Application to Nettley''s measurements on H2-N2 mixtures removes an apparent discrepancy with the kinetic theory prediction of the composition dependence of the diffusion coefficient for this system.doi:10.1080/00268975900100251Saxena, S.C.Mason, E.A....
Besides, NH 2 ‐MIL‐125 (Ti)/6FDA‐durene mixed matrix membrane showed the highest diffusivity coefficient of 35.1 × 10 ?8 cm 2 /s, resulting in higher CO 2 /CH 4 selectivity of 37.1. In addition, the CO 2 plasticization resistance obtained for nonfunctionalized and amine‐functionalized...
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 ...
The equilibrium concentration and the diffusion coefficient of the sorbed gases were found to be strongly dependent on the LC phase state, gas type and gas pressure and temperature. Furthermore, the influence of gases on the phase transition temperatures of LCs and the reversibility of gas ...
The permeability data on polymers show that as the permeability of one gas increases, the permeability of other gases also increases. This is a consequence of the diffusion coefficient of the gases being related to the free volume or effective polymer pore size. The solubility constant ratio of ...
The meaning of DIFFUSION is the state of being spread out or transmitted especially by contact : the action of diffusing. How to use diffusion in a sentence.
also compared with those predicted theoretically from solvent viscosity by the relationships of Einstein, Eyring, Longuet-Higgins and Pople, Ree, Ree and Eyring, and Houghton, the purpose being to find a physical explanation for the observed variation of diffusion coefficient with solute molecule size...
Presentation of a New Method for Determination of Diffusion Coefficients of Gaseous Pollutants in Cladding Wall Materials Indoors The objectives of this study were (1) to develop a simple and rapid experimental method for directly measuring the diffusion coefficient (D), and (2) ... Gonalves, Jo...
The given diffusion coefficient equations are used to calculate the diffusion coefficient in solids, liquids, and gases. First in gases: Diffusion coefficient equation of gases. D is the diffusion coefficient A is an empirical coefficient equal to 0.001859 T is the temperature, M is the ...
Deviation plots are given for most of these systems. Almost every gaseous diffusion coefficient which was experimentally determined and reported prior to 1970 can be obtained from the annotated bibliography and table of gas pairs. A detailed analysis of experimental methods is given, and ...
