Impact of Colloidal Stability on Cellulose Nanocrystals Self-Ordering in Thin Films

Bruel C., Tavares J.R., Carreau P.J., Heuzey M.-C., polytechnique montreal, CA

Sulfuric acid hydrolyzed cellulose nanocrystals (CNC) display interesting self-ordering properties in water. Applications include water casting of optically active CNC- based materials and composites. N,N-dimethylformamide (DMF)-cast materials do not display as good properties. Variations in [...]

Investigation of the stabilisation mechanism of small ZnO quantum dots below 20 nm

Segets D., Marczak R., Schäfer S., Peukert W., Friedrich-Alexander-University of Erlangen-Nuremberg, DE

ZnO semiconductor quantum dots have attracted considerable attention during the past ten years due to their promising electro-optical properties. Besides fundamental research on the particle synthesis itself, especially the nanoparticles optimization regarding electronic devices or [...]

Invertible Polymers for the Stabilization of Nanoparticles

Kohut A., Voronov A., Peukert W., Friedrich-Alexander-University of Erlangen-Nuremberg, DE

A new range of amphiphilic polyesters with both hydrophilic and hydrophobic functionalities alternately distributed in the polymer backbone has been synthesized. These polyesters are soluble in aqueous and organic media, where they reveal inverse behavior [...]
