Diffusion coefficients were measured for the ternary system 伪-cyclodextrin(I)- n -butylurea(2)-water at three average concentrations. The cross coefficient D 12 was found to be almost zero and D 21 large and negative. These results are in agreement with the presence of an inclusion complex ...
Diffusion coefficients were measured for the ternary system α-cyclodextrin(I)- n -butylurea(2)-water at three average concentrations. The cross coefficient D 12 was found to be almost zero and D 21 large and negative. These results are in agreement with the presence of an inclusion complex ...

The Darcy permeability is similar to the diffusion coefficient, which represents the viscous resistance of a solid material to fluid flow under a pressure gradient, and is related to the microstructure of the solid skeleton and the viscosity of the fluid. ...
Intradiffusion coefficients for tritiated water ( 3 HHO) and perchlorate ion ( 36 ClO 4 - ) were measured in perchloric acid solutions. At 5°C the diffusion coefficient measured for the tritiated species increases to a maximum near 1.3 mol-dm 3 . The data at 25°C have been used to ...
The self‐diffusion coefficient of water has been measured by the steady‐gradient spin‐echo method at pressures up to 2380 bar and temperatures between 2 and −20°C in the stable liquid range using both strengthened glass and beryllium–copper pressure vessels. At low temperatures and high ...
The mutual diffusion coefficient of aqueous sodium octanoate is compared with previously reported intradiffusion coefficients for sodium and octanoate ions. 展开 关键词: enthalpies of solution liquid alloys Cu-V Cu-Cr thermochemistry DOI: 10.1021/je950234b 被引量: 29 ...
The diffusion rate of noble gases in water has been measured by the mass‐spectrometrical determination of the amount of noble gas diffused in a certain time through a water column of known size. For Xe the absolute value of the diffusion coefficient was measured; for the other noble gases ...

Below the fiber saturation point, moisture movement occurs by water vapor diffusion in the cell cavities and pit system openings, and by bound water diffusion in the continuous cell wall, the cross wall, and the pit membrane. The coefficient of water vapor diffusion in wood, which can be ...
