The desalting/salting pathway: a route to form metastable aggre-gates with tuneable morphologies and lifetimes
Sumit Mehan, Laure Herrmann, Jean-Paul Chapel +3
We investigate the formation/re-dissociation mechanisms of hybrid complexes made from negatively charged PAA2k coated γ-Fe2O3 nanoparticles (NP) and positively charged polycations…
Spatial distribution of core monomers in acrylamide-based core-shell microgels with linear swelling behaviour
Marian Cors, Oliver Wrede, Lars Wiehemeier +4
The peculiar linear temperature-dependent swelling of core-shell microgels has been conjectured to be linked to the core-shell architecture combining materials of different transit…
Structure of Surfaces and Interfaces of Poly( N,N -dimethylacrylamide) Hydrogels
Guillaume Sudre, Dominique Hourdet, Fabrice Cousin +2
We investigated the surface structure of hydrogels of poly(N,N-dimethylacrylamide) (PDMA) hydrogels synthesized and cross-linked simultaneously by redox free radical polymerization…
Switching Reversibly between Ultrastable and Unstable Foams
Anne-Laure Fameau, Arnaud Saint-Jalmes, Fabrice Cousin +7
Ultrastable foams with an optimal foamability have been obtained using hydroxyl fatty acids tubes. The stabilization results from the adsorption of monomers at the air-water interf…
Adsorption of MultiLamellar tubes with a temperature tunable diameter at the air-water interface: a process driven by the bulk properties
François Boué, Anne-Laure Fameau, Jean-Paul Douliez +3
The behavior at the air/water interface of multilamellar tubes made of the ethanolamine salt of the 12-hydroxy stearic acid as a function of the temperature has been investigated u…
Finite size and inner structure controlled by electrostatic screening in globular complexes of proteins and polyelectrolytes
Jérémie Gummel, François Boué, Daniel Clemens +1
We present an extended structural study of globular complexes made by mixing a positively charge protein (lysozyme) and a negatively charged polyelectrolyte (PSS). We study the inf…
Multiple Scale Reorganization of Electrostatic Complexes of PolyStyrene Sulfonate and Lysozyme
Fabrice Cousin, Jérémie Gummel, Daniel Clemens +2
We report on a SANS investigation into the potential for these structural reorganization of complexes composed of lysozyme and small PSS chains of opposite charge if the physicoche…
Structure Transition in PSS/Lysozyme Complexes: A Chain-Conformation-Driven Process, as Directly Seen by Small Angle Neutron Scattering
Jérémie Gummel, Fabrice Cousin, François Boué
Measurements of chain conformation in proteins/polyelectrolytes complexes (lysozyme and PSSNa) show that the crossover observed between an open structure -a chain network crosslink…
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…
