pH effects on shear thickening behaviors of polystyrene-ethylacrylate colloidal dispersions
shear thickening fluid critical shear rate pH zeta potential PSt-EA
2015/3/24
In this study, the effects of pH on shear thickening behaviors were investigated based on concentrated dispersions consisting of polystyrene-ethylacrylate (PSt-
EA) copolymer nanospheres. The pH valu...

Influence of surfactants on shear-thickening behavior in concentrated polymer dispersions
Shear-thickening Surfactant Styrene–ethylacrylate copolymer Viscosity
2015/3/24
Concentrated dispersions consisting of 310 nm poly(styrene–ethylacrylate) nanospheres and ethylene glycol, which exhibited pronounced shearthickening
behavior, were prepared in this work. The influen...
Interplay between a hydrodynamic instability and a phase transition: the Faraday instability in dispersions of rodlike colloids
a hydrodynamic instability a phase transition Interplay rodlike colloids
2011/9/15
Strong effects of the Faraday instability on suspensions of rodlike colloidal particles are reported through measurements of the critical acceleration and of the surface wave amplitude. We show that t...
Numerical Simulation of Oil Dispersions in Vertical Pipe Flow
Numerical simulation Computational fluid dynamics Immiscible dispersion Vertical pipe flow Interface force
2010/9/8
Immiscible liquid dispersions are widely used in chemical process, petroleum industries, polymerization, heterogeneous chemical synthesis, etc. In most of these chemical processes, the rate of inter-p...
Synthesis, Characterization and Surface Properties of Cross-linked Polyurethane Dispersions Modified by Organosiloxane
polydimethylsiloxane (PDMS) surface properties polyurethane
2009/11/13
A series of cross-linked polyether-polyester polyurethane dispersions modified with organosiloxane were prepared based on hydroxyl-terminated polydimethylsiloxane (HTPS) as hydrophobic component and 3...
Wide bandwidth, large, and tunable polarization mode dispersions in multilayered omnidirectional reflectors
Wide bandwidth tunable polarization mode dispersions multilayered omnidirectional
2015/8/11
We numerically demonstrate the generation of large, broadband, and tunable polarization mode dispersion ~PMD! with omnidirectionally reflecting dielectric stacks with embedded cavities. Both ...
