Ralaxometry and Magnetometry of Ferritin

December 1, 1998
Author(s)
R A. Brooks, J Vymazal, Ronald B. Goldfarb, J W. Bulte, P Aisen
By combining nuclear magnetic ralaxometry on 39 ferritin samples with different iron loading with magnetometry, results were obtained that suggest a new interpretation of the core structure and magnetic properties of ferritin. These studies provide

Resonant Magnetic Field Control of Elastic Scattering in Cold 85Rb

December 1, 1998
Author(s)
J L. Roberts, N R. Claussen, J P. Burke, C H. Greene, Eric A. Cornell, C E. Wieman
A magnetic field-dependent Feshbach resonance has been observed in the elastic scattering collision rate between stoms in the F = 2, M = -2 state of 85Rb. Changing the magnetic field by several Gauss caused the collision rate to vary by a factor of 10 4

Spectral Response Based Calibration Method of Tristimulus Colorimeters

December 1, 1998
Author(s)
George P. Eppeldauer
The accuracy of tristimulus colorimeters can be increased by using detector standards instead of traditional lamp standards for calibration. After high accuracy absolute spectral response determination of the color channels, spectral and amplitude

Spectroradiometric Detector Measurements: Part III--Infrared Detectors

December 1, 1998
Author(s)
Alan L. Migdall, George P. Eppeldauer
The National Institute of Standards and Technology (NIST) supplies calibrations of IR photodetector's spectral radiant power response from 1.8 υm to 20 υm. The spectral responsivity of a detector under test is determined by comparison to an absolute

Spectroscopy of 2-aminopurine: An MCSCF Study

December 1, 1998
Author(s)
E L. Rachofsky, J B. Ross, Morris Krauss, R Osman
2-aminopurine (2AP) is a highly fluorescent isomer of adenine that can be incorporated into DNA as a probe of structure, dynamics, and protein-DNA interactions. Interpretation of the fluorescence of 2AP in DNA requires a model of the electronic structure

Supercritical Fluids: Their Properties and Applications

December 1, 1998
Author(s)
Johanna Levelt Sengers
This introductory chapter is intended to acquaint the reader with the unusual properties of supercritical fluids, and with the ways these properties are exploited for a variety of applications in the chemical process industry. The presentation is closely
