Interactions of trimethylamine N-oxide and water with cyclo-alanylglycine
Article Abstract:
The osmolyte trimethylamine N-oxide (TMAO) is one of the family of compounds found in living systems that can stabilize biomolecular tertiary structures and intermolecular (super 1)H{(super 1)H} nuclear Overhauser effects between the protons of cyclo-alanylglycine and protons of solvent components in TMAO-water solutions are determined. It is concluded that the formation of solute-hydrated TMAO complexes with lifetimes longer than the rotational correlation time of the complex is most likely reason for the observed effects.

Molecular dynamics study of surfactant monolayers adsorbed at the oil/water and air/water interfaces
Article Abstract:
An investigation of the physical properties of monolayers of monododecyl diethylene glycol (C (sub 12) E (sub 2)) surfactants adsorbed at the oil/water and air/water interfaces by atomistic molecular dynamics (MD) simulations is carried out. The analysis demonstrates that the surfactant molecules show more extended conflicts with a resultant rise in the thickness of the monolayer in the presence of the oil medium, and that the hydrocarbons tails of the surfactants are more vertically oriented at the oil/water interface.

Conformational change of poly(ethylene glycol) near the critical point of isobutyric acid + water
Article Abstract:
New measurements of the kinematic viscosity, v, are reported as a function of temperature for a solution of isobutyric acid + water at the critical composition, to which poly(ethylene glycol) (PEG) was added at a concentration of 6.01 mg/mL. The data reveal that v decreases near the critical point, with a maximum in v at about 0.05 degrees Celsius above the critical temperature, [T.sub.c].
