The interface zone thickness, which formed by intermixing and diffusion, was characterised by different techniques including STEM-EDS line scan, HRTEM and Atom Probe.
However, if the occupation probability is set to pc the ant displays 'anomalous diffusion', characterised by sub-diffusive movement [30].
In contrast, there is no theoretical reason to include this time constraint in the BB method, as it a priori assumes purely diffusive movements characterised by a diffusion coefficient that remains constant for the whole tracking period.
This diffusion chamber has been characterised numerically for the effect geometry has on equilibrium time, the concentration profile and the flow profile within the central chamber.
In all experiments a period of constant rate drying is observed, followed by a period of diffusion control that is characterised by a rapid increase in sample temperature.
In that study we characterised Knudsen diffusion (CK) and viscous flow (Cv) structural parameters, two of three parameters that constitute the viscous flow plus dusty gas model (VF+DGM) intrapellet flux equation for a macroporous pellet under adsorbing conditions.
A number of quantitative metrics can be obtained from diffusion MRI to characterise the tissue, including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) derived using the diffusion tensor model (i.e. Diffusion Tensor Imaging, DTI) [ 21].
The diffusion mechanism of the adsorption process is characterised using the intraparticle diffusion model because the pseudo-first and pseudo-second-order models are not applicable.
Cellular PCG is characterised by diffusion-coupling between cells of one phase and nearly plane front of the other under the constraint of mechanical equilibrium at the triple junction.
Moreover, from the analyses of the anodic current transients measured from both the film specimens, it was suggested that the cell-impedance-controlled constraint at the electrode surface is changed to the diffusion-controlled constraint simultaneously characterised by the large potential step and the small amount of lithium transferred during lithium transport.
