Extraordinary Flow Characteristics of Nanotube-Filled Polymer Materials

August 2, 2004
Author(s)
S B. Kharchenko, Kalman D. Migler, Jack F. Douglas, Jan Obrzut, E A. Grulke
Carbon nanotubes are under intense investigation due their potential for modifying the electrical conductivity (s), shear viscosity (h) and other transport properties of polymeric materials. They are hybrids of ordinary filler particles and nanoscale

10 kV, 123 m O}-cm 2 4H-SiC Power DMOSFETs

August 1, 2004
Author(s)
Sei-Hyung Ryu, Sumi Krishnaswami, Michael O'Loughlin, James Richmond, Anant Agarwal, John W. Palmour, Allen R. Hefner Jr.
10 kV, 123 mΩ}-cm 2 Power DMOSFETs in 4H-SiC are demonstrated. A 42% reduction in R on,sp, compared to previously reported value, was achieved by using an 8 x 1014 cm-3 doped, 85 υm thick drift epilayer. An effective channel mobility of 22 cm2/Vs was

A Buckling-Based Metrology for Measuring the Elastic Moduli of Polymeric Thin Films

August 1, 2004
Author(s)
Christopher Stafford, Eva Simonyi, C Harrison, Kathryn Beers, Alamgir Karim, Eric J. Amis, Mark R. VanLandingham, H C. Kim, W Volksen, R D. Miller
As technology continues towards smaller, thinner and lighter devices, more stringent demands are placed on thin polymer films as diffusion barriers, dielectric coatings, electronic packaging and so on. Therefore, there is a growing need for testing

A Guide for Creating Conformance Criteria: A How-to Guide with DOs and DON?Ts

August 1, 2004
Author(s)
Lynne S. Rosenthal, Gordon E. Lyon
The goal of this document is to help W3C editors write better specifications, by making a specification easier to interpret without ambiguity and clearer as to what is required in order to conform. It focuses on how to define and specify conformance. It

Analytical Validation of Telomerase Activity for Cancer Early Detection: TRAP/PCR-CE and hTERT mRNA Quantification Assay for High-Throughput Screening of Tumor Cells

August 1, 2004
Author(s)
J P. Jakupciak, Wenhua Wang, Peter E. Barker, S Srivastava, Donald H. Atha
Activation of telomerase plays a critical role in unlimited proliferation and immortalization of cells. Telomerase activity has been shown to correlate with tumor progression, indicating that tumors expressing this enzyme posses aggressive clinical

Assessment of Thin Film UHMWPE Bearings for Precision Slideways

August 1, 2004
Author(s)
E S. Buice, H Yang, Richard Seugling, Stephen J. Smith, R Hocken
In this extended abstract, results from tests on a novel, thin-film, Ultra-High-Molecular-Weight-Polyethylene (UHMWPE) bearing are presented. The goal of this investigation is to assess the performance and manufacture and to determine tribological

Characterization of the Far-Ultraviolet Spectrum of Pt/Cr-Ne Hollow Cathode Lamps as used on the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope

August 1, 2004
Author(s)
Craig J. Sansonetti, Joseph Reader, F Kerber, Michael R. Rosa
We report laboratory measurements to characterize the spectral output of platinum/chromium hollow cathode lamps containing neon carrier gas. The spectrum was recorded photographically with the NIST 10.7-m normal-incidence spectrograph. The lamps
