Paramagnetic complexes of iron (III), manganese (II), and cobalt (II) protoporphyrins IX and apohemoproteins react with nitric oxide to form spectroscopically distinct compounds. Optical and electron paramagnetic resonance (EPR) studies suggest that a l-electron transfer between nitric oxides and metal ions which occurs in these reactions results in the formation of spin-paired complexes of the...

A fast and cost-effective technique is applied for fabricating cobalt and nickel nanopillars on aluminium substrates. By applying an electrochemical process, the aluminium oxide barrier layer is removed from the pore bottom tips of nanoporous anodic alumina templates. So, cobalt and nickel nanopillars are fabricated into these templates by DC electrodeposition. The resulting nanostructure remai...

We synthesized single-phase CoS2 on a large scale by adding graphene oxide of sufficient quantity via the hydrothermal method using cobalt acetate and thioacetamide as precursors; this produced the hybrid of CoS2 with reduced graphene oxide which exhibited high electrocatalytic activity in the hydrogen evolution reaction.

the application of conductive coatings on ferritic stainless steel can decrease electrical conductivity. theaim of this research was to investigate the electrical conductivity of cobalt coated aisi 430 ferritic stainlesssteel by pack cementation technique. coated coupons were analyzed using scanning electron microscopy(sem). electrical conductivity of the coated substrates was measured as a fun...

lithium-ion batteries due to their higher energy density and lower associated environmental impacts comparing to the other batteries, recently have been highly considered. the materials used in anode, are one of the most important parts affecting batteries’ energy density and environmental impacts. the aim of this study is to investigate how environmental emissions of different materials as ano...
