The SnS thin films were deposited at room temperature using a modified version of the successive ionic layer adsorption and reaction (SILAR) method. The deposited samples were confirmed to be SnS through XRD, XPS, and EDAX analysis. The XRD analysis revealed that the SnS thin films are polycrystalline with an orthorhombic crystal structure. Variations in the number of SILAR cycles resulted in changes in film thickness, crystallinity, crystallite size, and morphology. The SnS thin films were utilized to remove heavy metals from wastewater. UV–visible spectroscopic examination and ICP-OES analysis demonstrated that SnS thin films effectively removed chromium (Cr(VI)) from contaminated water. Under irradiation from a xenon lamp, the SnS thin films eliminated nearly 99 % of Cr(VI) from a 100 ml solution (initial concentration - 25 mg/l, pH - 2.5) within 80 min. Additionally, the SnS thin films removed 97 % of Cr(VI) under ambient light conditions and 94 % in dark conditions. The removal of Cr(VI) by the SnS thin films was identified as an adsorption-reduction process, with XPS analysis of the spent sample confirming the formation of Cr(III). The SnS thin films exhibited high efficiency, easy recovery, and reusability for Cr(VI) removal. The study also investigated the impact of several factors on chromium removal efficiency, including initial pollutant concentration, solution pH and salinity, and speed of magnetic stirring. Furthermore, the selectivity of SnS thin films was demonstrated through their efficiency in removing cadmium and lead. The thin films removed 72 % of cadmium in dark conditions and 82 % under illumination within 40 min. The lead removal rates were 78 % in dark conditions and 99.8 % in illuminated conditions within 40 min.

Among various methods, cold spray deposition shows great potential in preparing high-performance silicon-based electrodes. However, traditional cold spray technology faces challenges in directly depositing nanopowders. One viable solution is to prepare nanopowders into nanosuspensions, atomize them into micron-sized droplets, and inject them into the nozzle, utilizing the droplets as carriers to achieve silicon nanopowder deposition. Based on this approach, this paper employs numerical simulation to study the effects of gas parameters (pressure, temperature), nozzle structural parameters (throat diameter, exit diameter, expansion ratio, divergent length, injection position and angle), and droplet composition (water content) on bow shock and impact velocity. The results show that the pressure of the driving gas and the geometric parameters of the nozzle will affect the bow shock near the substrate, and further affect the impact velocity of the droplets. Since the droplets is radially injected, there is a “hindering” effect between the powder feeding gas and the driving gas. The pressure of the driving gas not only affects the bow shock, but also affects the trajectory of the droplet movement. While the geometric parameters of the nozzle need to be comprehensively considered to weaken bow shock waves and increase impact velocity. Gas temperature has significant effects on atomized droplets deposition and the solidification and evaporation of droplets will affect droplet acceleration behavior. Droplet composition influences impact velocity primarily through composite density and evaporation behavior of droplets and appropriate droplet component ratios can effectively improve droplet impact velocity.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"341 ","pages":"Article 130919"},"PeriodicalIF":4.3,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
