You dip your teabag into a cup of boiling water and watch the clear steaming liquid slowly change into an inviting rich red. The laws by which the particles of tea spread from the source of high ...
New fundamental physics research provides insights on the process of diffusion in complex systems such as living organisms. This new theoretical framework has broad implications for active surfaces, ...
IN work described elsewhere 1 we showed how to understand the steady-state transport of oxygen through hæmoglobin solution by the application of Fick's law of mass transport. The oxygen flux was shown ...
