Nanotechnology-treated water contains no bacteria and organic dyes and is deemed superior to such methods of treatment. In this paper, an investigation into the light-induced effect on chitosan nanoparticles containing biosynthesized NiO nanoparticles was carried out. The synthesized nanocomposites have utilized characterizations using several methods, like FETEM, FTIR, XRD, XPS, and UV-visible spectroscopy. Under this work, the synthesis and characterization of the NiO@CS nanocomposite, used as an adsorbent to remove organic dyes from water. The organic dyes used were, among others, Congo red (CR) and Malachite green oxalate (MGO). The effect of temperature, pH, dosage, pH, and time on the removal efficiency (%) of adsorbent towards various colours was separately investigated. Kinetics isotherms Langmuir, Freundlich and Temkin as well as thermodynamic parameters (ΔG°, ΔH° and ΔS°) were observed. The linear correlation coefficient, R₂ of the Langmuir adsorption isotherm was almost equal to 1 for all colors which suggests that the adsorption occurred as a monolayer. Adsorption occurred with a reduction in negative enthalpy, free energy, and a drop in entropy at 30°C. The adsorbent was reusable for three cycles without a reduction in removal efficiency (%). Therefore, the NiO@CS nanocomposite may be feasibly applied toward commercial applications from organic colors from aqueous solutions.</div></div>","PeriodicalId":22081,"journal":{"name":"Surfaces and Interfaces","volume":"56 ","pages":"Article 105505"},"PeriodicalIF":5.7,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142742919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Corrosion analysis demonstrated that the deposition of selenium on the surface hindered the movement of ions from the harsh simulated body fluid (SBF) solution.

In this study, vinyltrimethoxysilane (VTMO) modified SiO₂ nanoparticles were synthesized to develop two-component High Solid (2K HS) hybrid clearcoats (CC) which require low-temperature curing. Hansen Solubility Parameters (HSP) and Design of Experiment (DOE) studies provided better optimization in terms of reaction parameters and suitable solvent prediction. Several characterization techniques like FTIR, SEM, and DLS techniques were performed to prove the successful modification of SiO₂ nanoparticles with silane agent, VTMO. HS Hybrid CC formulations were designed for the automotive industry with 1.75 and 3.00 phr (per hundred acrylic polyol resin) VTMO modified SiO₂ nanoparticles. Dynamic Mechanical Analysis (DMA) tests showed that toughness values increase with the nanofiller amount, in contrast to Young's modulus and yield strength due to the various interactions between nanofiller and the polyurethane polymer matrix. The free volume formed between VTMO ligands of the SiO₂ nanoparticles and the polymer matrix provides a low-density region which results in a decrease in time, temperature, and frequency dependent modulus values and glass transition temperature (T_g) of HS Hybrid CC system. Static and dynamic surface tension measurements, water uptake, and cure monitoring result that 1.75 phr nanofiller content in HS Hybrid CC enhances the performance of clearcoats significantly due to the formed low-density region between the nanofiller and the polymer matrix. However, further increase of the nanofiller causes agglomeration and consequently worse clearcoat performance.

One advantage of the approach was that it was easy to use, safe, affordable, and controlled. The CS-NPs of Fe_2.96Cr_0.03Ni_0.01O₄@Ag were successfully synthesized via electrolytic cathodic deposition of FeCrNi alloy thin film on a steel substrate and then annealed at 800 °C for two hours, resulting in a FeCrNiO powder that is converted easily to FeCrNiO@Ag CS-NPs using aqueous Ag-NPs. The XRD patterns of both FeCrNiO and FeCrNiO@Ag CS-NPs show the formation of a mixture of iron oxide (Fe₂O₃) and magnetite oxide (Fe_2.96Cr_0.03Ni_0.01O₄) with an average grain size of 38.36 nm and 30.18 nm, respectively. The synthesized FeCrNiO@Ag CS-NPs exhibit excellent applications in catalytic efficiency during the production of hydrogen from NaBH₄ hydrolysis in addition to the reduction of the nitro group of 4NP to 4AP. In another successful application, the data show that using FeCrNiO@Ag, the dyes' total reduction occurred at 0.42 min for Remazol red (RR), 1.16 min for Methyl orange (MO), 0.83 min for Congo red (CR), and 1 min for Methylene blue (MB). The kinetics investigation was conducted and proved that the reduction reactions of the dyes followed a pseudo-first-order model. This data shows that our catalytic system performs well when compared to the other catalytic systems for dye reduction, and FeCrNiO@Ag CS-NPs is a favorable material for organic dye reduction. Therefore, the CS-NPs exhibit promise efficiency towards important applications in industrial catalysis and dye reduction, as evidenced by their stability and recyclability.</div></div>","PeriodicalId":22081,"journal":{"name":"Surfaces and Interfaces","volume":"56 ","pages":"Article 105486"},"PeriodicalIF":5.7,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142742924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
