The ordered island growth has been obtained by controlling the local atomic mobility and the length of the diffusion pathway of Ge atoms, by means of a correct choice of the growth parameters (annealing time and temperature).
A comparison of the kinetic parameters for different thickness values allows to indicate the same Li diffusion rate whatever the film thickness and the diffusion pathway does not correspond to the thickness but to the length of the edge (≈1 μm) of V2O5 platelets.
Evans, J. R., Kaldenhoff, R., Genty, B. & Terashima, I. Resistances along the CO2 diffusion pathway inside leaves.
Furthermore, the linked mesopores and macropores shorten the diffusion pathway and facilitate the ion transport, which bring about high rate performance and power density32.
Moreover, the micro-scale architecture of the devices results in a significant reduction of the mean ionic diffusion pathway between two microelectrodes.
For the all-trans stretched molecules, the pathway length is determined only by the length of the hydrocarbon chain.
The typical features of porous materials enable the long diffusion pathway and relatively low power density.
Thus, these approximations over emphasize the cellular diffusion pathway.
This hydration layer creates a diffusion pathway for the entrapped bioactives.
Then polymer swelling should also be taken into consideration because it may increase the length of the diffusion pathways, decrease the drug concentration gradients, and potentially decrease the drug release rate [ 15].
Finally, the origin to a suppression or distortion of the FLG and the Gerischer impedance was discussed and explored in relation to e.g. numerical simulations on the effect of a slightly distributed diffusion length in the FLG, due to different torturous diffusion pathways within the cathodes.
