Summary: In this study, Prussian blue analogs were prepared and calcined to obtain porous transition metal (Ni, Co, Fe) oxides (TMOs). The metal composition of the catalysts significantly influences their structures and catalytic properties. Among them, the NCF-TMO catalyst exhibits excellent photothermal catalytic performance, producing 2.9 mmol g-1 h-1 of CO and 1.6 mmol g-1 h-1 mmol of CH4 at low concentrations of CO2 and H2. The superior catalytic performance of the NCF-TMO catalyst is primarily attributed to the construction of heterojunctions between NiO, Co3O4, and Fe2O3, as well as the formation of abundant surface reactive active sites, facilitating efficient CO2 conversion. This study provides a promising direction for the utilization of CO2 resources.

Summary: Hybrid nanostructures of quaternary composite of transition metal oxides (QCTMO) were fabricated by sputtering silver oxide or chromium oxide nano-dots onto flower-like nanostructures of manganese-cobaltcopper (MCC) ternary metal oxide. Different plasma powers were used in the magnetron-assisted DC sputtering to fabricate QCTMO electrodes. The presence of four different multivalent metal ions increased redox sites, while the hybrid nature of the nanostructures increased the electrochemically active surface area. The electrode performance was enhanced by the synergistic effects. It was demonstrated that plasma power could control the morphology and electrochemical properties of QCTMO electrodes. The QCTMO electrode with chromium oxide nano-dots sputter deposited over MCC at 65 W showed the best performance, with a specific capacitance of 2261 F g-1 at a scan rate of 1 mV s-1 and a specific capacity of 603 C g-1 at 5 mA cm-2. A solid-state symmetric supercapacitor fabricated with this electrode exhibited a capacitance retention of 93% after 4000 charge-discharge cycles and a high energy density of 106 W h kg-1 at 3236.3 W kg-1 of power density.

Summary: New composite films were prepared by incorporating bacterial cellulose nanofibers and cerium oxide nanoparticles into chitosan matrices. The amount of nanofillers affected the structure and properties of the composites, including film stiffness and strength. Increasing the concentration of nanoceria improved the biocompatibility and adhesion of the films to mesenchymal stem cells. These nanocomposite films exhibit favorable properties for use as matrix materials in cell culture and wound dressings.

Summary: Nanocrystalline cerium dioxide is a promising inorganic UV filter for sunscreen applications due to its high UV absorbance and non-toxicity to normal cells. Nanoscale CeO2 also showed selective cytotoxicity to cancer cells. Crystalline cerium(IV) phosphates can be a promising alternative for nanoscale CeO2 due to their low solubility, high redox stability and UV protective property. In this work, it was demonstrated for the first time that ceric phosphates have a comparable inhibitory impact on murine melanoma B16/F10 cell line to nanoscale CeO2 at high concentrations.

Summary: This work investigated the physicochemical properties and biological activity of nanoemulsions prepared from paraffin oil and stabilized by nonionic surfactants as carriers of curcumin and cerium dioxide nanoparticles. The results showed that curcumin was incorporated into the oil droplets while cerium dioxide nanoparticles were adsorbed on the surface of oil droplets. The nanoemulsion droplet size did not exceed 100 nm. The nanoemulsions demonstrated no toxicity to mouse embryonic fibroblasts in vitro and after a single intraperitoneal injection to mice in vivo, indicating their potential as drug carriers for advanced biomedical applications.

Summary: This study investigates the combined use of cold argon plasma (CAP) and metal oxide nanoparticles for antibacterial treatment. The results demonstrate that the combination of CAP and redox-active metal oxide or metal fluoride nanoparticles effectively inhibits bacterial growth, damages DNA, and disrupts the cell wall. The combination of CAP and CeF3 nanoparticles shows the strongest antimicrobial effect on plasmid DNA, while the CAP and WO3 combination is most effective against bacterial genomic DNA. CeF3 nanoparticles exhibit strong antimicrobial and DNA-damaging properties for the first time.

Summary: Due to the interest in reducing the number of infectious agents on high-touch surfaces, antimicrobial and antiviral textiles have become popular. This study aimed to create antiviral textiles by spray-depositing nanoparticles onto the surface of polyester textiles and evaluating their antiviral activity against two coronaviruses. The results showed that one type of nanoparticle maintained its antiviral efficacy after deposition, while the other type lost its activity. Additionally, using copper for creating antiviral textiles was found to be impractical.
