Solubility of platinum in aqueous solutions at 25°C and pHs 4 to 10 under oxidizing conditions
, 2001 Platinum has been found to be mobile under supergene conditions, including placers and weathering profiles. To elucidate the nature of Pt mobility in supergene environments, the dissolution of platinum metal was investigated under physicochemical ...

Nanoscale characterization of thin immersion silver coatings on copper substrates [PDF]
arXiv, 2015 Microelectronic-grade copper foils were immersion silver plated in a home-made non-cyanide alkaline silver nitrate - thiosulfate solution and in two commercially available industrial baths via contact reductive precipitation. The concentration depth profiles of the freshly deposited silver layers were afterwards analyzed at nanoscale resolution by ...

Thiosulfate Disproportionation by Desulfotomaculum thermobenzoicum [PDF]
Applied and Environmental Microbiology, 2000 ABSTRACT Desulfotomaculum thermobenzoicum , but not Desulfotomaculum nigrificans , Desulfotomaculum ruminis , or Desulfosporosinus orientis , grew by disproportionation of thiosulfate, forming stoichiometric amounts of sulfate and sulfide; sulfite

Study on the preparation of nanosulfur/bentonite complex [PDF]
arXiv, 2018 Inorganic compounds with sulfur have a good antifungal efficacy. However there is a limit, sulfur is required in bulk quantities for application. Nanosulfur might have a high anti-bacterial effect in a thin concentration. Nanosulfur-bentonite composite was prepared from nanosulfur made by the reaction between sodium thiosulfate and sulfuric acid and ...

Optimization of Transformable Multiple Impeller (AM Impeller) for Highly Viscous Fluids
Journal of Advanced Manufacturing and Processing, EarlyView.ABSTRACT Mixing performance in a laminar flow with a mixing Reynolds number less than 10 is greatly affected by the geometry of the impeller blades, and how to generate axial flow is important. The authors developed a new AM impeller with a low production cost by combining simple pitched paddle impellers in multiple stages.

Incidence du chlorure de sodium sur la dénitrification d'éluats de résines par une bactérie chimiautotrophe soufre-oxydante [PDF]
, 1996 L'épuration ou la destination finale des éluats de régénération des résines utilisées en dénitratation reste un problème mal résolu. De nouvelles voies sont recherchées; la dénitrification biologique semble très attrayante car elle peut être mise en ...

Thiosulfate Dehydrogenase (TsdA) from Allochromatium vinosum [PDF]
Journal of Biological Chemistry, 2015 Although the oxidative condensation of two thiosulfate anions to tetrathionate constitutes a well documented and significant part of the natural sulfur cycle, little is known about the enzymes catalyzing this reaction. In the purple sulfur bacterium Allochromatium vinosum, the reaction is catalyzed by the periplasmic diheme c-type cytochrome ...
