The subject of this paper is the evolution of Brownian particles in disordered environments.
The “Ariadne's clew” we follow is understanding of the general statistical mechanisms which …

This review covers the recent advances in studies of the volume phase transition and critical
phenomena of polymer gels mostly carried out in our group from 1973 to the present. We …

Vesicles consisting of a bilayer membrane of amphiphilic lipid molecules are remarkably
flexible surfaces that show an amazing variety of shapes of different symmetry and topology …

We discuss shear flows of a polymer melt near a solid surface onto which a few chains
(chemically identical to the melt) have been grafted. At low shear rates<* we expect a strong …

Highly branched “bottlebrush” polymers are a class of macromolecules characterized by
side chains that are densely grafted from a backbone that is typically linear. Their unique …

A great variety of models can describe the nonlinear response of rubber to uniaxial tension.
Yet an in-depth understanding of the successive stages of large extension is still lacking. We …

The forces between polymer-bearing surfaces in motion with respect to each other in a liquid
medium are very different from their equilibrium interactions and control effects ranging from …

Single polymer dynamics offers a powerful approach to study molecular-level interactions
and dynamic microstructure in materials. Direct visualization of single polymer chains has …

Turbulent drag reduction by polymer additives in a channel is investigated using direct
numerical simulation. The dilute polymer solution is expressed with an Oldroyd-B model that …

ADSORBED or grafted polymers are used to control phenomena such as colloidal stability,
fluid flow and the tribological properties of surfaces. Forces between polymer-bearing …
