Synthesis of Gluathione-Protected Gold Nanoparticles using Diglyme
Background of the Invention:Monolayer protected thioloated gold nanoclusters are stable metal nanoparticles that are passivated by a layer of organic material. Most known syntheses of these gold nanoclusters result in products that have noble-gas-like superatomic electron configuration, such as Au25(SR)18- and Au102(SR)44. The gold nanoclusters that...

Magnetically Responsive Filtration Membranes for Reduced Fouling
By grafting short polymer chains to standard membrane filters, "nanohairs" are fabricated that can be made to move back and forth in an oscillating magnetic field. This induces very localized stirring at the membrane surface, which decreases membrane fouling and improves membrane performance and lifetime without any added chemicals or modifications...
