The role of polysulfide dianions and radical anions in the chemical, physical and biological sciences, including sulfur-based batteries
Ralf Steudel,Tristram Chivers +1 more
TL;DR: This review will critically evaluate the techniques used to characterize polysulfide dianions and radical anions both in solution and in the solid state, i.e. Raman, UV-visible, EPR, NMR and X-ray absorption spectroscopy,X-ray crystallography, mass spectrometry, chromatography and high-level quantum-chemical calculations.

TL;DR: It is demonstrated that sulfur radical species, such as the trisulfur ion S3−, form very stable and soluble complexes with Au+ in aqueous solution at elevated temperatures and pressures, which enable extraction, transport, and focused precipitation of gold by sulfur-rich fluids 10–100 times more efficiently than sulfide and chloride only.

The involvement of the trisulfur radical anion in electron-catalyzed sulfur insertion reactions: facile synthesis of benzothiazine derivatives under transition metal-free conditions
TL;DR: In this paper, an efficient and practical synthesis of benzothiazine by K2S initiated sulfur insertion reaction with enaminones via electron catalysis is developed, which provides a new, environment-friendly and simple strategy to construct benzothia derivatives via formation of two C-S bonds under transition metal-free, additive-free and oxidant-free conditions.

Co-variability of S6+, S4+, and S2− in apatite as a function of oxidation state: Implications for a new oxybarometer
TL;DR: In this paper, the authors used micro-X-ray absorption near-edge structures (μ-XANES) spectroscopy at the S K -edge to investigate the oxidation state of S in natural magmatic-hydrothermal apatite and experimental apatites crystallized from volatile-saturated lamproitic melts at 1000 °C and 300 MPa over a broad range of oxygen fugacities.

SUPCRT92: a software package for calculating the standard molal thermodynamic properties of minerals, gases, aqueous species, and reactions from 1 to 5000 bar and 0 to 1000 ° C
TL;DR: The SUPCRT92 software package as discussed by the authors is a suite of three interactive FORTRAN 77 programs, including SPRONS92.DAT, which allows the calculation of the standard Gibbs free energy, enthalpy, entropy, heat capacity, and volume of each reaction specified on the RXN file through a range of conditions specified on CON file.

Atmospheric Influence of Earth's Earliest Sulfur Cycle
TL;DR: Mass-independent isotopic signatures in Precambrian rocks indicate that a change occurred in the sulfur cycle between 2090 and 2450 million years ago, implying that atmospheric oxygen partial pressures were low and that the roles of oxidative weathering and of microbial oxidation and reduction of sulfur were minimal.
