Simplified calculation of diffusivity for a lattice-based random walk with a single obstacle [PDF]

, 2017
Motion of cells in living tissues is hindered by obstacles, which may be stationary or may also move. We present a simplified method to calculate the exact Fickian diffusivity for a tracer particle in a random walk with one obstacle.

Sorptivity calculation for arbitrary diffusivity [PDF]

, 1994
An estimate of the sorptivity that requires only the knowledge of simple integrals of the soil-water diffusivity weighted by a power of the water content is present.

Thermal properties of vesicular rhyolite [PDF]

, 1994
Thermal diffusivity of rhyolite melt and rhyolite foam (70–80% porosity) has been measured using the radial heat transfer method. Cylindrical samples (length 50–55 mm, diameter 22 mm) of rhyolite melt and foam have been derived by heating samples of ...

Controls on cobalt concentrations in ferromanganese crusts from the Magellan seamounts, west Pacific

Frontiers in Marine Science
IntroductionCobalt is the most important critical element in ferromanganese crusts. Co concentration in the Fe-Mn crusts is one of the key parameters for determination of the Co resource. Thus, it is essential to clarify the controls on the variations of

Diffusivity and intrinsic diffusivity measurements on multicomponent alloys

, 1992
The diffusivity and intrinsic diffusivity of multicomponent alloys can be determined from diffusion couple experiments, when concentration differences in each diffusion couple are small, by using the Square Root Diffusivity analysis.
