General description

Elemental sulfur exists in thirty different solid allotropes of which orthorhombic sulfur is the only thermodynamically stable form under normal temperature and pressure. It dissolves in a number of organic solvents and forms a large number of oxyacids. Sulfur is generally highly reactive; the S8 ring of elemental sulfur is easily broken by a number of nucleophilic reactants. The hydroxyl ions react with S at about 100oC.


It finds applications in Li-S polymer batteries and as semiconductor-sensitizer layer CdS/CdSe/ZnS for solar cells.

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)...

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).
