TL;DR: In this paper, the solubility of sulfur in gaseous hydrogen sulfide has been studied in the H2S-S system at temperatures between 50 and 290°C and pressures up to 200 bars.
TL;DR: The first total synthesis of (+)-luteoalbusins A and B was described in this article, where highly regio-and diastereoselective chemical transformations in their syntheses include a Friedel-Crafts C3-indole addition to a cyclotryptophan-derived diketopiperazine, a late-stage diketo-albusin dihydroxylation, and a C11-sulfidation sequence.
TL;DR: In this paper, a mesoporous hollow sulfurized aminophenol-formaldehyde resin (polysulfane)/carbon nanotube (SAC) spheres with covalently linked short-chain sulfurs were synthesized using a self-template polymerization reaction followed by dissolution and vulcanization processes.
TL;DR: In this paper, a new strategy to stabilize sulfur cathodes with alkylene radicals to covalently connect sulfur through the formation of low-solubility lithium polysulfides, which enables high Coulombic efficiencies of 99.9% at 0.2
