The design and fabrication of a high-performance electrode material based on cobalt disulfide/reduced graphene oxide (CoS2/RGO) nanocomposites is reported by a one-step hydrothermal method.
A more practical substitute has been developed at the Massachusetts Institute of Technology, where Daniel Nocera and his colleagues have perfected cheap and durable catalysts based on cobalt and phosphate, and, more recently, on nickel and borate.
The method was used to determination of cobalt, copper and nickel in two sample alloys based on copper, nickel and cobalt (known as cunico) and based on cobalt, nickel and iron (known as conife).
Fischer Tropsch catalysts, based on cobalt, are complex materials containing the catalyst support and reduction and structural promoters in addition to the cobalt metal itself.
The work thus gives insight into the requirements for effective Lewis acidic epoxide ring-opening catalysts based on cobalt.
This is likely due to the higher oxidation resistance of these alloys compared to those based on cobalt.
We will also discuss potential applications of three-dimensional self-assembled photonic hypercrystals, which are based on cobalt ferrofluids in external magnetic field.
Recently, R. Jérôme and his coworkers reported a system based on cobalt acetylacetonate [Co acac 2] that imparts control to the radical polymerization of vinyl acetate initiated by 2,2'-azobis(4-methoxy-2,4-dimethyl valeronitrile), V-70, in the bulk at 30°C.
Previous studies regarding modular head-neck taper corrosion were largely based on cobalt chrome (CoCr) alloy femoral heads.
A novel sensing system has been designed for cobalt ion detection based on a cobalt ion improved chemiluminescence (CL) in N-bromosuccinimide(NBS -reduced carboNBS -reducedt (rcarbonH−) system.
