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...
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...

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...
Residential buildings account for a large portion of total energy consumption in the United States. Residential energy usage can be dramatically reduced by improving the efficiency of building envelope systems. One such method is to incorporate...

The properties and broad applications of nano-magnetic colloids have generated much interest in recent years. Specially, Fe304 nanoparticles have attracted a great deal of attention since their magnetic properties can be used for hyperthermia...
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...
More than 50% of the total energy produced is typically rejected in the form of waste heat from various processes. The grand challenge is that most of this waste heat is released at temperatures much lower than 1000 C, which makes it difficult to...
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 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;...
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...
High solids processing of biomass slurries provides the following benefits: maximized product concentration in the fermentable sugar stream, reduced water usage, and reduced reactor size. However, high solids processing poses mixing and heat...
This research was performed to establish the feasibility of using Direct Metal Deposition (DMD) technology to deposit nickel powder to a nickel substrate. The substrate is electrodeposited pure nickel, and the material to be deposited is Metco...
The chaperone heat shock protein 90 (Hsp90) regulates physiologically and
pathological cellular processes, by binding and stabilizing kinases involved in basal
cellular functions and in cellular responses to stress, respectively. I hypothesize...
This problem originated in an attempt to make methyl glyoxal in quantity. Several methods of making methyl glyoxal are mentioned in the literature but in none of them is acetone used as a starting point. Since this seemed a new field it was decided...
This dissertation is concerned with investigating robust approaches for the control of pneumatic muscle systems. Pneumatic muscle is a novel type of actuator. Besides having a high ratio of power to weight and flexible control of movement, it also...

Arsenic exposure in drinking-water is a significant worldwide health problem. It causes adverse human health effects, such as cancer, increases the risks for others such as cardiovascular disease, and accelerates atherosclerosis. In this study, we...
The synthesis of the methyl thioperoxide-bridged dimolybdenum(V) dimer, [Mo2(NTo)2(S2P(OEt)2)2S(O2CMe)(SOMe)], was improved and the compound was structurally characterized by crystallography. The compound proved to be very stable to light and heat....
Five white canvases with pupae, steel shelves with potted flowers, bowls of sugar-water solution, table, radiators, humidifiers, and live butterflies; "There was a lyrical quality to Hirst's use of butterflies' lifecycles, both in the 1991...
A man and two boys carry signs for the Transport Workers Union. One reads, "[Employees] want more - Service - Safer running time - More heat on street cars." Another sign reads, "Louisville Railway defies the civil rights of...
Three men stand with signs on top of trolley tracks. One wears a trolley conductor's hat with the number 899 on it. Signs read, "Lou. Railway unfair to organized labor," "Lou. Railway employees want more - Service - Safer running...
