GLASSES CONTAINING COBALT OXIDE, III

Cobalt(III) complexes as functional ligands for metal (oxide) surfaces.

Co(III) polyamine complexes with either two or three labile coordination sites bind strongly to high surface area metal oxides such as goethite or aluminium trihydroxide, and have been shown to act as passivating agents for aluminium flake in aqueous media, in addition to providing a potential method for surface functionalisation.

Preparation and Study of Bismuth Oxide Doped and co-Doped with Cobalt(III) and Holmium(III) via Sol-Gel Method

In this research work the solid-solutions of (Bi2O3)1-x (Co2O3)x, [x= 0.05, 0.1] (1), (Bi2O3)1-x (Ho2O3) x, [x= 0.025, 0.05] (2), and (Bi2O3)1-x-y (Co2O3)x (Ho2O3)y</su...

Preparation of Cobalt Oxide/Zinc Oxide Nanocomposite

Cobalt Oxide/ Zinc Oxide nanocomposite was synthesized by dropwise addition ofCo(NO)3.6H2O and Zn(NO3)2.4H2O solutions to KOH solution at different temperatures followed bycalcination at 300ºC for 4 h. The morphology and structure of nanoparticles and the influence oftemperature on particle size were studied using scanning electron microscopy (SEM) and X-RayDiffraction (XRD). Minimum particle s...

Cobalt-containing bioactive glasses reduce human mesenchymal stem cell chondrogenic differentiation despite HIF-1α stabilisation

Bioactive glasses (BGs) are excellent delivery systems for the sustained release of therapeutic ions and have been extensively studied in the context of bone tissue engineering. More recently, due to their osteogenic properties and expanding application to soft tissue repair, BGs have been proposed as promising materials for use at the osteochondral interface. Since hypoxia plays a critical rol...
