Knudsen Gas in a Finite Random Tube: Transport Diffusion and First Passage Properties
(SpringerNew YorkEUA, 2010)
Description of self-diffusion coefficients of gases, liquids and fluids at high pressure based on molecular simulation data
(Elsevier Science, 2006-04)
The purpose of this work is to evaluate the potential of modeling the self-diffusion coefficient (SDC) of real fluids in all fluid states based on Lennard-Jones analytical relationships involving the SDC, the temperature, ...
DIFFUSION-COEFFICIENTS OF AQUEOUS PHENOLS DETERMINED BY THE TAYLOR DISPERSION TECHNIQUE - EVIDENCE FOR SOLUTE ADSORPTION ON THE WALLS OF TEFLON TUBING
(Royal Soc ChemistryCambridgeInglaterra, 1993)
Diffusion of Sn in different purity α-Ti
(Elsevier Science, 2003-05)
The diffusion of Sn in the hcp (α) phase of high purity (99.99%) and pure (99.9%) Ti was studied at different temperatures from 873 up to 1100 K. The Rutherford Backscattering Spectrometry (RBS) technique was used to obtain ...
Mechanistic understanding of food effects: water diffusivity in gastrointestinal tract is an important parameter for the prediction of disintegration of solid oral dosage forms
(American Chemical Society, 2013-04)
Much interest has been expressed in this work on the role of water diffusivity in the release media as a new parameter for predicting drug release. NMR was used to measure water diffusivity in different media varying in ...
Self-assembled films from WO(3): Electrochromism and lithium ion diffusion
(ELSEVIER SCIENCE INC, 2010)
WO(3)/chitosan and WO(3)/chitosan/poly(ethylene oxide) (PEO) films were prepared by the layer-by-layer method. The presence of chitosan enabled PEO to be carried into the self-assembled structure, contributing to an increase ...
A Symbiotic Self-cross Diffusion Model
(Khayyam Publishing, 2014)
Diffusion calculations with two atomic models in h.c.p Zr-Nb diluted alloys
(Elsevier Science Sa, 2017-08)
In this work we perform a comparison of atomic diffusion multi-frequency models for h.c.p. lattices. Specifically, in diluted h.c.p. αZr-Nb alloy, we calculate, the tracer self- and impurity diffusion coefficients, with ...
Effect of self-stratification on sediment diffusivity in channel flows and boundary layers: a study using direct numerical simulations
(European Geosciences Union, 2014-08-06)
Sediment transport in nature comprises of bedload and suspended load, and precise modelling of these processes is essential for accurate sediment flux estimation. Traditionally, non-cohesive suspended sediment has been ...
