Adsorption of diastereometrically pure sodium cis- and trans-(2-n-alkyl-1,3-dioxan-5-yl) sulfates at the n-heptane-water interface
Article Abstract:
A marked discrepancy between the rate of standard free energy of adsorption and micellization between cis- and trans-isomers was noted in an analysis involving diastereomerically pure sodium sulfates. Results revealed that the samples exhibited different lengths of alkyl chain, which in turn, generated lower values of energy adsorption and micellization for trans-isomers compared to their cis- counterparts. Despite such differences, it was stressed that both samples manifested relatively the same effectiveness of surface tension reduction.

Polarization spectroscopy of single fluorescent molecules
Article Abstract:
A study conducted polarization anisotropy investigations of single dipoles. The latest, novel, highly sensitive, single-molecule spectroscopic techniques were used to examine the polarization response of a single fluorophore. Results of such studies can yield insights into rotational dynamics on the single-molecule level that cannot be derived from conventional ensemble polarization experiments. The study also considered the possibility of using these novel methods to measure the conformational changes of biological macromolecules.

Influence of surface tension on adsorbate molecular rotation at liquid/liquid interfaces
Article Abstract:
Molecular dynamics computer simulations of a series of liquid/liquid interfaces with variable surface tension and fixed bulk viscosity are used to study the effect of the liquid surface on the rotational correlation time of a molecular solute adsorbed at the interface.
