The inhibitors, prepared using dimethylamine, isopropyl chloride, and imidazole, were analyzed through thermometric, gravimetric, and electrochemical methods. Results showed that the inhibitors effectively reduced corrosion rates and a maximum inhibition efficiency of 88.9 % was achieved at an optimum inhibitor concentration of 0.7 g/L. Thermometric analysis revealed a significant reduction in reaction numbers, while gravimetric measurements indicated a weight loss reduction of up to 85 % compared to the uninhibited system. Electrochemical studies demonstrated enhanced corrosion resistance, with a substantial increase in charge transfer resistance (Rct) from 41.2 Ω cm² (blank) to 257.5 Ω cm² (0.7 g/L inhibitor). Adsorption isotherm analysis indicated adherence to Langmuir behaviour, with an adsorption equilibrium constant (k) of 0.904 and a coefficient of determination (R²) of 0.9953, thus suggesting monolayer adsorption. Scanning Electron Microscopy (SEM) revealed smoother surface morphology in the presence of the inhibitors, while Density Functional Theory (DFT) calculations showed favourable adsorption energy (-44.13 kJ/mol) and a low energy gap (ΔE = 4.63 eV), highlighting the inhibitors’ reactivity. These findings confirm the effectiveness of ionic liquids as eco-friendly inhibitors for mild steel corrosion in alkaline environments and underscore their potential for industrial applications requiring sustainable corrosion protection strategies.</div></div>","PeriodicalId":21085,"journal":{"name":"Results in Surfaces and Interfaces","volume":"20 ","pages":"Article 100581"},"PeriodicalIF":0.0,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144297878","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}

With recent advances in material technology, the applications of titanium dioxide (TiO₂) and zinc oxide (ZnO) as UV filters in sunscreens have been widely adopted, therefore, they are selected as the main focal point of this review. Insights into the mechanisms of different types of sun protection exhibited by both conventional microparticles and novel nanoparticles are also provided. In addition, various methods used to evaluate the protection performance of sun protection are also discussed in detail. The review further critically evaluates the safety issues associated with TiO₂ and ZnO nanoparticles, as well as the potential risks, and proposes strategies to improve their safety when they are used in sunscreen.</div></div>","PeriodicalId":21085,"journal":{"name":"Results in Surfaces and Interfaces","volume":"20 ","pages":"Article 100580"},"PeriodicalIF":0.0,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144513496","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}

Its ability to resolve isotopes is especially attractive in studying transmutation products of single crystal tungsten (SCW) post neutron irradiation. Tungsten (W) is a contender of plasma facing materials (PFMs) due to its high thermal and radiological stability. PFMs to be used in the construction of fusion vessels are subject to high temperature and neutron irradiation, resulting in changes to materials including transmutation, which ultimately impact material mechanical and thermal properties. We used IONTOF TOF.SIMS V instrument equipped with a 30 keV Bi₃⁺ primary ion beam to study pristine SCW and irradiated SCW speciemens. Scanning electron microscope coupled with focused ion beam (SEM-FIB) was used to reduce the dosage of neutron irradiated tungsten and prepare for specimens for SIMS analysis. Static ToF-SIMS spectra were obtained, and transmutation product peak identification was presented in this work. Identified molecules and molecular fragments were compared against isotope theoretical mass to charge ratios of tungsten, rhenium, osmium, and other relevant products. Our results show that ToF-SIMS provides a viable means to study transmutation products of W post neutron irradiation. Such applications are suitable to investigate transmutation effects on materials that are being considered and developed for fusion pilot plants.</div></div>","PeriodicalId":21085,"journal":{"name":"Results in Surfaces and Interfaces","volume":"20 ","pages":"Article 100577"},"PeriodicalIF":0.0,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144240311","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}

Due to their technical and compositional complexity, a multi-analytical approach was adopted, combining non-invasive and micro-destructive investigations. Non-invasive investigations, including Digital Optical Microscope (DOM), UV-Induced Visible Fluorescence (UVF), and infrared reflectography (IRR), provided valuable information on the decorative surface and preliminary data on deterioration. In addition, portable X-ray fluorescence (p-XRF) and Fibre-Optic Reflectance Spectroscopy (FORS) analyses were used to identify chromophores in the painted, silvered, and gold-plated layers. Further insights into the execution technique were gained through micro-destructive investigations on sampled materials, employing optical microscopy (OM) on polished and stratigraphic sections, along with Scanning Electron Microscopy (SEM) coupled with Energy Dispersive X-ray spectrometry (EDX). Finally, biological studies were carried out to characterize the leather support, integrated with entomological and microbiological analyses to identify any degradation phenomena due to biological activity. The results indicate that the three altar frontals faithfully reflect the typical characteristics of this artwork type. They also exhibit common degradation forms, such as the darkening of silver leaf, indicating their age and conditions over time.

The diffusion-controlled oxidation forms various oxygen functional groups on the basal planes and the sheet edges, resulting in notable increases in the interlayer distances between the aromatic sheets and remarkable reductions in their number per stack due to chemical exfoliation.
