Cobalt in Nitrogen-Doped Graphene as Single-Atom Catalyst for High-Sulfur Content Lithium-Sulfur Batteries.

Journal of the American Chemical Society, 2019
Because of their high theoretical energy density and low cost, lithium-sulfur (Li-S) batteries are promising next-generation energy storage devices. The electrochemical performance of Li-S batteries largely depends on the efficient reversible conversion ...

Sulfur revisited

Journal of the American Academy of Dermatology, 1988
Sulfur is a time-honored therapeutic agent useful in a variety of dermatologic disorders. Its keratolytic action is due to formation of hydrogen sulfide through a reaction that depends upon direct interaction between sulfur particles and keratinocytes.

Sulfur and Sulfuric Acid

2007
Sulfur is one of the few elements that is found in its elemental form in nature. Typical sulfur deposits occur in sedimentary limestone/gypsum formations, in limestone/anhydrite formations associated with salt domes, or in volcanic rock [1]. A yellow solid at room temperature, sulfur becomes progressively lighter in color at lower temperatures and is ...

Bidirectional Catalysts for Liquid–Solid Redox Conversion in Lithium–Sulfur Batteries

Advances in Materials, 2020
Accelerated conversion by catalysis is a promising way to inhibit shuttling of soluble polysulfides in lithium–sulfur (Li–S) batteries, but most of the reported catalysts work only for one direction sulfur reaction (reduction or oxidation), which is ...

Capture and Catalytic Conversion of Polysulfides by In Situ Built TiO2‐MXene Heterostructures for Lithium–Sulfur Batteries

Advanced Energy Materials, 2019
The detrimental shuttle effect in lithium–sulfur batteries mainly results from the mobility of soluble polysulfide intermediates and their sluggish conversion kinetics.

Nickel mediated sulfur–selenium and sulfur–sulfur bond formation

Chemical Communications, 1999
Electrophilic addition of the PhSeCl to a nickel dithiolate yields S,S′-bis(phenylselenenyl-N,N′-bis(mercaptoethyl)-1,5-diazacyclooctane nickel(II) dichloride and a dimeric, intermolecular bis-disulfide which results from ligand oxidation.

Sulfur Metabolism in Phototrophic Sulfur Bacteria

2008
Phototrophic sulfur bacteria are characterized by oxidizing various inorganic sulfur compounds for use as electron donors in carbon dioxide fixation during anoxygenic photosynthetic growth. These bacteria are divided into the purple sulfur bacteria (PSB) and the green sulfur bacteria (GSB). They utilize various combinations of sulfide, elemental sulfur,
