Slippage and Migration in Taylor-Couette Flow of a Model for Dilute Wormlike Micellar Solutions
(2005-06-09)
In this paper we explore a model, most appropriate for dilute or semi-dilute worm-like micellar solutions, in an axisymmetric circular Taylor-Couette 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
(2005-08-26)
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 organic-inorganic polyhedral ...
Shock Dynamics in Particle-Laden Thin Films
(2005-04-22)
We present theory and experiments for thin film particle-laden flow on an incline. At higher particle concentration and inclination angle, a new phenomenon is observed in which a large particle-rich ridge forms at the ...
Miscibility and Viscoelastic Properties of Acrylic Polyhedral Oligomeric Silsesquioxane-Poly(methyl methacrylate) Blends
(2005-04-19)
We investigate the miscibility of acrylic polyhedral oligomeric silsesquioxanes (POSS)
[characteristic size d ≈ 2 nm] and poly(methyl methacrylate)(PMMA) in order to determine the
effect of well-dispersed POSS nanoparticles ...
Iterated Stretching, Extensional Rheology and Formation of Beads-on-a-String Structures in Polymer Solutions
(2005-12-01)
The transient extensional rheology and the dynamics of elastocapillary thinning in aqueous solutions of polyethylene oxide (PEO) are studied with high-speed digital video microscopy. At long times, the evolution of the ...
Nonlinear Shear and Extensional Flow Dynamics of Wormlike Surfactant Solutions
(2005-10-04)
Nonlinear shear and extensional flow dynamics of rheological properties of a wormlike
micellar solution based on erucyl bis (2-hydroxyethyl) methyl ammonium chloride, EHAC, are reported here. The influences of surfactant ...
Rheology and Dynamics of Associative Polymers in Shear and Extension: Theory and Experiment
(2005-08-22)
We investigate the steady and transient shear and extensional rheological properties of a
series of model hydrophobically modified ethoxylate-urethane (HEUR) polymers with varying degrees of hydrophobicity. A new nonlinear ...
Controlling the Location and Spatial Extent of Nanobubbles Using Hydrophobically Nanopatterned Surfaces
(2005-08-22)
The presence of nanobubbles—as imaged with tapping-mode atomic force microscopy—
is controlled using nanopatterned surfaces possessing repeating patterns of polystyrene (hydrophobic domains) and polymethyl-methacrylate ...
Iterated Stretching and Multiple Beads-on-a-String Phenomena in Dilute Solutions of Highly-Extensible Flexible Polymers
(2005-04-13)
The dynamics of elastocapillary thinning in high molecular weight polymer solutions are re-examined
using high-speed digital video microscopy. At long times, the evolution of the viscoelastic thread deviates from self-similar ...
