Molecular dynamics (MD) simulations offer a robust framework for predicting diffusion coefficients by bridging microscopic particle motion with macroscopic transport properties. At the heart of these ...

Bimolecular diffusion coefficients are important parameters used by atmospheric models to calculate altitude profiles of minor constituents in an atmosphere. Unfortunately, laboratory measurements of ...

We consider the problem of identifying an unknown diffusion coefficient in a nonlinear diffusion equation from overspecified data measured on the boundary. Conditions ensuring compatibility of the ...

This article shows how to determine moisture diffusion coefficients in polymer thin films by measuring adsorption isotherms on the thin films in a DVS instrument. Moisture diffusion in thin polymer ...

Proteins called cytokines that are secreted by cells within the lymph nodes are often used as drugs to manipulate immune responses. But something so basic as how these proteins travel through lymph ...

What is the Stokes-Einstein Equation? The Stokes-Einstein equation is a fundamental relation in physics that describes the diffusion of spherical particles through a fluid with low Reynolds number. It ...
