Enhancement of structural rearrangement in glassy systems under shear flow

Enhancement of structural rearrangement in glassy sys - tems under shear flow

– We extend the analysis of the mean field schematic model recently introduced [1] for the description of glass forming liquids to the case of a supercooled fluid subjected to a shear flow of rate γ. After quenching the system to a low temperature T , a slow glassy regime is observed before stationarity is achieved at the characteristic time τg. τg is of the order of the usual equilibration tim...

Adhesion under Shear Flow

The 4 integrin, 4 7, plays an important role in recruiting circulating lymphocytes to the gastrointestinal tract, where its ligand mucosal addressin cell adhesion molecule-1 (MAdCAM-1) is preferentially expressed on high endothelial venules (HEVs). Dual antagonists of 4 1 and 4 7, N-(2,6-dichlorobenzoyl)-(L)-4-(2 ,6 -bis-methoxyphenyl)phenylalanine (TR14035) and N-{N-[(3,5-dichlorobenzene)sulfo...

Structural relaxation of glassy selenium under γ irradiation

2014 The effect of 03B3-rays on the structural relaxation of glassy selenium near the glass transition has been studied by dilatometry. We show that under irradiation the evolution time scale shifts about one decade. J. Physique LETTRES 42 (1981) L-501-L-502 . Classification Physics Abstracts 61.40D 64.70E 61.80E 15 NOVEMBRE 1981,

Bicontinuous Microemulsions under Steady Shear Flow

Dynamic response of microemulsions to shear deformation on the basis of twoorder-parameter time dependent Ginzburg-Landau model is investigated by means of cell dynamical system approach. Time evolution of anisotropic factor and excess shear stress under steady shear flow is studied by changing shear rate and total amount of surfactant. As the surfactant concentration is increased, overshoot pe...
