Embedded Capacitive Displacement Sensor for Nanopositioning Applications

July 1, 2011
Author(s)
Svetlana Avramov-Zamurovic1, Nicholas Dagalakis, Rae Duk Lee, Jae M. Yoo, Seung H. Yang
The scale of nano objects requires very precise position determination. The state-of-the-art manipulators involve accurate nanometer positioning. The paper presents the design, fabrication process and testing of a capacitance based displacement sensor

Evaluating the characteristics of multiwall carbon nanotubes

July 1, 2011
Author(s)
John H. Lehman, M. Terrones, Elisabeth Mansfield, Katie Hurst, Vincent Muenier
During the past 20 years, multiwall carbon nanotubes (MWCNTs) have become an important industrial material. Hundreds of tons are produced each year. This review is a survey of the scientific literature, motivated by industrial requirements and guidelines

GaN nanowires grown by molecular beam epitaxy

July 1, 2011
Author(s)
Kristine A. Bertness, Norman A. Sanford, Albert Davydov
The unique properties of GaN nanowires grown by molecular beam epitaxy are reviewed. These properties include defect-free growth mode with no residual strain, long photoluminescence lifetime, low surface recombination velocity and high mechanical quality

Graphene: Materials to devices

July 1, 2011
Author(s)
Jungseok Chae, Jeonghoon Ha, H. Baek, Young Kuk, Suyong S. Jung, Young J. Song, Nikolai B. Zhitenev, Joseph A. Stroscio, S.J. Woo, Y.-W. Son

IEEE TC-10: Update 2011

July 1, 2011
Author(s)
Nicholas G. Paulter Jr., Thomas E. Linnenbrink, W. B. Boyer, S. J. Tilden, Travis Ellis
There is a world-wide need to standardize terms, test methods, and the computation of performance parameters for devices that generate, measure, and analyze waveforms. Users need to be able to unambiguously specify the device performance required for

Investigation of Weak Interlayer Exchange Coupling in the GaMnAs/GaAs Superlattice with Insulating Nonmagnetic Spacers

July 1, 2011
Author(s)
Jae-Ho Chung, Young-Sang Song, Taehee Yoo, Sun-Jae Chung, Sanghoon Lee, Brian Kirby, X. Liu, J. K. Furdyna
A robust long-range antiferromagnetic coupling between ferromagnetic Ga 0.97Mn 0.03As layers has previously been realized via insertion of non-magnetic Be-doped GaAs spacers. In this paper, we report the observation of the weak antiferromagnetic coupling

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
