21. Photo-induced Surface Transformation of Silica Nanocomposites
Topic: Nanotech/Environment, Health & Safety
Published: 6/22/2012
Authors: Justin M Gorham, Tinh Nguyen, Coralie Bernard, Deborah L Stanley, Richard D Holbrook
Abstract: The physicochemical, UV-induced surface modifications to silica nanoparticle (SiNP) - epoxy composites have been investigated. The silica nanocomposites (SiNCs) were prepared using a two-part epoxy system with 10 % mass fraction of SiNPs and expose ...

23. CEINT/NIST PROTOCOL for the PREPARATION OF NANOSCALE TiO2 DISPERSIONS IN AN ENVIRONMENTAL MATRIX FOR ECO-TOXICOLOGICAL ASSESSMENT
Topic: Nanotech/Environment, Health & Safety
Published: 2/2/2012
Authors: Julian S. Taurozzi, Vincent A Hackley, Mark R Wiesner
Abstract: Toxicity and fate assessment are key elements in the evaluation of the environmental, health and safety risks of engineered nanomaterials (ENMs). While significant effort and resources have been devoted to the toxicological evaluation of many ENMs, i ...

24. Anisotropic surface-state-mediated RKKY interaction between adatoms
Topic: Nanotech/Environment, Health & Safety
Published: 1/18/2012
Authors: Paul Nathan Patrone, T L Einstein
Abstract: Motivated by recent numerical studies of Ag on Pt(111), we derive a far-field expression for the RKKY interaction mediated by surface states on a (111) FCC surface. The main contribution to the interaction comes from electrons whose Fermi velocity ...
