Summary: In this study, the influence of citric acid (CA) concentration on the properties of CuO-Fe2O3-MgO-CuFe2O4 nanocomposites (NCs) was investigated. The NCs were synthesized via auto-combustion method and characterized using various techniques. The results showed that the crystal structure and energy gap of the NCs were affected by the CA concentration. The NCs exhibited adequate antibacterial activity against both Gram-negative and Gram-positive bacteria, with higher activity against Gram-positive bacteria and increased activity with higher CA concentration.

Summary: This work successfully describes the S-scheme-based hydrothermal synthesis of SiO2@CuFe2O4-AgI composites. The nanocomposites with different weight percentages of AgI were tested for their photocatalytic activity in the visible range using methylene blue (MB) and methyl orange (MO) as target pollutants. SiO2@CuFe2O4-AgI with a 15% AgI loading showed superior photocatalytic performance, degrading both MB and MO significantly faster compared to pure and hybrid composites. The increased surface area, efficient separation of photogenerated carriers, and high redox capacity of SiO2@CuFe2O4-AgI (15%) contributed to its enhanced photocatalytic activity. The hybrid composite also exhibited excellent stability and reusability after 10 cycles. This research proposes a novel and cost-efficient approach for creating stable semiconductor-based photocatalytic systems and paves the way for future applications.

Summary: Hybrid ferrite composites were synthesized and characterized using various techniques. The photocatalytic activity of the composites was tested against toxic dyes under visible light illumination. The addition of H2O2 increased the production rate of.OH radicals and enhanced the degradation rate of the dyes. The composites demonstrated high photoactivity and followed pseudo-first order kinetics in the photocatalytic reactions. PL and EIS analysis confirmed enhanced charge separation and migration in the composites. The composites also showed strong chemical stability and efficient generation of reactive species in the photodegradation process.

Summary: Cu/Cu2O/CuO nanocomposites were synthesized for the production of dihydrogen as a fuel source and detoxification of dyes. The nanocomposites exhibited a uniform distribution of Cu and O elements, and the average particle size was approximately 17 nm. The nanocomposites showed a significant boost in performance due to the formation of a heterojunction and the presence of oxygen vacancies. The nanocomposites demonstrated proficiency in photocatalytic hydrogen production and degradation of dyes.

Summary: Photocatalytic degradation of dyes using metal oxides and their composites is an effective method for removing pollutants from wastewater systems. The coupling of metal oxides increases the efficiency of the process, thanks to their ability to absorb broad spectrum light, operate quickly, and exhibit natural p-n characteristics. In this study, binary and ternary nanocomposites of Copper Oxide/Zinc Oxide (CuO/ZnO) and beta cyclodextrin (beta-CD) were prepared using the sol-gel method. The synthesized materials were characterized using various techniques, and their photocatalytic performance was tested using model textile dyes. The addition of beta-CD improved the efficiency of the catalyst and reduced electron hole recombination. The beta-CD-CuO/ZnO nanocomposite exhibited superior photocatalytic activity compared to CuO/ZnO, with degradation efficiencies of up to 89.15% and 79.90% for MB and MG dyes, respectively, after 180 minutes of irradiation.

Summary: This study investigates the magnetic behavior of dextran-coated magnetite nanoparticles (DM NPs) with different sizes. The decrease in saturation magnetization (M-s) with decreasing particle size is modeled by considering a magnetically dead layer on the particle surface. The study also takes into account the contribution of dipolar interactions due to the formation of chain-like clusters of MNPs in the estimation of effective magnetic anisotropy (K-eff) values.
