LGeCl (L = PhC(NtBu)2) was treated with elemental sulfur in THF to afford [{PhC(NtBu)2}2Ge2(μ-S)2Cl2] (2) in 44% yield instead of yielding a compound containing a GedS double bond. It was revealed by theX-ray single-crystal structure that there is noGedS unit in 2. Instead, 2 features a four-membered ring containing two germanium and two sulfur atoms. The four-membered Ge2S2 ring is planar and ...

Formate-grown cells of the obligately chemolithoautotrophic acidophile Thiobacillus ferrooxidans were capable of formate- and elemental sulfur-dependent reduction of ferric iron under anaerobic conditions. Under aerobic conditions, both oxygen and ferric iron could be simultaneously used as electron acceptors. To investigate whether anaerobic ferric iron respiration by T. ferrooxidans is an ene...

In natural and laboratory-based environments experiencing sustained counter fluxes of sulfide and oxidants, elemental sulfur (S(0))-a key intermediate in the sulfur cycle-can commonly accumulate. S(0) is frequently invoked as a biomineralization product generated by enzymatic oxidation of hydrogen sulfide and polysulfides. Here we show the formation of S(0) encapsulated in nanometre to micromet...

A total of 75 microorganisms were obtained from high-sulfur content environmental samples using different sulfur sources. Fifty-four of them had the ability to oxidize sulfur at 1% (w/v) in liquid culture, however only three of them AZCT-M125-5, AZCT-M125-6, and AZCT-M125-7 were able to grow autotrophycally using elemental sulfur at concentrations higher than 1 % and up to 9 % (w/v) as energy s...

Sulfur is an attractive cathode material with a high specific capacity of 1675 mA h g , but its rapid capacity decay due to polysulfide dissociation presents a significant technical challenge. Here, we present the fabrication of a TiO2/S composite cathode by encapsulating elemental sulfur into TiO2 nanotube hosts for high performance lithium–sulfur batteries. A high capacity of 913 mA h g 1 has...
