Adhesive bonding to dentin improved by polymerizable cyclodextrin derivatives

January 5, 2009
Author(s)
Rafael L. Bowen, Gary E. Schumacher, Anthony A. Giuseppetti, Kathleen M. Flynn, Charles M. Guttman, Clifton M. Carey
Objectives. Determine bonding characteristics of a hydrophilic monomer formulation containing PCDs (Polymerizable Cyclodextrin Derivatives). The hypothesis was that a formulation containing hydrophilic cross-linking diluent comonomers and PCD molecules

ADVANCED NON-DESTRUCTIVE HYDROGEN SENSORS TO PREVENT MATERIAL DEGRADATION FROM HYDROGEN DAMAGE

January 5, 2009
Author(s)
Angelique N. Lasseigne, Kamalu Koenig, David Olson, Brajendra Mishra, Joshua Jackson, Thomas A. Siewert, Joseph D. McColskey
New higher strength pipeline steels (X100 and X120) exhibit lower tolerance for hydrogen (diffusible and formed hydrides) before significant degradation or failure occurs. It is essential to have advanced sensors to monitor the hydrogen content and

Instrumented Impact Test: Impact Machine Variables and Specimen Position

January 5, 2009
Author(s)
Christopher N. McCowan
An investigation has been conducted on the influence of impact machine variables and specimen positioning on characteristic forces and absorbed energies from instrumented Charpy tests. Brittle and ductile fracture behavior has been investigated by testing

Measuring optical waveforms with fiber frequency combs

January 5, 2009
Author(s)
Ian R. Coddington, William C. Swann, Nathan R. Newbury
A stabilized frequency comb provides a broadband array of highly resolved comb lines. Using a multiheterodyne technique, we measure the amplitude and phase of every comb line, allowing for massively parallel, high-resolution optical sampling.

Multiplexed Readout of CMB Polarimeters

January 5, 2009
Author(s)
Kent D. Irwin
This paper describes contributions to the workshop, 'Technology Development for a CMB Probe of Inflation,' held at NIST in Boulder CO, Aug. 25-28, 2008 concerning technologies to read out direct detectors (including bolometers and microwave kinetic

NIST Time and Frequency Bulletin

January 5, 2009
Author(s)
Eyvon Petty
The Time and Frequency Bulleting provides information on performance of time scales and a variety of broadcasts (and related information) to users of the NIST services.

On The Security Performance of Physical-Layer Network Coding

January 5, 2009
Author(s)
Yi Qian, Kejie Lu, Shengli Fu, Tao Zhang
Physical-layer network coding (PLNC) is a novel wireless communication technology, in which multiple transmitters can send signals on the same channel to the same receiver at the same time. Our previous studies have revealed that PLNC can substantially

Optimization of photon pair generation in dual-element PPKTP waveguide1

January 5, 2009
Author(s)
Xiao Tang, Oliver T. Slattery, Lijun Ma
A compact scheme for high-speed frequency doubling and down-conversion on a single dual-element PPKTP waveguide is investigated. Optimal temperature is achieved and photon pair coincidence is observed at over GHz repetition rate with pulsed pump input

A Low-Cost Density Reference Phantom for Computed Tomography

January 2, 2009
Author(s)
Zachary H. Levine, Ming-Dong Li, Anthony P. Reeves, David F. Yankelevitz, Joseph J. Chen, Eliot L. Siegel, Adele P. Peskin, Diana N. Zeiger
We have characterized a commercially-available polyurethane foam which is marketed for modeling parts in the aircraft, automotive, and related industries. We find that the foam may be suitable for use as a density reference standard in the range below -700

SRM NIST Standard Reference Materials Catalog, January 2009

January 2, 2009
Author(s)
Joan C. Sauerwein, Regina R. Montgomery
NIST Standard Reference Materials (SRMs) are used by industry, government, and academia to ensure the highest quality measurements. This catalog lists over 1100 individual reference materials produced and sold by NIST, each with carefully assigned values

A vacuum manifold for rapid world-to-chip connectivity of complex PDMS microdevices

January 1, 2009
Author(s)
Gregory A. Cooksey, Anne L. Plant, Francisco J. Atencia
The lack of simple interfaces for microfluidic devices with a large number of inlets significantly limits production and utilization of these devices. In this paper, we describe the fabrication of a reusable manifold that provides rapid world-to-chip
