Laboratory Astrophysics and Microanalysis With NTD-Germanium-Based X-Ray Microcalorimeters

January 1, 2000
Author(s)
E Silver, H. Schnopper, Simon R. Bandler, S Murray, N. Madden, D Landis, J. Beeman, E. E. Haller, M Barbera, G Tucker, John D. Gillaspy, E Takacs, James V. Porto
With the ability to create cosmic plasma conditions in the laboratory it is possible to investigate the dependencies of key diagnostic x-ray lines on density, temperature, and excitation conditions that exist in astrophysical sources with x-ray optics and

Ladars for Construction Assessment and Update

January 1, 2000
Author(s)
Geraldine S. Cheok, William C. Stone, Robert R. Lipman, Christoph J. Witzgall
Work at the National Institute of Standards and Technology (NIST) on laser radar imaging of a construction site is described. The objective of the NIST research is to make measurements required in a construction project quicker and cheaper than current

Layer Perfection in Ultrathin InAS Quantum Wells in GaAs(001)

January 1, 2000
Author(s)
J A. Gupta, S P. Watkins, E D. Crozier, Joseph Woicik, D A. Harrison, D Jiang, I J. Pickering, B A. Karlin
X-ray diffraction (XRD), X-ray standing wave (XSW) and X-ray absorption fine structure (XAFS) measurements were used to assess the layer perfection and positions of 1 and 2 monolayer (ML) InAs quantum wells buried in GaAs(001). Photoluminescence (PL)

Load History Dependence of Fracture in Rubber-Toughened Epoxies

January 1, 2000
Author(s)
Donald L. Hunston, J He, R Raghavan, D Hoffman
It is well know that the most common toughening mechanisms in structural adhesives are viscoelastic processes so the fracture energies for bulk adhesive specimens and bonded joints vary with loading history. The work here examines this effect by measuring
