Intermetallic microlamination for high-temperature microreactors

Creator:: Dewey, Tyler
Abstract:: Chemical microreactors offer opportunities for portable power generation, on-site waste remediation and point-of-use chemical synthesis. Much of the existing development of microreactor devices involves silicon-based microfabrication techniques. It is recognized that new refractory materials are important to realizing high-temperature microreactors. Requirements of these materials include high-temperature resistance, chemical inertness and...

Desulfurization of thiophene and dibenzothiophene with hydrogen peroxide in a photochemical microreactor

Creator:: Al-Raie, Ali H.
Abstract:: Sulfur content of fuels and desulfurization of fuels is becoming an important environmental restriction and regulatory issue. In this study new technology for the desulfurization of fuels is considered. Micro scale reactors are introduced for desulfurization of thiophene and dibenzothiophene. Thiophene and dibenzothiophene are mixed with hexane at concentration, C₀...

Continuous flow microreactor for chemical bath deposition : a novel approach to the deposition of polycrystalline semiconductor thin films

Creator:: Mugdur, Prakash
Abstract:: Over the years, chemical bath deposition (CBD) is being widely used in the fabrication of Cu (In, Ga) Se₂ and CdTe based solar cells and photovoltaics. Many chalcogenides have been successfully deposited by this technique and it has received a great deal of attention owing to its low temperature and...

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...

Flow characterization of multiple-tube reactors for synthesis of nano-sized silicon nitride powder via silicon monoxide ammonolysis

Creator:: Vas-Umnuay, Paravee
Abstract:: Concentrically arranged multiple-tube reactors with different dimensions were built for synthesizing nano-sized silicon nitride powder via the ammonolysis of SiO vapor. The reaction was operated at temperatures ranging from 1350 to 1400°C and pressure slightly above atmospheric pressure. Silicon monoxide (SiO) vapor was generated by charging argon gas through a...

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...

Synthesis of titanium dioxide nanorods using a continuous flow microreactor

Creator:: Yen, Wei-Liang
Abstract:: The primary goal of this thesis is to synthesize titanium dioxide nanorods using a continuous flow microreactor. Titania powder, one of the most important particulate materials is used for many purposes owing to its excellent optical properties of a high refractive index leading to high hiding power and whiteness of...

Performance of a thermally activated cooling system and design of a microchannel heat recovery unit

Creator:: Seward, Ryan
Abstract:: The performance of a combined vapor-compression cycle/ORC is evaluated using waste-heat from a diesel generator. A flat plate microchannel heat exchanger is employed to provide energy exchange between the diesel exhaust stream and an oil loop, which provides energy to a boiler. This study finds an increased diesel duty corresponds...

A microchannel-based thermal management system for hydrogen storage adsorbent beds

Creator:: Steigleder, Leif J.
Abstract:: Hydrogen has been shown to be a promising replacement for fossil fuels for use in light duty vehicles because it is a clean, renewable and plentiful resource with a high gravimetric energy density. However, in order to obtain an acceptable volumetric energy density, densification of the hydrogen is required. Adsorptive...

Synthesis and evaluation of PEO-coated materials for microchannel-based hemodialysis

Creator:: Heintz, Keely
Abstract:: The marked increase in surface-to-volume ratio associated with microscale devices for hemodialysis leads to problems with hemocompatibility and blood flow distribution that are more challenging to manage than those encountered at the conventional scale. In this work, stable surface modifications with pendant polyethylene oxide (PEO) chains were produced on polycarbonate...
