How Interoperability Saves Money

February 1, 2001
Author(s)
Robert E. Chapman
The pressures of competing in the global marketplace are forcing building control companies, equipment and systems manufacturers, energy providers, utiliites, and design engineers to improve performance and reduce costs. One means of meeting this twin

Information Technology Measurement and Testing Activities at NIST

February 1, 2001
Author(s)
David Flater, James E. Fowler, Simon P. Frechette, Craig M. Shakarji, Michael Hogan, Shirley M. Radack, Douglas Montgomery, L Johnson, R Rosenthal, R Mccabe, R Carpenter, Lisa Carnahan, M M. Gray
Our high technology society continues to rely more and more upon sophisticated measurements, technical standards, and associated testing activities. This was true for the industrial society of the 20th century and remains true for the information society

Investigation and Control of Spatial Characteristics of Chamber-Cleaning Plasmas

February 1, 2001
Author(s)
Kristen L. Steffens, Mark A. Sobolewski
Planar laser-induced fluorescence (PLIF) measurements were made to determine 2-D spatial maps of CF2 density as a chemical marker of plasma uniformity in 9%O2/91%CF4 chamber-cleaning plasmas. Measurements were made in the capacitively-coupled Gaseous

Laminar Flow of Four Gases Through a Helical Rectangular Duct

February 1, 2001
Author(s)
Robert F. Berg, S A. Tison
We report measurements and a model of gas flow through a helical duct of rectangular cross section. The measurements on helium, nitrogen, argon, and sulfur hexafluoride yielded molar flow rates from observations of the rate of rise of pressure in a known

Length and Dimensional Measurements at NIST

February 1, 2001
Author(s)
Dennis A. Swyt
This paper reports on the past, present, and future of length and dimensional measurements at NIST. It covers the evolution of the SI unit of length through its three definitions and the evolution of NBS-NIST dimensional measurement from early linescales

Manganese(III) Biliverdin IX Dimethyl Ester: A Powerful Catalytic Scavenger of Superoxide Employing the Mn(III)/Mn(IV) Redox Couple

February 1, 2001
Author(s)
I Spasojevic, I Batinic-Haberle, R D. Stevens, P Hambright, A N. Thorpe, J Grodkowski, Pedatsur Neta, I Fridovich
A manganese(III) complex of biliverdin IX dimethyl ester, Mn IIIBVDME} 2 was prepared and characterized by elemental analysis, uv/vis spectroscopy, cyclic voltammetry, chronocoulometry, electrospray mass spectrometry, freezing-point depression, magnetic

Mass Spectrometry: Proton Affinities

February 1, 2001
Author(s)
E P. Hunter, S G. Lias
This article presents a short review for a general reader of determinations of proton affinities and basicites in the gas phase. The evaluation of the scale of proton affinities and gas phase basicities is described.

Materials Research With Neutrons at NIST

February 1, 2001
Author(s)
Ronald L. Cappelletti, Charles J. Glinka, Susan T. Krueger, Richard M. Lindstrom, Jeffrey W. Lynn, Henry J. Prask, E Prince, John J. Rush, J. Michael Rowe, Sushil K. Satija, B H. Toby, A. Tsai, Terrence J. Udovic

Measuring Antennas Above 1 GHz

February 1, 2001
Author(s)
Michael Windler, Dennis G. Camell
The techniques for EMC measurements used with antennas above 1 GHz have been gleaned from methods used at lower frequencies. The assumptions made in applying these techniques have not been completely validated. This analysis will compare antennas for use

Morphological and Phase Characterizations of Retrieved Calcium Phosphate Cement Implants

February 1, 2001
Author(s)
Shozo Takagi, Laurence C. Chow, Milenko Markovic, C D. Friedman, P D. Costantino
A self-hardening calcium phosphate cement (CPC), consisting of equimolar amounts of tetracalcium phosphate and dicalcium phosphate anhydrous, hardens when mixed with water and forms a resorbable hydroxyapatite (HA) as the end- product. The objective of

Nanomechanical Characterization of Polymers Using Scanning Probe Microscopes

February 1, 2001
Author(s)
Mark R. VanLandingham
Scanning probe microscopy (SPM) has been used to study polymeric materials with nanometer spatial resolution. Indentation methods based on SPM technology include the use of cantilever probes with an atomic force microscope (AFM), depth-sensing transducers

NIST Workshop on Reference Data for the Properties of Biomaterials

February 1, 2001
Author(s)
John A. Tesk
The needs for reference data on properties of biomaterials were identified at a workshop held at the National Institute of Standards and Technology (NIST) on July 27, 2000 and co-organized by NIST and the Society of Biomaterials. The 65 registrants from
