A dispersion of CeO 2 nanoparticles and nanorods stabilized with nitrilotriacetic acid (NTA) and a 4,4 0azobis(4-cyanovaleric acid) (V-501) initiator has been used to initiate the emulsion polymerization of acrylic monomers, yielding stable hybrid CeO 2 nanoparticle-nanorod/polyacrylate latexes for the first time. Films cast from these hybrid latexes are transparent due to the very homogenous distribution of the polymer compatibilized CeO 2 . Furthermore, it has been proven that the UV-Vis absorption capacity of the hybrid latexes is enhanced with the incorporation of the nanorods. † Electronic supplementary information (ESI) available: Data on the particle size distribution of CeO 2 nanoparticles and nanorods, 13 C-NMR and XPS data assignments, particle size distribution of the polymer particles, stability tests and DSC and TGA measurements.

An extremely stable water dispersion of cerium oxide nanoparticles was prepared by colloidal synthesis, using nitrilotriacetic acid (NTA) as a stabilizer.

The combined action of load and shear results in the formation of a temporary sub-micrometer hill in front of the tip. As the tip pushes against such hills, a pronounced stick-slip effect is observed for the hydrogel with low cross-linking density.
