Localization and Number of Au Nanoparticles in Optically Indexed Cells by FIB Tomography

August 2, 2015
Author(s)
Aric W. Sanders, Kavita M. Jeerage, Ann C. Chiaramonti Debay, Alexandra Curtin
Gold nanoparticles (GNPs) are gaining importance as therapeutic chemical delivery vehicles, medical diagnostic tools, phototherapeutic and contrast enhancement agents. GNPs are uniquely suited for these biological uses because of their chemical stability

ADAPTING OECD AQUATIC TOXICITY TESTS FOR USE WITH MANUFACTURED NANOMATERIALS: KEY ISSUES, CONSENSUS RECOMMENDATIONS, AND DATA GAPS

July 16, 2015
Author(s)
Elijah J. Petersen, Alan Kennedy, Greg Goss, Ho Kay, Jamie Lead, Shannon Hanna, Kerstin Hund-Rinke, Brian Mader, Nicholas Manier, Pascal Pandard, Edward Salinas, Kathrin Schwirn, Doris Voelker
The unique or enhanced properties of manufactured nanomaterials (MNs) suggest that their use in nano-enabled products will continue to increase in the future. This will result in increasing potential for human and environmental exposure to MNs, during

Utilizing Nearest-Neighbor Interactions to Alter Charge Transport Mechanisms in Molecular Assemblies of Porphyrins on Surfaces

May 27, 2015
Author(s)
James G. Kushmerick, Amanda E. Schuckman, Lisa M. Perez, Mikki Vinodu, Joao Tome, Lam H. Yu, Charles M. Drain, James D. Batteas
When tunneling is the dominant mechanism of charge transport in a molecular junction, the conductivity of the junction is largely insensitive to chemical and structural perturbations which do not impact the overall length of the junction. This severely

Thermal Analysis of Nanoparticles: Methods, Kinetics and Recent Advances

May 4, 2015
Author(s)
Elisabeth Mansfield
This chapter will provide an overview of the thermal techniques available to study nanoparticles, including thermogravimetric analysis, calorimetry and differential scanning calorimetry. The use of thermoanalysis for the measurement of nanoparticle purity

Terbium-Doped Magnetite Nanocrystals for Multimodal Imaging Agents

May 1, 2015
Author(s)
Katherine P. Rice, Stephen E. Russek, Roy H. Geiss, Justin M. Shaw, Robert J. Usselman, Eric R. Evarts, Thomas J. Silva, Hans T. 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 room

Elemental characterization of Single-Wall Carbon Nanotube (SWCNT-1) reference material by neutron and prompt gamma activation analysis

April 7, 2015
Author(s)
Rick L. Paul, Rabia Oflaz, Jan Kucera, J W Bennett, E. A. De Nadai Fernandes, M. Kubesova, M. A. Bacchi, A. J. Stopic, R. E. Sturgeon, P. Grinberg
Instrumental neutron activation analysis with both relative and k0 standardization was used in four experienced laboratories to determine element mass fractions in single-wall carbon nanotube certified reference material (CRM) SWCNT-1. Results obtained

Interactions of Microorganisms with Polymer Nanocomposites Containing Different Loadings of Oxidized Single and Multi-walled Carbon Nanotubes

March 27, 2015
Author(s)
David G. Goodwin , Kris M. Marsh, Iruhany B. Sosa, Julianne B. Payne, Justin Gorham, Edward J. Bouwer, D H. Fairbrother
The environmental fate and impact of polymer nanocomposites (PNCs) containing carbon nanotubes (CNTs) will depend upon their interactions with microorganisms, with implications for the antimicrobial properties and long term persistence of PNCs. Using
