Uncertainty Budgets for Realization of ITS-90 by Radiation Thermometry

January 1, 2003
Author(s)
J Fischer, M Battuello, M Sadli, M Ballico, S N. Park, P Saunders, Y Zundong, B. Carol Johnson, E Van der Ham, F Sakuma, Graham Machin, N Fox, W Li, S Ugur, M Matveyev
Recent international comparisons [1,2] and key comparisons have shown that the realization of the ITS-90 above the freezing point of silver and its dissemination may be less straightforward than expected. In many cases, the deviations of the local scale

Impedance/Dielectric Spectroscopy of Electroceramics in the Nanograin Regime

December 3, 2002
Author(s)
N Kidner, Z J. Homrighaus, B J. Ingram, T Mason, Edward Garboczi
In the microcrystalline regime, the behavior of grain boundary-controlled electroceramics is well described by the brick layer model (BLM). In the nanocrystalline regime, however, grain boundary layers can represent a significant volume fraction of the

Quantitating Fluorescence Intensity From Fluorophores: Practical Use of MESF Values

July 1, 2002
Author(s)
Lili Wang, Adolfas K. Gaigalas, F Abassi, G E. Marti, R F. Vogt, A Schwarz
The present work uses fluorescein as the model fluorophore and points out critical steps in the use of MESF (Molecules of Equivalent Soluble Fluorophores) values for quantitative flow cytomeric measurements. It has been found that the emission spectrum

Polarized Light Scattering From Metallic Particles on Silicon Wafers

December 1, 2001
Author(s)
Jae H. Kim, S H. Ehrman, George W. Mulholland, Thomas Germer
Polarized light scattering by monodisperse copper and gold spheres, having diameters ranging from 96 nm to 205 nm deposited on silicon substrates were measured using visible light. The results are compared to an exact theory for scattering by a sphere on a
