Bioleaching and electrobioleaching of sulfide minerals
Chalcopyrite, sphalerite, and pyrite, were leached using a bioleaching mode and an electrobioleaching mode. The former mode was used to teach the minerals with the bacterium A. ferrooxidans in a bioreactor. In the latter mode, the leaching of the minerals was performed in a combination of a …

Iron Production by Molten Sulfide Electrolysis
… production of molten iron using a novel sulfide route, molten sulfide electrolysis (MSE) is investigated. Experimental evidence for electrolysis and the key attributes and underlying thermodynamics of MSE for iron production are investigated and discussed, along with sulfidation; the …

Does Sulfide Affect Short Term Iron Oxidation?
<p>The reduction potential of the Fe(II)/Fe(III) redox couple overlaps those of naturally occurring forms of C, O, N and S, and electron transfer between Fe and these elements is often kinetically facile. The chief intermediary in this process appears to be reactive oxygen species (ROS) generated …

Hydrogen Sulfide (H2S) and the Cardiovascular System
Hydrogen sulfide (H2S) has relatively recently been added to a list of endogenously produced gaseous signalling molecules. Our understanding of the science of H2S has advanced rapidly in recent years as exemplified by the fact that, within a mere 10 years, a range of H2S releasing drugs have …

Optoelectronic applications of solution-processable sulfide semiconductors
… sensors is studied with a focus on antimony sulfide (Sb$_2$S$_3$) and antimony sulfoiodide (SbSI). The improvement of the photovoltaic performance in Sb$_2$S$_3$ sensitized solar cells upon the controlled partial oxidation of the absorber layer is investigated. A reduction in charge carrier …

Processing and characterization of zinc sulfide based materials
… spherical, and porous clusters of zinc sulfide (ZnS) nanocrystallites were used as a host material, into which gallium phosphide (GaP) was impregnated. A solution containing a phosphinogallane, (t-Bu)[subscript]2GaP(t-Bu)[subscript]2, and a vapor mixture of GaI and P[subscript]4 were …

On the Cellular Basis of Hydrogen Sulfide Toxicity
Hydrogen sulfide (H2S) produced by colonic sulfate-reducing bacteria represents an insult to the intestinal epithelium potentially contributing to chronic disorders that are dependent on gene-environment interactions. Clinical and epidemiologic studies reveal either persistent sulfate-reducing …
