Kinetic isotope fractionation between water vapor and liquid water or ice depends on the ratio of the diffusivities of the isotopic species in air, but there is disagreement as to the values of these ratios and limited information about their temperature dependence. We use state-of-the-art ...

The mechanism of drying and the diffusion of water in green (fresh), red and whole lentils (4.20–4.32 mm diameter and 2.20–2.30 mm thickness) were successfully interpreted and modelled by using Fick's law. The moisture content of fresh green lentil was 55 % and moisture content of the ...
摘要: Molecular dynamics simulation was used to study the diffusivity of water at low concentrations in two types of amorphous polyurethanes PU1 and PU2. PU…关键词:Polyurethane Water diffusivity Concentration dependence DOI: 10.1016/j.polymer.2012.04.056 年份: 2012 ...
aWhere the water or air originally present in the voids is able to leave the syetem quickly, as for example in the case of a coarse-grained soil with large voids between the particles,then such volume changes are not a great problem, since full settlement can be achieved by readily ...

The reference gas is used to determine a relationship between the concentration of hydrogen and an output signal of a detector 8. Then, a molten metal sampler is housed in a sample housing chamber 22, a drive screw 26 is operated running air of a carrier gas to crush the sample and a ...
Abbreviations: WLR, water-induced linear reductionGas diffusion in soil is governed by the gas diffusion coefficient (D-p) and its variation with air-filled porosity (epsilon). Accurate or an upper-limit (risk assessment standpoint) prediction of D-p(epsilon) is essential when carrying out gas...
Rotational and translational diffusion properties in water of nano organic carbon (NOC) particles collected from premixed laminar ethylene/air flames have been investigated using both time resolved fluorescence polarisation anisotropy (TRFPA) and fluorescence correlation spectroscopy (FCS). Insight into the ...
