Effects of cyclodextrins on drug delivery through biological membranes.
TL;DR: The nature of secondary equilibria and competition between cyclodextrins and rheologically important biopolymers such as mucin are assessed to give a complete picture of the effect of these starch derivatives.

TL;DR: In general, negligible amounts of aggregates are formed in pure CD solutions, but the aggregate formation is greatly enhanced on inclusion complex formation, and the extent of aggregation increases with increasing CD concentration.

Free Volume and Entropy in Condensed Systems III. Entropy in Binary Liquid Mixtures; Partial Molal Entropy in Dilute Solutions; Structure and Thermodynamics in Aqueous Electrolytes
Henry S. Frank,Marjorie W. Evans +1 more
TL;DR: The first and second papers in this series, which make it possible to interpret entropy data in terms of a physical picture, are applied to binary solutions, and equations are derived relating energy and volume changes when a solution is formed to the entropy change for the process as discussed by the authors.

Molecular segregation observed in a concentrated alcohol–water solution
TL;DR: In this article, the authors used neutron diffraction with isotope substitution to probe the molecular-scale structure of a concentrated alcohol-water mixture (7:3 molar ratio) and found that most of the water molecules exist as small hydrogen-bonded strings and clusters in a 'fluid' of close-packed methyl groups, with water clusters bridging neighbouring methanol hydroxyl groups through hydrogen bonding.

TL;DR: The x-ray emission spectroscopy results provide a new explanation for a smaller entropy increase in the solution due to water molecules bridging methanol chains to form rings.

TL;DR: An extensive series of neutron diffraction experiments and molecular dynamics simulations has shown that mixtures of methanol and water exhibit extended structures in solution despite the components being fully miscible in all proportions, and the observed concentration dependence of several material properties of the solution may have a structural origin.
