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...

Cobalt chromite (CoCr2O4) with normal spinel structure, shows catalytic activity for oxidation of unburned methane in the natural gas vehilcles (NGV). In this study, CoCr2O4 nanoparticles were synthesized through a conventional co-precipitation technique and investigated for the catalytic combustion of methane. Cobalt nitrate hexahydrate,...

The extremely rich variety of functional properties of complex oxides, and the excellent crystal matching they can present, allows the design of a new electronics involving only oxides. The new devices could be revolutionary compared to the silicon-based ones, in part because the much superior behavior of some physical properties, but also due to the fact that some of these properties can be co...

In 1865, James Clerk Maxwell proposed four equations governing the dynamics of electric fi elds, magnetic fi elds and electric charges, which are now known as Maxwell’s equations1. Th ey show that magnetic interactions and motion of electric charges, which were initially thought to be two independent phenomena, are intrinsically coupled to each other. In the covariant relativistic form, they re...
