Summary: High quality silver (Ag) decorated CeO2 nanoparticles were prepared by a facile one-step chemical method and used as a catalyst for degrading harmful textile pollutant Rose Bengal dye under sunlight with a high efficiency of 96% degradation rate after 3 hours. The enhancement in degradation efficiency was mainly attributed to the decrease in band gap and charge carrier recombination rate, with a possible degradation mechanism proposed based on the generation of oxygen vacancies due to the decoration of Ag on the CeO2 surface.

Summary: The development of the textile industry has raised concerns due to the contamination of drinking water by organic dyes, which pose a carcinogenic risk to humans. Nanomaterials, particularly semiconductors, have been utilized for photocatalytic degradation of dye pollutants. Various parameters, such as catalyst dosage, irradiation time, light sources, initial dye concentration, temperature, and pH, play significant roles in the degradation process. Different generations of photocatalytic nanomaterials, including single metal nanoparticles, binary and ternary metal oxides, as well as inert solid substrates with photocatalysts, have been employed for dye degradation.

Summary: Planar cobalt(ii) Schiff-base complexes exhibit modified structural and functional properties when encapsulated in zeolite-Y. Encapsulation alters the electron density around the metal center and enhances reactivity for reactions like dye degradation and CO2 transformation. Comparative studies of structural and catalytic modifications provide a rational explanation for the improved reactivity of zeolite encapsulated metal complexes.

Summary: Recently, the use of metal oxide nanoparticles in natural food preservation systems has gained attention, but concerns about their toxicity remained. In this study, a biopolymeric nanohydrogel embedded with metal oxide nanoparticles was synthesized to extend the shelf-life of grapes and reduce dye concentration. Different methods were used to tailor copper, zinc, and iron metal oxide nanoparticles, with iron oxide nanoparticles having the smallest particle size. All metal oxide nanoparticles showed good cell viability. The formulated nanohydrogels with embedded nanoparticles exhibited varying cell viability and spreadability properties, with zinc oxide nanoparticles showing better spreadability. Coating grapes with the formulated hydrogel did not affect their physicochemical attributes during storage, making it a promising natural preservation system.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
