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 ...
Development of a Predictive Model for Polymer/Solvent Diffusion Coefficient Calculations

Spatial distribution of solutes and water in sucrose solution dehydrated apples
(Taylor & Francis Inc, 2005-01-01)
Half-fresh apples were immersed in sucrose solution (50% w/w, 27 degrees C) during different times of exposition (2, 4, and 8 h). Then each fruit was sliced from the transversal exposed surface. Density, water, and sugar ...
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 ...
Configuration-dependent diffusion can shift the kinetic transition state and barrier height of protein folding
(Natl Acad Sciences, 2007-09-11)
We show that diffusion can play an important role in protein-folding kinetics. We explicitly calculate the diffusion coefficient of protein folding in a lattice model. We found that diffusion typically is configuration- ...
Analysis of Operating Conditions on Osmotic Dehydration of Plums (Prunus Domestica L.) and 3D-Numerical Determination of Effective Diffusion Coefficients
(De Gruyter, 2017-11)
The objective of this work was to analyze the relevant process conditions on osmotic dehydration of plums and to determine the diffusion coefficients related to this process. The influence of solution (type and concentration ...
Effective diffusion coefficients behavior in osmotic dehydration of apple slices considering shrinking and local concentration dependence
(Blackwell Publishing, 2008-04-01)
The mass transfer during osmotic dehydration of apple slices immersed in 40, 50 and 60% (w/w) aqueous sucrose solutions was investigated to evaluate the influence of solution concentration on diffusivities. In the mathematical ...
Messages Do Diffuse Faster Than Messengers: Reconciling disparate estimates of the morphogen Bicoid diffusion coefficient
(Public Library Of Science, 2014-04)
The gradient of Bicoid (Bcd) is key for the establishment of the anterior-posterior axis in Drosophila embryos. The gradient properties are compatible with the SDD model in which Bcd is synthesized at the anterior pole and ...
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 ...
