Research on the Diffusion of Vs55 Permeability in Rat Kidneys Based on Computer Tomography

open access: yesZhileng xuebao, 2020
Cryopreservation is the usual method for long-term preservation of natural and engineered tissues. However, homogeneous loading of tissues with CPAs constitutes one of the major hurdles in tissue cryopreservation.

A non-equilibrium thermodynamics model for combined adsorption and diffusion processes in micro- and nanopores

open access: yes, 2012
A non-equilibrium thermodynamics model able to analyze the combined effect of diffusion and adsorption in porous materials is proposed. The model considers the coupled dynamics of the diffusive phase, described by a diffusion type equation, and the ...

Self-diffusion and Cooperative Diffusion in Semidilute Polymer Solutions as measured by Fluorescence Correlation Spectroscopy

open access: yes, 2009
We present a comprehensive investigation of polymer diffusion in the semidilute regime by fluorescence correlation spectroscopy (FCS) and dynamic light scattering (DLS). Using single-labeled polystyrene chains, FCS leads to the self-diffusion coefficient

Determining the effective hydrogen diffusion coefficient in 100Cr6 [PDF]

open access: yesMaterials and Corrosion, 2020
AbstractIn the present study, the diffusion constant for hydrogen in hardened 100Cr6 was measured in permeation tests. The tests were conducted on samples of different thicknesses. The diffusivity of hydrogen was also measured in prestrained samples to study the influence of plastic strain on the diffusion rate.
