Growth of Magnetic Nanowires in an Applied Field

October 12, 2021
Author(s)
R D K. Misra, H Nathani, William F. Egelhoff Jr.
Nanostructured quasi one-dimensional magnetic materials (nanowires) have attracted significant scientific and technological interest because they exhibit unique magnetic properties not displayed by their bulk or nanoparticle counterparts. Nanocrystalline

High Sensitivity CARS Microscopy With Two Tightly SynChronized Picosecond Lasers

October 12, 2021
Author(s)
J Potman, D J. Jones, J X. Cheng, X. Xie, Jun Ye
We demonstrate a significant improvement in signal-to-noise ratio recovered from coherent anti-Stokes Raman scattering (CARS) spectroscopy/microscopy, using two tightly synchronized picosecond Ti: sapphire lasers. A temporal jitter between the pulse trains

High-Resolution Ultrasonic Thermometer for Radiation Dosimetry

October 12, 2021
Author(s)
Eugene Malyarenko, Joseph Heyman, Heather H. Chen-Mayer, Ronald Tosh
This paper describes recent developments in the area of high-precision This paper describes recent developments in the area of high-precision ultrasonic thermometry with the potential to provide on-site direct determination of radiation dose and its

Highly Phase Stable Modelocked Lasers

October 12, 2021
Author(s)
T M. Fortier, D J. Jones, Jun Ye, Steven T. Cundiff
We report on stabilizing the carrier-envelope phase of modelocked Ti:sapphire lasers. Optimization of the construction of the lasers for ease of phase stabilization is discussed. Results demonstrating long term phase coherence of the generated pulse train

Homological Metrics for Microstructure Response Fields in Polycrystals

October 12, 2021
Author(s)
Lin-Sien H. Lum, D M. Saylor, Thomas Wanner
Quantitative homological metrics are proposed for characterizing the thermal-elastic response of calcite-based polycrystals. The characterization is based on topological measurements, such as the number of components and the number of handles of a complex

Human Mitochondrial Protein Database: A Resource for Human Mitochondrial Proteomics

October 12, 2021
Author(s)
Veerasamy Ravichandran, A S. Khan, Peter E. Barker, G B. Vasquez, S J. Zullo, Talapady N. Bhat, G L. Gilliland
A publicly available web-based resource, the Human Mitochondrial Protein Database (HMPD), has been developed to unify data from a broad collection of related resources that provides information about human nuclear and mitochondrial-encoded proteins. This

Hydraulically Pumped Cone Fracture in Bilayers With Brittle Coatings

October 12, 2021
Author(s)
H Chai, Brian R. Lawn
An earlier FEM analysis of inner cone cracks in monolithic brittle solids subject to cyclic indentation in liquids is extended to include the case of a brittle layer bonded to a compliant substrate, using a model glass/polycarbonate bilayer system as an

Hydrodynamic Flow in Capillary-Channel Fiber Columns for Liquid Chromatography

October 12, 2021
Author(s)
R Stanelle, Lane C. Sander, R K. Marcus
The evaluation of the basic flow characteristics of capillary-channeled polymer (C-CP) fibers proposed for use as the stationary phases for reversed-phase liquid chromatographic separations has been investigated. Stainless steel HPLC columns packed with

Hydrogel-Immobilized Antibodies for Microfluidic Immunoassays

October 12, 2021
Author(s)
Gloria Thomas, Emad E. El-Giar, Laurie E. Locascio, Michael J. Tarlov
The integration of immunoassays in microfluidic devices is a rapidly developing research area combining the power of immunoassays with the inherent benefits of microfluidics. Here, a general overview of microfluidic-based immunoassays is presented along

Hydrolysis-Controlled Transport of Water in Polymeric Coatings

October 12, 2021
Author(s)
Sanghun Lee, Tinh Nguyen, Jonathan W. Martin, E Byrd
Thermoset acrylic melamine coatings are widely used for exterior structures. These materials are formulated by reacting an acrylic polyol with an alkylated melamine. Because the reactions are reversible, acrylic-melamine coatings tend to hydrolyze during

Imidazolium Modified Clay Based ABS Nanocomposites: A Comparison Between Melt-Blending and Solution Sonication Processes

October 12, 2021
Author(s)
M Modesti, S Besco, A Lorenzetti, Mauro Zammarano, V Causin, C Marega, Jeffrey W. Gilman, D M. Fox, Paul C. Trulove, Hugh C. De Long, P H. Maupin
Acrylonitrile-butadiene-styrene (ABS) nanocomposites containing imidazolium-modified montmorillonite have been prepared by melt-blending and solution-sonication in order to study the effects of processing on the morphology and properties of the polymer

Immunomodulatory Effects of Macrolide Antibiotics in Sulfur Mustard Exposed Airway Epithelial Cells: Quantum Dots-Mediated Immunocytochemical Analysis of iNOS and Diaminofluorescein-Mediated Flow Cytometric Analysis of Intracellular Nitric Oxide

October 12, 2021
Author(s)
X P. Gao, Radharaman Ray, Yan Xiao, Peter E. Barker, Prabhati Ray
Exposure of airway epithelial cells to 100 uM sulfur mustard significantly upregulated induced nitric oxide (iNOS) in cells. This response, quantitated by both flow cytometry and quantum dot-visualized antibodies, is returned to normal iNOS levels if cells

Imperfect Surface Order and Functionalization in Vertical Carbon Nanotube Arrays Probed by Near Edge X-ray Absorption Fine Structure Spectroscoy (NEXAFS)

October 12, 2021
Author(s)
T Hemraj-Benny, S Banerjee, S Sambasivan, Daniel A. Fischer, G Eres, Alexander Puretzky, David B. Geohegan, D H. Lowndes, J A. Misewich, S S. Wong
Probing surface order in nanotube systems is of fundamental importance for incorporation of these materials into practical electronic devices. The current study pertains to analysis of the surface orientation of vertically aligned single-walled and multi

Improved Facility for Optical Detector Characterization

October 12, 2021
Author(s)
T Flournoy, George P. Eppeldauer
The detector characterization and calibration facility of the Army Primary Standards Laboratory (APSL) has been extended. In addition to the traditional filter and monochromator based spectral measurements, laser-based sphere sources and high performance
