Using a membrane reactor for the sulfur-sulfur thermochemical water-splitting cycle

Creator:: Knapp, Nathan Michael
Abstract:: The hydrogen economy is a possible component of an energy future based on use of alternative and renewable energy sources, deemed desirable from the general consensus of the worldwide community that we do not want to further exacerbate the climate problems that we have introduced over the last two centuries...

Study of graphite-polyurethane composite thin film electrodes for their use in electrochemical antifouling systems

Creator:: Delaney, Matthew A.
Abstract:: Prevention of marine biofouling is vital to the survivability and performance of ships, buoys, and wave energy devices. Coatings that contain metal biocides are currently used to prevent marine biofouling. These coatings have a limited lifetime and are under environmental scrutiny. As a result, it is necessary to research and...

Synthesis and characterization of zero valent iron nanoparticles

Creator:: Coussens, Nathaniel J.
Abstract:: Synthetic methods for the preparation of magnetic nanocomposites with improved high frequency (into the GHz range) performance over conventional magnetic materials were examined. The most successful work involved synthesis of nanocrystalline zero valent iron particles (nc-Fe) through a reverse micelle method. Here, aqueous Fe(II) solution micelles formed using cetyl trimethylammonium...

Degradation of N-Nitrosodimethylamine Using Photo-Catalysis and Microreactor Technology : Experimentation and Modeling

Creator:: Omar, Mohamed
Abstract:: The cleanliness of water is a major issue with regards to humanity's continued survival. The chlorination and chloro-amination of water is essential to the creation of microbiologically clean water. However these processes also give rise to oxidative byproducts such as nitrosamines. In particular, due to its high toxicity, N-Nitrosodimethylamine (NDMA)...

Oxidative desulfurization of dibenzothiophene with tert-butyl peroxide in a carbon nanotube supported corona discharge microreactor

Creator:: Caple, Kevin R.
Abstract:: Sulfur content in fuel is an increasingly important environmental concern. A commonly used method for the removal of sulfur bearing species from fuel is through hydrodesulphurization. However, due to the implementation of Ultra-Low Diesel Sulfur (ULDS), deeper desulphurization techniques must be explored. In this study, a single phase oxidative desulphurization...

Influence of processing parameters on diffusion of divalent nickel in wet silica sol-gel monoliths

Creator:: Dickson, David J.
Abstract:: The diffusion of divalent nickel (Ni²⁺) from wet silica gels was investigated. Silica gel is gaining interest as an encapsulation matrix for biological components. The transport of biologically relevant species within the gel is determined by the structural characteristics of the gel, which are in turn governed by synthesis parameters....

Oxidation of hydrocarbon in a carbon nanotube supported corona discharge in micoreactor : oxidation of ethylene

Creator:: Alanazi, Yousef M.
Abstract:: Population growth driven sustainability issues, including the food resource issue, are pressing problems in need of attention. The goal of the present thesis is to examine the ability of an electric non-thermal plasma based microreactor to destroy ethylene, a known plant hormone responsible for losses in the range of 20%...

Rapid bidirectional power flow of supercapacitor bank energy storage through grid-tied inverters for improved renewables integration

Creator:: Bostrom, Arne
Abstract:: The variable output of renewables such as wind and solar causes fluctuations of power flow that can adversely affect power system operation, especially at high levels of penetration. The coordination of multiple energy storage solutions can mitigate integration challenges by providing a buffer from variable renewables. This thesis presents the...

Spatio – temporal temperature variations during droplet impingement evaporation : effects of nanofluid and nano-structured surface

Creator:: Graber, Christof
Abstract:: Droplet and spray impingement cooling are typically used in high heat flux thermal management. In this thesis, droplet impingement and evaporation heat transfer characteristics are determined from measured spatially- and temporally- varying fluid and surface temperatures. Unique to this study is the documentation of the effects of using a nanofluid...

Oxidative desulfurization of dibenzothiophene with tert-butyl hydro peroxide in a photochemical micro-reactor

Creator:: Hebert, Eilleen M.
Abstract:: Sulfur content in fuels is an increasingly critical environmental issue. Hydrodesulfurization removes sulfur from hydrocarbons; however, further desulfurization is necessary in fuels. New methods are required. In this study, micro-scaled single phase oxidative desulfurization is explored. An ultraviolet light-assisted micro-reactor is introduced for desulfurization of dibenzothiophene. Dibenzothiophene is mixed with...
