Solutions for a non-Markovian diffusion equation
(Elsevier Science BvAmsterdamHolanda, 2010)
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 ...
Calibration of boundary conditions correlated to the diffusivity of chloride ions: An accurate study for random diffusivity
(2022-02-01)
For reinforced concrete (RC) structures, the corrosion of the reinforced steel bars from chloride ions is a periodic risk. The chloride ions diffusion is governed by Fick’ laws, however, these equations can be applied under ...
MATHEMATICAL APPROACH OF DIFFUSION IN THE ELECTROCHEMICAL CONTEXT
(Soc Brasileira Quimica, 2016-04-01)
The aim of this study was to explain in detail the mathematical methods used to deal with diffusion equations, mainly for students and researchers interested in electrochemistry and related areas. Emphasis was placed on ...
SUFFICIENT CONDITIONS ON DIFFUSIVITY FOR THE EXISTENCE AND NONEXISTENCE OF STABLE EQUILIBRIA WITH NONLINEAR FLUX ON THE BOUNDARY
(TEXAS STATE UNIVSAN MARCOS, 2012)
A reaction-diffusion equation with variable diffusivity and non-linear flux boundary condition is considered. The goal is to give sufficient conditions on the diffusivity function for nonexistence and also for existence ...
Taylor dispersion technique for investigation of diffusion in liquids and its applications.

Coordinate and time-dependent diffusion dynamics in protein folding
(Academic Press Inc. Elsevier B.V., 2010-09-01)
We developed both analytical and simulation methods to explore the diffusion dynamics in protein folding. We found the diffusion as a quantitative measure of escape from local traps along the protein folding funnel with ...
Chloride diffusion assessment in RC structures considering the stress-strain state effects and crack width influences
(2019-03-20)
The aim of this study is to investigate the chloride ions diffusion in sound and cracked concrete under compressive loads. The model includes the analytical setup and data analyses. The governing equations are modified to ...
Isothermal sintering kinetic of 3YTZ and 8YSZ: Cation diffusion
(Elsevier, 2013-01)
We have studied the sintering kinetic of 3 and 8 mol% of yttria stabilized zirconia under isothermal conditions. Sintering was performed in the temperature range between 1200 and 1450 °C. The sintering kinetic process was ...
Diffusion Signal in Magnetic Resonance Imaging: Origin and Interpretation in Neurosciences
