Using periodic slab density functional theory, we investigate CO adsorption, diffusion, and dissociation energetics on a monolayer of Al covering Fe(100) [Al/Fe(100)]. We predict a weakly chemisorbed state of CO to exist on Al/Fe(100), with CO adsorbing on the 4-fold hollow site in a very tilted fashion. This state is predicted to have an extremely low CO stretching frequency of only 883 cm(-1)...

In the present study emission performance of a diesel engine (Lister Petter) was evaluated at different compression ratios and engine loads with soybean methyl ester and its 25%, 50%, 75% blends with diesel fuel at constant speed 1500 rpm. Exhaust emissions included CO, CO2, HC and NOx. The compression ratio and engine load varied from 14 to 20 with an interval 1 and 25 to...

background diatomite coated by nanoparticles of copper and zinc mixed oxides were used to investigate catalytic oxidation of carbon monoxide. objectives aim of this paper was to investigatediatomite performance as a supporting host to confine the cuo and zno nanoparticles and its catalytic activity for carbon monoxide oxidation. materials and methods the prepared catalysts were characterized by...
