DBD Plasma Combined with Different Foam Metal Electrodes for CO2 Decomposition: Experimental Results and DFT Validations

CO2 reduction at transition metal electrodes

A detailed understanding of the mechanism of electrochemical reduction of CO2 to form hydrocarbons can help design improved catalysts for this important reaction. Density functional theory calculations were used here to model the various elementary steps in this reaction on transition metal surfaces, in particular Cu(111) and Pt(111). The minimum energy paths for sequential protonation by eithe...

Metal Foam and Finned Metal Foam Heat Sinks for Electronics Cooling in Buoyancy-Induced Convection

In this paper, we present our recent experimental results on buoyancy-induced convection in aluminum metal foams of different pore densities [corresponding to 5, 10, 20, and 40 pores per in. (PPI)] and porosities (0.89–0.96). The results show that compared to a heated surface, the heat transfer coefficients in these heat sinks are five to six times higher. However, when compared to commercially...
