381. Nanoparticle Release from Polymer Nanocomposites Used for Potable Water Infrastructure and Food Packaging: Current Progress & Beyond
Andrew Whelton, T.V. Duncan , J.L. Koontz , Tinh Nguyen
Nanoparticle (NP) enhanced polymers have the potential to revolutionize food packaging and water pipe performance, though release from these materials has gone relatively unstudied. A literature review was conducted to identify potential NP release p ...
382. Terbium-Doped Magnetite Nanocrystals for Multimodal Imaging Agents
Katherine P Rice, Stephen E Russek, Roy Howard Geiss, Justin M Shaw, Robert John Usselman, Eric R Evarts, Thomas J Silva, Hans Toya Nembach, Elke Arenholz, Yves Idzerda
High quality cubic Tb-doped magnetite nanocrystals have been fabricated and have shown that the Tb is
incorporated into the octahedral 3+ sites. Magnetization and FMR data indicate that the Tb spins are
weakly coupled to the iron spin lattice at ...
383. Competitive Adsorption of Thiolated Polyethylene Glycol and Mercaptoproprionic acid on Gold Nanoparticles Measured by Physical Characterization Methods
De-Hao D. Tsai, Frank W DelRio, Robert I. MacCuspie, Tae Joon Cho, Michael Russel Zachariah, Vincent A Hackley
Adsorption kinetics between thiolated polyethylene glycol (SH-PEG) and mercaptoproprionic acid (MPA) on gold nanoparticles (Au-NP) were studied using dynamic light scattering (DLS) and electrospray differential mobility analysis (ES-DMA). Through a c ...
