Development of the Web-Based NIST X-Ray Photoelectron Spectroscopy (XPS) Database

January 1, 2002
Author(s)
Angela Y. Lee, D M. Blakeslee, Cedric J. Powell, J R. Rumble
The first web-based version of the NIST X-ray Photoelectron Spectroscopy Database (XPSDB) is described. The current database, built from a relational database management system (RDBMS), contains critically evaluated data with over 19,000 line positions

Diffraction Corrections in Radiometry: A Proposed Method to Estimate Uncertainties

January 1, 2002
Author(s)
Eric L. Shirley, Raghu N. Kacker, Raju V. Datla
Radiometric determination of certain quantities, such as source radiance, geometrical aspects of an optical system (e.g., throughput, aperture areas and detector response relies heavily on the mathematical principles governing geometrical optics. These

Displacement Uncertainty in Interferometric Radius Measurements

January 1, 2002
Author(s)
William T. Estler, Tony L. Schmitz, Angela Davies, Christopher J. Evans
Interferometric radius measurements may be completed using a radius bench, where radius is defined as the displacement between the confocal and cat''s eye nulls (identified using a figure measuring interferometer). Measurements of a Zerodur sphere have

Effect of Thermal Cycling on Whisker-Reinforced Dental Resin Composites

January 1, 2002
Author(s)
H H. Xu, F Eichmiller, Douglas T. Smith, Gary E. Schumacher, Anthony A. Giuseppetti, Joseph M. Antonucci
The mechanical properties of dental resin composites needs to be improved in order to extend their use to high stress-bearing applications such as crown and bridge restorations. Recent studies used single crystal ceramic whiskers to reinforce dental
