A Random First Order Theory of Liquid -Glass Transition
… law, stretched relaxations, deviations from the Stokes-Einstein relation in hydrodynamics, and aging have been observed in the laboratory. In this thesis, a microscopically motivated theory of glassy dynamics based on an underlying random first order transition is developed to explain the …

Cation and Anion Transport in a Dicationic Imidazolium-Based Plastic Crystal Ion Conductor
… values for this class of OIPCs and the Stokes-Einstein relation, we propose that ion conduction is dominated by anion diffusion between crystallites (i.e., grain boundaries). Using our experimentally determine diffusion coefficient and previously reported PF6- hydrodynamic radius (rH), …

An experimental investigation of the motion of flexible molecules in the liquid state by light scattering
… reorientation times are interpreted using the Stokes Einstein relation. The Stokes Einstein volumes are interpreted as the quantity GapV where V is the molecular volume, alpha and p are associated with molecular shape and hydrodynamics and G with orientational correlation. An attempt is made to …

Microrheology and microstructure of poly(vinyl alcohol)-based physical gels
… from the depression of the intensity autocorrelation function of the scattered light. We find that gelation of the PVA/PEG blends is induced by the growth of aggregates in the blends. By comparing the gel point determined by light scattering to that from the rheometry, we find that the …

Dynamics Of Biopolymers On Nanomaterials Studied By Quasielastic Neutron Scattering And Mdsimulations
… MD Simulation results showed that the failure of Stokes Einstein relation results the presence of dynamic heterogeneities in the biomacromolecules. Radial pair distribution function from MD Simulation confirmed that the hydrophilic nature of ND attracts more water than RNA results the …

Single-Particle Orbit Tracking - Setup, Characterisation and Application
… published (publication P2). By the use of the Stokes-Einstein relation the diffusion coefficients could further be converted to particle radii. A closer examination of these radii emphasises the influence of the afore mentioned number of fitting points. For the optimal value, significantly …

Multiscale Transport and Dynamics in Ion-Dense Organic Electrolytes and Copolymer Micelles
Understanding molecular and ion dynamics in soft materials used for fuel cell, battery, and drug delivery vehicle applications on multiple time and length scales provides critical information for the development of next generation materials. In this dissertation, new insights into transport and …
