Biocompatibility of transition metal-substituted cobalt ferrite nanoparticles

Abstract: Transition metals of copper, zinc, manganese, and nickel were substituted into cobalt ferrite nanoparticles via a sol–gel route using citric acid as a chelating agent. The microstructure and elemental compositions of the nanoparticles were characterized using scanning electron microscopy combined with energy dispersive X-ray spectroscopy. The particle size of the nanoparticles was investigated using particle size analyzer, and the zeta potentials were measured using zeta potential analyzer. The phase components of the synthesized transition metal-substituted cobalt ferrite nanoparticles were studied using Raman spectroscopy. The biocompatibility of the nanoparticles was assessed using osteoblast-like cells. Results indicated that the substitution of transition metals strongly influences the physical, chemical properties, and biocompatibility of the cobalt ferrite nanoparticles.

Chalcopyrite CuGaTe(2): a high-efficiency bulk thermoelectric material.

Abstract: CuGaTe_2 with a chalcopyrite structure demonstrates promising thermoelectric properties. The maximum figure of merit ZT is 1.4 at 950 K. CuGaTe_2 and related chalcopyrites are a new class of high-efficiency bulk thermoelectric material for high-temperature applications.
