Fiber-reinforced polymer matrix composites (PMCs) using high-temperature thermoplastics as the matrix material represent a lightweight design solution for applications above 250°F. This is often required for aircraft structures subjected to...
Microhotplates for metal oxide gas sensors are fabricated using platinum microheaters and tested. Power consumption is monitored and temperature distributions are observed using infrared microscopy. Temperature line traces are extracted from the...

The one dimensional heat transfer, thermal diode effect of heat pipes makes
them ideal for passive solar applications. Gains in a heat pipe passive solar wall are not
lost during cloud cover or periods of low irradiation. An experimental model was...
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...
The heat pipe augmented solar wall operates much more efficiently for domestic air heating than alternative passive solar technologies. The thermal diode effect of heat pipes reduces the insulating losses of the unit during nighttime and adverse...
Aquatic ecosystems face major transformations as humans increasingly alter their environment by introducing exotic species and changing the temperature regime and nutrient availability of freshwater systems. The impacts of such alterations of...
In this dissertation, standardized methods for measuring electron emission (EE) from nanostructured materials are established. Design of an emitter array platform, synthesis and nanomanipulation of different types of are successfully conducted....
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...
Liquid gallium (Ga) spontaneously alloys with thin films of metals such as Ag, Au, Pt Al, and Cu at near or even below room temperature resulting in rapid self-assembly of nanostructures. In this dissertation, studies of the formation of these...
Nanoparticles are a class of materials that exhibit unique physical and chemical properties compared to those of the same material at the bulk scale. One method of enhancing the thermal conductivity, and hence the heat transfer coefficient, of a...
We have measured the temperature-dependent thermal conductivity, K(T) of single walled carbon nanotubes from 300 K to 8 K by 3w methods. K(T) exhibits linear temperature dependence in the entire temperature range. Our results are in good agreement...
Twenty-six fossil assemblages of land and freshwater molluscs from the Pliocene to the present, were collected from locations near the town of Meade, Kansas, U.S.A. and were analyzed (along with the extant molluscan fauna of Meade County, Kansas)...
The use of a fluidized bed dryer to dry acrylo-nitrile-
butadiene-styrene terpolymer was studied. Data for
fluidized bed drying were obtained from the Monsanto
Company's fluid bed dryer. Fluid bed theory, drying
phenomena, and fluid bed drying...
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...
Equations of state attempt to describe the relationship between temperature (T), pressure (P), and molar volume (v) for a given substance or mixture of substances. The ideal gas law is the simplest form of an equation of state. An ideal gas can be...
This thesis is based on work done as part of a bigger project supported by Naval Research Laboratories (NRL). A MOSIS fabricated micro hotplate is simulated using the CAD software CoventorWare. There are three different sized hotplates in one die;...
Elastomer degradation when exposed to chloraminated potable water is dependent on a number of poorly understood factors. Temperature and chloramine concentration are both believed to play roles, however, they have not been adequately defined. In...
The performance of pediatric circulatory support devices depends on the properties of pediatric blood. This study reports the measurement of the viscoelastic properties of pediatric blood at 37°C [body temperature]. The results were compared with...
The discovery of carbon nanotubes and subsequently graphene has led to an interest in carbon materials as sensing elements due to their unique properties. Graphene is a 2-dimensional material that has a large surface area that can be exposed to...
The properties of gold nanoparticles (GNP) holds promising potential for drug delivery, diagnostics, plasmonic photothermal therapy of diseases, electronics, catalysis, and photovoltaics (Liu et al., 2006; Huang et al., 2003; Thompson, 2007;...
