“…Using a similar approach, Urakaev et al synthesized sulfur nanoparticles via the reaction of sodium thiosulfate pentahydrate with crystalline succinic acid (C 4 H 6 O 4 ) . In their work, the concept of the diluent agent (side final product, Na 2 SO 3 ) was used.…”

In the present study, a quick and environmentally friendly approach has been developed for the synthesis of CuS nanocrystals of different shape with antibacterial activity. The process is completed in 5 min. The presence of copper sulfide in the final products was confirmed by XRD, Raman spectroscopy, XPS, and TEM. The morphology of the product is dependent on whether or not the reaction providing sulfur was realized. When sulfur was included, the CuS particles developed an elongated shape with a thickness in the range between 6 and 8 nm and lengths up to 60 nm. It was found that sulfur plays a role of a nucleation agent in this case and then is removed during the washing process. On the other hand, if just precursors for copper sulfide were used, the morphology was spherical and the crystallite size was around 20 nm. Finally, the antibacterial activity of the products was evaluated. The activity was less selective in the case of CuS prepared by the assistance of sulfur.

“…The SNPs produced by mechanical ball milling have an average size bellow 100 nm (Urakaev et al, 2016). Evaluation of the thermal properties of as-prepared SNPs using TGA revealed that the SNPs synthesised using mechanical ball milling have higher temperatures for complete evaporation and transformation of α-SNP to β-SNP in comparison to macro-elemental sulfur (Urakaev et al, 2016). However, the temperature required to start evaporation and the polymerisation temperature were lower for SNPs produced by ball milling (Urakaev et al, 2016).…”

“…The ball milling method for the production of SNPs is performed through mechanical activation (MA) with a cage rotation rate regulated in the range of 100-600 rpm and an apparatus made of hardened stainless steel with a number of steel balls (Urakaev et al, 2016). The dispersion medium used in this mechano-chemical synthesis consists of sodium thiosulfate pentahydrate/succinic acid system with S 0 as final product of the reaction:…”
