The effects of important parameters such as SiC nanoparticles, direct current, and pulse reverse electrodeposition on the microstructure, wear, and corrosion resistance of Ag-Si-SiC coatings were investigated. The coatings were evaluated using different characterization techniques such as SEM, EDS, XRD, XRF, LSV and electrochemical analysis. In addition, the pin-on-disk method and Vickers microhardness were developed to investigate the wear behavior. The coating process resulted in coatings with a target thickness of 30–40 µm, which were accompanied by a significant improvement in surface quality. This improvement was reflected in the roughness reduction from 251.4 µm to 107.8 µm. The results of the analyses showed that coatings with a Si content of 0.3 % exhibited a reduction in grain size from 20 µm to 1.2 µm and a subsequent reduction in corrosion current strength from 478×10⁻⁸ A.cm⁻² to 7.31×10⁻¹⁰ A.cm⁻² in the artificial human sweat electrolyte. The addition of 4 g/L SiC nanoparticles resulted in increased wear resistance, as indicated by a decrease in the friction coefficient from 0.5 ± 0.05 to 0.4 ± 0.03 while maintaining the same corrosion resistance. The remarkable performance of the coatings was observed under exposure to corrosive ammonium sulfide electrolytes and artificial human sweat, illustrating the effectiveness of pulsed reverse electrodeposition in producing dense, fine-grained structures of Ag-Si-SiC composite coatings, resulting in increased mechanical and corrosion resistance.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"28 ","pages":"Article 100791"},"PeriodicalIF":7.5,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144280395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the effects of illumination and deposition potential on the properties of Ni-Ce oxide black protective coatings and elucidates the possible reasons for the changes in hydrophobicity. The results indicate that illumination accelerates the coating deposition process. Under illumination, the coating thickness increased from 3.27 μm to 5.44 μm, and the surface roughness rose from 0.38 to 0.84. The absorption rate in the UV–visible region and emission properties of the coating deposited with photo illumination reached up to 95 % and 0.87, respectively. Moreover, by manipulating of the deposition potential range, precise control over the coating’s thickness and roughness was achieved, enabling the optimization of its absorption and emission properties. The optimal deposition potential range was found to be between 0 and -1.4 V. Illumination conditions also play a crucial role in the rate of change of the water contact angle. The contact angle of water increased from 19.2° to 132° as the placement time increased. This significant enhancement in the water contact angle variation could be attributed to the adsorption of hydrocarbons from the ambient air. This research provides a promising methodology for the development of black coatings with exceptional absorptivity and emissivity, which may find applications in the aerospace industry and precision optical instruments.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"28 ","pages":"Article 100788"},"PeriodicalIF":7.5,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144263819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study systematically addresses this aspect by investigating how IBPs control ice accretion when grafted onto an aluminum alloy using polyethylene glycol (PEG) linkers of various lengths and on the polymer backbone of a PEG hydrogel matrix. Freezing experiments monitored through thermal imaging reveal that the degrees of freedom of the proteins significantly influence their functionality. Specifically, we demonstrate that when the degrees of freedom of anti-freeze proteins (AFPs) are restricted by their functionalization on surfaces using short linkers or when they are present in restricted volumes in polymers, they behave as ice-nucleating proteins (INPs) promoting ice accretion. In conditions where their degrees of freedom are enhanced (long linkers, water-rich environment), AFPs effectively inhibit ice nucleation and propagation. The work underlines the relevance of protein mobility as a so far unforeseen key design factor needed to fully benefit from the potential use of natural or synthetic AFPs grafted on surfaces for cryopreservation of biological samples and the design of next-generation low-icing surfaces and coatings.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"28 ","pages":"Article 100790"},"PeriodicalIF":7.5,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144254513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The work presented in this study demonstrates the utility of a combined XPS and HAXPES analysis to isolate forensic signatures on the surface and into the bulk of uranium dioxide. A non-destructive depth profile, using the transitions observable with a 9.25 keV excitation source, highlighted an oxidized overlayer deeper than the XPS sampling depth. Peak fitting of high-resolution spectra allows identification of uranium oxidation states as well as inspection of secondary features, which provide insight into the material characteristics with an evolving chemistry from the surface to a more bulk like composition.
