Fission product diffusion in ig-110 graphite
(University of Missouri--Columbia, 2022)
The threat of global climate change and resultant disasters has never been higher. The promises made by many countries of carbon neutrality by 2050 will be impossible to achieve without nuclear technology. Global public support for nuclear energy...
Crossed-beam chemical reaction dynamics probed with universal and state resolved ion imaging
(University of Missouri--Columbia, 2018)
The main goal of chemical reaction dynamics is to unravel the intimate motions of individual atoms during a chemical transformation. This information must generally be inferred from indirect macroscopic measurement. Very important information...
Isotope harvesting from the beam dump cooling loop at the facility for rare isotope beams (FRIB)
(University of Missouri--Columbia, 2018)
Isotope harvesting from the beam dump cooling loop of the Facility for Rare Isotope Beams (FRIB) offers usable quantities of many isotopes unavailable anywhere else in the world. Many of these co-produced isotopes are of ...
Inactivation of protein tyrosine phosphatases by endogenous and dietary agents
(University of Missouri--Columbia, 2009)
disrupting signaling pathways inside cells. It is possible that these small molecules are exerting their widely reported biological effect by the modification of protein tyrosine phosphatase activity. This information is critical to our understanding...
Development of food adulteration detection methods utilizing NMR spectroscopy
(University of Missouri--Columbia, 2022)
Food adulteration is the act of diluting foodstuffs with undeclared fillers or outright substitution with other materials. While this practice has occurred since the dawn of recorded history it has remained difficult to ...
Coulomb explosions dynamics
(University of Missouri--Columbia, 2022)
in real time. Extracting structural information from CEI requires imaging of multiple fragments at each experimental cycle which allows us to obtain their relative velocity distribution. In this work, we successfully coupled a three-dimensional multi...
Insights into atomic orbital polarization in polyatomic dissociation from DC slide velocity map imaging
(University of Missouri--Columbia, 2019)
, it maps the recoil velocity distribution of the state selected product onto a position sensitive detector plane and energy and the angular distributions information are extracted by reconstruction of the experimentally observed images. The main objective...
Measurement of radionuclides in biological tissues from occupationally exposed individuals
(University of Missouri--Columbia, 2022)
-documented actinide exposures needs to be studied. In addition to measurement of actinide concentrations, the isotope ratios 240Pu/239Pu, 235U/238U, and 236U/238U provide information that is useful for discriminating between actinide sources and americium measurement...
Evaluation for ammonium bifluoride dissolution for application to post-detonation nuclear forensics and rare Earth element extraction
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] If a nuclear device were to be used in an act of terrorism, prompt nuclear forensic analysis of the post-detonation debris is crucial in order to ...
Spectroscopic investigations of acrylodan dye interactions with poly(amidoamine) and poly(propyleneimine) dendrimers
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The novel molecular architecture of dendrimers facilitates use in many applications. Using the solvatochromic probe phenol blue, the first direct ...
Novel techniques for cold/ultracold molecular collisions
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This thesis presents the successful implementation of a slice velocity map imaging apparatus capable of performing molecular beam scattering experiments at collision energies...
Novel chemical mechanisms of DNA damage by natural products
(University of Missouri--Columbia, 2007)
-not alkylate singlestrand DNA or nucleoside and needs specific non-covalent interaction with the DNA duplex for alkylation of the N7-deoxyguanosisne residues in DNA. Earlier work done in our laboratory shows that leinamycin is a novel non-classical DNA...
Broadband rotational spectroscopy in Laval flows: applications in astrochemistry and dynamics
(University of Missouri--Columbia, 2022)
This dissertation presents the successful implementation of a Chirped pulse Uniform Flow (CPUF) apparatus capable of conducting experiments at low temperatures to examine photodissociation/reaction dynamics and kinetics studies relevant...
Probing supramolecular assemblies via fluorescent reporter molecules
(University of Missouri--Columbia, 2007)
Supramolecular, self-assembled nanocapsules have shown the capability to encapsulate organic guests. Since most of the work was done previously in the solid state, the novelty of this research was its focus on probing ...
Monte Carlo neutronic simulations for a new approach to parametric INAA and Mo-99 production feasibility at MURR
(University of Missouri--Columbia, 2009)
A novel approach to parametric instrumental neutron activation analysis at MURR has been established. In particular, a detailed MCNP5 steady-state model of the MURR core was developed. The model, which was based on the ...
