The diffusion coefficients as derived in Sect.
The diffusion coefficients are positive constants.
The proposed atomic mobility parameters can reproduce a great majority of experimental data, including impurity diffusion coefficients, tracer diffusion coefficients, intrinsic diffusion coefficients and interdiffusion coefficients.
The diffusion coefficients were determined using Fick's equation.
The measured rotational diffusion coefficients decrease with increasing particle size.
Two apparent diffusion coefficients or models are then obtained.
Bulk diffusion coefficients are estimated for several Cs impurity states.
Both static and frequency dependent diffusion coefficients have been evaluated.
The self-diffusion coefficients and solute diffusion coefficients in Fe host were derived using the nine-frequency model.
Parametric studies reveal effective diffusion coefficients in charged porous media exceeding the corresponding self-diffusion coefficients by up to 34%.
Let k j ( j = 1, 2 ) be BV diffusion coefficients.
