Dielectric features of neurotransmitters, gamma-aminobutyric acid and L-glutamate, for molecular recognition by receptors

Article Abstract:

Dielectric features of gamma-aminobutyric acid (GABA) and L-glutamate (Glu) in aqueous solution were investigated in detail, and the importance of dipole-dipole interaction of GABA and Glu with their receptors for molecular recognition is discussed. An explanation of how GABA and Glu are oriented in the correct direction, relative to their binding sites on their receptor, for initial stage of the molecular recognition process is provided.

Observation of equilibrium, nanometer-sized clusters of silver iodide in aqueous solutions

Article Abstract:

The thermodynamically stable clusters containing up to 10 or more silver iodide pair were observed in aqueous electrolyte solutions using ultracentrifugation and cryoelectron microscopy. These clusters are in equilibrium with an excess phase of solid AgI.

Evaluation of surface composition of surface-active water-alcohol type mixtures: A comparison of semiempirical models

Article Abstract:

Adsorption at planar liquid-vapor interface of surface-active binary mixtures is studied and three well-known models for the composition of surface phase were tested. Also, the phenomenological model predictions for water-alcohol systems are compared.
