  • Elemental abundances in meteoritic chondrules

    Creator:
    Osborn, Thomas Ward, III
    Abstract:
    High-precision instrumental neutron activation analysis has been used to determine Al, Na, Mn, Sc, Cr, Fe, Co, and Ni in a suite of more than 500 chondrules from 26 distinct meteorites. These meteorite specimens represent the H, L, LL and C chemical classes and most of the petrologic types. In...

  • Sodium and manganese homogeneity in chondritic meteorites

    Creator:
    Osborn, Thomas Ward, III.
    Abstract:
    Four to six one-gram specimens separated by a distance of several inches were obtained from each of 23 large chondritic meteorites (approximately 1 kg each) representing the olivine bronzite (H5), olivine hypersthene (L6) and enstatite (E5) classifications. Each specimen was analyzed for Na and Mn via instrumental neutron activation analysis...

  • Hydrogen abstraction from substituted t-butylbenzenes

    Creator:
    Harvey, Robert Louis
    Abstract:
    A study of the relative rates of the alkyl hydrogen abstraction from a series of meta and para substituted t-butylbenzenes by the chlorine atom at 70°C has been carried out. Application of the Hammett equation yielded a ρ value of -0.44 for the para compounds. Possible explanations for the non-linearity...

  • The photodecomposition of t-butyl bicyclo [7.1.0] decane-2-percarboxylate

    Creator:
    McRitchie, Donna Louise
    Abstract:
    This paper describes the synthesis of t-butyl bicyclo[7.1.0] decane-2-percarboxylate and its photolytic decomposition. The title compound was found to undergo simple homolytic cleavage when exposed to light of 2537 A; producing the cyclodecyl radical, carbon dioxide, and t-butoxy radical. The largest percentage of products arose from an intimate radical pair...

  • Comprehensive, Low-Cost Wicking Microfluidic Analytical Devices for Clinical Diagnostics and Environmental Analysis

    Creator:
    Bandara, Gayan C.
    Abstract:
    Analytical techniques are utilized in a wide variety of applications. Traditionally, analytical measurements are achieved by trained personnel in a laboratory setting using expensive scientific instruments, which limits their applicability in resource-limited areas and point-of-care applications. Therefore, the concept of enabling these laboratory-based qualitative and quantitative assays in microfluidic device...

  • Electrochemical studies of liquid chlorocuprates(I)

    Creator:
    Silkey, James R.
    Abstract:
    This research emphasized fundamental physical and electrochemical studies of systems based on the room temperature fused salt, triethyl-ammonium dichlorocuprate(I). Such systems, which must be maintained under a protective atmosphere, were also used in some preliminary battery studies. Spectra of dark green solutions of copper (II) chloride in triethylammonium dichlorocuprate(I) obey...

    Creator:
    Heist, Christopher A.
    Abstract:
    The overall concept of reducing laboratory operations to a scale that fits on a single microfluidic chip has been an attractive area of research over the last several decades. Despite a surge in research, few commercial success stories have been written. Lab-on-a-chip technologies have the capability to be cost effective...
