In this work, we present a methodology to estimate the water diffusion coefficient of a clay slab during convective drying by hot air. This parameter was determined using a numerical method by minimizing the difference between the points of the experimental and simulated drying kinetics. The ...

摘要: Very shallow lagoons that are a few centimeters deep are common in the arid Andes of Northern Chile, Argentina, Bolivia and Perú. The dynamics of these lagoons are dominated by the water–sediment inte关键词: Diffusional mass transfer coefficient Wind-induced flow Very shallow lagoons ...
Magnetic resonance imaging (MRI) based diffusion tensor imaging (DTI) can assess white matter (WM) integrity through several metrics, such as fractional anisotropy (FA), axial/radial diffusivities (AxD/RD), and mode of anisotropy (MA). Standard DTI is susceptible to the effects of extracellular...
However, the diffusion coefficient of the membrane might change in response to varying aquaporin activity. Additionally, water flow is likely to increase the dispersivity of D2O through the apoplast, resulting in a greater apparent diffusivity of the apoplast. As the apoplast is more diffusive than ...
Objective To investigate the diffusion coefficient of water molecules using magnetic resonance(MR)diffusion weighted spectroscopy(DWS)with normal medical magnetic resonance device.Methods Two powerful diffusion gradient magnetic fields were applied before the second and after the third π/2 radio frequency ...
We performed a molecular dynamics simulation to calculate the self-diffusion coefficients of 1-Butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide and water in a water–ionic liquid mixture. We then compared the simulated self-diffusion coefficients of cation, anion and water molecules with expe...
The volume of the liquid water becomes significant and the pore space is decreasing, resulting in a reduced diffusion coefficient. Nevertheless, the diffusive moisture transport is still higher than the advective moisture transport. In sub-figure (f) and (m), a “broad” multi-layer water film...
Water can freeze into diverse ice polymorphs depending on the external conditions such as temperature (T) and pressure (P). Herein, molecular dynamics simulations show evidence of a high-density orthorhombic phase, termed ice χ, forming spontaneously fr
