Description générale

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.

Application

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

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.

Lanthanide Ions as Photon Managers for Solar Cells

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).
