In
this work, we developed a general theoretical description of
ternary solutions of small molecules under a centrifugal field, from
which we obtained the centrifugation map (CMap) as a general tool
to understand observations or to predict composition profiles in centrifugal
fields of arbitrary strength. The theoretical formalism is based on
the classical density functional theory with established models for
liquid mixtures. Thermodynamics also yields a general criterion for
apparent aggregation. The strength of the CMap approach is illustrated
for a ternary model system where ethanol is a co-solvent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
