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...

Dermal wounds, including bed sores, pressure ulcers, and diabetic ulcers have a large impact on American healthcare costing up to $7 billion per year. Adequate pharmaceutical remedies applied at constant rate could prove to increase the healing...
The Knudsen pump works on the principle of thermal transpiration. As a result of requiring a thermal gradient, channel hydraulic diameter smaller than the mean free path of the gas being pumped, and having no moving parts, the Knudsen pump features...
Historically in the area of pediatric heart failure, few options have been available that are specifically designed to provide pediatric circulatory support. Extracorporeal Membrane Oxygenation (ECMO) was the traditional method of choice, providing...
Supervisory Control and Data Acquisition (SCADA) systems are used in almost
all industrial processes including use in the nation's critical infrastructure. The electric,
water, and gas industries are merely a few that rely heavily on the use of...

Cardiovascular disease (CVD) is the leading cause of death in the United States and accounts for nearly 1,372,000 deaths each year. In addition, ~81 million Americans suffer from some form of CVD. Understanding the molecular basis of various...
Most of the structures in submillimeter-scale engineering are created from thin films, making them essentially two-dimensional (2D). Significant work has been done to fabricate 3D structures using self-folding, a deterministic form of...
The purpose of this dissertation was to demonstrate that a new method of direct intracellular energy delivery was effective in maintaining viability of in vitro Human Umbilical Vein Endothelial Cells (HUVECs) when exposed to chemical ischemia for...
Characterization of the optical and electrical properties of organic solar cell materials is of prime importance to organic solar cell design. This thesis describes the use of capacitive photocurrent measurements to study the exciton generation and...
Assessing the functionality of the endothelium can provide insight into the initiation and formation of arterial diseases. One of the most important functions of the endothelial layer is its permeability. The integrity of the cell monolayer and its...
Mixing machinery; Production engineering--Case studies
A processing facility in Trenton, Ky owned by HydroSolutions is in need of modernization in order to increase efficiency in the mixing process, improve the safety of the facility, and give the facility the ability to expand in the future. The main...

Na,K-ATPase is essential for the regulation of cytoplasmic Na+ and K+ levels in lens cells. Insufficient Na,K-ATPase activity is associated with cataract formation. Based on earlier studies in which Src-tyrosine kinase inhibitors were found to...
This thesis is based on experimental work on electrochemically mediated charge transfer effects on Single-walled carbon nanotube bundles. The study of these effects are very important towards understanding the sensitivity of gases on nanostructures...
Circulating nucleated cell populations found in whole blood, including both white blood cells (leukocytes) and endothelial cells, provide an ideal platform for studies seeking to understand the disease processes for development of drugs and...
Crystalline beta-Ga2O3 nanowires with two distinct morphologies have been synthesized through simple physical evaporation of Te doped GaAs powder in argon atmosphere. The structure of the nanowires was characterized by SEM, TEM, XRD, EDX, and raman...
Hemolysis (red cells lysis) caused by fluid stresses in flows within hypodermic needles, blood pumps, artificial hearts and other cardiovascular devices, is one of the major concerns during the design and use of cardiovascular or blood-processing...
Aortic Valve Bypass surgery has found renewed interest to researchers due to its application in high-risk patients with severe aortic stenosis. This therapy consists of construction of a conduit containing a bioprosthetic or mechanical valve from...
Background: Emerging circulatory support devices that operate in counterpulsation to the native heart require synchronized timing of device ejection and filling on a beat-to-beat basis with the native heart using a patient's ECG. Surface leads are...
