The angle-resolved photoelectron spectroscopy of isolated silver sulfide nanoparticles was carried out by using velocity map imaging technique at the DESIRS beamline SOLEIL synchrotron facility. reported results were obtained after interaction radiation with a polydisperse aerosol produced from aqueous dispersion particles, approximately 16 nm in diameter. and UV–Vis-NIR absorption spectra used...

In this work, electrodes based on carbon aerogels (CA) modified by Ag2S nanoparticles (NPs) were synthesized sputtering and solid-vapor reactions. Nanoparticles identified as silver sulfide (acanthite phase) their size was controlled the time (5s deposition- 8.65 nm ± 1.74 nm, 7s 12.78 8.53 45 s 21.35 10.07 nm). It found that properties vary according to NPs sizes. All exhibited an improved RED...

Numerous mcasuremcnts have been made of the pH, Eh, and the potential of a silver-silver sulfide electrode in sodium sulficlo and sodium polysulf?de solutions. By suitably ostimating the second dissociation constant of hydrogen sulfide and various activity coefficients, it has been possiblo to derive a consistent model for the distribution of the polysulfide and sulfide species, Sp2, S,-“, S,-2...

A multimode, dual functional nanomaterial, CNTs-Ag2S, comprised of carbon nanotubes (CNTs) and silver sulfide (Ag2S) nanoparticles, was prepared through the facile hydrothermal process. Before deposition Ag2S hydrophobic CNTs were modified to become hydrophilic refluxing with a mixture concentrated nitric sulfuric acids. The oxidized employed deposit nanoparticles for their efficient immobiliza...

BACKGROUND The use of a boiling mixture of hydriodic acid, hypophosphorous acid, and hydrochloric acid to reduce any variety of sulfur compounds has been in use in various applications since the first appearance of this method in the literature in the 1920's. In the realm of sulfur geochemistry, this method remains a useful, but under-utilized technique. Presented here is a detailed description...
