... were measured at 25°C using a hand-made apparatus which can irradiate a microwave (2,450 MHz) to the membrane. Both the permeability and diffusion coefficients of CO2 for CA membranes are increased by irradiation of the microwave, and degree of enhancement increased with power of th ...

... and the free-volume theory. Mean hole volume probed by PALS was employed to predict the free volume available for solvent transport and solvent diffusion coefficient. The predictions of infinite dilution diffusion coefficients of four organic solvents in two common polymers were generall ...

... model and concentration dependences of membrane conductivity, the structural membrane heterogeneity was determined for 14 commercial IEMs. The diffusion coefficient, molar conductivity of counter-ions and hydration capacity of the gelphase were calculated and analyzed for cross-linked and linea ...

... values for structural (fractional void volume), electrical (fixed charge concentration and ion transport number) and diffusional (ionic and salt diffusion coefficients) parameters were obtained, and temperature effect on membrane diffusivity also seems to be related to RC content. Moreover, th ...
