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…
Experimental investigation of water distribution in two-phase zone during gravity-dominated evaporation
C. Cejas, J. -C. Castaing, L. A. Hough +2
We characterize the water repartition within the partially saturated (two-phase) zone (PSZ) during evaporation out of mixed wettable porous media by controlling the wettability of…
A Simple Analytical Model of Evaporation in the Presence of Roots
Cesare M. Cejas, Larry Hough, Jean-Christophe Castaing +2
Root systems can influence the dynamics of evapotranspiration of water out of a porous medium. The coupling of evapotranspiration remains a key aspect affecting overall root behavi…
Spatially heterogeneous dynamics in a thermosensitive soft suspension before and after the glass transition
Rémy Colin, Ahmed M. Alsayed, Jean-Christophe Castaing +3
The microscopic dynamics and aging of a soft thermosensitive suspension was investigated by looking at the thermal fluctuations of tracers in the suspension. Below and above the gl…
Universal scattering behavior of co-assembled nanoparticle-polymer clusters
J. Fresnais, J. -F. Berret, L. Qi +7
Water-soluble clusters made from 7 nm inorganic nanoparticles have been investigated by small-angle neutron scattering. The internal structure factor of the clusters was derived an…
Redispersible Hybrid Nanopowders: Cerium Oxide Nanoparticle Complexes with Phosphonated-PEG Oligomers
L. Qi, A. Sehgal, J. -C. Castaing +4
Rare earth cerium oxide (ceria) nanoparticles are stabilized using end-functional phosphonated-PEG oligomers. The complexation process and structure of the resulting hybrid core-sh…
