181. Lattice Model of Living Polymerization I. Basic Thermodynamic Properties
Published: 10/1/1999
Authors: J Dudowicz, Karl Freed, Jack F Douglas
Abstract: A Flory-Huggins type model of living polymerization is formulated, incorporating chain stiffness, variable initiator concentration and polymer-polymer interactions. Basic equilibrium properties [average chain length L, average fraction of associated ...

182. Transient Target Patterns in Phase Separating Filled Polymer Blends
Published: 9/1/1999
Authors: Alamgir Karim, Jack F Douglas, G Nisato, D W. Liu, Eric J. Amis
Abstract: Recent simulations have indicated that the presence of filler particles in a phase separating blend can induce the development of composition waves having the symmetry of the filler particles. We investigate these predictions through atomic force mi ...

183. Thermal and Mass Diffusion in a Semidilute Good Solvent-Polymer Solution
Published: 8/1/1999
Authors: K J Zhang, M E Briggs, R W Gammon, J V Sengers, Jack F Douglas
Abstract: The Soret coefficient S^dT^ and collective (mass) diffusion coefficient D^dc^ of polystyrene dissolved in the good solvent toluene is measured over a range of concentrations and molecular weights using an optical beam deflection method. Our measurem ...

184. Mean-Field-Scaling in Lattice Boltzmann Fluid Mixtures
Published: 6/1/1999
Authors: Nicos Martys, Jack F Douglas
Abstract: Basic equilibrium properties of Lattice Boltzmann (LB) fluid mixtures (coexistence curve, surface tension, and interfacial profile) are calculated to characterize the critical phenomena occurring in these model liquids and to establish a reduced vari ...

185. Dynamic Entropy as a Measure of Caging and Persistent Particle Motion in Supercooled Liquids
Published: 1/1/1999
Authors: P Allegrini, Jack F Douglas, S C Glotzer

186. Excitation of Surface Deformation Modes of a Phase Separating Polymer Blend on a Patterned Substrate
Published: 1/1/1999
Authors: G Nisato, B D Ermi, Jack F Douglas, Alamgir Karim
Abstract: The phase separation kinetics of ultrathin deuterated poly(styrene)/poly(butadiene) polymer blend films spun cast onto striped self-assembled monolayer (SAM) substrates is studied by atomic force microscopy (AFM). Fourier transform analysis of the A ...

187. Frustrated Coalescence in a Chemically Reactive Polymer Blend Film
Published: 1/1/1999
Authors: Alamgir Karim, Jack F Douglas, Sushil K Satija, Charles C. Dr. Han, R J Goyette

188. Integral Equation Approach to Condensed Matter Relaxation
Published: 1/1/1999
Author: Jack F Douglas
Abstract: A model of relaxation in supercooled and polymer liquids is developed starting from an integral equation describing relaxation in liquids near thermal equilibrium and probabilistic modeling of the dynamic heterogeneity presumed to occur in these comp ...

189. Model for the Viscosity of Particle Dispersions
Published: 1/1/1999
Authors: J Bicerano, Jack F Douglas, D A Brune

190. Spinodal Dewetting of Thin Polymer Films
Published: 8/1/1998
Authors: R H Xie, Alamgir Karim, Jack F Douglas, Charles C. Dr. Han, R A Weiss
Abstract: Dewetting of polystyrene (PS) films on a silicon substrate is investigated as a function of film thickness, h. We observe the nucleation of holes in the early stage of dewetting for relatively thick films (h > 100 {Angstrom}), as observed previously, ...
