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 ...
Messages diffuse faster than messengers
(National Academy of Sciences, 2006-12)
In many cell-signaling pathways, information is transmitted by the diffusion of messenger molecules. Diffusion coefficients characterize the messenger's spatial range and the characteristic times of signal propagation. ...
Fluorescence correlation spectroscopy experiments to quantify free diffusion coefficients in reaction-diffusion systems: The case of Ca 2 + and its dyes
(American Physical Society, 2017-06)
Many cell signaling pathways involve the diffusion of messengers that bind and unbind to and from intracellular components. Quantifying their net transport rate under different conditions then requires having separate ...
Development of a Predictive Model for Polymer/Solvent Diffusion Coefficient Calculations

Salting kinetics, salt diffusivities and proximate composition in osmotically dehydrated Pirarucu muscle
(Univ Politecnica Valencia, 2018-01-01)
Pirarucu (Arapaima gigas Schinz) farming has been encouraged and, among meat preservation techniques, the salting process is a relatively simple and low-cost method. The objective of this work was to study the sodium ...
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- ...
