  • The photochemistry of polychlorobenzenes in micellar media

    Creator:
    Lee, Youn-Sik
    Abstract:
    Photolysis of pentachlorobenzene was carried out in the absence of an electron donor species at 254 nm in cetyltrimethylammonium bromide surfactant solution. The results are consistent with the excited triplet undergoing homolytic cleavage of a C-Cl bond in competition with formation of the excimer, in which the radical anion undergoes...

  • The chemistry of certain tetrahydropyrimidines

    Creator:
    Anderson, Donna Lee
    Abstract:
    Since many 1, 4, 5, 6-tetrahydropyrimidines have become available and commercially useful in recent years, a study of the chemistry of certain of these compounds has been undertaken. 2-Hydroxy- and 2-mercapto-1, 4, 5, 6-tetrahydropyrimidine have been synthesized by the condensation of urea and thiourea, respectively, with 1, 3-propanediamine, with yields...

  • Gene Expression, Structure Elucidation, and Bioactivity of Aspergillus Natural Products

    Creator:
    Neuhaus, George F.
    Abstract:
    The study of natural products (NPs) and their application has shaped humanity. Starting with the idea of using plants as medicine, it has now grown into the science of purifying and identifying organic molecules from nature to study their inherent biological activities. Understanding the molecular structures of NPs is the...

  • Using Computational and Statistical Methods as an Aid to Study Environmentally Relevant Organic Molecules

    Creator:
    Dorn, Shelby E.
    Abstract:
    In this report, three studies are presented that utilize computations to predict transformations, identities, and properties of environmental organic molecules. Each study shows how computations can lead to models of chemical behavior. The importance of this research is rooted in the need for understanding how human behavior and health intersect...

  • Total kinetic energy release in the fast neutron induced fission of actinide nuclei

    Creator:
    Loveland, Walter
    Abstract:
    The total kinetic energy release and fission mass distributions for the fast neutron (En = 3–100 MeV) induced fission of 232Th, 233U, 235U, 237Np, 239Pu, 240Pu, and 242Pu have been measured using the LANSCE facility. The neutron energies were deduced from time-of- flight measurements. The fission fragments were detected using...

  • Refractory Amorphous Metal Thin Films

    Creator:
    Olsen, Kristopher R.
    Abstract:
    Amorphous metal thin films lack the grain boundaries and dislocations present in crystalline metal films. As a result, amorphous metal films can be more mechanically robust, atomically smooth, and more resistant to chemical attack than crystalline metals. However, amorphous metals are meta-stable and subject to crystallization upon heating, thus limiting...

  • Gold Nanostars: Spectroscopic and Physical Properties

    Creator:
    Zhou, Lixia
    Abstract:
    Tethering fluorophores on metal nanoparticles for metal enhanced fluorescence (MEF) has attracted a lot of attention from scientists interested in fluorescence based approaches. MEF has many benefits in fluorescence related techniques, because the analytical signal increases and enables potentially lower detection limits or better sensitivity. Many types of nanoparticles have...

  • Gene Activation Strategies in Filamentous Fungi for Natural Products Discovery

    Creator:
    Adpressa, Donovon A.
    Abstract:
    Fungi have long been a prolific source of clinically approved drugs. The antibiotic penicillin, the cholesterol lowering statins, and the immunosuppressant cyclosporine have changed the treatment of human diseases in the last century. Recently, genome analysis of filamentous fungi has revealed that the biosynthetic potential for natural product expression is...
