Effect of Pressure-Assisted Heat Treatment on Photoluminescence Emission of α-Bi2O3 Needles
Samara Schmidt,Evaldo Toniolo Kubaski,Diogo P. Volanti,Thiago Sequinel,Vinícius D.N. Bezzon,Armando Beltrán,Sergio Mazurek Tebcherani,José Arana Varela +7 more
TL;DR: The experimental results are in good agreement with first-principles total-energy calculations that were carried out within periodic density functional theory (DFT), and showed that the α-Bi2O3 PL emissions in the low-energy region are attributed to oxygen vacancies that form defect donor states.

Intermetallic formation on the fracture of Sn/Pb solder and Pd/Ag conductor interfaces
TL;DR: In this article, the formation of intermetallic compounds between a thin-film mixed bounded conductor and Sn/Pb solder was investigated with the aid of electron microscopy and X-ray diffraction.

A model for the chemical modification of electrical properties of chalcogenide glasses by bismuth
S.R. Elliott,A. T. Steel +1 more
TL;DR: In this paper, a mechanism is proposed to account for the ability of Bi to change the electrical properties of certain chalcogenide glasses, where the type of bonding at the Bi sites changes from covalent to partially ionic.

Giant Incident Photon-to-Current Conversion with Photoconductivity Gain on Nanostructured Bismuth Oxysulfide Photoelectrodes under Visible-Light Illumination.
Evgeny A. Bondarenko,Evgeny A. Bondarenko,Eugene A. Streltsov,M. V. Malashchonak,Alexander V. Mazanik,Anatoly I. Kulak,Ekaterina V. Skorb,Ekaterina V. Skorb +7 more
TL;DR: Abnormally high photoelectrochemical activity, as well as a band gap energy value favorable for efficient conversion of solar light (1.38 eV, direct optical transitions), proves the potential of bismuth oxysulfidephotoelectrodes for a new generation of high-performance photoconverters.

Chemoselective hydrogenation of 3-nitrostyrene to 3-aminostyrene over Pt-Bi/TiO2 catalysts
Mingli Lan,Bin Zhang,Haiyang Cheng,Xiaoru Li,Qifan Wu,Zhong Ying,Yaxi Zhu,Yan Li,Xiangchun Meng,Fengyu Zhao +9 more
TL;DR: In this paper, a highly selective catalyst of Pt-Bi/TiO 2 was first time developed for the hydrogenation of 3-nitrostyrene (NS) to 3-aminostyrene(AS), with it an excellent selectivity to AS of 96% was achieved at the complete conversion.

Electronegativity values from thermochemical data
TL;DR: In this paper, the electronegativities of sixtynine elements have been calculated from the most recent thermochemical data, and the mean deviation of the calculated electronegativity difference, 0·208 √ †, from the difference of the average electrone-gativities is 0·046 units.

The use of semiconductors in thermoelectric refrigeration
H J Goldsmid,R W Douglas +1 more
TL;DR: In this article, the authors proposed that semiconductors should be chosen with high mean atomic weights and that they should be prepared with thermoelectric powers lying between 200 and 300 μVC-1.

Chemical bonding in bismuth telluride
J.R. Drabble,C.H.L. Goodman +1 more
TL;DR: In this paper, a model for the chemical bondins in bismuth telluride is proposed, which appears to dispose of some of the difficulties involved in earlier models, and is used to explain some properties of BTE and its alloys with BTE.
