Partial Ionization Cross Sections of Organic Molecules

June 13, 2017
Author(s)
Karl K. Irikura
Partial ionization cross sections are the absolute yields of specific ions from an electron- molecule collision. They are necessary for modeling plasmas and for determining the sensitivity of mass spectrometers, among other applications. One mass

Superconducting Detectors

May 24, 2004
Author(s)
Kent D. Irwin
Superconducting detectors operated at temperatures near absolute zero are bringing about a broad revolution in measurement capabilities in a wide range of fields. Superconducting detectors are used in measurements across the entire electromagnetic spectrum

Crack Growth Threshold in Soda Lime Silicate Glass: Role of Hold-Time

February 1, 2003
Author(s)
J -. Guin, Sheldon M. Wiederhorn
Atomic force microscopy was used to examine the shapes of cracks and residual features left behind on the fracture surface after holding cracks at a stress intensity factor below the fatigue threshold for soda lime silicate glass. After propagating a crack

Distinguishing the Relative Contribution of Fossil Fuel and Biomass Combustion Aerosols Deposited at Summit, Greenland through Isotopic and Molecular Characterization of Insoluble Carbon

September 1, 2002
Author(s)
J F. Slater, Lloyd A. Currie, J E. Dibb, Bruce A. Benner Jr
Although the earth's polar regions are isolated from most industrial activity, combustion-generated particles from both fossil fuel and biomass burning impact the regions. Most efforts aimed at quantifying the input of combustion aerosols at Summit
