Approximative data of isothermal diffusion coefficient at the same concentrations are equally given.
The grid promotes chemical production more effectively than the trip wires under the condition that the mass diffusion is at the same level between the two flows.
Inside the porous material, Na3V2(particlesticles are embedded in carbon matrix, thus forming facial electron channels and reducing Na+ ion diffusion distance at the same time.
The results of the optimization analysis show that higher current densities at the membrane/cathode interface are obtained in the PEM cathode and the interdigitated air distributor geometries that promote convective oxygen transport to the membrane/cathode interface and reduce the thickness of the boundary diffusion layer at the same interface.
In the region where all of the three deposition mechanisms, i.e. inertia, interception and diffusion, act at the same time, real deposition efficiency ηTID is not accurately expressed by ηT + ηI + ηD.
We have developed a thermal evolution model of comet PBorrelly, using a numerical code that is able to solve the heat conduction and gas diffusion equations at the same time across an idealized spherical nucleus ( De Sanctis et al., 1999, 2000; Capria et al., 2000; Coradini et al., 1997a,b).
Pressure increases slow down thermal decomposition by limiting gaseous by-product diffusion while at the same time facilitating the collapse of produced pores.
However, if a longer diffusion time at the same SNR could be achieved this might be advantageous for the current study.
GRiP represents a new and efficient implementation of the TF search process, which considers a highly detailed model of 1D diffusion and, at the same time, it simulates at least ≈4 times faster than previous software (Barnes and Chu, 2010; Chu et al., 2009).
