QUANTIFYING THE EMISSIONS OF CARBON DIOXIDE (CO2), CARBON MONOXIDE (CO), AND NITROGEN OXIDES (NOx) FROM HUMAN ACTIVITIES: TOP-DOWN AND BOTTOM-UP APPROACHES
(2021)This dissertation encompasses three projects that quantify the emissions of greenhouse gases and air pollutants from human activities. In the first project, we use the aircraft-based mass balance (MB) approach to quantify ... -
QUANTITATIVE ANALYSIS OF INTACT PROTEINS AND RNAS CARRIED BY IMMUNOSUPPRESSIVE EXOSOMES
(2016)Myeloid-derived suppressor cells (MDSC) are immature myeloid cells that accumulate in the tumor microenvironment of most cancer patients. They are a major obstacle to immunotherapy because they suppress both adaptive and ... -
QUANTITATIVE ANALYSIS OF THE ATMOSPHERIC OXIDATION OF ISOPRENE USING MODELS AND MEASUREMENTS: IMPACTS ON SURFACE OZONE
(2019)The oxidation of isoprene – one of the most abundant volatile organic compounds (VOCs) in our atmosphere – significantly impacts the formation of surface ozone, which is detrimental to public health. Computer models simulate ... -
QUANTITATIVE ASSESSMENT OF BIS(2-ETHYLHEXYL) PHTHALATE IN COMMONLY-CONSUMED FOODS AND ELUCIDATION OF ITS NATURAL COMPONENT IN STILTON CHEESE BY COMPOUND-SPECIFIC CARBON ISOTOPE ANALYSIS
(2013)Bis(2-ethylhexyl) phthalate (DEHP) is classified as a "priority hazardous substance" by the European Union, a probable human carcinogen by the United States Environmental Protection Agency, and is a suspect human endocrine ... -
Quantum mechanical investigation on the vibrational relaxation of HF in collisions with H atoms
(2007-05-10)We investigate the vibrational relaxation of HF(v=2-5) in collisions with H atoms by means of fully-quantum reactive scattering calculations. Our calculations are based on the global ab initio potential energy surface of ... -
Quinone Methide Alkylation of DNA: Understanding Reactivity Through Reversibility, Trapping, and Substituent Effects
(2006-09-11)Alkylation of DNA by a variety of small molecules has been found to be both a cause of cancer and a treatment of the disease. One class of alkylating agent is the quinone methides (QMs). These highly electrophilic molecules ... -
RAPID HEATING AND CHEMICAL SPECIATION CHARACTERIZATION FOR COMBUSTION PERFORMANCE ANALYSIS OF METALLIZED, NANOSCALE THERMITES AND PVDF BOUND SOLID PROPELLANT COMPOSITIONS
(2021)Energetic materials research focuses on performance analysis of cost-effective solid materials which safely, precisely, and efficiently transitions stored chemical potential energy to kinetic energy at a rate throttled ... -
Rapid kinetics study of the nuclease activity of RecBCD enzyme from Escherichia coli
(2006-03-31)RecBCD enzyme from Escherichia coli is involved in homologous recombination and repair of bacterial DNA, and in defending the cell against foreign DNA. This enzyme has multiple functions - it is an ATP-stimulated ssDNA ... -
RAPID Lithography: Photopolymerization Characterization and Initiation Kinetics
(2012)In order to improve upon the resolution of photolithography, a technique that is used to produce features for today's micro and nanodevices, techniques must move beyond e-beam and deep-UV sources. Multiphoton absorption ... -
REACTION MECHANISMS AND INTERFACE CHARACTERISTICS OF ELECTRODE AND ELECTROLYTE MATERIALS FOR MAGNESIUM BATTERIES
(2020)Rechargeable magnesium (Mg) batteries are an emerging electrical energy storage technology proposed as an alternative to current Lithium-ion (Li-ion) batteries. Mg batteries have the potential to provide more energy than ... -
Reactions of Zintl ion Pb9 with Gold Precursor PPh3AuCl
(2006-12-10)Transition metal main group clusters have been studied extensively as models for heterogeneous catalysts and metal surface reactions. In this thesis, reactions of Group 14 Zintl ion cluster Pb94- with the Au precursor ... -
The Redox Chemistry of Dirhodium Carboxamidates: From Fundamental Structures to Catalytic Functions.
