Mass Spectrometry Characterization for Chemoenzymatic Glycoprotein Synthesis

July 1, 2011
Author(s)
John E. Schiel, Mark Lowenthal, Karen Phinney
Glycoproteins exist as heterogeneous mixtures of glycoforms due to glycosylation at multiple sites with various glycans. The glycosylation pattern has significant implications for clinical diagnostics and biopharmaceutical development because it affects

Pressure Controlled Advanced Distillation Curve Analysis on Biodiesel Fuels

March 27, 2011
Author(s)
Bret Windom, Tara Lovestead, Thomas J. Bruno
Biodiesel fuel is an alternative fuel that can be derived from a number of renewable feedstocks including plant and vegetable oils, algae, animal fats, waste oils, etc. The fatty acid methyl ester (FAME) profile, and thus the resultant properties, of the

Spatial Coherence in Electron-Beam Patterning

September 27, 2010
Author(s)
Ginusha M. Perera, Gila E. Stein, James Alexander Liddle
We demonstrate a simple method to identify noise sources in electron-beam systems and accurately quantify the resulting errors in feature placement. Line gratings with a 46 nm average pitch were patterned with electron-beam lithography (EBL) and measured

Space-based photometric precision from ground-based telescopes

July 1, 2010
Author(s)
Peter C. Zimmer, John T. McGraw, Anthony B. Hull, Daniel C. Zirzow, Steven Brown, Claire E. Cramer, Gerald Fraser, Keith R. Lykke, Allan W. Smith, John T. Woodward IV, Christopher W. Stubbs, Mark R. Ackermann, Dean C. Hines
Ground-based telescopes supported by lidar and spectrophotometric auxiliary instrumentation can attain space-based precision for all-sky photometry, with uncertainties dominated by fundamental photon counting statistics. Earth‟s atmosphere is a wavelength-

Accurate light-time correction due to a gravitating mass

June 7, 2010
Author(s)
Neil Ashby, Bruno Bertotti
This technical paper of mathematical physics arose as an aftermath of the 2002 Cassini experiment, in which the PPN parameter γ was measured with an accuracy ς γ = 2.3 × 10 -5 and found consistent with the rediction γ=1 of general relativity. The Orbit

Material properties and fractography of an Indirect Dental Resin Composite.

February 23, 2010
Author(s)
Janet B. Quinn, George D. Quinn
Objectives: Determination of material and fractographic properties of a dental indirect resin composite material. Methods: A resin composite (Paradigm, 3M-ESPE, MN) was characterized by strength, static elastic modulus, Knoop hardness, fracture toughness

Author(s)
Robert E. Chapman, David T. Butry, Allison L. Huang, Douglas S. Thomas
This report focuses on a critical analysis of the economic impacts of research conducted by BFRL s Service Life Prediction (SLP) Program for High-Performance Polymeric Construction Materials. The SLP Program is an interdisciplinary research effort within

Anomalous thermal behavior in microcalorimeter gamma-ray detectors

July 20, 2009
Author(s)
Robert D. Horansky, James A. Beall, Kent D. Irwin, Joel N. Ullom
Improving the resolution of gamma-ray detectors is important for many fields, including determinations of the Lamb shift in atoms with high atomic numbers , nuclear treaty verification , and environmental monitoring. High-purity germanium detectors are

A Materials Science-Based Approach to Characterizing Fire Resistive Materials

April 9, 2009
Author(s)
Dale P. Bentz, Christopher C. White, Kuldeep R. Prasad, Daniel R. Flynn, Donald L. Hunston, Kar T. Tan
While ASTM E119-07a is commonly employed to establish a fire rating for a fire resistive material (FRM)/steel assembly, the test method provides little quantitative information on either the thermophysical or adhesion properties of the FRM, beyond
