We report experimental results of the electrorheological (ER) and dielectric characteristics of an ER fluid made of suspensions of semiconductive polymer (polyaniline) particles in silicone oil. We found that the shear stress of this ER fluid at different applied electric fields can be scaled...

The jamming phenomenon of granular flow of mono-disperse disks in a two-dimensional hopper is studied experimentally. When the opening of the hopper d is small, jamming occurs due to formation of an arch at the hopper opening. The jamming probability as a function of the hopper opening width is...

The phase equilibrium behavior of a dilute high molecular weight polymer (poly-ethylene oxide PEO, molecular weight 9 × 105, concentration 0.001 g/cc) solution in a two-component liquid mixture (isobutyric acid + water, IBAW) is studied experimentally. Far above the critical temperature Tc of...
