Hydrogen storage in pressed nanophase diamond powder
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The nanophase diamond has been studied as an alternative for solid hydrogen storage, first by the affinity of carbon and hydrogen, and second because ...
Dosimetric properties and radiation hardness of the storage phosphor europium doped potassium chloride for radiation therapy dosimetry
(University of Missouri--Columbia, 2011)
Multidimensional reusable dosimeters are extremely important for characterizing the complex dose distributions associated with modern radiation therapy techniques, such as intensity modulated radiation therapy (IMRT). In ...
Preparation of quantum fingerprint-ready metal-gallium arsenide interfaces for molecular characterization
(University of Missouri--Columbia, 2014)
Quantum Fingerprint� (Charge Based Transient Level Spectroscopy Analysis) trace chemical detectors are desirable due to their high sensitivity, high selectivity, rapid acquisition and response rates, and robustness. These ...
Developing a non-destructive evaluation technique using resonance ultrasound spectroscopy for fission based target
(University of Missouri--Columbia, 2015)
*The purpose of this thesis is to study Resonance Ultrasound Spectroscopy(RUS) and it's potential to evaluate the change in interfacial thermal resistance due to irradiation. Resonant Ultrasound Spectroscopy is conventionally ...
Aerosol evolution : explorations in DSMC and sectional techniques
(University of Missouri--Columbia, 2015)
Understanding and improved modeling of aerosol evolution in nuclear reactor accidents is important in estimations of the nuclear source term as it is greatly affected by the formation and presence of aerosols in the reactor ...
Synthesis and evaluation of radioactive gold nanoparticles for cancer treatment and imaging
(University of Missouri--Columbia, 2015)
This research study explores an appropriate method for production of radioactive gold nanoparticles that may be more appropriate for treating cancer. The first protocol includes using a nontoxic and antitumor phytochemical ...
Knowledge-based radiotherapy treatment planning
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Knowledge-based planning (KBP) has become a prominent area of research in radiation oncology in the last five years. The development of KBP aims to ...
Deposition of aerosols in cylindrical tubes and in human lung airways
(University of Missouri--Columbia, 2010)
Aerosol transport and deposition is of interest in many industrial and medical applications. This research is focused on two specific topics: deposition of aerosols in cylindrical tubes with emphasis on thermophoresis and ...
Design and testing of optimal personal protective equipment for high energy radiation on earth and beyond
(University of Missouri--Columbia, 2016)
This study incorporates an experimental and an associated modeling investigation of human protective shielding methodologies for two extreme environments: first responders or military personnel in the case of nuclear or ...
Measurements of fission product sorption on graphite
(University of Missouri--Columbia, 2017)
Nuclear source estimations for high and very high gas temperature reactors (VHTRs) require data for fission product (FP) adsorption on graphite at high temperatures. The adsorption and vapor pressures of silver on nuclear ...
3D imaging for brachytherapy patient and mold applicator positioning verification
(University of Missouri--Columbia, 2017)
We developed a stereo vision method for 3D imaging of HDR brachytherapy skin cancer applicator positioning and tracking with respect to patients' anatomical features. The setup consists of two high-resolution scientific ...
Photon intermediate direct energy conversion using a Sr-90 beta source
(University of Missouri--Columbia, 2012)
This thesis covers an examination of a need for a compact, long lived power source and a proof of concept for one such design. To begin, tests were done dealing with photovoltaics and their lifetime while undergoing radiation ...
Solutions of some transport problems in molecular and phonon transport
(University of Missouri--Columbia, 2012)
Nuclear reactor fuel undergoes vast changes during its lifetime. The fuel generates heat energy while simultaneously suffering neutron bombardments and swelling/rupture due to fission product/gas migration, aggregation and ...
Modification of materials for high oxidation resistance
(University of Missouri--Columbia, 2012)
As a result of high oil prices and the increase effects of greenhouse gases due to the combustion of fossil fuels is necessary to find other sources of energy. Hydrogen has the potential to replace part of the fossil fuel ...
Measurement of coagulating silver and carbon aerosols using a tandem differential mobility analyzer
(University of Missouri--Columbia, 2013)
One of the unresolved technical issues associated with the high temperature gas-cooled reactor (HTGR) is the production of carbonaceous dust (e.g. by abrasion, corrosion, radiation damage, gas-to-particle conversion) and ...
Modeling and analysis of a portable, solid-state neutron detection system for spectroscopic applications
(University of Missouri--Columbia, 2012)
This paper discusses a new neutron detection system that allows local volumetric identification of fast neutron thermalization in the context of forming a solid state Bonner-like neutron spectrometer. The resulting departure ...
