Moduli of Continuity for Viscosity Solutions on Manifolds

, 2015
We establish the estimates of modulus of continuity for viscosity solutions of nonlinear evolution equations on manifolds, extending previous work of Andrews and Clutterbuck for regular solutions on manifolds (Andrews and Clutterbuck in Anal PDE 6(5 ...

The viscosity of dilute solutions

Journal of the Society of Chemical Industry, 1946
AbstractDilute 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 ...

Viscosity of Polymer Solutions

The Journal of Chemical Physics, 1963
In the expression for the viscosity of polymer solutions η=η0+[η]C+K[η]2C2+···, the Huggins constant K is calculated for hard spheres and for interpenetrable spheres of uniform segment density. For hard spheres K = 0.6909, and for soft spheres where K is larger, the dependence of K on the segment—segment interaction constant is given.

Viscosity of Polyelectrolytes Solutions in Nanofilms

Langmuir, 2010
We 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 polyelectrolyte solutions

Die Makromolekulare Chemie, 1970
AbstractThe viscosity behaviour of polyelectrolytes in solutions of low ionic strength has been investigated. The dependence of the viscosity on the degree of substitution, the molecular weight and the velocity gradient was studied in detail. The measurements were carried out in solutions of different ionic strength and the limiting intrinsic viscosity

The viscosity of an oriented solution

Journal of Engineering Physics, 1970
The effects of oriented linear macromolecules are examined in relation to the viscosity of a polymer solution in simple shear and in axially symmetric extension. The effective viscosity is calculated for a solvent containing uniformly distributed rigid rods oriented along the tension axis.
