PVP) by solvothermal process. The product was characterized by powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy, selected area electron diffraction, and energy-dispersive X-ray. PVP plays a critical role both as a reducing agent and ...

Bismuth oxide directly grown on nickel foam (p-Bi2O3/Ni) was prepared by a facile polymer-assisted solution approach and was used directly as a lithium-ion battery anode for the first time. The Bi2O3 particles were covered with thin carbon layers, forming network-like sheets on the surface of the Ni foam. The binder-free p-Bi2O3/Ni shows superior electrochemical properties with a capacity of 66...

A phase study has been performed of high oxygen ion conducting erbia-stabilized bismuth oxide ( 1 -x)Bi203.xEr203 (BElOOx ) using thermal analysis and X-ray powder diffraction. Investigation of the effect of a long-time (500 h) anneal of samples at 650°C in air revealed that the minimum amount of erbia needed to stabilize the high-temperature cubic 8-Biros phase is 27.5 at%. This boundary value...
