Investigation of N 2 Plasma Effects on the Depth Profile of Hydrogen Silsesquioxane Thin Films Using High Resolution Specular X-Ray Reflectivity

October 16, 2008
Author(s)
Hae-Jeong Lee, Eric K. Lin, J K. Lan, Y L. Cheng, H C. Liou, Wen-Li Wu, Y L. Wang, M S. Feng, C G. Chao
Non-destructive, specular X-ray reflectivity (SXR) measurements were used to investigate N2 plasma effects on the density depth profile of hydrogen silsesquioxane (HSQ) thin films. The SXR data indicate that the density profile of an HSQ film without

Issues and Trends in Legal Metrology (from a U.S. Perspective)

October 16, 2008
Author(s)
Charles D. Ehrlich, H V. Oppermann
Several current aspects of legal metrology are likely to change significantly over the next 10 years to 20 years. Exponential increase in the use of technology in the marketplace requires legal metrology officials to become increasingly knowledgeable in a

IUPAC/NIST Solubility Database

October 16, 2008
Author(s)
G R. Dalton, Angela Y. Lee, S L. Young
A database containing solubilities originally published in the International Union for Pure and Applied Chemistry (IUPAC)-NIST Solubility Data Series has been made available online. The data were originally published in eleven volumes of the Solubility

Key Concepts in Evaluating Outcomes of ATP Funding of Advanced Technologies

October 16, 2008
Author(s)
Andrew J. Wang
The Economic Assessment Office (EAO) of the Advanced Technology Program (ATP) commissions economic studies by outside research organizations. A recent study by the Research Triangle Institute (RTI) outlines a framework for evaluating ATP funding of medical

Kinetic Simulations of Crystal Growth With (Nearly) Realistic Physics

October 16, 2008
Author(s)
J L. Blue
Many kinetic Monte Carlo simulations of expitaxial crystal growth have been done using a simple cubic crystal structure and over-simplified physics. We discuss how to improve these simulations in a general-purpose computer program that can handle correct

Kinetics of Polymer Phase Separation

October 16, 2008
Author(s)
Charles C. Han
Kinetics of polymer phase separation has been briefly reviewed. This is a section on this subject for Encyclopedia of Materials: Science and Technology. This section includes summary of sinodal decomposition, critical temperature shift under shear flow

Knowledge and Uniformity

October 16, 2008
Author(s)
H V. Oppermann
Two primary objectives of weights and measures enforcement are to promote fair competition among companies and to ensure accurate measurement for consumers. To achieve these objectives, it is necessary to have knowledgeable weights and measures officials

Laboratory Experiments for Fundamental Physics in Space

October 16, 2008
Author(s)
William D. Phillips
Laboratory Experiments refers generally to active spaceborne experiments as opposed to the equally important passive observation in space of signals coming from more distant sources. My purpose in this presentation is to highlight a number of opportunities

Large Scale MCHF Calculation of the Li I 4d-4f Energy Difference

October 16, 2008
Author(s)
C F. Fischedr, Y Ralchenko
The calculational methods in atomic structure are currently capable of providing the level of accuracy close to that of the most precise experiments. The multiconfiguration Hartee-Fock method is applied to calculation of the 4d 4f energy difference in Li I

LBIR Facility Five Year Plan (FY05-FY09)

October 16, 2008
Author(s)
Adriaan C. Carter, Raju V. Datla
This NIST Low Background Infrared (LBIR) Calibration facility has become a national center for the development and dissemination of absolute standards and their traceability for the measurement of low level infrared radiation. The five year (FY 05 to FY 09

Lessons Learned About the Methodology of Economic Impact Studies

October 16, 2008
Author(s)
Gregory C. Tassey
Pressures on U. S. government S&T agencies to measure the economic impacts of their research programs have increased due to general pressures on the discretionary portion of the Federal budget and specific pressures to comply with the Government

Letter to the Editor Creep of Consolidated Silver

October 16, 2008
Author(s)
H J. Mueller, F Eichmiller
This letter to the editor is in regard to a recent publication (Indentation Creep Behavior of a Direct-filling Alternative to Amalgam by H.H.K. Xu, H. Liao, and F.C. Eichmiller, J. Dent. Res. 77:1991, 1998), whereby the authors overlooked the citation of a

Limits on Toughening in Structural Adhesives

October 16, 2008
Author(s)
Donald L. Hunston, H Jianmei, R Raghavan, D Hoffman
The addition of a toughener to a thermoset resin, usually an epoxy, can increase the fracture energy by an order of magnitude or more. These materials are two phase systems with small toughener particles in a thermoset matrix. The fracture behavior depends
