Concentration of the salts and the charge of metal ion on swelling behavior, composition and structure of the gels poly (PAMPS) salts in aqueous medium are studied. The existence of the reentrant conformational transition in the anionic PAMPS gel is due to the increase of concentration of trivalent metal cations in the solutions.

A numerical model based on a simultaneous solution to the Nernst-Planck, Poisson, and Navier-Stokes equations is used to examine the electroosmotically driven flow through a microchannel exhibiting a periodically repeating patchwise heterogenous surface pattern.

Crystal growth and fluorescent characteristics of a quinoline-capped thiophene oligomer is investigated in thin films grown on the (001) surface of KCl by a hot-wall epitaxy technique. The cis- and trans- configurations of the quinoline groups vary the electrostatic intermolecular interactions in the solid state.

A novel organic branched phthalocyanine (Pc) dendrimer system is found that allows impressive dielectric properties with very low loss at high operational frequencies. The mechanism of this high-frequency response with relatively small dispersion is suggested to be due to a long-range polaron hopping mechanism accompanied by strong intramolecular interactions in the branched systems.
