Synthesis Of Rhenium And Manganese Pyridazoal Complexes, Jesse Evans

Masters Theses & Specialist Projects

Pyridazines are a heterocyclic aromatic compound containing a characteristic N-N bond that are utilized in many fields, including medicine and electronics. It is this latter field that Dr. Snyder's research group is focused upon. Organometallic compounds are a better conducting material than the current inorganic compounds used in electronics due to better conductance of electricity, lower production cost, and the ability to be formed into thin films. With this in mind, Dr. Snyder's research group has set out to synthesize organometallic compounds for this purpose. Following procedures set forth by Snyder etc, and altered to form an off-metal route, we …

Determining Planck's Constant Using Leds, Zechariah Thurman

Zechariah Thurman

In this paper a value for Planck's constant is measured. The value found with this experiment is within two sigma of the accepted value, this constitutes reasonable agreement with theory for the purposes of this experiment.

Analysis Of Modulation And Voltage Balancing Strategies For Modular Multilevel Converters, Ryan Blackmon

Theses and Dissertations

Modular multilevel converters are an emerging voltage source converter topology suitable for many applications. The increased utilization of HVDC power transmission solutions has resulted in modular multilevel converters becoming a more common converter type. Other applications include interfacing renewable energy power sources to the grid and motor drives. Modular multilevel converters are beneficial for medium voltage motor drives because the properties of this converter topology, such as low distortion, allow for an efficient motor drive design.

Modular multilevel converters are designed where instead of using 6 IGBTs as in a conventional voltage source converter, numerous low-rated IGBTs are used to …
