Spectroscopic and mechanistic investigation of the enzyme mercaptopropionic acid dioxygenase (MDO), the role of the conserved outer-sphere 'catalytic triad' in directing promiscuous substrate-specificity
(2018-05-16)Mercaptopropionate dioxygenase (MDO) from Aztobacter Vinelandii is a non-heme mononuclear iron enzyme that catalyzes the oxygen dependent conversion of 3-mercaptopropionic acid (3mpa) to produce 3-sulfinopropinioic acid ... -
Stimuli-Responsive Peptide Self-Assembly for Therapeutic Delivery
(2022-08-16)Peptide self-assembly offers an effective method to generate supramolecular nanomaterials with much higher stability than traditional monomeric peptides. The materials exhibit well-organized hierarchical structures and ... -
Strategies for enhancing chromatographic efficiencies in chiral and achiral supercritical and liquid chromatography
(2020-09-01)The fundamental aim of chromatography has been to achieve baseline separation between the components of a mixture in the shortest possible time. Recently there has been a shift in the chromatographic focus of enantiomeric ... -
STRUCTURE AND PROPERTY CALCULATIONS OF AMORPHOUS CERAMICS AND GLASSES USING DENSITY FUNCTIONAL THEORY CALCULATIONS AND EMPIRICAL POTENTIAL MOLECULAR DYNAMIC SIMULATIONS
The work in this thesis involves modeling amorphous ceramics and glasses using the tools of DFT and classical MD. Systems investigated include: metal-silicate glasses (in particular HfO2- SiO2), composite coatings (comprising ... -
Structure Modeling and Property Calculations of Amorphous Materials
(2019-05-16)The demand in discovery of novel materials for a seemingly infinite list of applications is growing year by year. Even though it’s not uncommon to find the application for the material after its discovery upon experimentally ... -
Studies in Liquid and Ion Chromatography
(2017-11-30)Height- and area-based quantitation approaches reduce two-dimensional data to a single value. For a calibration set, there is a single height- or area-based quantitation equation. We introduce a new quantitation method; a ... -
