New Nanoparticles Study Findings Reported from Alternative Energies and Atomic Energy Commission

June 27, 2014

By a News Reporter-Staff News Editor at Science Letter -- New research on Nanoparticles is the subject of a report. According to news originating from Bagnols sur Ceze, France, by NewsRx correspondents, research stated, "Hybrid tri(dodecyldimethylammonium) phosphotungstate ([C-12](3)[PW12O40] amphiphilic nanoparticles self-assemble in situ at the water/toluene interface to form stable water-in-oil (W/O) Pickering emulsions (droplet size approximate to 20 mu m). These emulsions are used as a template for the preparation of colloidosomes (phi approximate to 5 mu m), which are produced solely through the self-assembly properties of the [C-12](3)[PW12O40] nanoparticles into a 'fused' phase on the water-drop surface in contact with toluene."

Our news journalists obtained a quote from the research from Alternative Energies and Atomic Energy Commission, "The structure of the emulsions has been determined using optical and cross-polarized light microscopy, while the colloidosomes have been characterized by scanning electron microscopy (SEM). The structure as well as the aggregation behavior of these nanoparticles has been investigated. Small- and wide-angle X-ray scattering (SWAXS) and transmission electron microscopy (TEM) experiments have revealed a lamellar organization of the inorganic polyoxometalate anions because of the van der Waals interactions between the alkyl chains of the organic cations."

According to the news editors, the research concluded: "According to the solvent, the internal molecular arrangement inside the nanopartides can be modified: in water, the nanoparticles tend to aggregate in a lamellar structure, whereas in toluene, the nanoparticles are 'fused' or coagulated."
