Non-ideality in multicomponent diffusion of polyelectrolyte solutions

Non-ideality in multicomponent diffusion of polyelectrolyte solutions

Dispersive-diffusive transport of non-sorbed solute in multicomponent solutions

The composition of fuels, mixed-solvent wastes and other contaminants that find their way into the subsurface are frequently chemically complex. The dispersion and diffusion characteristics of multicomponent solutions in soil have rarely been compared to equivalent single-solute systems. The purpose of this work was to examine the diffusive and dispersive transport of singleand multi-component ...

On the non ideality of CO2 solutions in ionic liquids and other low volatile solvents

The nonideality of CO2 solutions in ionic liquids and other low volatile solvents, with which CO2 is known to form electron donor-acceptor (EDA) complexes, is here investigated. It is shown that the deviations from the ideality observed are not related with the stability of the EDA complex formed, and inmost cases these deviations are small and dominated by entropic effects. For this reason, wh...

Uphill diffusion in multicomponent mixtures.

Molecular diffusion is an omnipresent phenomena that is important in a wide variety of contexts in chemical, physical, and biological processes. In the majority of cases, the diffusion process can be adequately described by Fick's law that postulates a linear relationship between the flux of any species and its own concentration gradient. Most commonly, a component diffuses down the concentrati...
