My dissertation researches are on the field of fuel cell materials and fuel cell modeling. During my dissertation research, I authored two US patent applications and have developed several innovative approaches to new fuel cell materials...
Since their discovery by Iijima in 1991 carbon nanotubes have been used in many novel applications of nanotechnology. Carbon nanotubes thin films in particular can be used to create, among others, anti-reflection coatings or stretch...
Locating ground faults in ungrounded systems is inherently difficult because such faults do not provide considerable fault currents for tracing the fault location and the locating process has to be done during system operation. In this...
This dissertation is made of two parts. Part I, chapter 1 to chapter 7, is 2-D square rod-in-air photonic crystal optical switch; Part II, chapter 8 to chapter 12, is design of fast laser shutter. Photonic crystal is a kind of materials...
The energy density of conventional electric double-layer capacitors is about 6-7 Wh/kg and due to the limited specific capacitance and cell voltage, and a large amount of electrolyte which is required to build a layer of charge of the...
Thesis starts with the introduction and literature review of energy storage and conversion devices, which lay the background for motivation and purpose of this research. The fundamental background behind this work was laid by Zheng et al...
In this thesis a practical approach for characterizing the common mode behavior of the power electronic devices (PED) on board a next generation All-Electric ship (AES) power system is proposed. As the topic of AES design is becoming...
Energy harvesting and alternative renewable energy techniques are currently some of the most sought after research topics for engineers and scientists. Global warming has forced the researchers to abandon the rampant use of coal...
Gas turbine-synchronous generator (GT-SG) systems are the main source of power and propulsion onboard most naval ships. Since this system plays a vital role in accomplishing the ship's mission, a lot of testing is conducted to ensure...
The stochastic nature of ion implantation and diffusion processes induces variations of random doping concentration, which result in the fluctuations of the intrinsic parameters of semiconductor devices. The fluctuations of intrinsic...
LiFePO4 batteries have been in existence since 1997 through the work of Padhi et al and showed promise early on due to its material abundance, low cost, low environmental impact, high temperature tolerance and theoretical capacity of...
Thus far, capacity fade has been ascribed to various mechanisms that include (i) the dissolution of highly resistive surface films on the electrode surface which result from side reactions; (ii) loss in active electrode materials; (iii)...
Waveform distortions in power systems are inherently time-varying due to continuous changes in system configurations, load types, and load levels. The time-varying nature of waveform distortions requires a real time tool to process that...
A 3.5MVA High Temperature Superconductor (HTS) transformer has been in design at FAMU-FSU College of Engineering since 2002. The coils of the HTS transformer use stainless steel sheathed Bi2223 HTS wire. In order to make insulation...
The main challenge in the solar cell industry is making the solar cells more cost effective. Mono and poly-crystalline Si, CdTe, CIGS, Quantum dot, Organic and Dye-sensitized solar cell technologies do not produce high efficiencies. A...
