This thesis reports the reactivity of the trithiolato Ru complex PPN[Ru(DPPBT)3] (DPPBT = 2-diphenylphosphinobenzenethiolate) (1a) with alkenes upon oxidation. Complex 1a in acetonitrile shows two redox events at -345 mV and +455 mV in the square...
Cerium dioxide or ceria, CeO2, has been widely used in industry as catalyst for automotive exhaust controls, chemical mechanical polishing (CMP) slurries, and high temperature fuel cells because of its unique metal oxide properties. This well-known...
This thesis reports the reactivity of the rhenium-thiolate complex, tris(2-diphenylphosphinobenzenethiolato)rhenium(III), [Re(DPPBT) 3 ] ( 1 ) and its oxidized derivatives with ethylene. The reactivity has been studied by electrochemical,...
III-nitrides (InN, GaN, AlN) are some of the most promising materials for making blue light emitting diodes (LED), blue laser diodes (LD) and high power, high temperature field effect transistors (FET). Current techniques produce GaN films with...
Long-term exposure to harmful carcinogens like benzo[a]pyrene (BaP) are linked to lung cancer. Benzo[a]pyrene diol epoxide (BPDE), the ultimate carcinogen produced by BaP bioactivation, is believed to play an important role in lung carcinogenesis....
Dielectrophoresis (DEP) is an electrokinetic force capable of attracting or repelling neutrally charged particles due to a non-uniform electric field [1, 2]. Positive dielectrophoresis attracts particles in the region of the highest electric field...
Rapid Electrokinetic Patterning (REP) is a relatively new method for collecting and manipulating micrometer-scale particles at an electrode surface. REP is an AC electrokinetic technique that uses induced fluid motion to capture and manipulate...
The thesis focuses on improving the flowrate of the Knudsen gas pump. The Knudsen pump uses thermal transpiration as the driving mechanism to pump gas. It is a motionless gas pump as the pump does not require any moving actuators for pumping. The...
This dissertation deals with various imidazole compounds with emphasis on hydrogen bond interactions and weaker intermolecular forces. New amide functionalized polyimidazole metal binding pockets are able to form intramolecular six-membered...
In this thesis self-assembled growth of Ag2Ga nano-needles on batch fabricated
micro-grippers are reported. The room temperature growth of Ag2Ga nano-needles have
been recently developed as stylus for Atomic Force Microscopy (AFM). Integration...
In July 1995, National Science Foundation Award # 9551869 funded the development of a new inter-disciplinary microfabrication course under the primary leadership of Dr. Kevin Walsh at the University of Louisville. Along with this award, the...
In the present study, we report the synthesis of thermally stable mesoporous gallium oxide and novel gallium-niobium mixed oxides employing Evaporation Induced Self-Assembly (EISA), Self-Assembly Hydrothermal-Assisted (SAHA) and Self-Assembly...
Nanomaterials have many intriguing applications in biology and medicine. Unique properties such as enhanced electrical properties, increased chemical reactivity and resistance to degradation, novel optical properties and comparable size to that of...
