Semiconductor sensitized solar cell interfaces have been studied with photoelectron spectroscopy to understand the interfacial electronic structures. In particular, the experimental energy level alignment has been determined for complete TiO2/metal sulfide/polymer interfaces. For the metal sulfides CdS, Sb2S3 and Bi2S3 deposited from single source metal xanthate precursors, it was shown that bo...

Nanotechniques that can improve the effectiveness of radiotherapy (RT) by integrating it with multimodal imaging are highly desirable. Results In this study, we fabricated Bi2S3 nanorods that have attractive features such as their ability to function as contrast agents for X-ray computed tomography (CT) and photoacoustic (PA) imaging as well as good biocompatibility. Both in vitro and in vivo s...

Photocatalytic reduction of hexavalent Cr(VI) couping oxidative degradation organic contamination is an emerging and practical approach for water treatment. In this study, Z-scheme g-C3N4/Bi2S3 heterojunctions with intimate interface were successfully synthesized by direct growth Bi2S3 on g-C3N4 surface. Notably, the photocatalytic performance was influenced content. The optimized 2% heterojunc...

Submitted for the MAR11 Meeting of The American Physical Society Phase diagram of thermoelectric Bi2S3-Bi2Se3-Bi2Te3 system WEISHU LIU, QINYONG ZHANG, QIAN ZHANG, Boston College, BO YU, GANG CHEN, ZHIFENG REN, Boston College, BOSTON COLLEGE TEAM, MIT TEAM — It is well known that the highest ZT value, at an optimized carrier concentration, is mainly determined by a material parameter β = μ(m*/m0...

High edge energy storage with large life-span stable materials have become the most significant and major requirement in near future. Bismuth sulfide (Bi2S3) nanoparticles (NPs) was effectively synthesized by utilizing bismuth diethyldithiocarbamate (Bi[DTC]3) complex as single-source antecedent. The Bi2S3 NPs were affirmed structural, morphological thermal analysis various analytical studies. ...
