, Kunming 650091, China ? Central South University Press and Springer-Verlag Berlin Heidelberg 2010 Abstract: The microwave absorbing characteristics of basic cobalt carbonate, cobalt oxide (Co3O4), and the mixture of basic cobalt carbonate and cobalt oxide were investigated by means of microwave cavity perturbation, their temperature increasing curves were measured, and their ability to absorb......

College of Chemistry and Chemical..., the amorphous Co–B alloy grown on graphene oxide(Co–B@GO) exhibits a high specific capacitance of 460 F g-1, which is nearly 1.5 times greater than that of bare Co–B nanoparticles at 1 Ag-1......
there are investigations of F. thermophilum in gene level, there is no paper to report the genes forming intracellular iron oxide and cobalt oxide mineral or any similar genes forming magnetosome in F. thermophilum [12, 50-52, 56-58]. But it doesn’t mean that F. thermophilum has no genes that regulate iron oxide and cobalt oxide [59, 60], and it may be a new approach of biomineralization and still needs more......
