  • Transition Metal Oxides for Aqueous Electrochemical Energy Storage

    Creator:
    Jiang, Heng
    Abstract:
    In the 21st century, environmental deterioration is now an indisputable fact. Reliable and economically viable electricity systems based on renewable sources are urgently needed to replace the environmentally detrimental fossil fuels. The feasibility of incorporating renewable-but-intermittent solar and wind energy heavily depends on the development of cost-effective and safe technologies,...

  • Excited state molecular structural evolution and chemical reactivity studied by femtosecond stimulated Raman spectroscopy

    Creator:
    Han, Fangyuan
    Abstract:
    In this dissertation, my research work on excited state dynamics of small organic molecules in solutions is presented. Using femtosecond stimulated Raman spectroscopy (FSRS) as the main experimental tool, the excited state hydrogen-bonding dynamics (ESHBD) of Coumarin 102, a common laser dye molecule, in ethanol solution is examined with <150...

  • Electrochemical Reactions in Aqueous Batteries with Anionic Charge Carriers

    Creator:
    Gallagher, Trenton C.
    Abstract:
    In this dissertation, the primary objective is to discover more sustainable electrode materials and study new reaction mechanisms using aqueous electrolytes. The first study conducted reveals a reversible conversion reaction from copper to Cu2CO3(OH)2. The reaction mechanism uses OH- and CO32- as charge carriers at the cathode. The results open...

  • Development of fragmentation techniques in mass spectrometry for biological applications

    Creator:
    Ji, Hong
    Abstract:
    In this dissertation, I present the work of developing more efficient and economical techniques for fragmenting large bio-molecules, and ultimately making mass spectrometry a more powerful tool in proteomics, DNA sequencing, and other areas of biomolecular analysis. Aiming at lowering the installation and operating cost, and delivering electron capture dissociation...

  • Tracking Excited State Proton Transfer and Inhibition with Ultrafast Raman and Transient Absorption Spectroscopy

    Creator:
    Oscar, Breland G.
    Abstract:
    In this dissertation, excited state proton transfer (ESPT) and its inhibition in solution and protein environments are revealed using both femtosecond transient absorption (fs-TA) spectroscopy and femtosecond stimulated Raman spectroscopy (FSRS). Using a tunable Raman pump to enhance transient vibrational features of the photoacidic chromophore HPTS in methanol and methanol...

    Creator:
    Huang, Yu
    Abstract:
    Chemistry of preparing dense film from solution deposition is explored with several cases in this thesis. Surface dense structure, conversion at melting point, and ion exchange in aqueous solution are the main topics covered here for the thin films of aluminum oxide phosphate and tin dioxide. Thin film density, optical...
