After this process, the diffusion tensor elements were estimated by solving the Stejskal and Tanner equation [23], [24], and then the reconstructed tensor matrix was diagonalized to obtain three eigenvalues (λ1, λ2, λ3) and eigenvectors.
On a time scale longer than the characteristic for segmental relaxation (α process) the diffusion properties of the whole chains appear.
After this process, the diffusion tensor elements were estimated by solving the Stejskal and Tanner equation [ 42, 43], and then the reconstructed tensor matrix was diagonalized to obtain three eigenvalues (λ1, λ2, and λ3) and eigenvectors.
8– 10 But regardless how the data are processed, the diffusion coefficient difference between compounds must be at least 30%%, 11 and only a hand full (three to four) different compounds can typically be measured.
Considering the effect of different parameters on the anomalous diffusion processes, we present the diffusion processes with several varied parameters in Figure 5.
Usually diffusion process dominates drug release kinetics because matrix degradation is a slower process than the diffusion.
The hydrogen diffusion process follows the diffusion equation ∂ C ∂ t = D ∂ 2 C ∂ x 2, (1).
This process facilitates the diffusion of scientific ideas into broader society (Bucchi 2008).
