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}

While traditional cerium oxide (CeO₂) abrasives suffer from limitations in dispersion stability and the removal of post-polishing residues, a novel mesoporous CeO₂@MOF-5 composite abrasive was developed to enhance Ce³⁺ ion concentration for improved polishing performance. The composite abrasives were structurally characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM), and were found to exhibit hierarchical porosity and uniform morphology. X-ray photoelectron spectroscopy (XPS) analysis revealed an increased concentration of Ce³⁺ ions compared to pure CeO₂, which was attributed to the synergistic interaction between CeO₂ and the MOF-5 framework. CMP tests demonstrated that composites containing 2.00 wt% MOF-5 achieved optimal performance, attaining an MRR of 17.37 μm/h—representing a 39 % enhancement over pure CeO₂ abrasives (10.60 μm/h)—while simultaneously reducing the post-polishing surface roughness (Sa) to 0.31 nm, which was significantly lower than that of conventional CeO₂ (Sa = 1.81 nm). Wettability analysis via contact angle measurements showed enhanced slurry-substrate interactions for CeO₂@MOF-5, and tribological studies revealed a higher dynamic friction coefficient that promoted increased interfacial shear stress.

In this work, the passivation effects of potassium cation-18-crownether-6 (18C6–K⁺) molecules on the surface defects of FAPbI₃(001) were investigated by using first-principles calculations. The adsorption energy of 18C6–K⁺ small molecule on the defective surface were calculated to be negative, indicating stable adsorption on the FAPbI₃(001) surface. Calculations of defect energy levels showed that V_I and I_i defects are shallow-level defects, while I_Pb, Pb_I, and Pb_i defects are deep-level defects. And V_Pb acts as a deep-level defect on the PbI₂-terminated surface, while as a shallow-level defect on the FAI-terminated surface. After 18C6–K⁺ passivation, the defect formation energies of vacancy (V_I), interstitial (Pb_i), and antisite (Pb_I) increased, suggesting inhibition of defects formation on the FAPbI₃(001) surface. Work function analysis reveals that the introduction of 18C6–K⁺ molecules facilitates electron transitions by reducing the work function and enhancing the alignment of energy levels. The TDOS analysis, combined with CDD calculations, indicates that the passivation mechanism by 18C6–K+ is predominantly due to interactions between iodine (I) and ether (C–<em>O</em>–C), rather than between lead (Pb) and ether.
