ABSTRACTSelf-assembled monolayers (SAMs) of decanoic acids were prepared on cerium oxide nanoparticles (NPs). The dispersion of the NPs was improved by increasing the packing density of decanoic acid SAM on the NPs. Highly concentrated ceria nanofluids more than 22 vol% (about 77 wt%) in cyclohexane and trans-decalin were achieved, according to the criterion to the packing density and chain length of the alkanoic acid of the SAM to disperse the ceria NPs in nonpolar organic solvents proposed previously. Temperature effect on the dispersion was also examined and it was turned out that the dispersion was strongly enhanced with activation of Brownian motion.

<p>We present a reliable method for the fabrication of fluid phase unsaturated bilayers which are readily self-assembled on charged self-assembled monolayer (SAM) surfaces producing high coverage floating supported bilayers where the membrane to surface distance could be controlled with nanometer precision. Vesicle fusion was used to deposit the bilayers onto anionic SAM coated surfaces. Upon assembly the bilayer to SAM solution interlayer thickness was 7-10 Å with evidence suggesting that this layer was present due to SAM hydration repulsion of the bilayer from the surface. This distance could be increased using low concentrations of salts which caused the interlayer thickness to enlarge to ~33 Å. Reducing the salt concentration resulted in a return to a shorter bilayer to surface distance. These accessible and controllable membrane models are well suited to a range of potential applications in biophysical studies, bio-sensors and Nano-technology.</p><br>
