This thesis experimentally determines the feasibility to creating C4 to C10 hydrocarbons from CO2, CO, H2, H2O and CH4. This is done in two steps, the initial step is the formation of ethylene through DC electrical glow discharge at ambient pressure while the second step is through temperature pulse controlled...
Thermochemical water splitting cycles have been conceptualized and researched for over half a century, yet to this day none are commercially viable. The heavily studied Sulfur-Iodine cycle has been stalled in the early development stage due to a difficult HI-H₂O separation step and material compatibility issues. In an effort to...
MOTIVATION: Estimation of bacterial community composition from
a high-throughput sequenced sample is an important task in
metagenomics applications. Since the sample sequence data
typically harbors reads of variable lengths and different levels of
biological and technical noise, accurate statistical analysis of such
data is challenging. Currently popular estimation methods are...
Over the past century, life expectancy in the United States has dramatically increased leading to an increasingly aging population with people reaching, and spending more years in ‘old age’. While this unprecedented shift in population demographics represents great strides for humanity, it is not without cost. One consequence of longer...
Dry reforming of methane to syngas using CO2 was performed in a solar-driven milli-scale reactor, which converts solar energy to chemical energy. The process aims to upgrade the energy content of the feed stream using sustainable energy. The effect of mean residence time, temperature and CO2:CH4 ratio on conversion and...
A present abundance of biomass and a decreasing supply of petroleum signal the need for efficient pathways from renewable feedstocks to high value chemicals. One such class of chemicals is oleofurans, molecules comprised of a furan ring and carbon chain which can be used to make powerful hard water surfactants....
The enclosed thesis presents an algorithm, programmed
in FORTRAN IV, which generates the radii for
the objective of an astronomical refracting telescope.
The results are analyzed by the Trigonometric Ray
Trace, and found to have tolerable amounts of spherical
aberration, chromatic aberration and coma.
The objective of this thesis was to investigate the use of the Jacobian Free Newton Krylov Method (JFNK) with physics based preconditioning for solving coupled radiative transport and material energy balance. Modeling of these physics is important in inertial confinement fusion and other high energy density systems. In this thesis,...
Riparian zone conservation is vital as species’ ability to adapt to a changing climate and pressure from land use is constantly tested. The unique microclimates of riparian zones offer cooler temperatures and resourceful habitats for aquatic and terrestrial organisms. This is essential during seasonal ceased flow regimes when water availability...
