  • Zero kinetic energy photoelectron spectroscopy of polycyclic aromatic hydrocarbons

    Creator:
    Zhang, Jie
    Abstract:
    In this dissertation, I present electronic spectra of a few polycyclic aromatic hydrocarbons (PAHs): tetracene, pentacene, pyrene, benzo[g,h,i]perylene and benzo[a]pyrene using resonantly enhanced multiphoton ionization (REMPI) and zero kinetic energy (ZEKE) photoelectron spectroscopy. The work of tetracene and pentacene also combine a laser desorption source with a ZEKE spectrometer, demonstrating...

  • Electron Diffraction of Neutral and Cationic Clusters Doped into Superfluid Helium Droplets

    Creator:
    Lei, Lei
    Abstract:
    In this dissertation, I describe the experimental investigation of electron diffraction of neutral and ionic clusters doped into superfluid helium droplets. The project is aimed at contributing to the development of an overall approach called ‘serial single molecule electron diffraction imaging (ss-EDI), a potential approach to solve macromolecule structures bypassing...

  • Effects of pH and organic solvents on superfolder green fluorescent protein

    Creator:
    Bravo, Kali J.
    Abstract:
    There is no shortage of challenges in modern science, including the task of obtaining high resolution images of biomolecular structures, such as proteins. Current atomic-resolution structure determination methods include x-ray crystallography and nuclear magnetic resonance (NMR), which present issues like protein crystallization and loss of resolution with increasing size. Dr....

  • Stability of Super Folder Green Fluorescent Protein Under Varying Organic Solvent and Temperature Conditions

    Creator:
    Ho, Lylan
    Abstract:
    Obtaining high-resolution structures of biological macromolecules has become one of the biggest challenges in the scientific world. Dr. Wei Kong’s lab is currently working to overcome the limitations of current structure resolution techniques, such as x-ray crystallography and nuclear magnetic resonance spectroscopy. Kong’s group hopes to develop a new protein...

  • The effect of animal size on the carbonic anhydrase activity of the sea anemone Anthopleura elegantissima

    Creator:
    Tep, Allison P.
    Abstract:
    The sea anemone Anthopleura elegantissima is a model organism for the study of temperate symbiosis. Anthopleura elegantissima can engage in symbiosis with two different algal symbionts: the dinoflagellate Breviolum muscatinei and the chlorophyte Elliptochloris marina. One host enzyme that has been shown to be important in cnidarian-algal symbioses is carbonic...

  • The role of innate immunity in cnidarian-dinoflagellate symbiosis

    Creator:
    Poole, Angela Z.
    Abstract:
    Cnidarians, such as corals and sea anemones serve as hosts to a variety of organisms including symbiotic dinoflagellates, bacteria, virus, and apicomplexans. As corals are vital to the health and productivity of the reef ecosystem it is important to understand how these organisms interact with each component of the holobiont....

  • Polarization spectroscopy and photodissociation studies of nitroaromatic compounds in the gas phase

    Creator:
    Abbott, James E.
    Abstract:
    The central purpose of this dissertation was to explore and expand the use of an uniform electric field for orientation and for subsequent spectroscopic investigation of asymmetric polar molecules in the gas phase. The systems of study were nitrobenzene (NB) and the nitrotoluene (NT) isomers. We were able to quantitatively...

  • Coulomb Explosion in Moderately Intense Nanosecond Laser Fields

    Creator:
    Yao, Yuzhong
    Abstract:
    In this dissertation, I present experimental observations of multiply charged atomic ions (MCAI) generated from interactions of atomic/molecular clusters with moderately intense nanosecond laser pulses. This process is also known as Coulomb explosion (CE) and it has been extensively studied in intense laser fields using ultrashort pulses. Several prevailing theories...

  • Threshold ionization spectroscopy of metal clusters and metal-ligand complexes

    Creator:
    Peng, Xianzhao
    Abstract:
    In this dissertation, we describe a spectroscopic study of metal clusters and metal-ligand complexes using pulsed field ionization zero kinetic energy (PFI-ZEKE) photoelectron spectroscopy and mass analyzed threshold ionization (MATI) spectroscopy. Vibrational resolved spectra of sodium dimer, Na•NH₃, Na•(NH₃)₂ are presented. These spectra provide a direct measurement of the ionization...
