Mass Spectrometry Characterization for Chemoenzymatic Glycoprotein Synthesis

July 1, 2011
Author(s)
John E. Schiel, Mark S. Lowenthal, Karen W. 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

Messaging Work Bench Instructions

July 1, 2011
Author(s)
Ioana Singureanu
Documentation on using the Messaging Workbench (MWB) tool to edit the profile created for the NCPDP SCRIPT Implementation Guide: Version 10.6 NEWRX New Prescription and RXHRES Prescription History Response message structures.

Model Based Enterprise for Manufacturing

July 1, 2011
Author(s)
Simon P. Frechette
A Model-Based Enterprise (MBE) is an organization that applies modeling and simulation technologies to integrate and manage its technical and business processes related to production and product lifecycle support. By using product and process models to

Porous Graphene Oxide Frameworks: Synthesis and Gas Sorption Properties

July 1, 2011
Author(s)
Gadipelli Srinivas, Jacob Burress, Jamie Ford, Taner Yildirim
We report detailed synthesis of a range of porous graphene oxide frameworks (GOFs) by expansion of graphene oxide (GO) sheets with various linear boronic acid pillaring units in a solvothermal reaction. The GOF structures develop through boronate-ester

Stable isotope-labeling of DNA repair proteins, and their purification and characterization

July 1, 2011
Author(s)
M Miral Dizdar, Pawel Jaruga, Prasad T. Reddy, Bryant C. Nelson, Mark S. Lowenthal
Reduced DNA repair capacity is associated with increased risk for a variety of disease processes including carcinogenesis. Thus, DNA repair proteins have the potential to be used as important predictive, prognostic and therapeutic biomarkers in cancer and

Vacuum technology considerations for mass metrology

July 1, 2011
Author(s)
Patrick J. Abbott, Zeina J. Kubarych
Vacuum weighing of mass artifacts eliminates the necessity of air buoyancy correction and its contribution to the measurement uncertainty. Vacuum weighing is also an important process in the experiments currently underway for the redefinition of the SI

Characterization of Three Berry Standard Reference Materials for Nutrients

June 30, 2011
Author(s)
Laura J. Wood, Katherine E. Sharpless, Monique Pichon, Barbara J. Porter, James H. Yen
The National Institute of Standards and Technology (NIST) has been working with the National Institutes of Health Office of Dietary Supplements to produce Standard Reference Materials (SRMs) of interest to analysts of dietary supplements. Some of these

Recent Developments in Millimeter and Submillimeter Metrology at NIST

June 30, 2011
Author(s)
Ronald A. Ginley
The millimeter and submillimeter frequency ranges are becoming very important to today’s electronics, security and communication industries. NIST has undertaken a research program to aggressively pursue this area. This paper will cover the millimeter

Density and Speed of Sound Measurements of Two Synthetic Aviation Turbine

June 29, 2011
Author(s)
Stephanie L. Outcalt, Tara J. Fortin
Rising prices and the uncertain supply of petroleum based aviation fuels have led to an interest in substitute fuels made from non-petroleum sources. Synthetic isoparaffinic kerosenes (S-IPK) are among the most promising alternatives. Two instruments were

Formation of stacking faults and their correlation with flux-pinning and critical current density for Sm-doped YBa2Cu3O7-x films

June 29, 2011
Author(s)
Winnie K. Wong-Ng, Sung H. Wee, Eliot D. Specht, Claudia Cantoni, Jonathan Zuegel, Victor Maroni, Guangyao Liu, Timothy J. Haugan, Amit Goyal
A correlation between flux-pinning characteristics and stacking faults (SFs) formed by Sm substitution on Y and Ba sites was found in Sm-doped YBCO films. It was confirmed that “223” type SFs, Y2Ba2Cu3Ox, composed of Y and O extra planes aligned parallel

Guided three-dimensional catalyst folding during Metal assisted Chemical Etching of Silicon

June 28, 2011
Author(s)
Konrad Rykaczewski, Owen J. Hildreth, Ching P. Wong, Andrei G. Fedorov, John H. Scott
In order to fabricate truly complex three-dimensional (3D) silicon nanostructures fabrication methods which expand beyond the concept of creation of straight 3D structures by direct extension of two dimensional (2D) patterns need to be developed. In recent
