Molecular dynamics calculations of the scattering of D2O from the glycerol surface at different collision energies are reported. The results for the trapping probabilities and energy transfer are in good agreement with experiments. The calculations demonstrate that the strong attractive forces between these two strongly hydrogen bonding molecules have only a minor effect on the initial collision dynamics. The trapping probability is influenced to a significant extent by the repulsive hard sphere-like initial encounter with the corrugated surface and, only at a later stage, by the efficiency of energy flow in the multiple interactions between the water and the surface molecules.

The dynamics of desorption of a small ion from the liquid-vapor interface of water is calculated using molecular dynamics trajectories and compared with several theoretical models which are based on a one-dimensional diffusion on the potential of mean force. The diffusion model is in reasonable agre
An extended Ilkovic diffusion-kinetic model is presented to quantify the dynamic surface tension of adsorbed surfactant measured from radially growing liquid drops (1). Competing effects of surfactant depletion due to interfacial stretching and surfactant replenishment from the bulk are described. T
The activity of lipase from Humicola lanuginosa was investigated at the cubic liquid-crystalline phase/water interface. For comparison, the activity of this lipase at an ordinary triglyceride / water interface was also determined. \(\mathbf{A}\) cubic phase was formed by monoolein and water, and tri
