一般描述

元素硫存在于30种不同的固体同素异形体中,其中斜方硫是常温常压下唯一的热力学稳定形式。它可溶于许多有机溶剂,生成大量含氧酸。硫的反应性通常很高;元素硫的S8环很容易被许多亲核反应物破坏。大约在100oC下,羟基离子可与S反应。

应用

它可用于Li-S聚合物电池,也可用作太阳能电池的半导体敏化层CdS/CdSe/ZnS。

Low-dimensional materials usually exhibit mechanical properties from those of their bulk counterparts. Here, we show in two-dimensional (2D) rhenium disulfide (ReS2) that the fracture processes are dominated by a variety of previously unidentified phenomena, which are not present in bulk

How living organisms create carbon-sulfur bonds during the biosynthesis of critical sulfur-containing compounds is still poorly understood. The methylthiotransferases MiaB and RimO catalyze sulfur insertion into tRNAs and ribosomal protein S12, respectively. Both belong to a subgroup of radical-S-adenosylmethionine (radical-SAM)
