Highly Stable and Oppositely Charged Hybrid Nanoparticles/Tubes. Fine Tuning of Electro-steric interactions To Fabricate Functional Surfaces

Berret J.-F., Chapel J.-P., Feltrin E., Giermanska J., Sekar S., Centre de Recherche Paul Pascal, FR

Hybrid Functional Surfaces were generated via the novel surface functionalization pathway named Surface Grown Layers (SgL),where the hybrid layers are generated in a single step at a fluid/solid interface via fine tuning of electrostatic complexation [...]

Redispersible hybrid nanopowders: cerium oxide nanoparticle complexes with phosphonated-peg oligomers

Berret J.-F., Castaing J.-C., Chapel J.-P., Fresnais J., Qi L., Sehgal A., Rhodia/CNRS joint Institution, US

Rare earth cerium oxide (ceria) nanoparticles are stabilized using end-functional phosphonated-PEG oligomers. The complexation process and structure of the resulting hybrid core-shell singlet nanocolloids are described, characterized and modeled using light and neutron scattering data. [...]

Organic versus Hybrid Coacervate Complexes: Co-Assembly and Adsorption Properties

Berret J.-F., Castaing J.-C., Chapel J.-P., Fresnais J., Qi L., Laboratoire Matière et Systèmes Complexes, FR

We report the co-assembly and adsorption properties of coacervate complexes made from polyelectrolyte-neutral block copolymers and oppositely charged nanocolloids.
