of the diffusion coefficient and the type (Fickian or non-Fickian) were precisely calculated by fitting of the proposed model to the literature experimental data. According to this modeling approach, the diffusion coefficient has no constant value and reduces over...

A direct semi-empirical inversion method has been developed that allows one to obtain a non-parametric potential from exptl. data. The method is iterative and converges rapidly once a good choice has been made for the ...

of 300, 400, 500 and 600 K. The order of calculated self-diffusion coefficient of SO2 guest molecules at different temperatures, is in the range of 10-9 up to 10-8 m2s-1. Overall rate for cage to cage diffusion shows an Arrhenius temperature dependence...

The pair potential energy function of He-Ne has been detd. using inversion of the exptl. reduced viscosity collision integrals obtained from the corresponding-states correlation. A comparison of the potential with the ...

on the release of diacetyl from colloidosome, but temperature had no significant effect on the release profile. A diffusion equation was fitted to the experimental data, and diffusion coefficients of 0.025 × 10−15 to 8.15 × 10−15 m2/s were obtained for diacetyl...

concentration decreased diffusion coefficient of liposomal structure. Moreover, cholesterol addition contributed to reduction of collective diffusion coefficient in the presence of PEG polymer. The SAXS experiment showed that the size and interaction...

increased. Release of nisin was faster at higher concentrations, and the diffusion coefficients increased significantly with increasing concentration. The partition coefficient -k- values obtained were 1.42, 0.61 and 0.64 for 3000, 5000 and 10,000 IU...

steel fixture. Diffusion heat treatments were performed at 550, 575, 600, 625, 640 and 650 °C. Microstructural observation and EPMA were employed to find the impurity diffusion coefficient of aluminum through TiAl3 and the kinetics of TiAl3 formation...
