  • A new technique for high performance tandem time-of-flight mass spectrometry

    Creator:
    Katz, Daniel Louis
    Abstract:
    The main result of this written dissertation is a mathematical solution to the problem of multiplex recording for high performance tandem time-of-flight mass spectrometry. The prescription is to use a time-lag accelerator in the second stage to match the ion optical properties of the decay fragments to the requirements of...

  • Time-of-flight direct recoil spectrometry : application to liquid surfaces and steps toward quantification

    Creator:
    Tassotto, Michael
    Abstract:
    Liquid surfaces are very abundant in nature. Despite the importance of the liquid interface in general, experimental molecular-level data was almost completely lacking prior to the last decade and a half. The intent of this work is to provide a means by which experimental data on the composition of liquid...

  • First principles studies of optical, electronic and mechanical properties of organic molecules and solids

    Creator:
    Barras, Faye Lyn
    Abstract:
    This thesis presents the results of quantum-mechanical first principles calculations of optical, electronic and mechanical properties of organic molecules and solids, which have diverse potential applications such as photovoltaics, flexible electronics, and mechanical catalysts with applications in force sensors and self-healing materials. The electronic and optoelectronic properties of organic thin...
