MgO as promoter for electrocatalytic activities of Co3O4-MgO composite via abundant oxygen vacancies and Co2+ ions towards oxygen evolution reaction

Abdul Jaleel Laghari et al.

Summary: The Co3O4-MgO (CM) composite was synthesized by wet chemical method, which showed efficient oxygen evolution reaction (OER) due to the abundant oxygen vacancies and Co2+ concentration. Although MgO was inactive towards OER, it facilitated the formation of oxygen vacancies and Co2+ ions, accelerating OER kinetics. Physical studies and analytical techniques were used to investigate the morphology, crystalline structure, surface information, and chemical composition of the CM composite. The optimized CM-0.1 composite exhibited lower overpotential and higher electrochemical activity, indicating its enhanced OER performance.

Unveiling the nanotoxicological aspects of Se nanomaterials differing in size and morphology

Hana Stepankova et al.

Summary: Although the general concept of nanotechnology relies on exploiting the size-dependent properties of nanoscaled materials, the relationship between the size/morphology of nanoparticles and their biological activity is still not well understood. In this study, we investigated the biological activity of Se nanoparticles with different morphologies (nanorods vs. spherical particles) and aspect ratios (AR) in human cells and mice. Our findings suggest that the aspect ratio is a critical factor for the cytotoxicity and biocompatibility of nanorod-shaped Se nanomaterials.
