Cu thin films on quartz glass substrates were prepared using a sputtering technique followed by a thermal treatment. The samples were annealed at high temperatures such as 200, 400, and 600 °C for 2 h in a tubular furnace. Surface morphology and elemental composition were investigated using a high-resolution scanning electron microscope (FESEM) and SEM-aided energy dispersion spectroscopy (EDS), respectively. At high temperatures, the thin films were found to have clusters and voids. Detailed studies on optical properties such as ultraviolet–visible (UV–vis) absorptions, energy band gaps and Urbach energies have been carried out. A red shift in absorption edges (from 464 to 616 nm), a decrease in energy band gaps (from 2.38 to 1.54 eV) and an increase in Urbach energies (from 193 to 272 meV) were observed for those samples annealed at higher temperatures. Sessile drop tests were carried out to find the wetting contact angle (WCA) and to demonstrate the hydrophobicity of the thin film of pristine Cu and those treated at high temperatures. An approximate WCA of 71.9° was determined for the Cu thin film. Following treatment at 200 °C and 400 °C, respectively, the samples' surfaces increased in hydrophobicity by 92.4° and 85.2°. Nevertheless, the same thin film's WCA was decreased and its hydrophilicity increased during additional annealing. Cu-based thin films have been suggested as the active layer in an SPR sensor model, and the spectrum and angular resolved reflectance properties have been thoroughly investigated. At spectral wavelengths of 600, 700, and 800 nm, the optimum thickness of Cu thin film was determined to be 40 nm at SPR angles of 44.7°, 42.7°, and 42.15°.</div></div>","PeriodicalId":17219,"journal":{"name":"Journal of Science: Advanced Materials and Devices","volume":"10 1","pages":"Article 100839"},"PeriodicalIF":6.7,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143102319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a ternary heterojunction photocatalyst, Bi₂O₃/(BiO)₂CO₃/g-C₃N₄, demonstrated a multifunctional high photocatalytic performance in the degradation of various dyes, including methyl orange (MO), methylene blue (MB), rhodamine B (RB) and xanthates such as potassium ethyl xanthate (PEX), potassium amyl xanthate (PAX) and sodium isopropyl xanthate (SIPX), under visible light irradiation. The Bi₂O₃/(BiO)₂CO₃/g-C₃N₄ photocatalyst was synthesized by heating a mixture of urea and arc discharge synthesized Bi₂O₃-based nanoparticles at 550 °C. This photocatalyst exhibited higher photocatalytic activity compared to Bi₂O₃/(BiO)₂CO₃ and g-C₃N₄. The photocatalysts were characterized and studied by FTIR, XRD, FESEM-EDS elemental mapping, HR-TEM, UV–visible, BET and PL. The formation of an interface between Bi₂O₃/(BiO)₂CO₃ and g-C₃N₄ significantly improved photocatalytic performance by facilitating the effective separation of photogenerated electron-hole pairs. Stability tests of Bi₂O₃/(BiO)₂CO₃/g-C₃N₄ during the degradation of MO demonstrated the photocatalyst's excellent stability and reusability, indicating its potential for practical applications in mineral processing wastewater treatment. Reactive species trapping experiments revealed that holes (h⁺) played the most significant role in photodegradation, followed by hydroxyl radicals (^•OH), while superoxide radicals (^•O₂⁻) had a lesser impact. Study of two possible photocatalytic mechanisms suggested that the transfer of photogenerated carriers in Bi₂O₃/(BiO)₂CO₃/g-C₃N₄ is more likely to follow a double Z-scheme photocatalytic system. The enhanced photocatalytic performance of Bi₂O₃/(BiO)₂CO₃/g-C₃N₄ can be attributed to considerable specific surface area, stronger visible light absorption and most importantly, well-matched band potentials between Bi₂O₃, (BiO)₂CO₃, and g-C₃N₄.

This study has aimed to provide a comparison between the encapsulated ethinyl estradiol with carboxymethyl-β-CD (CM-β-CD) and β-CD. For this purpose, different steps of the experiments were monitored using FT-IR, XRD, BET, DLS, and Zeta analyses. The morphology of the prepared inclusion complexes was investigated using FE-SEM imaging that shows nano-sized products with non-spherical structures. The thermal stability of EE and its final compounds were assessed through TGA analysis. In addition, encapsulation efficiency (EE%), phase solubility study, <em>in vitro</em> drug release, and their related kinetic studies were conducted by using the UV–visible spectroscopic method. The obtained data reveals that CM-β-CD/EE has roughly 1.5-fold higher water solubility. Besides, the cumulative release for CM-β-CD/EE was found to be 97%, while it was 46% for β-CD/EE. In contrast, the efficacy of the encapsulation process for β-CD was fairly more impressive than CM-β-CD by 97.5 and 90.62, respectively.

The primary reason for the increase in the strength of the Cu strip is the combined strengthening effect of dislocation, grain boundary and texture, as well as the strengthening effect provided by some lattice friction. The grain orientation exhibited periodic transitions between &lt;110&gt; and &lt;111&gt;, &lt;001&gt;, which provides assistance for grain refinement and dislocation accumulation. The grains in the fracture zone of the Cu strip are elongated and refined during stretching, and flow towards the central axis of the cross-section.
