Noncontact dielectric friction
Article Abstract:
Dielectric fluctuations are responsible for the noncontact friction in high-sensitivity scanning probe microscopy of dielectric materials. The differences in measured friction among the polymers are described by relating electric field fluctuations at the cantilever tip to dielectric relaxation of the polymer.

Generalization of the friction theory for viscosity modeling
Article Abstract:
An important step forward for the friction theory (FT) is presented as the approach is extended to virtually all types of equation of state (EoS). This extension is achieved by the introduction of a rational method for splitting a given EoS into separated predominantly repulsive and attractive terms.

Ion bridging effects on the electroviscosity of flexible polyelectrolytes
Article Abstract:
An experimental study is carried out to investigate the effect of added salt on the viscosity and microstructure of sodium polystyrenesulfonate solutions. It is found that the viscosity order with respect to the valence of added cations changes, depending on the polymer and salt concentrations.
