Rheology and Dynamics of Associative Polymers in Shear and Extension: Theory and Experiment
(20050822)We investigate the steady and transient shear and extensional rheological properties of a series of model hydrophobically modified ethoxylateurethane (HEUR) polymers with varying degrees of hydrophobicity. A new nonlinear ... 
Shock Dynamics in ParticleLaden Thin Films
(20050422)We present theory and experiments for thin film particleladen flow on an incline. At higher particle concentration and inclination angle, a new phenomenon is observed in which a large particlerich ridge forms at the ... 
Slippage and Migration in TaylorCouette Flow of a Model for Dilute Wormlike Micellar Solutions
(20050609)In this paper we explore a model, most appropriate for dilute or semidilute wormlike micellar solutions, in an axisymmetric circular TaylorCouette geometry. This study is a natural continuation of earlier work on ... 
Thermorheological Properties Near the Glass Transition of Oligomeric Poly(methyl methacrylate) Blended with Acrylic Polyhedral Oligomeric Silsesquioxane Nanocages
(20050826)Two distinct oligomeric species of similar mass and chemical functionality (Mw ≈ 2,000 g/mol), one a linear methyl methacrylate oligomer (radius of gyration Rg ≈ 1.1 nm) and the other a hybrid organicinorganic polyhedral ... 
Tuning Gastropod Locomotion: Modeling The Influence Of Mucus Rheology on the Cost of Crawling
(20070504)Common gastropods such as snails crawl on a solid substrate by propagating muscular waves of shear stress on a viscoelastic mucus. Producing the mucus accounts for the largest component in the gastropod’s energy budget, ... 
TwoDimensional SelfAssembly in Diblock Copolymers
(20050620)Diblock copolymers confined to a twodimensional surface may produce uniform features of macromolecular dimensions (10 âˆ’ 100 nm). We present a mathematical model for nanoscale pattern formation in such polymers which ... 
ViscoElastoCapillary Thinning and BreakUp of Complex Fluids
(20050609)The progressive breakup of an initially stable fluid column or thread into a number of smaller droplets is an important dynamical process that impacts many commercial operations from spraying and atomization of fertilizers ...
