Generality of shear thickening in suspensions [PDF]
, 2010 Suspensions are of wide interest and form the basis for many smart fluids. For most suspensions, the viscosity decreases with increasing shear rate, i.e. they shear thin. Few are reported to do the opposite, i.e.

Synthesis of TiO2/Pd and TiO2/PdO Hollow Spheres and Their Visible Light Photocatalytic Activity
International Journal of Photoenergy, Volume 2020, Issue 1, 2020., 2020 A series of TiO2, TiO2/Pd, and TiO2/PdO hollow sphere photocatalysts was successfully prepared via a combination of hydrothermal, sol‐immobilization, and calcination methods. The structure and optical properties of the as‐prepared samples were characterized by X‐ray diffraction, field emission scanning electron microscopy, transmission electron ...

An electro-rheological study of the nematic liquid crystal 4-n-heptyl-4'-cyanobiphenyl [PDF]
, 2010 An experimental and theoretical study of the electro-rheological effects observed in the nematic phase of 4-n-heptyl-4'-cyanobiphenyl has been conducted. This liquid crystal appears to be a model system, in which the observed rheological behaviour can be

Electrorheological Properties of Suspensions of Polypyrrole- Coated Titanate Nanorods
Applied Rheology, 2011 The behaviour of silicone-oil suspensions of titanate nanorods coated with polypyrrole base in electric field has been investigated. Unlike suspension of globular particles of neat polypyrrole, rod-like particles show a stronger electrorheological (ER ...

Electrorheological fluids [PDF]
, 1996 An Electrorheological fluid is normally a low-viscosity colloidal suspension, but when an electric field is applied, the fluid undergoes a reversible transition to a solid, being able to support considerable stress without yield. Commercial possibilities for such fluids are enormous, including clutches, brakes, valves,shock absorbers, and stepper ...

Structure of electrorheological fluids [PDF]
The Journal of Chemical Physics, 2000 Specially synthesized silica colloidal spheres with fluorescent cores were used as model electrorheological fluids to experimentally explore structure formation and evolution under conditions of no shear. Using confocal scanning laser microscopy we measured the location of each colloid in three dimensions.

Electrorheology of Non-aqueous Suspensions
KONA Powder and Particle Journal, 2014 An excellent electrorheological (ER) suspension is invented with composite particles consisting of polymer core and inorganic shell. When the composite particles are subjected to jetstream agitation, the ER effects ...

Halloysite nanotubes: Prospects in electrorheology
eXPRESS Polymer Letters, 2018 Electrorheological fluids based on polydimethylsiloxane filled with halloysite nanotubes were studied. The filler structure was characterized by TEM, SEM, and X-ray diffraction. When an electric field is applied to suspensions, their rheological behavior
