Here, we introduce an <em>in-situ</em> approach combining cyclic voltammetry with optical emission spectroscopy (CV-OES) to directly correlate electrochemical parameters with plasma discharge behaviour during PEO of titanium. 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}

In contrast, the splash zone and waterline zone form thin, defective, and loose films, leading to poor protection. The oxide film's resistivity distribution closely correlates with corrosion resistance: high initial resistivity in the full immersion zone forms an effective barrier, while low, uneven resistivity in the other two zones reflects film defects, consistent with macroscopic electrochemical indicators.

The Pt NPs were synthesized using a green method employing <em>Foeniculum vulgare</em> (<em>F. vulgare</em>) seed extract. These nanoparticles were then loaded with PTX and coated with chitosan (Ch) to enhance drug delivery efficiency. The physicochemical properties of the nanoparticles were characterized using X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM), Thermogravimetric Analysis (TGA), Field Emission Scanning Electron Microscopy (FESEM), Fourier Transform Infrared Spectroscopy (FTIR), Ultraviolet-Visible (UV-Vis) absorption spectroscopy, and zeta potential measurements. X-ray Diffraction (XRD) analysis confirmed the high purity and distinct crystalline nature of the resulting nanoparticles (Pt NPs and Pt-PTX-Ch). FESEM analyses revealed that the nanoparticles had a spherical morphology with a tendency to aggregate, with an average size ranging between 17 and 20 nm. Spectroscopic analysis showed absorption peaks at 270 nm for Pt NPs and 279 nm for Pt-PTX-Ch. Surface measurements recorded zeta potential values of −24 mV for Pt NPs and +36 mV for Pt-PTX-Ch.
