Development of a Renewable Fuel Nanotechnology

Klausmeier V., Sylvatex Inc., US

The authors have developed a technology to blend biomass-derived oxygenates - alcohols, free fatty acids, neutralizer, and water – together to form a renewable blendstock. When blended into diesel, the resulting microemulsion fuel has been [...]

Nanoparticles: Synthesis and Film Deposition Using a Simple and Fast Centrifuge Sedimentation Method

Wang J-S., Markelonis A.R., Wai C.M., Brown G.J., Air Force Research Laboratory, US

Gold nanoparticles were prepared by reduction of gold cations suspended in sodium bis(2-ethylhexyl)sulfosuccinate (AOT) water-in-hexane microemulsions with another AOT microemulsion containing a reducing agent NaCNBH3. The size of the Au nanoparticles can be controlled by [...]

Facile doping of silica nanoparticles with far-red cyanine dyes using the microemulsion method

Nooney R., McDonagh C., Biomedical Diagnostics Institute, IE

We prepared silica NPs doped with two far-red absorption cyanine dyes, FR670 and Cy5, using the microemulsion method. At these wavelengths there is less autofluorescence from biological molecules, solvents and substrates. The effects of changing [...]

Synthesis and Application of nano-size polymer colloids at The Dow Chemical Company

Tucker C.J., The Dow Chemical Company, US

Over the last 50+ years The Dow Chemical Company has sponsored numerous research programs involving the preparation and use of nano-size colloidal systems. The nano-colloids used range from soft (liquid microemulsions) to solid (polymeric) materials [...]

Synthesis, Extraction and Surface Modification Of (Zn,Mn)Se Nanocrystals Using Microemulsions As Templates

Heckler T., Qiu Q., Wang J., Mei B., Mountziaris T.J., University of Massachusetts, US

This research focuses on the novel room temperature synthesis of (Zn,Mn)Se quantum dots that exhibit luminescence peaks at longer wavelengths than the ZnSe bulk emission, due to the Mn ions incorporated in the ZnSe lattice. [...]

Calcium-Alginate Nanoparticles for Nonviral Gene Delivery

You J-O, Peng C-A, University of Southern California, US

Natural biopolymers are widely used in the filed of drug and gene delivery. In this study, alginate nanoparticles were prepared using water-in-oil microemulsion as a template followed by calcium crosslinking of guluronic acid units of [...]
