Here, the most important parameter that affects the photodetective behavior, such as structural, morphological, and optical properties, was analysed by a thorough understanding of nucleation kinetics and particle size distribution correlated with solvent polarity. The charge carrier dynamics of the device have been studied using the SCAPS-1D simulation software for the device configuration FTO/Fe-doped CTS/Al, through electron/hole generation rate, built-in electric field, which also leads to generate energy band diagram for the performance of the photodetector. The particle synthesized in 2PE shows doughnut morphology and EG, PEG shows the spherical morphology with varied particle size, which also accelerated phase formation and defect passivation, improving photoresponse dynamics, exhibiting remarkable specific detectivities of 7.07×10⁹ Jones (2PE), 3.504×10¹⁰ Jones(EG), and 9.58×10¹⁰ Jones (PEG-200) under 1Sun illumination, with fast response and recovery times in high on/off ratios.

Based on the S-V slope and the blank standard deviation, the sensing probe achieved a limit of detection of 0.56 nM (0.75 ng mL^-1).

Variations in the crystallographic parameters are attributed to recrystallization and phase transformation processes driven by the energy stored in the parent Bi₂Te₃ phase.

Therefore, this study systematically investigates the degradation behavior of Mg-Zn-Zr-Nd alloy in HBSS both with and without bovine serum albumin (BSA). The results indicate that BSA effectively inhibits alloy corrosion in the initial stage through adsorption. Although the protective effect diminishes over time due to protein denaturation and complexity effects, the overall corrosion level in BSA-containing solutions remains lower than that observed in the blank environment, reflecting an enhanced corrosion resistance. During tribocorrosion, BSA adsorption reduces wear volume by 50.5% (from 2.734×10⁷ to 1.352×10⁷ μm³) through a synergistic mechanism involving physical/chemical adsorption and lubrication. BSA significantly mitigates the degradation of the alloy's mechanical properties in corrosive environments, thereby contributing to the preservation of its structural integrity. After 7 days of immersion, the loss in ultimate strength decreased from 25.8% in the BSA-free group to 8.9% in the group containing 5 g/L BSA.

By synchronising the voltage sweep with real-time optical emission monitoring, allowing direct observation on the scan rate altering onset and duration of micro discharges can be done. In a Na₂HPO₄ electrolyte system, PEO exhibits quasi-reversible oxidation dominated by hydrated Ti–P–O formation, as revealed by simultaneous mapping of voltametric hysteresis, emission line intensity and XRD analysis. Adding KOH, the process shifts to a field-limited regime characterised by short-lived and high-energy discharges. These conditions promote rapid oxide consolidation, and the formation of compact, amorphous TiO₂ as shown by XRD and EDX. This integrated CV–OES approach reveals the relation of scan rate to discharge duration and energy, and how electrolyte composition governs discharge stability. This integrated diagnostic framework provides mechanistic insights into PEO coating evolution, and offers a pathway to rational control of discharge chemistry, enabling tailored oxide architectures for functional surface applications.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"354 ","pages":"Article 132207"},"PeriodicalIF":4.7,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146191594","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}
