Pretreatment with Pyridoxamine Mitigates Isolevuglandinassociated Retinal Effects in Mice Exposed to Bright Light

October 11, 2013
Author(s)
Casey Charvet, Aicha Saadane, Meiyao M. Wang, Robert Salomon, Henri Brunengraber, Christine Curcio, Illarion Turko, Irina Pikuleva
The benefits of antioxidant therapy for treating age-related macular degeneration, a devastating retinal disease, are limited. Perhaps species other than reactive oxygen intermediates should be considered as therapeutic targets. These could be lipid

99.996% 12C films enriched and deposited in situ

June 28, 2013
Author(s)
Kevin J. Dwyer, Joshua M. Pomeroy, David S. Simons
A mass selected ion beam system is used to isotopically enrich and deposit thin films, which are measured to be 99.9961(4)% 12C. In solid state quantum information, isotopic enrichment of materials has allowed significant improvements in the coherence time

Surface Chemical Transformations of UV irradiated Silica-Epoxy Nanocomposites

May 15, 2013
Author(s)
Justin M. Gorham, Tinh Nguyen, Deborah S. Jacobs, Coralie Bernard, Richard D. Holbrook
Silica nanoparticles (SiNPs) incorporated into a polymeric matrix, or silica nanocomposites (SiNCs), are used in a wide variety of commercially available products in numerous natural and artificial environments. Environmental factors, such as light, may

Characterization of Stabilized Zero Valent Iron Nanoparticles

December 10, 2011
Author(s)
Lauren F. Greenlee, Stephanie A. Hooker
The demonstrated toxicity of certain groups of organic micropollutants in water sources has motivated research in developing novel materials that are able to remove dissolved organic molecules from an aqueous system through adsorption and/or degradation

Magnetic Tunnel Junctions Fabricated Using Ion Neutralization Energy as a Tool

July 25, 2011
Author(s)
Joshua M. Pomeroy, Holger Grube, Pei-Ling Sun, Yun-Che Wang, Russell E. Lake
The neutralization energy of highly charged ions (HCIs) is used as an intermediate processing step to modify the electrical properties of magnetic tunnel junctions (MTJs), providing an additional degree of freedom in the devices’ fabrication. While most

Infrared Emittance Measurements at NIST

October 5, 2005
Author(s)
Leonard M. Hanssen, Benjamin K. Tsai, Sergey Mekhontsev
A new capability for the measurement of the temperature-dependent emittance of specular samples in the near infrared spectral region has been developed in NIST s Infrared Spectrophotometry Laboratory to provide emittance measurements and standards for a

Nanometer Resolution Metrology with the NIST Molecular Measuring Machine

September 23, 2005
Author(s)
John A. Kramar
Nanometre accuracy and resolution metrology over technically relevant areas is becoming a necessity for the progress of nanomanufacturing. At the National Institute of Standards and Technology, we are developing the Molecular Measuring Machine, a scanned

Origin of Exchange Decoupling Effects in High-Coercivity Air-Annealed CoPd Multilayers

May 1, 2005
Author(s)
William F. Egelhoff Jr., Robert McMichael, J Mallett, Alexander J. Shapiro, Cedric J. Powell, John E. Bonevich, J H. Judy, J H. Thomas, Erik B. Svedberg
We have achieved excellent exchange decoupling of grains in CoPd multilayers by annealing in air at 300 C. Samples exhibit a slope in the hysteresis loop close to 1.0, nucleation fields as large as 1.1 T, and coercivities as large as 1.6 T. These are among

Structure and Chemical Characterization of Self-Assembled Mono-Fluoro-Substituted Oligo(phenylene-ethynlyene) Monolayers on Gold

June 22, 2004
Author(s)
Christina Hacker, James D. Batteas, J C. Garno, Manuel Marquez, Curt A. Richter, Lee J. Richter, Roger D. van Zee, Christopher D. Zangmeister
Monolayers of oligo(phenylene-ethynylene) (OPE) molecules have exhibited promise in molecular electronic test structures. This paper discusses films formed from novel molecules within this class, 2-fluoro-4-phenylethynyl-1-[(4-acetylthio)-phenylethynyl

Combined NMR and XAS Study on Local Environments and Electronic Structures of the Electrochemically Li-Ion Deintercalated Li1-xCo1/3Ni1/3Mn1/302 Electrode System

January 1, 2004
Author(s)
W S. Yoon, C P. Grey, Mahalingam Balasubramanian, Xiao-Qing Yang, Daniel A. Fischer, James McBreen
Combined 6Li MAS NMR, in-situ metal K-edge (hard) XAS, and O K-edge (soft) XAS have been carried out during the first charging process for the layered Li1-xCo1/3Ni1/3Mn1/3O2 cathode material. The 6Li MAS NMR results showed the prescence of Li in the Ni2+
