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 ...
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 ...
Direct simulation Monte Carlo exploration of charge effects on aerosol evolution
(University of Missouri--Columbia, 2012)
Aerosols are potentially generated both during normal operations in a gas cooled Generation IV nuclear reactor and in all nuclear reactors during accident scenarios. These aerosols can become charged due to aerosol generation ...
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 ...
Volumetric modulated arc therapy (VMAT) : advanced delivery techniques for static and moving targets
(University of Missouri--Columbia, 2012)
Volumetric Modulated Arc Therapy (VMAT) is a rotational radiation therapy which has been used to treat various cancer sites. The continuous delivery of a specific treatment plan for arc therapy can be achieved with multiple ...
Quantification of absorbed doses from radioactive gold nanoparticles and chromium 51 seed implants
(University of Missouri--Columbia, 2012)
In the ever ending search to seek better options of treatments in radiation therapy, few novel approaches are presented in this thesis. The work presented is in 2 folds. Potentially both can be applied in radiation dose ...
Development of instrumentation and techniques for preclinical image guided microirradiation
(University of Missouri--Columbia, 2012)
Radiation therapy accounts for more than half of cancer treatments in the US, and in order to provide the most effective treatment to patients, new developments are implemented each year. Before a novel radiation therapy ...
Maximum hypothetical accident analysis for HEU to LEU fuel conversion at the University of Missouri Research Reactor
(University of Missouri--Columbia, 2014)
Surface characterization and measurements of adhesion force between graphite clustered particles and Hastelloy X surface using an atomic force microscope
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This work reports preliminary results on the determination of the adhesion forces between a graphite cluster probe and Hastelloy X samples having ...
Generation of graphite particles by rotational/spinning abrasion and their characterization
(University of Missouri--Columbia, 2011)
Graphite particle generation by inter-pebble abrasion and by abrasion of pebbles with the containment vessel during operation of a Pebble Bed Reactor (PBR) is an issue of interest in the safety analysis of this class of ...
Process management and scheduing [sic] in radiation therapy
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Management of complex, advanced technology, high cost, and high risk operations requires reliance on systems engineering principles. This approach has ...
Transport of helium and fission product gases in porous/fractured geometry
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Measuring and quantifying the transport of helium and fission products in reactor materials is a critical element in the future success of Very High ...
Neutron exposure from electrom linear accelerators and a proton accelerator : measurements and simulations
(University of Missouri--Columbia, 2011)
The risk of developing radiation induced secondary cancers in patients undergoing external beam radiotherapy is a concern; particularly from secondary neutrons generated during delivery of high energy photon and proton ...
Modeling and maximum theoretical efficiencies of linearly graded alphavoltaic and betavoltaltaic cells
(University of Missouri--Columbia, 2011)
This thesis presents a study on the optimization of the energy deposited by alpha and beta particles in the depletion region of a silicon carbide as alphavoltaic and betavoltaic cells using Monte Carlo codes. Two Monte ...
Chemical sensor using single crystal diamond plates interrogated with charge-based deep-level transient spectroscopy based on the Quantum Fingerprint[TM] model : instrumentation and methodology
(University of Missouri--Columbia, 2011)
In recent years, diamond has received a great deal of interest as a potential chemical sensor material due to its mechanical robustness, and its capacity to modify its electrical characteristics according to surface ...
