Effect of Solutes on the Viscosity of Supercritical Solutions
The Journal of Physical Chemistry B, 2007This study shows that solutes can impart significant structure to supercritical solutions, resulting in unexpectedly high solution viscosity at pressures close to the critical value. The viscosity passes through a minimum as the pressure is increased, and this is accounted for by a solvation of the solutes leading to a decrease in solute-solute ...

The viscosity of short polyelectrolyte solutions
Soft Matter, 2014We consider the viscosity of solutions of highly charged short polyelectrolytes. Our system is a poly(styrene-maleic acid) copolymer solution (SMA) with various added salt concentrations in dilute and semidilute regimes. The SMA solutions show some particular features: (i) variations of the specific viscosity measured for different values of ...

Viscosity Solutions of Minimization Problems
SIAM Journal on Optimization, 1996Viscosity methods provide an efficient approach to a large number of problems coming from different branches of mathematical analysis, such as mathematical programming (for example, Tikhonov regularization and exponential penalty methods for linear programming), variational problems (for example, minimal hypersurfaces, plasticity theory, and phase ...

Viscosity of Polyelectrolytes Solutions in Nanofilms
Langmuir, 2010We use a thin film pressure balance to probe the rheological properties of thin liquid films. These films are made from mixed aqueous solutions of surfactants and polyelectrolytes. They drain under applied pressure in a noncontinuous way due to a stratification process of the polyelectrolytes network.

Viscosity of alpha-crystallin solutions
International Journal of Biological Macromolecules, 2002Accommodation in the mammalian lens requires flexure of lens fibres and some redistribution of their contents involving limited viscous flow. Shear-dependent viscosity of bovine alpha-crystallin solutions was determined with the Contraves Low-Shear Rheometer between 4.4 and 347 mg ml(-1), and at 15.5, 25, 30, and 37 degrees C.

The viscosity of macroglobulin and euglobulin solutions
Clinica Chimica Acta, 1959Abstract The viscosity of solutions of seven euglobulins has been determined at different concentrations; five of these are correlated with ultracentrifuge measurements. The effect of pH on the viscosity of globulin solutions has been determined. Treatment of a macroglobulin solution with mercaptoethanol lowered its viscosity.

On the Influence of Viscosity on Riemann Solutions
Journal of Dynamics and Differential Equations, 1998This paper is a study of traveling waves for \(2\times 2\) systems of conservation laws that change type, with added viscous terms. Using the framework of the fundamental wave manifold, the author systematically analyzes vector fields whose separatrices represent traveling waves.

The viscosity of dilute solutions
Journal of the Society of Chemical Industry, 1946AbstractDilute solutions of many simple binary mixtures conform to the viscosity relationship:— ηs=η0(1+kθ) Where η5 η0 are the viscosities of solution and solvent respectively, θ is the concentration and k is a constant. The constant k has an approximately linear relationship to the molecular weights of the solutes but varies for different homologous ...
