AN ANALYTICAL SOLUTION FOR DIFFUSION AND NONLINEAR UPTAKE OF OXYGEN IN THE RETINA
A simple mathematical model of steady state oxygen distribution subject to diffusive transport and non- linear uptake in a retinal cylinder has been developed. The approximate analytical solution to a reaction- diffusion equation are obtained by using series expansions. The computational results for the scaled variables are presented through graphs. The effect of the important parameters (1) d...
متن کاملSingle walled carbon nanotube in the reaction layer of gas diffusion electrode for oxygen reduction reaction
In this paper, the effect of surface area of reaction layers in gas diffusion electrodes on oxygen reduction reaction was investigated. For this purpose, various amounts (0.1, 0.2, 0.3, 0.4, 0.5, 1, 1.5 and zero %wt of total loading of reaction layer) of single walled carbon nanotube (SWCNT) were inserted in the reaction layer. The performance of gas diffusion electrodes for oxygen reduction re...
متن کاملOxygen Diffusion in YBa
The oxygen diffusion in Y B a X u j O ^ , , was studied between 300 K and 1273 K in flowing oxygen by monitoring the 1 3 Ba(EC) Cs nuclear quadrupole interaction by time differential perturbed angular correlation. The data are analyzed in a model of two different nearest neighbour oxygen configurations and yield hopping rates, the energy barrier and the difference in free enthalpy between both ...

متن کاملMolecular Simulation of Oxygen Diffusion in Polymers
Oxygen diffusion in polymer membranes has great significances on the choice of packaging materials. In this work, molecular dynamics simulations and Grand canonical Monte Carlo were used to study the diffusion of oxygen in polymer membranes. It is found that the diffusion coefficient of oxygen in polymer membranes increases as the temperature increases. And the diffusion coefficient of oxygen i...
