Metal-Sulfur Compounds in N2 Reduction and Nitrogenase-Related Chemistry.

Chemical Reviews, 2020
Transition metal-sulfur (M-S) compounds are an indispensable means for biological systems to convert N2 into NH3 (biological N2 fixation), and these may have emerged by chemical evolution from a prebiotic N2 fixation system.

Crystalline Multi-Metallic Compounds as Host Materials in Cathode for Lithium-Sulfur Batteries.

Small, 2021
Lithium-sulfur (Li-S) battery is one of the most promising next-generation rechargeable batteries. Lots of fundamental research has been done for the problems during cycling like capacity fading and columbic efficiency reducing owing to severe diffusion ...

Origin of polar organic sulfur compounds in immature crude oils revealed by ESI FT-ICR MS

Organic Geochemistry, 2018
Organic sulfur compounds (OSCs) are abundant in immature crude oils, including “polar” OSCs that are defined here as compounds containing one or more heteroatom(s) in addition to sulfur atoms having sufficient polarity to be analyzable by electrospray ...

Polarography of sulfur compounds

1987
Publisher Summary This chapter discusses the polarography of sulfur compounds. Many sulfur compounds, both inorganic and organic, exhibit electrochemical behavior that is useful for analytical purposes. Simple polarography with a dropping mercury electrode can provide a versatile method for the simultaneous identification and quantitative ...

Low Sulfur Compounding

Rubber Chemistry and Technology, 1934
Abstract Since the beginning of the rubber industry, sulfur dosages used for soft rubber have declined from 20 to 2 or 3 per cent customary today. The decline is still under way, and present sulfur ratios are high in comparison with what is actually required to produce satisfactory commercial vulcanization—fractions of 1 per cent. Vulcanization

Sulfur-containing Compounds

1978
The weak sulfur-sulfur bond in elemental sulfur allows carbon-centred radicals and thiyl radicals to effect Sh2 reactions at such sulfur atoms leading to the formation of poly sulfides. For example [1], $$ Me_2 \dot CCN + S_8 \to Me_2 (CN)CS_n C(CN)Me_2 $$ and [2] $$ MeSSMe\xrightarrow{{120^\circ C}}2MeS \cdot $$ $$ MeS \cdot + S_8 ...

Analysis of corrosion scales formed on steel at high temperatures in hydrocarbons containing model naphthenic acids and sulfur compounds

Corrosion, 2014
Corrosive naphthenic acids and sulfur compounds in crude oils present a major challenge for refineries from a corrosion perspective. Although it is accepted that some sulfur compounds may form protective FeS scales on the metal surface and deter ...
