Studies of Ordered Monodisperse Latexes. III. Viscoelasticity and Flow Properties
TLDR
In this paper, the viscoelastic properties of monodisperse polystyrene latexes were measured through an order-disorder transition as varying the salt concentration in the solvent and the volume fraction of spheres.Abstract:
The viscoelastic behaviour at 40 kHz and the steady flow properties of monodisperse polystyrene latexes, i.e. aqueous suspensions of charged polystyrene spheres, were measured through an order-disorder transition as varying the salt concentration in the solvent and the volume fraction of spheres. A latex in the ordered lattice structure showed the rigidity of about 103 dyn/cm2 and the yield stress of about 1 dyn/cm2, which indicates that the ordered latex is a crystal in view of the mechanical properties. The ratio, 10-3, of the yield stress to the rigidity suggests a dislocation mechanism of the plastic flow of the ordered latex.read more

On the electrostatic interaction in macroionic solutions
Ikuo S. Sogami,Norio Ise +1 more
TL;DR: In this article, a general theory on the electrostatic interaction in macroionic solution is developed, where the motion of macroions is adiabatically cut off from that of simple ions and the distribution of simple ion is determined by the Boltzmann distribution.

Structural Ordering in Colloidal Suspensions
TL;DR: Colloids define a range of systems containing dispersed particles that are larger than atomic dimensions but small enough to exhibit Brownian motion, which prevents appreciable sedimentation in normal gravity as discussed by the authors.

Studies in Molecular Dynamics. V. High‐Density Equation of State and Entropy for Hard Disks and Spheres
TL;DR: In this article, the equations of state for periodic systems of hard disks and hard spheres in the solid phase have been accurately determined and used to evaluate the coefficients in the expansion of the pressure in powers of the relative free volume.
