The kinetics and thermodynamics characteristics of Pb(II) and Cu(II) adsorption onto fly ash of a oil shale-fired power plant was investigated by using batch adsorption method. The results showed that Langmuir and Freundlich adsorption isotherms were applicable to the adsorption process, while Freundlich equation is more applicable. The mechanistic steps of the adsorption process was studied through...
Transition metal ion (V, Fe, or Cu) doped TiO2 nanoparticles were synthesized from titanium tetraisopropoxide (TTIP) in absolute ethanol by the modified sol-gel method. The precursor of the transition metal to be doped was added to an alcoholic solution containing TTIP. This solution was loaded into a pouch type cellophane membrane and placed in a clear solution containing 1:1 (v/v) ratio of absolute...
Surface effects from contaminants and oxidation will be investigated for gold and copper metallic nanowires. The objectives are to investigate effects from adsorption and diffusion of C and/or O and their effects on resistance. Also, the possibility of using gold as a diffusion barrier will be investigated as part of this research.
