The preparation of alkylidene sulfur tetrafluorides, R 2C SF 4, is presented. They exhibit a rigid structure, which can be described as trigonal bipyramidal or pseudo-octahedral around sulfur. The chemistry is mostly addition across the sulfur carbon double bond, but also carbene formation. In ...
Its density is 1.96 g/cm3, with a melting point of 119.3°C.3. Amorphous sulfur is formed when molten sulfur is quickly cooled. Amorphous sulfur issoft and elastic, and as it cools, it reverts back to the orthorhombic allotropic form.Sulfur, in its elemental form, is rather common and ...

Such a scenario is reasonable as the long known reaction of disulfide bonds with sulfite (RS SR + SO32 − ↔ RS− + RS C SO3−) is fully reversible at pH values above 7.0 [62]. Just as proposed for the situation in sulfate reducers, the intramolecular disulfide in DsrC could ...
18. The metal alkoxide compound having at least one labile sulfur atom reacts with the metal alkoxide compound having at least one reactive moiety which is capable of bonding with the organic resin to form a sol-gel which bonds to the surface of the metal, and which includes reactive moietie...
First, some protein thiols may react with H2O2 to become sulfenylated, and then with H2S to become persulfidated. Second, some protein disulfide bonds may react with H2S to generate a persulfide. However, both reactions are slow11 and unlikely to explain the fact that so many proteins can ...

Li–S batteries with the Bi2S3 catalyst work steadily at a high rate of 5.0C with a high-capacity retention of ~85% after 500 cycles. A high areal capacity of ~21.9 mAh cm−2 was obtained under a high sulfur loading of 17.6 mg cm−2 but a low electrolyte/sulfur ...
