The experimental protocol involved the preparation of the plant extract, followed by its mixing with zinc chloride and deposition onto polished copper substrates by pyrolytic spray at 350°C, then annealed at 400°C. The formation of ZnO NPs was confirmed by various analysis techniques, including X-ray diffraction (XRD), UV–Vis spectrophotometry, and scanning electron microscopy (SEM). The synthesized nanoparticles exhibited a homogeneous morphology, with an average crystalline size of 21.92 nm and a bandgap energy of 2.95 eV, indicating significant ultraviolet absorption. The electrochemical properties of the ZnO NPs/Cu were evaluated for glucose detection in an alkaline medium, showing distinct oxidation and reduction peaks. A decrease in current was observed with increasing glucose concentration, attributed to the saturation of active sites and parasitic reactions. The detection sensitivity was 947.37 µA/cm2 mM before annealing and 2703.43 µA/cm2 mM after annealing, representing a 2.85-fold improvement following thermal treatment. Moreover, their performance as supercapacitors was analyzed, revealing a specific capacitance of 175 F/g before annealing and the peak current was plotted 365 F/g after annealing, thus confirming a marked increase in energy storage capacity after annealing. These results demonstrate the potential of ZnO NPs synthesized via this hybrid green-spray pyrolysis approach for dual applications in glucose sensing and energy storage.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"61 5","pages":"1059 - 1071"},"PeriodicalIF":0.8,"publicationDate":"2026-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145969531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following domestic and international standards for polymer aging, the samples were subjected to the following initial accelerated aging conditions: 168 days at 50°C, 84 days at 60°C, and 42 days at 70°C. The results demonstrate that accelerated aging does not alter the chemical or phase structure of the nonabsorbable sutures. Their strength properties complied with the relevant standard requirements, which supports the suitability of these test conditions for such materials. However, not all initial test conditions suit absorbable sutures because these fibers lose a significant portion of their strength because of pronounced chemical and physical changes.

However, their potential drawbacks are their vulnerability to fluoride-induced corrosion and the release of potentially toxic metal ions, which poses challenges in long-term medical applications. Plasma electrolytic oxidation (PEO) is an effective surface modification process that improves corrosion resistance, wear resistance, and biocompatibility by creating a porous ceramic oxide layer on the metal surface. In this study, Ti6Al4V alloys processed with PEO in a phosphate-based electrolyte containing suspended zirconia (ZrO2) microparticles. The findings substantiated the integration of zirconia into oxide layer as a homogeneously porous structure. Corrosion analysis showed a dramatic enhancement in corrosion resistance of the zirconia-modified Ti6Al4V over Ti6Al4V without zirconia coatings. Microstructural characterization through SEM and EDS showed a uniform distribution of zirconia, which is responsible for improved surface stability. The coating thickness increased up to 27.6 µm with 6 g/L ZrO2, improving protective properties but also leading to excessive porosity at higher concentrations. Wettability and biofilm adhesion tests revealed enhanced antibacterial efficacy, especially against E. coli and S. epidermidis. Roughness tests also validated enhanced osseointegration potential. All these findings support that PEO-based zirconia addition is a promising solution for enhancing the longevity and efficacy of titanium alloys in biomedical fields.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"61 5","pages":"1133 - 1141"},"PeriodicalIF":0.8,"publicationDate":"2026-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145969546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicate that Ti significantly enhances the thermodynamic stability of Cr microalloy steel and increases its corrosion potential. Additionally, as the Ti doping level increases from 0 to 0.087 wt %, the protective capability of the corrosion product layer is progressively improved. The corrosion rate of Ti-doped steel decreases from 2.24 to 1.75 mm/year, representing a 21.9% reduction compared to that of undoped steel. However, when the doping level exceeds 0.087 wt %, the enhancement in corrosion resistance becomes minimal, with little significant change in the corrosion rate. Furthermore, long-term corrosion studies of the product layers revealed a strong synergistic interaction between Ti and Cr, leading to greater enrichment of Cr in the product layers formed on Ti-doped steel. Moreover, Ti promotes the formation of γ-Fe2O3, which facilitates the development of a denser and more stable protective oxide layer.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"61 5","pages":"1151 - 1171"},"PeriodicalIF":0.8,"publicationDate":"2026-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145969456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, optical loss due to moderate optical properties and degradation is the main challenge for FTO-configured perovskite solar cells. This research intends to enhance the optical properties and electrical properties of hybrid perovskite solar cells featuring 10, 20, 30, and 40 nm of tin oxide (SnO2) electron transport layer (ETL), which is formed through the atomic layer deposition technique. Final perovskite solar cells consist of FTO/SnO2/CH3NH3PbI3/poly(triarylamine) (PTAA)/fullerene (PCBM)/copper (Cu) layers. However, the role of SnO2 ETL thickness in influencing the efficiency and stability of PSCs remains an active area of investigation. The findings underscore the potential of tailored ETL architectures to elevate the overall performance and environmental robustness of PSCs. The 40 nm SnO2 layer, optimized for the highest power conversion efficiency (PCE) of 24.0%, achieved the greatest short-circuit current density (Jsc) of 25 mA/cm2, open-circuit voltage (Voc) of 1.18 V, and fill factor (FF) of 78.1%.
