Sentence examples for molecular diffusion was from inspiring English sources
Therefore, the direction of molecular diffusion was completely parallel to the membrane.
A modified version of the free-volume theory designed to address molecular diffusion was evaluated over a wide temperature range.
The contribution of longitudinal molecular diffusion was negligible at gas velocities greater than 150 cm min−1.
In this study, a refined digital model of the pore structure of tight sandstone reservoirs was built using advanced digital core technology (Guo et al. 2016; Chen et al. 2015; Liu et al. 2014, 2017; Ni et al. 2017; Yin et al. 2016), and a numerical simulation of molecular diffusion was conducted on the basis of the model.
The DNA solution was delivered into the circular duct with two equal flow rate fluid delivery lines, with a very small Reynolds number in the range of 0.326 × 10−3 to 1.87 × 10−3, in which molecular diffusion was a major mechanism for mixing.
A cellular automaton method that includes a fabricating model for solvent casting/porogen leaching and a multiple-particle random walk model for oligomer molecular diffusion was used to simulate degradation behaviors and their dependence on the initial porosities (80%, 90 % and 95) of porous polylactide (PLA) scaffolds.
The often tacit assumption that they travel along the genome by molecular diffusion is doubtful, as molecules that have to diffuse randomly throughout the large and dense chromatin matrix may not provide a sufficiently fast and accurate genomic search mechanism.
A scalar dispersion simulation confirms that the "patch" of fluid near the origin is slowly mixing on the diffusive time scale and is convected "unmixed" when the influence of molecular diffusion is still not pronounced (short times relative to Pe= 100).
Molecular diffusion is caused by collision between different component gas molecules.
Bentonite material has a very low permeability, and consequently molecular diffusion is the main mechanism of mass transport.
Both one-dimensional vertical advection and molecular diffusion are considered for aquitard transport.
