Functionalized Bead Based Microchip for Immunoassay and Virus Immuno-affinity Chromatography
DownloadFall 2014
We demonstrate the functionalization of a highly ordered porous molecular sieving matrix created by colloidal self-assembly (CSA) of 2 micrometer diameter silica particles in microfluidic chips, for highly efficient immuno-capture of viruses. By tuning the particle size, with appropriate surface...

High Resolution Spectroscopy of Chirality Recognition and Solvation of Prototype Chiral Molecular Systems
DownloadFall 2014
The chirality recognition, chirality induction, chirality amplification, chirality synchronization and solvation of prototypic chiral molecular systems were studied using chirped pulse and cavity based Fourier transform microwave spectroscopy with the aid of high level ab initio calculations. The...

In-Situ Spectroscopic Characterization of Operating Polythiophene Nonvolatile Memory Devices
DownloadSpring 2014
Au/P3HT/PEO-EV(ClO4)2/C/Au nonvolatile memory devices were developed based on resistive switch of conducting polymers in the solid state. The P3HT layer was switched using a “write/erase” bias, while internal composition of the device was monitored using in-situ UV-Vis absorbance spectrometer...

Insights into the reactivity of H2CO3 and its derivatives in bulk water, water clusters, and at the air/water interface: Ab initio molecular dynamics and metadynamics studies
DownloadFall 2014
H2CO3 can decompose into CO2 in water either via the water route (H2CO3 ↔ CO2+H2O ) or the hydroxide route (H2CO3 + H2O ↔ CO2+OH−+H3O+). The water route reactions play a fundamental role in the global carbon cycle, and the hydroxide route reactions play an important role in the regulation of...

Fall 2014
This dissertation expands the scope and understanding of the Nazarov electrocyclization and interception of the reactive cyclopentenyl cation intermediate that is formed though a 4π electrocyclization of a pentadienyl cation. An intermolecular process for interrupting the Nazarov is discussed....

Investigating Protein-Carbohydrate Interactions with Hydrogen/Deuterium Exchange Mass Spectrometry (HDX-MS)
DownloadFall 2014
The application of hydrogen/deuterium exchange mass spectrometry (HDX-MS) to investigating protein-carbohydrate interactions is described. Proteins from three bacterial toxins, the B subunit homopentamers of Cholera toxin (CTB5) and Shiga toxin type 1 (Stx1B5) and a fragment of Clostridium...

Liquid Chromatography: Injection Broadening in Ion Chromatography and Retention Properties of a New Hydrophilic Interaction Liquid Chromatography Stationary Phase
DownloadFall 2014
Ion Chromatography (IC) is a powerful technique in the separation and analysis of inorganic ions and small charged organic molecules. Meanwhile, Hydrophilic Interaction Liquid Chromatography (HILIC) enables the separation of polar hydrophilic compounds. Although their retention mechanisms are...
