Bridging the Gap Between Equilibrium Properties and Ultrafast Dynamics with Time-Resolved Spectroscopy of Functional Systems

Creator:: Krueger, Taylor D.
Abstract:: Ultrafast spectroscopy has recently gained momentum as a powerful, noninvasive characterization toolset capable of studying a diverse array of samples with applications in chemistry, physics, biology, engineering, and more. Two popular ultrafast spectroscopic techniques include femtosecond transient absorption (fs-TA) and femtosecond stimulated Raman spectroscopy (FSRS). The latter of these techniques...

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...

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...

Analytical Platform to Study Bacterial Metabolism and their Interactions with Biomaterials using SECM

Creator:: Sheet, Partha S.
Abstract:: The microbial communities play a crucial role in maintaining human health and cause diseases through very complex microbial chemical interactions. Therefore, these microbial communities have drawn much attention to the scientific communities. To elucidate these complex microbial communities and the chemical interactions within it, one or more isolated species of...

Dynamics and Design of Green Fluorescent Protein-Inspired Superphotoacids and Red-Emitting Fluorophores with Transient Absorption and Femtosecond Stimulated Raman Spectroscopy

Creator:: Chen, Cheng
Abstract:: In the past decades, femtosecond stimulated Raman spectroscopy (FSRS) has been gaining tremendous popularity in fundamental sciences stemming from chemistry to biology. It is capable of capturing both equilibrium and non-equilibrium structural information across a broad range of timescales with simultaneously high temporal and spectral resolutions. Femtosecond transient absorption spectroscopy...

Electrochemical Micro-sensors for Probing Bacterial Metabolic Behavior with Scanning Electrochemical Microscopy

Creator:: Jayathilake, Nadeeshani M.
Abstract:: Dental plaque is one of the well-characterized biofilms in the human body. Oral bacterial species play vital roles in maintaining healthy bacterial homeostasis as well as causing oral infections. Many of the oral diseases are caused by opportunistic pathogens, and therefore, the bacterial metabolic activities become important in dictating their...

CoLocalized Excitation Emission Resolution : A CLEER approach for multicolor fluorescence analysis

Creator:: Almlie, C. Kyle
Abstract:: Fluorescence has proven to be a robust and powerful method of analysis in numerous fields: forensics, pharmaceutics, geology, food science, and environmental sciences have all developed a large collection of fluorescence instruments and methods to overcome application-specific challenges. Biological applications saw the same development of a fluorescence toolkit with methods...

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...

Part I: Synthetic Studies Towards Viridin, Halenaquinone, and Obtusanal. Part II: Analysis, Synthesis, and Characterization of Coronene Derivatives.

Creator:: Waldenmaier, Pieter K.
Abstract:: This thesis is separated into three distinct projects. First, synthetic studies towards the furanosteroid viridin shown in part I. Second, synthetic studies towards the diperene obtusanal shown in part II. Third, the analysis, characterization, and synthesis of coronene derivatives towards their application in organic batteries shown in part III. Significant...
