Book 2014It also explains how these influences can be modified and tuned, e.g. through appropriate surface coatings, film thicknesses or pore diameters. ".Dynamics in Confinement." sums up the present state-of-the-art and introduces to the analytical methods of choice for the study of dynamics in nanometer-s

Understanding Organizational Web Usesimulation is that detailed spatially resolved information on structure and dynamics of the confined system is available. We determine the influence of the confinement on the dielectric relaxation and show that for this system the apparent glass transition temperature of a confined film is independe

Chun Wei Choo,Brian Detlor,Don Turnbullame of the linear response approach is independent of the film thickness down to several nanometers and identical to the bulk value. For polystyrene it was found the thermal glass transition temperatures can depend on the film thickness. This different behavior is not well understood till now and ne

For a different IL ([BMIM] [BF.]), it is observed that ionic mobility at lower temperatures is enhanced by more than two decad

Lillian Eby,Beverly Sinoway,Anthony Parisi we show that different aspects of the flow process of polymers in cylindrical nanopores can be investigated by means of Broadband Dielectric Spectroscopy, using a recently developed experimental approach, which employs highly ordered nanoporous media as nanofluidics cell.
