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...
On Dispersions of Discrete Memoryless Channels with Noncausal State Information at the Encoder
Dispersions of Discrete Memoryless Channels Noncausal State Information Encoder Information Theory
2012/4/18
In this paper, we study the finite blocklength limits of state-dependent discrete memoryless channels where the discrete memoryless state is known noncausally at the encoder. For the point-to-point ca...
Velocity Dispersions and Stellar Populations of the Most Compact and Massive Early-Type Galaxies at Redshift ~1
Velocity Dispersions Stellar Populations Most Compact Massive Early-Type Galaxies
2011/10/13
We present Gran-Telescopio-Canarias/OSIRIS optical spectra of 4 of the most compact and massive early-type galaxies in the Groth Strip Survey at redshift z~1, with effective radii Reff=0.5-2.4 kpc and...
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...
Nonmonotonic Evolution of the Blocking Temperature in Dispersions of Superparamagnetic Nanoparticles
Nonmonotonic Evolution of Blocking Temperature Superparamagnetic Nanoparticles
2010/11/22
We use a Monte Carlo approach to simulate the influence of the dipolar interaction on assemblies of monodisperse superparamagnetic γ-Fe2O3 nanoparticles. We have identified a critical concentration c*...
Localized in-situ polymerization on graphene surfaces for stabilized graphene dispersions
Localized in-situ polymerization graphene surfaces stabilized graphene dispersions
2010/11/18
We demonstrate a novel in situ polymerization technique to develop localized polymer coatings on the surface of dispersed pristine graphene sheets. Graphene sheets show great promise as strong, conduc...
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...

Rheology of Polyaniline Dispersions in Acrylic Resin
Rheology of Polyaniline Dispersions Acrylic Resin
2010/4/19
Acrylic dispersions based on polyaniline were obtained and characterised. The polyaniline was obtained by chemical polymerisation of aniline in different organic acid containing phosphorous, in the pr...
