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

The newly prepared complex [Pd(IPr*(OMe))(cin)(Cl)] provides high catalytic activity for carbon-sulfur cross-coupling reactions. Nonactivated and deactivated aryl halides were successfully coupled with a large variety of aryl- and alkylthiols using this well-defined palladium N-heterocyclic carbene (NHC) complex.

Spectral conversion for solar cells is an emerging concept in the field of photovoltaics, and it has the potential to increase significantly the efficiency of solar cells. Lanthanide ions are ideal candidates for spectral conversion, due to their high luminescence efficiencies and rich energy level structure that allows for great flexibility in the upconversion and downconversion of photons in a wide spectral region (NIR-VIS-UV).
