Some of the most promising catalysts for water oxidation rely on crystalline and amorphous cobalt oxide nanoparticles. Density functional theory (DFT) calculations are routinely used to study the electronic and atomic structures of these materials as well as the thermodynamics and mechanisms of the electrochemical oxygen evolution reaction. The accuracy of these theoretical predictions has neve...

Cobalt manganese ferrite nanoparticles have application potential in the biomedical field, however there is limited information concerning the biological response. The aim of this work was to investigate the cytotoxic potential of cobalt-manganese ferrite nanoparticles in canine mastocytoma tumor cells (C2) and adipose-derived mesenchymal stromal stem cells (ASCs) cultured under a static magnet...

Cobalt ferrite (CoFe2O4) nanoparticles were synthesized and investigated as a catalyst in the reaction of nitrous oxide (N2O) decomposition. was by solid–phase interaction at 1100 °C preliminary mechanochemical activation roller-ring vibrating mill 400 °C. The characterized X-ray diffraction (XRD), synchronous thermal analysis (TG DSC) scanning electron microscopy (SEM). A low-temperature nitro...

In this report, functional one-dimensional (1-D) Pt-Co3O4 heterostructures with enhanced electrochemical properties were synthesized via colloidal polymerization of polymer-coated ferromagnetic cobalt nanoparticles (PS-CoNPs). Colloidal polymerization of dipolar nanoparticles into hollow metal-semiconductor nanowires was achieved via a consecutive galvanic replacement reaction between Co and Pt...

The pyrolysis of transition metal carboxylates into organically modified silica glass-ZrO2 hybrid sol-gel films yields composite materials containing cobalt oxide nanoparticles in various proportions. The particles have sizes ranging from 5 to 10 nm, and they are homogeneously dispersed in the final materials. A reaction temperature near 250°C results in translucent films that have good mechani...
