Diffusion, the Diffusion Coefficient, and Mechanisms of Diffusion
1970Diffusion is the way in which matter is transported through matter. It occurs by approximately random motions of the atoms in a crystal lattice. The net result of many such random movements of a large number of atoms is actual displacement of matter, the movement being activated by the thermal energy of the crystal.

Some Aspects of the Theory of Diffusion and Diffusers
The Journal of the Acoustical Society of America, 1969Fundamental theoretical considerations strongly imply that the degree of diffusion of a sound field in a reverberation room can be satisfactorily defined only when the degree of averaging (over either space or frequency, or both), inherently present in whatever measurement is under consideration, is included explicitly in the definition.

Diffusion, Chemical Reaction and Facilitated Diffusion
1972Investigators of transport phenomena in membranes have long been interested not only in the permeation or diffusion of one particular substance as such but also in its possible reaction with a carrier which may lead to facilitated diffusion of the substance across the membrane.

Diffusion coefficient in photon diffusion theory
Optics Letters, 2000The choice of the diffusion coefficient to be used in photon diffusion theory has been a subject of discussion in recent publications on tissue optics. We compared several diffusion coefficients with the apparent diffusion coefficient from the more fundamental transport theory, D(app).

This chapter contains a study of diffusion among political protests in Europe. We start from a theoretical perspective that assumes protests as inherently interdependent across countries. Hence, we link geographical proximity to the likelihood of protests and we apply a spatial panel data analysis to study this link at the European, regional and cross ...

This article treats the problem of the sharp front observed when a diffusing substance interacts irreversibly with binding sites within the medium. The model consists of two simultaneous partial differential equations that are nonlinear and cannot be solved in closed form.
