BMC Clin Pharmacol. 2010;10:1-27. One can use this value of PS to estimate the "equivalent" thickness of the rat blood-adipose diffusion limiting barrier. The permeability is equal to: where D W is ...

Taylor Dispersion Analysis (TDA), or Taylor-Aris dispersion, is a technique for rapidly determining the diffusion coefficients of molecules. From the diffusion coefficient values, hydrodynamic radii ...

During a study of the diffusivity of sulphorhodamine G in the cortical apoplast of maize roots widely discrepant rates were found between different samples. In roots which had developed large ...

Principles of irreversible thermodynamics; Driving forces and fluxes for diffusion; Diffusion in the presence of stress; Diffusion from electrical potential gradients, thermal gradients, and ...

In order to develop new materials, material engineers need to be able to predict how fast impurity atoms diffuse, or spread, in a crystal over a range of temperatures. Using new computational ...

Introduction Tissue barriers function as “gate keepers” between different compartments (usually blood and tissue) and are created by specialised membrane-associated proteins, located at the lateral ...
