High Throughput Methods for Polymer Nanocomposites Research: Extrusion, Nmr Characterization and Flammability Property Screening.

November 1, 2003
Author(s)
Jeffrey W. Gilman, S Bourbigot, John R. Shields, Marc R. Nyden, Takashi Kashiwagi, Rick D. Davis, David L. VanderHart, W Demory, C A. Wilkie, A B. Morgan, J R. Harris, R Lyon
Several, recent, revolutionary advances in combinatorial (or high throughput, HT) polymer science have appeared in the literature, which significantly accelerate the rate of data generation. Although these new HT approaches may in part have been inspired

Infrared Spectra of trans-HOCO, HCOOH + , and HCO 2 - Trapped in Solid Neon

November 1, 2003
Author(s)
D Forney, Marilyn E. Jacox, Warren E. Thompson
When a Ne: HCOOH sample is codeposited at ca. 5 K with neon atoms that have been passed through a microwave discharge, new absorptions appear in the infrared spectrum of the resulting solid which can be assigned to trans-HOCO, trans-HCOOH +, and HCO 2 -

MatML: A Data Interchange Markup Language

November 1, 2003
Author(s)
J G. Kaufman, E F. Begley
This paper updates and expands upon previously published information on MatML, a new extensible markup language designed specifically for the exchange of materials information. In particular, it will describe the strengths of MatML from the perspective of

Microscopy and Spectroscopy of Lithium Nickel Oxide Based Particles Used in High-Power Lithium-Ion Cells

November 1, 2003
Author(s)
D Abraham, R D. Twesten, Mahalingam Balasubramanian, J Kropf, Daniel A. Fischer, James McBreen, I Petrov, K Amine
Structural and electronic investigations were conducted on lithium nickel oxide based particles used in positive electrodes of 18650-type high power lithium-ion cells. K-edge X-ray absorption spectroscopy (XAS) revealed trivalent Ni and Co ions in the bulk

Multimodal Biometrics: Issues in Design and Testing

November 1, 2003
Author(s)
Robert D. Snelick, Michael D. Indovina, James H. Yen, Alan Mink
The results of experimental studies on multimodal biometric systems for small-scale populations have shown better performance compared to single-mode biometric systems. We examine if such techniques scale to larger populations, introduce a methodology to

Network Security Testing

November 1, 2003
Author(s)
Shirley M. Radack
This ITL Bulletin summarizes NIST Special Publication 800-42, Guideline on Network Security Testing, by John Wack, Miles Tracy, and Murugiah Souppaya, which assists organizations in testing their Internet-connected and operational systems. The guide

NIST Research Library Exhibits Treasures of Metric History

November 1, 2003
Author(s)
H Hassler
In celebration of National Metric Week (October 6-10, 2003), the NIST Research Library launched a new exhibit featuring important works on the history of the metric system that are part of the Library's Historical Book Collection. Works featured include

NIST XML Simulation Interface Specification at Boeing: A Case Study

November 1, 2003
Author(s)
R F. Lu, Guixiu Qiao, Frank H. Riddick, Charles R. McLean
Efficient and consistent simulation data management is indispensable and a challenging problem to be solved in modeling manufacturing and business processes. An extensible markup language (XML) based simulation interface specification is being developed by

On the Interaction of a Liquid Droplet with a Pool of Hot Cooking Oil

November 1, 2003
Author(s)
Samuel L. Manzello, Jiann C. Yang, Thomas G. Cleary
An experimental study is presented for distilled water droplets impacting on a heated pool of cooking oil. The impaction process was recorded using a high-speed digital camera at 1000 frames per second. The initial droplet diameter was fixed at 3.1+0.1 mm

Optical Photomask CD Metrology at NIST

November 1, 2003
Author(s)
James E. Potzick
Our customers usually measure mask features in order to make a business decision, such as whether or not to ship a mask to a customer. A simple cost/benefit model for mask CD metrology shows there is an optimum measurement uncertainty which will maximize

Phase Equilibria, Crystal Structures, and Dielectric Anomaly in the BaZrO 3 -CaZrO 3 System

November 1, 2003
Author(s)
Igor Levin, T G. Amos, S M. Bell, L Farber, Robert S. Roth, Terrell A. Vanderah, B H. Toby
Phase equilibria in the (1-x)BaZrO 3-xCaZrO 3 system were analyzed using a combination of X-ray and neutron powder diffraction, and transmission electron microscopy. The proposed phase diagram features two extended two-phase fields containing mixtures of a

Polymer-derived SiCN composites with magnetic properties

November 1, 2003
Author(s)
Atanu Saha, Sandeep R. Shah, Rishi Raj, Stephen E. Russek
Composites consisting of particles of α-iron dispersed in silicon carbonitride (SiCN) were fabricated by a polymer route. The composites had iron inclusions with the same magnetization as bulk iron, but they resisted oxidation up to 500°C and had a

Premixed Calcium Phosphate Cement Pastes

November 1, 2003
Author(s)
Shozo Takagi, Laurence C. Chow, S Hirayama, A Sugawara
A self-hardening calcium phosphate cement (CPC-I), consisting of tetracalcium phosphate (TTCP) and dicalcium phosphate anhydrous (DCPA), has been shown in clinical studies to be efficacious as bone repair materials. The hardening time (HT) of the cement is

PVTx and Isochoric Heat Capacity Measurements for Aqueous Methanol Solutions

November 1, 2003
Author(s)
M M. Aliev, Joe W. Magee, I M. Abdulagatov
Isochoric heat capacity and PVTx properties of an aqueous methanol solution (050 mass fraction or 0.36 mol fraction of methanol) were measured in the liquid phase with a twin-cell adiabatic calometer. Temperatures ranged from 333 K to 422 K, and pressures
