Rheology of concentrated carbon nanotube suspensions.
The rheological properties of non-Brownian carbon nanotube suspensions are measured over a range of nanotube volume fractions spanning the transition from semidilute to concentrated. The polymer-stabilized nanotubes are "sticky" and form a quiescent elastic network with a well-defined shear modulus and yield stress that both depend strongly on nanotube volume fraction with different but related...
متن کاملControl of stability/flocculation and rheology of concentrated suspensions
The various interaction forces that govern the stability/flocculation of concentrated suspensions are briefly described. Combination of these interactions result in three main energy-distance curves which determine the final state of the suspension. This ranges from colloidally stable to strongly flocculated (coagulated) suspensions. A schematic representation of the various states of suspensio...
متن کاملNonequilibrium structure and rheology of concentrated colloidal suspensions: Linear response
We propose a simple theory for the pair distribution function of a sheared colloidal suspension. The starting point is an exact equation for the stationary state pair distribution. We assume that in a shear flow the higher order distributions can be expressed through the pair distribution in the same way as in an equilibrium state. To get explicit results we use a simple decoupling approximatio...
متن کاملFractal approach to the rheology of concentrated cell suspensions.
Results on the rheological behavior of Chinese hamster ovary cell suspensions in a large range of concentrations are reported. The concentration-dependent yield stress and elastic plateau modulus are formalized in the context of fractal aggregates under shear, and quite different exponents are found as compared to the case of red blood cell suspensions. This is explained in terms of intrinsic m...
متن کاملRheology of concentrated biomass
Economic processing of lignocellulosic biomass requires handling the biomass at high solids concentration. This creates challenges because concentrated biomass behaves as a Bingham-like material with large yield stresses. Here we employ torque rheometry to measure the rheological properties of concentrated lignocellulosic biomass (corn stover). Yield stresses obtained using torque rheometry agr...
