Properties of the asymptotic nA + mB → C reaction - diffusion

چکیده
We discuss, at the mean-field level, the asymptotic shape of the reaction fronts in the general nA+mB → C reaction-diffusion processes with initially separated reactants, thus generalizing to arbitrary reaction-order kinetics the work done by Gálfi and Rácz for the case n = m = 1. Consequences for the formation of Liesegang patterns are discussed. PACS. 82.20.Mj Nonequilibrium kinetics – 82.20.Db Statistical theories – 66.30.Ny Chemical interdiffusion

متن کاملElectrocatalytic properties of platinum and it's binary alloy with vanadium in oxygen reduction reaction(ORR)
The electrocatalysis of the oxygen reduction reaction (ORR) on carbon supportedPt-V (1:1) catalyst in polymer electrolyte fuel cells (PEFC) was investigated. Atan oxygen pressure of one atm an enhanced electrocatalytic property of Pt-V/Ccompared with Pt/C is revealed. These results indicate the occurrence of adifferent electrocatalytic mechanism for the ORR on Pt/C and Pt-V/C. Anincrease of mas...
متن کاملEffect of diffusion bonding temperature on microstructure properties of Zr/Ti interlayer in the diffusion bonded joints of Zr702 to A516 steel
In this study, the effect of temperature on the microstructure and reactive layer at the interface between the Ti interlayer and the base metal related to the diffusion bonding of Zr702 to A516 low alloy steel was investigated. The joining was done using the spark plasma sintering technique at temperatures of 900, 950 and 1000°C for 30 minutes. Field Emission Scanning Electron Microscope (FESEM...

متن کاملThe effects of Na & Mg adsorption on the electrical properties of SiCNTs: A DFT study
In the present study we focused on the electronic and structural properties of Na and Mg adsorption on the surface of the (6, 6) armchair SiCNTs. The adsorption energy (Eads), band gap energy (Eg), partial density of state (PDOS), chemical potential (μ), global hardness (η), electrophilicity index (ω), global softness (S), work function values (φ) and work function change (Δφ) are calculated by...
