Determination of the diffusion coefficient of hydrogen ion in hydrogels.

The role of diffusion in chemical pattern formation has been widely studied due to the great diversity of patterns emerging in reaction-diffusion systems, particularly in H+-autocatalytic reactions where hydrogels are applied to avoid convection. A custom-made conductometric cell is designed to measure the effective diffusion coefficient of a pair of strong electrolytes containing sodium ions o...

Calculation of the Effective Diffusion Coefficient for Heterogeneous Media

1 Introduction In this paper we discuss the range of the applicability of our recent approach [1] for the effective diffusion coefficient (mobility) in two-phase systems, e.g. composite materials, porous media, polymer blends, matrices with inclusions. We derived the equation for D eff as a function of the partial diffusion coefficients of a defect (or probe particle) in inclusions, D 1 , with ...

Scale Dependency of the Effective Matrix Diffusion Coefficient

It has been recognized that matrix diffusion is an important process for retarding solute transport in fractured rock. Based on analyses of tracer transport data from a number of field tests, we demonstrate that the effective matrix-diffusion coefficient may be scaledependent and generally increases with test scale. A preliminary theoretical explanation of this scale dependency is also presente...

Experimental study of determining the discharge coefficient relationship of trapezoidal Piano Key Weirs and sensitivity of effective parameters in it

Piano Key Weirs, a developed scheme of labyrinth weirs. In this study, 36 trapezoidal Piano Key Weirs models were conducted in 360 different geometric and hydraulic conditions. Experiments were conducted in a 11 m long flume with a rectangular cross section of 49 cm width and 70 cm height in which the effect of dimensionless ratios on the discharge coefficient was investigated. The results show...

Understanding the time-dependent effective diffusion coefficient measured by diffusion MRI: the intra-cellular case

Diffusion Magnetic Resonance Imaging (dMRI) can be used to measure a time-dependent effective diffusion coefficient that can in turn reveal information about the tissue geometry. Recently a mathematical model for the time-dependent effective diffusion coefficient was obtained using homogenization techniques after imposing a certain scaling relationship for the time, the biological cell membrane...
