Sulfide, Arsenide und komplexe Sulfide (Sulfosalze) [PDF]

, 1983
Diese Mineralklasse stellt den grosten Teil der Erzminerale. Die sich opak verhaltenden Minerale unter ihnen besitzen einen in der Farbe unterschiedenen Metallglanz. Die nichtopaken unter ihnen sind in dunnen Splittern durchscheinend, besitzen eine sehr hohe Lichtbrechung und zeigen Diamantglanz. Alle geben auf rauher Porzellanplatte einen diagnostisch

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

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.

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.

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.

The Aryl Sulfide Synthesis via Sulfide Transfer

Chemistry – A European Journal, 2022
AbstractAryl sulfides are in great demands in drugs and materials sciences. To avoid using nucleophilic and noxious thiols, many efforts have been focused on exploring novel sulfide resources. Herein, a reductive Pd‐catalyzed, Ni‐mediated method to synthesize aryl sulfides via a sulfide transfer reaction is developed.

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.
