Strategies for evaluating thermodynamic properties of lattice mixtures of differently-sized particles and chain molecules: application to partitioning data involving alkanes
Article Abstract:
The treatment of thermodynamic properties of lattice mixtures of differently sized particles and chain molecules by means of simple approximate strategies was described. Expressions for chemical potentials and partition coefficients were derived based on these strategies. These expressions account in a simple way for effects of particle size and chain length. The resulting expression for chemical potential reduces to the Flory-Huggins treatment the limit of long chains and single-cell solute molecules.

Simple lattice model for solvation of nonpolar molecules in hydrogen-bonded liquids
Article Abstract:
A lattice model that gives closed-form expression for solvation thermodynamic parameters in hydrogen-bonded solvents including water and alcohols is presented. The model allows one to handle the size of solutes in a very simple way with the help of a single parameter and accounts for the influence of the solute on the entropy of the solvent hydrogen bond network.

Phytosphingosine and sphingosine ceramide headgroup hydrogen bonding: Structural insights through thermotropic hydrogen/deuterium exchange
Article Abstract:
The IR spectroscopic studies are reported for phytoshingosine class of ceramides and are compared with two analogous sphingosine ceramides. The study reveals that the relative contribution of chain packing and H-bonding differs markedly for the phytosphingosines compared to the sphingosines.
