Quantifying Interfacial Adhesion in Transfer Printing via a Cantilever Peel Test

April 6, 2008
Author(s)
Jiong Liu, Jun Y. Chung, Christopher Stafford
Transfer printing has been demonstrated as a fabrication method for flexible organic electronics. The transfer printing process relies on the differential adhesion of a printable layer (PL) that is pressed between two substrates: transfer substrate (TS)

Status and Recent Trends in Cryocooler Research

April 6, 2008
Author(s)
Ray Radebaugh
The five types of cryocoolers used to provide cryogenic temperatures for various applications are the Joule-Thomson, Brayton, Stirling, Gifford-McMahon, and pulse tube cryocoolers. Many advances in all types have occurred in the past twenty years that have

Synthesis and Characterization of Polymer Brushes from PDMS Surfaces

April 6, 2008
Author(s)
Heqing Huang, Adam J. Nolte, Jun Y. Chung, Christopher Stafford
In recent years, poly(dimethylsiloxane) (PDMS) has found increased application in the areas of microfluidic devices, chromatographic packing materials and membranes, as well as in medical and drug delivery devices. However, the hydrophobic surface of PDMS

Demonstration of a quantum controlled-NOT gate in the telecom band

April 4, 2008
Author(s)
Jun Chen, Joseph B. Altepeter, Milja Medic, Fook L. Kim, Burc Gokden, Robert Hadfield, Sae Woo Nam, Prem Kumar
We present the first quantum controlled-NOT (CNOT) gate realized using a fiber-based indistinguishable photon-pair source in the 1.55 υm telecommunications band. Using this free-space CNOT gate, all four Bell states are produced and fully characterized by

A Relational Approach to the Interactive Analysis of Attack Graphs

April 2, 2008
Author(s)
Lingyu Wang, Chao Yao, Anoop Singhal, Sushil Jajodia
The analysis of attack graphs has played an important role in defending against network intrusions. This paper presents a relational approach. We devise a relational approach to model necessary inputs and network configurations to generate attack graphs.

A Simple Model of Thermally-Induced Electrical Cable Failure

April 2, 2008
Author(s)
Kevin B. McGrattan, Kristopher Overholt
A simple thermal model to predict the failure of electrical power, instrument, and control cables is described. The model is intended as a subroutine for deterministic fire models, and it is of comparable accuracy and simplicity to the activation

TOWARDS A TEST METHOD FOR HYDROGEN SENSOR PERFORMANCE

April 2, 2008
Author(s)
Nathan D. Marsh, Thomas G. Cleary
As part of an effort to develop standard test methods for the performance of commercial hydrogen sensors, we employed the Fire Emulator / Detector Evaluator, an instrumented flow system designed to study the response of fire detectors (smoke, heat, gas)

Uniform and enhanced field emission from chromium oxide coated carbon nanosheets

April 2, 2008
Author(s)
Uwe Arp, Kun Hou, Ronald Outlaw, Wang Sigen, Mingyao Zhu, Ronald Quinlan, Dennis Manos, Martin Kordesch, Brian Holloway
Carbon nanosheets, a two-dimensional carbon nanostructure, are promising electron cathode materials for applications in vacuum microelectronic devices. This letter demonstrates a simple approach to improve the spatial emission uniformity of carbon

A Thermodynamic Study of Ketoreductase-Catalyzed Reactions, Part 5. Reduction of Substituted Ketones in n-Hexane

April 1, 2008
Author(s)
Yadu D. Tewari, David J. Vanderah, Michele M. Schantz, Robert N. Goldberg, J D. Rozzell, J F. Liebman, Raymond W. Hui, Yitzy Nissenbaum, Ahmad R. Parniani
The equilibrium constants K for the ketoreductase-catalyzed reduction reactions of 1-benzyl-3-pyrrolidinone, ethyl 2-oxo-4-phenylbutyrate, ethyl 4-chloroacetoacetate, 1-benzyl-4-piperidone, and 1-benzyl-3-piperidone were measured in n-hexane at T = 298.15

A Two-Way Josephson Voltage Standard Comparison between NIST and NRC

April 1, 2008
Author(s)
Yi-hua Tang, Barry Wood, Clark Hamilton
A two-way Josephson voltage standard (JVS) direct comparison between the National Institute of Standards and Technology (NIST) and the National Research Council (NRC) has been conducted. The process consists of two comparisons, which means that the NIST

Advancement of Light-Element Neutron Depth Profiling at the University of Texas

April 1, 2008
Author(s)
S M. Whitney, Robert Gregory Downing, S Biegalski, D S. O'Kelly
The University of Texas (UT) at Austin has collaborated with the National Institute of Standards and Technology for comparisons of concentration versus depth profiles of samples containing 10B. Technology sharing from NIST has allowed UT to avoid many

BACnet for Utilities and Metering

April 1, 2008
Author(s)
David G. Holmberg, Steven T. Bushby, James J. Butler
The BACnet standard has been expanded to include new object types that are intended for metering and demand management applications, as well as a web services specification that allows any outside service provider access to BAS data. Since the most common

CODATA recommended values of the fundamental physical constants: 2006

April 1, 2008
Author(s)
Peter J. Mohr, Barry N. Taylor, David B. Newell
The paper give the 2006 self-consistent set of values of the basic constants and conversion factors of physics and chemistry recommended by the Committee on data for Science and Technology (CODATA) for international use. Further, it describes in detail the

Collimated spin wave beam generated by a single layer, spin torque nanocontact

April 1, 2008
Author(s)
Mark Hoefer, Thomas J. Silva, M D. Stiles
A model of spin-torque-induced magnetization dynamics based on semiclassical spin diffusion theory for a single-layer nanocontact in presented. The model incorporates effects due to the current-induced Oersted field and predicts the generation of a variety

Computer Security Division 2007 Annual Report

April 1, 2008
Author(s)
Kevin M. Stine, Mark Wilson
Title III of the E-Government Act of 2002, entitled the Federal Information Security Management Act (FISMA) of 2002, requires NIST to prepare an annual public report on activities undertaken in the previous year, and planned for the coming year, to carry
