Microscopic treatment of solute trapping and drag.
The long wavelength limit of a recent microscopic phase-field crystal (PFC) theory of a binary alloy mixture is used to derive an analytical approximation for the segregation coefficient as a function of the interface velocity, and relate it to the two-point correlation function of the liquid and the thermodynamic properties of solid and liquid phases. Our results offer the first analytical der...
متن کاملRole of solute drag in intestinal transport
This study presents experiments related to the role of solvent drag and solute drag in the transmembrane movement of nonelectrolytes in a perfused rat intestine preparation. Conditions were chosen to simulate the effects of luminal hyperosmolarity on the permeability of tracer solutes. Data are presented on net water flux, transepithelial potentials, and lumen-to-blood and blood-to-lumen tracer...
متن کاملAn experimentally quantifiable solute drag factor
An empirically determined measure of the solute drag force called the drag factor is derived and defined. The drag factor is the derivative of mobility with respect to grain size, and describes well the drag effect of solute in the six different aluminas measured. A normalized drag factor allows direct comparison of different dopants, and validation of theoretically predicted trends. This const...
متن کاملEffects of solvent and solute drag on transmembrane diffusion
The present study compares and quantitates both solvent drag and solute drag forces in a system with both heteropore and homopore membranes. It is shown that tracer solute permeability can be increased if solution flow or driver solute flux is in the direction of tracer diffusion. Either force can decrease tracer permeability if the force can decrease tracer permeability if the force is opposit...
متن کاملSolute trapping and solute drag in a phase-field model of rapid solidification
During rapid solidification, solute may be incorporated into the solid phase at a concentration significantly different from that predicted by equilibrium thermodynamics. This process, known as solute trapping, leads to a progressive reduction in the concentration change across the interface as the solidification rate increases. Theoretical treatments of rapid solidification using traditional s...
