Rheology of Soft Glassy Materials
We attribute similarities in the rheology of many soft materials (foams, emulsions, slurries, etc.) to the shared features of structural disorder and metastability. A generic model for the mesoscopic… Expand

The flow anisotropy of a concentrated colloidal suspension at the jamming transition is studied. It is shown that the use of rough spherical particles reduces the hydrodynamic lubrication forces… Expand
Giant stress fluctuations at the jamming transition.
We study the stress response to a steady imposed shear rate in a concentrated suspension of colloidal particles. We show that, in a small range of concentrations and shear rates, stress exhibits… Expand

alpha-Cyclodextrins (alpha-CDs) have the ability to form inclusion complexes with poly(ethylene oxide) (PEO) polymer chains. These pseudo-polyrotaxanes (PPRs) can be obtained by quenching an… Expand
Rheology of Emulsions Stabilized by Solid Interfaces
The rheological behavior of soybean oil emulsions stabilized by sodium caseinate is studied. While having a very low interfacial tension, these emulsions, when concentrated up to an oil volume… Expand
Viscoelastic Properties of Poly(vinyl alcohol) Hydrogels Having Permanent and Transient Cross-Links Studied by Microrheology, Classical Rheometry, and Dynamic Light Scattering
Dynamics of poly(vinyl alcohol) (PVA) hydrogels having chemical and physical transient cross-links simultaneously (dual cross-link PVA gels) were studied by microrheology based on diffusing-wave… Expand
Gelation, Shear-Thinning and Shear-Thickening in Cement Slurries
Gelation, Shear-Thinning and Shear-Thickening in Cement Slurries — The rheological behavior of cement slurries may be described in terms of a few elementary behaviors: - the rapid formation of a gel,… Expand
Role of Permeation in the Linear Viscoelastic Response of Concentrated Emulsions
We have studied the viscoelastic reponse of a concentrated emulsion. We have detected a slow relaxation in uniaxal flow that does not exist in simple shear flow. We demonstrate that the relaxation… Expand
Scaling laws for the flow of generalized Newtonian suspensions
It has been observed that flow curves (viscosity vs shear rate) of spherical solid inclusions suspended in a generalized Newtonian fluid medium can be rescaled so as to collapse onto the flow curve… Expand
A ruthenium-containing organometallic compound reduces tumor growth through induction of the endoplasmic reticulum stress gene CHOP.
Cisplatin-derived anticancer therapy has been used for three decades despite its side effects. Other types of organometallic complexes, namely, some ruthenium-derived compounds (RDC), which would… Expand
