(a) Self-diffusion coefficient of water (D) nanoconfined in defected zeolite crystals.
On the one side, the self-diffusion coefficient of water in defected MFI is predominantly determined by water zeolite interactions (Ewz) at low hydrations (Eww).
(b) Self-diffusion coefficient of water nanoconfined in MFI zeolites with various defect concentrations versus water water-specific interaction energies (Ewater water-specificy Equatinteraction
The diffusion coefficient of water was calculated for polymer concentrations up to 10%.
The condensation coefficient of water is at least 0·7 and could easily be 1·0.
The diffusion coefficient of water in thin and ultra-thin plasma polymer films could be quantified for the smooth films.
The activity coefficient of water was found to have a strong influence on the agreement with experimental data.
Therefore, the average diffusion coefficient of water in treated PHDDT film was lower than that in untreated one.
The coefficient of water permeability of LSHCC was comparable with reference normal concrete and the engineered cementitious composite (ECC-M45) in the literature.
The impacts of cooling velocity and grain orientation on effective diffusion coefficient of water vapor, D, in dried wood were investigated.
The calculation of the diffusion coefficient of water leads to a value of 2.9*10−12 m2 s−1 in the studied system.
