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

Improved Theoretical X-Ray Resonant Scattering Amplitudes

October 12, 2021
Author(s)
J O. Cross, M I. Bell, M Newville, J J. Rehr, L B. Sorensen, Charles E. Bouldin, G Watson, T Gouder, G H. Lander
Resonant elastic scattering amplitudes [Δ]f = f[u'] + if[u''] in the vicinity of the absorption edges have been obtained by applying a differential Kramers-Kronig transform to theoretical absorption cross-sections calculated by the ab initio x-ray

Improved Transition Oscillator Probabilities for Laser Transitions in Xe I

October 12, 2021
Author(s)
Abhijit Dasgupta, J P. Apruzes, O Zatsarinny, K Bartschat, Charlotte F. Fischer
The atomic xenon laser is among the most efficient and powerful of thenear-infrared gas lasers, especially when pumped by molecular ions in an Ar-Xemixture. Accurate oscillator strengths for the laser transitions are criticaltodeveloping a fundamental
