Small amounts of graphene and xGnP can be used in combination as a low-cost and effective improver for both the heat diffusion and shape-stabilization of paraffin PCMs.
However, when the dynamic balance between pm and pf is broken which exists in most coalbed methane engineering, the differences between the two pressures induced by gas diffusion and matrix shape factor will generate nonuniform matrix swelling which have not been well learned to date, thus influence the permeability evolution.
The trace images give valuable information about the magnitude of diffusion, and the shape of the diffusion tensor may change independently from the overall size or magnitude of the diffusion tensor.
In particular, the low-dimensional topological structure of social networks shapes the pattern of information diffusion, and the latter shapes the dynamics of the former.
Ebrahimi A, Or D. Hydration and diffusion processes shape microbial community organization and function in model soil aggregates.
Linking hypotheses about structural changes likely to occur during pyrolysis with the probe data provides insights regarding transformation of the random coil polyimide into ultra-rigid CMS, with exquisite size and shape diffusion selectivity.
We observed that the effect of molecular size and shape on diffusion is characterized by an effective molecular volume, Veff, instead of the liquid volume at 0 K. Veff is calculated from an effective molecular diameter which is obtained by applying a weighting function over the three dimensions of the solvent molecule.
In an accompanying report, fluorine-19 spin diffusion and fluorine-19 line shape data indicate larger morphological changes in Nafion upon addition of ethanol and greater plasticization of the pendant group domain.
The numerical results clearly demonstrate that M-CICSAM produces more accurate predictions on arbitrary meshes, especially at high Courant numbers, by reducing the numerical diffusion and preserving the interface shape.
The separation mechanism is mainly based on adsorption and diffusion enhanced by shape selectivity and size exclusion in some cases.
