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

Qi L., Sehgal A., Castaing J.-C., Fresnais J., Berret J.-F., Chapel J.-P., 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. [...]

Synthesis of Dextran-Coated Nanoceria with pH-dependent Antioxidant Properties

Perez J.M., Asati A., Nath S., Kaittanis C., University of Central Florida, US

Cerium oxide nanoparticles (nanoceria) are potent free radical scavengers with neuroprotective, radioprotective, and anti-inflammatory properties. However, most synthetic procedures for nanoceria results in nanoparticles with poor water solubility or synthesized by procedures involving toxic solvents, [...]

8nm cerium oxide as a fuel additive for fuel consumption and emissions reduction

Wakefield G., Gardener M., Oxonica Materials Ltd, UK

8nm cerium oxide is surface functionalised for diesel compatibility and added to fuel at a level of 5-8ppm. Static engine tests and large scale field trials show that engine fuel consumption is reduced by 5-8% [...]
