Hydrogen Sulfide Oxidation by Sulfide Quinone Oxidoreductase

ChemBioChem, 2020
AbstractHydrogen sulfide (H2S) is an environmental toxin and a heritage of ancient microbial metabolism that has stimulated new interest following its discovery as a neuromodulator. While many physiological responses have been attributed to low H2S levels, higher levels inhibit complex IV in the electron transport chain.

Cadmium sulfide with iridium sulfide and platinum sulfide deposits as a photocatalyst for the decomposition of aqueous sulfide

Journal of Photochemistry and Photobiology A: Chemistry, 1995
Abstract The in situ deposition of Pt and Ir on CdS during the photocatalytic decomposition of aqueous sulfide results in the formation of an effective bifunctional photocatalyst (MS/CdS/M, where MS is Pt or Ir sulfide and M is Pt or Ir) which is more active than CdS and metallized CdS.

Adaptations to sulfide in the meiofauna of the sulfide system. I. 35S-sulfide accumulation and the presence of a sulfide detoxification system

Journal of Experimental Marine Biology and Ecology, 1979
Abstract Life in the sulfide system requires the ability to withstand the toxic effects of long-term sulfide stress. The adaptations of sulfide-system interstitial metazoans to sulfide stress have been investigated using 35 S-sulfide. One possible adaptation, the total exclusion of sulfide at the body wall, could not be demonstrated.

Fabrication of Ni Sulfides by Thermal Sulfidation

Materials Science Forum, 2006
The microstructure of Ni sulfides prepared by thermal sulfidation of pure Ni and their dependence of fabrication parameters were investigated by means of scanning electron microscopy and X-ray diffractions. Sulfidation was made by isothermally annealing Ni with the sulfur in vacuum sealed glass ampoules at 673 K for 120 – 600s under the sulfur pressure

Photooxidation of methyl sulfide, ethyl sulfide, and methanethiol

Environmental Science & Technology, 1984
Products of sunlight-irradiated mixtures of oxides of nitrogen and alkyl sulfides (RSR, R = CH/sub 3/, C/sub 2/H/sub 5/) and methanethiol (CH/sub 3/SH) in air include formaldehyde (R = CH/sub 3/), acetaldehyde and PAN (R = C/sub 2/H/sub 5/), sulfur dioxide, and alkyl nitrates (RONO/sub 2/) as well as particulate alkanesulfonic acids (RSO/sub 2/OH) and ...

A Sulfide Oxidase Biosensor for Monitoring Sulfide

CORROSION 2008, 2008
Abstract A sulfide oxidase enzyme electrode is proposed for monitoring of biogenic sulfide resulting from the activities of sulfate-reducing bacteria (SRB). The enzyme which is immobilized in a carbon (graphite) paste with 1,1’ dimethylferrocene, catalyses the oxidation of sulfide to sulfur.

Chemisorption of hydrogen sulfide on lead sulfide

Russian Journal of Electrochemistry, 2006
The hydrogen sulfide chemisorption on lead sulfide at 22–100°C is studied by static testing in a vacuum and by pulsed chromatography. It is established that H2S is sorbed in reversible and irreversible forms and that the process is accompanied by the sample charging.

Sulfides, Arsenides and Complex Sulfides (Sulfosalts)

2020
This mineral class comprises most of the ore minerals. Many of them are opaque, i.e., they are non-transparent, even in thin sections that are not more than 20–30 µm in thickness, and show metallic lustre with different shades of colour.

Sulfides in organic synthesis. Application of sulfides

Russian Chemical Reviews, 1994
The results of studies on the use of sulfides as synthons in organic synthesis are treated systematically and surveyed. The practical applications of sulfides are examined. The bibliography includes 187 references.
