TL;DR: In this article, a core/shell nanoparticles with a tailored Ag2S core size and carbon-containing shell thickness were synthesized from aqueous solutions of silver nitrate and sodium sulfide in the presence of a complexing agent and stabilizer.
Abstract: Silver sulfide nanoparticles have been synthesized through chemical deposition from aqueous solutions of silver nitrate and sodium sulfide in the presence of sodium citrate as a complexing agent and stabilizer. The nanoparticles have a Ag2S core with a monoclinic crystal structure, covered with a carbon-containing citrate shell. Varying initial reactant concentrations, we can obtain core/shell nanoparticles with a tailored Ag2S core size and carbon-containing shell thickness.

TL;DR: In this paper, metastable wurtzite CuInS2 nanocrystals and films were successfully synthesized from aqueous solution under atmospheric conditions, and the proposed synthesis strategy may be used as a general process for the synthesis of hydrophilic chalcogenide semiconductor NCs and is scalable for commercial production with minimal environmental impact.
Abstract: For the first time, metastable wurtzite CuInS2 nanocrystals and films were successfully synthesized from aqueous solution under atmospheric conditions. The CuInS2 nanocrystals were prepared by stirring and reflux of a metal salt and sodium sulfide in aqueous solution containing thioglycolic acid as a stabilizer. The good absorption in the visible light region may find interesting application in solar cells. The I–V curve indicated that the wurtzite CuInS2 NCs favored the generation of photoinduced carrier and electronic transmission. The proposed synthesis strategy may be used as a general process for the synthesis of hydrophilic chalcogenide semiconductor NCs and is scalable for commercial production with minimal environmental impact.

TL;DR: In this article, a mathematical model was built based on the response surface methodology (RSM) to understand the swelling mechanism and optimize the swelling condition of bovine hides, and the predicted values were in good agreement with the experimental values by analyzing the absolute as well as relative errors.

TL;DR: In this article, the effects of stirring speed, particle size, and concentration of Na2S on conversion were studied at constant temperature and solid-to-liquid ratio, and it was concluded that leaching of celestite in Na2s solution for conversion to strontium disulfide, SrS2 is possible but slow.
Abstract: Leaching of celestite mineral, SrSO4, with sodium sulfide, Na2S, was investigated from the point of strontium carbonate, SrCO3, production. Experiments were carried out to explain the conversion mechanism of celestite to strontium disulfide, SrS2, in Na2S solution. Effects of stirring speed, particle size, and concentration of Na2S on conversion were studied at constant temperature and solid‐to‐liquid ratio. The results showed that the rate of conversion mainly depends on Na2S concentration. It was concluded that leaching of celestite in Na2S solution for conversion to SrS2 is possible but slow.
