Nanoscale Switch Elements From Self-Assembled Monolayers on Silver

October 16, 2008
Author(s)
J M. Beebe, James G. Kushmerick
Au/molecule/Ag junctions are shown to behave as voltage-controlled two-state switches. In the open state, the current-voltage behavior is consistent with a metal-molecule-metal tunnel junction. At a negative bias threshold, silver filaments bridge the gap

Nanotechnology Research of NIST Scientists at JILA

October 16, 2008
Author(s)
S R. Leone
NIST scientists participate in a variety of nanotechnology activities, several of which are summarized here. The drive toward both ever-smaller integrated circuits, new materials, biosensors, and improved control of catalysis all rely on quantitative and

Nature Materials News and Views on T. Haxhimali et al

October 16, 2008
Author(s)
James A. Warren
Simulations of dendritic solidification by T. Haxhimali et al. [1] for a pure material and comparisons with experiments in an A1Zn alloy system have shown that a standard theoretical rule of thumb for predicting solidification growth forms can dramatically

Near-Critical Behavior of Aqueous Systems

October 16, 2008
Author(s)
M A. Anisimov, Jan V. Sengers, Johanna Levelt Sengers
This chapter concentrates on the thermophysical properties of water, steam and aqueous solutions in a large range around the water critical point. The chapter is written for a technically knowledgeable audience without specialized background in fluid

Neutron Irradiation in Activation Analysis: A New Rabbit for the NBSR

October 16, 2008
Author(s)
Richard M. Lindstrom, Rolf L. Zeisler, Elizabeth A. Mackey, P J. Liposky, Rachel S. Popelka-Filcoff, Robert E. Williams
Elementary activation analysis assumes that the reaction rate is proportional to the number of atoms of analyte present in the sample. On close examination, this is not always true, even within a set of samples irradiated together. For accurate analysis

Neutron Reflectivity for Interfacial Materials Characterization

October 16, 2008
Author(s)
Eric K. Lin, D J. Pochan, R Kolb, Wen-Li Wu, Sushil K. Satija
Measurements of the physical properties of materials, such as the coefficient of thermal expansion (CTE), in thin films and at interfaces are very important in microelectronics packaging and interconnection, especially as electronic devices decrease in

New Approaches to Serving Library Users

October 16, 2008
Author(s)
C L. Clark
The NIST Research Library serves over 3,000 Science & Technology customers; provides access to 200,000 items, 1,000 journal subscriptions, 700 databases; performs services using the team approach; hosts NIST Virtual Library (NVL); resides online at http:/

New Critical Compilations of Atomic Transition Probabilities

October 16, 2008
Author(s)
Wolfgang L. Wiese, Jeffrey R. Fuhr, Daniel E. Kelleher, Larissa Podobedova
At the National Institute of Standards and Technology (NIST), we are continuing our critical evaluation and compilation work on atomic transition probabilities. We have recently concentrated our efforts on the spectra of Na, Mg, Al, Si and S for all stages

New Working Standards to Disseminate NIST Radiometric and Photometric Scales

October 16, 2008
Author(s)
George P. Eppeldauer, Richard Austin, Charles Lustenberger
A new generation radiometer-photometer system has been developed in a National Institute of Standards and Technology (NIST) and Gamma Scientific (GS) cooperation to satisfy the increased requirements in the dissemination of NIST responsivity scales. The

NIST 1. NIST/EPA/NIH Mass Spectral LibraryNIST '98 ASCII Version

October 16, 2008
Author(s)
Stephen E. Stein
NIST '98 is a fully evaluated collection of electron-ionization mass spectra. It is the product of a ten-year effort by a team of experienced mass spectrometrists in which each spectrum was examined for correctness.This has led to thousands of selections

NIST 14. NIST Mixture Property Database

October 16, 2008
Author(s)
Daniel G. Friend
The NIST Mixture Property Database calculates thermodynamic and transport properties of mixtures of fluids selected from any of 17 possible pure components. The emphasis of the database is on density prediction (especially for CO2-rich mixtures), but for

NIST 15. NIST/Sandia/ICDD Electron Diffraction Database

October 16, 2008
Author(s)
Vicky L. Karen
Designed for phase characterization obtained by electron diffraction methods, this database and associated software permit highly selective identification procedures for microscopic and macroscopic crystalline materials.The database contains chemical
