The mutual diffusion coefficient D as a function of penetrant concentration has been determined from the steady-state behavior, and compared with D a. D a is almost independent of the penetrant concentration, especially at higher temperatures, whereas D increases with increasing concentration, even ...

Small variations in temperature of the evaporating liquid have a very strong influence, especially at higher evaporation rates. The diffusion coefficient of water vapor in air is determined at 323, 333, and 343 K.doi:10.1007/978-1-4757-0725-0_8K. M. Dijkema...
The experimental measurement of the moisture diffusion coefficient by the steady-state method makes use of a diffusion cup. Water or a saturated salt solution is placed inside the cup to maintain the desired water vapor pressure on one side of the wood specimen that is used to cover themouthof...

The interaction of cellulose paper with water is a major hindrance to its broader application. This study, which introduces a novel approach to understand water vapor diffusion in both untreated and treated paper, aims to identify the diffusion coefficient, a crucial property in improving the ...

The increase in the diffusion coefficient of water trapped in CNTs was connected to this ultralow friction41,43, which was further correlated with nanotube curvature inducing incommensurability effects between the filling molecules and the nanotube27. More recently, it was shown that coupling between...
of view,Dγ≠f(t), which in this work we can establish asnormal time-scale. Other time-scale considers the burn up and depletion of nuclear fuel where, in general, the diffusion coefficient is function of timeDγ=f(t)with the aim to predict well the long-term changes in the reactor ...
On the basis of experimental measurements of the diffusion coefficient of H2(g) on cement pastes, Thiery et al. [5] have suggested other values for “a” and “b” (a = 2.74 and b = 4.2). They estimate that the convective contribution of the vapor phase in the modeling of the ...
