Superficial self-diffusion coefficient in Ih-ICE
(Masaryk University, 2020-07)
The evolution of the grain boundary groove in a bicrystalline ice sample was studied in this work. The groove is formed by the intersection of the grain boundary with the free surface. The bicrystalline ice sample had an ...
Unbiased diffusion of Brownian particles on disordered correlated potentials
(IOP Publishing, 2015)
In this work we study the diffusion of non-interacting overdamped particles, moving on unbiased disordered correlated potentials, subjected to Gaussian white noise. We obtain an exact expression for the diffusion coefficient ...
Mutual Diffusion Driven NMR: a new approach for the analysis ofmixtures by spatially resolved NMR spectroscopy
We introduce a new approach for resolving the NMR spectra of mixtures that relies on the mutual diffusion of dissolved species
when a concentration gradient is established within the NMR tube. This is achieved by cooling ...
Mathematical Modeling of Hot-Air Drying of Osmo-dehydrated Nectarines
(De Gruyter, 2015-08)
The influence of osmotic pretreatment on nectarines with solutions of glucose syrup and sorbitol and subsequent dehydration at different temperatures (60°C, 70°C, or 80°C) was evaluated. The kinetics of moisture loss during ...
Kinetics of osmotic dehydration and air-drying of pumpkins (Cucurbita moschata)
(Elsevier B.V., 2007-10-01)
Kinetics of osmotic dehydration (OD) and effects of sucrose impregnation on thermal air-drying of pumpkin slices were investigated. A simplified model based on the solution of Fick's Law was used to estimate effective ...

The Shannon entropy as a measure of diffusion in multidimensional dynamical systems
(Springer, 2018-04)
In the present work, we introduce two new estimators of chaotic diffusion based on the Shannon entropy. Using theoretical, heuristic and numerical arguments, we show that the entropy, S, provides a measure of the diffusion ...
Effective force area and discharge coefficient for reed type valves: A comprehensive data set from a numerical studySurface de force utile et coefficient de décharge pour les soupapes à lamelles multiples: Un ensemble complet de données tirées d'une étude numérique
(2019-07-01)
Radial diffusers have been used as valve model to determine effective force area and discharge coefficient of the flow. A comprehensive data set of these parameters is lacking in the literature. Here, we present numerical ...
Diffusion behavior in Nickel–Aluminum and Aluminum-Uranium diluted alloys
(Elsevier Science, 2014-07)
Impurity diffusion coefficients are entirely obtained from a low cost classical molecular statics technique (CMST). In particular, we show how CMST is appropriate in order to describe the impurity diffusion behavior mediated ...
