Scission of flexible polymers in contraction flow: predicting the effects of multiple passages
Sandeep Garrepally, Stephane Jouenne, Peter D. Olmsted +1
When injected through a contraction, high molecular weight polymer solutions exhibit a sharp increase of apparent viscosity which originates from stretching polymer chains above a…
Universal Force Correlations in an RNA-DNA Unzipping Experiment
Kay Joerg Wiese, Mathilde Bercy, Lena Melkonyan +1
We study unzipping of a complementary RNA-DNA helix applied to an external force, focusing on the force-force correlations. While at the microscopic level these are given by the se…
Probing the adsorption/desorption of amphiphilic polymers at the air-water interface during large interfacial deformations
C. Trégouët, Thomas Salez, N. Pantoustier +3
Hydrophobically modified polymers are good candidates for the stabilization of liquid interfaces thanks to the high anchoring energy of the hydrophobic parts. In this article we pr…
Adhesive contact of model randomly rough rubber surfaces
Vito Acito, Michele Ciavarella, Alexis M Prevost +1
We study experimentally and theoretically the equilibrium adhesive contact between a smooth glass lens and a rough rubber surface textured with spherical microasperities with contr…
Preferential Root Tropism Induced by Structural Inhomogeneities in 2D Wet Granular Media
Cesare M. Cejas, Lawrence A. Hough, Raphaël Beaufret +3
We investigate certain aspects of the physical mechanisms of root growth in a granular medium and how these roots adapt to changes in water distribution induced by the presence of…
