Summary: We demonstrate an ideal ZnO@ZnO2 electrocatalyst for efficient oxygen reduction to hydrogen peroxide in a neutral medium. The in situ growth of ZnO2 on ZnO forms heterogeneous interfaces, weakening the binding energies of OOH* and O*. In a 0.1 M K2SO4 electrolyte, ZnO@ZnO2 exhibits nearly 100.0% selectivity for H2O2 production and a production rate of 5.47 mol g(cat)(-1) h(-1) at 0.1 V vs. RHE, with a Faraday efficiency of approximately 95.5%.

Summary: A solid lipid coated calcium peroxide (CaO2) nanocarrier was synthesized to deliver doxorubicin and iron-oleate complex for O-2 /H2O2 -sufficient chemo/chemodynamic cancer therapy. The biocompatible Fenton catalyst, iron-oleate, played dual functions in catalyzing generation of center dot OH for CDT and O-2 for enhanced chemotherapy, while the solid lipid monostearin increased stability and tumor selectiveness of nanoparticles. Both in vitro and in vivo experiments confirmed the enhanced anticancer efficacy and biosafety of this nanomedicine.

Summary: The study investigated the treatment of organic pollutants using ZnO partially coated with different nonmetal layers (CeO2, Y2O3, PdO) through a photocatalysis process. The results showed that partial coating improved the photodegradation efficiency of ZnO, achieving complete degradation of BY28 and SMZ under UV irradiation. Furthermore, under visible light, ZnO/PdO degraded 94% of BY28 in 120 min and 60% of SMZ in 180 min due to effective separation of photo-induced charge carriers between PdO and ZnO.

Summary: In this study, innovative visible-light-driven nano-photocatalysts were explored for the accelerated activation of H2O2 and persulfate (PS) towards the degradation of ionic dyes in wastewater. Highly-defective yttria-layers (D-Y2O3) were customized and used for the stabilization of ZnO and Sm-doped ZnO (Sm-ZnO) nanoparticles. The Sm-ZnO@D-Y2O3 nanocomposite exhibited advanced surface area and porosity, significant surface heterogeneity, elevated negatively charged nanoparticles, large populations of oxygen vacancies, and enhanced visible-light absorptivity. The Sm-ZnO@D-Y2O3/PS/Vis system displayed superior degradation efficiency, near-complete mineralization performance, and great cyclability, making it an excellent candidate for the complete destruction of organic pollutants via a newly discovered photocatalytic mechanism.

Summary: The study investigates the killing efficiency of UV-C irradiation, dry heat, and steam sterilization against bacteria, fungi, and viruses on surgical masks and N95 respirators. Results show that after 5 cycles of steam, 10 cycles of dry heat, or 10 cycles of UV-C irradiation, the masks' performance remains unaffected.

Summary: The study introduces a easily synthesized plastic material with inherent antimicrobial activity, without releasing antimicrobial components. Bactericidal effects take place when bacteria come into contact with the material for a prolonged period, and scanning probe microscopy analysis revealed soft nanostructures on the submicron scale.
