Novel Fluorous Hybrid Surface Modification Characterized by Wetting Dynamics, Morphology and Nanomechanics
<p>The surface response of a polymer substrate to external stimuli such as initial wetting is controlled by the outermost molecular layer. Thus, changes on the nanoscale may be engaged to control macroscale wetting behavior. Our work has predominantly focused on surface modification of conventional …

Using polymer electrolyte membrane fuel cells in a hybrid surface ship propulsion plant to increase fuel efficiency
An increasingly mobile US Navy surface fleet and oil price uncertainty contrast with the Navy's desire to lower the amount of money spent purchasing fuel. Operational restrictions limiting fuel use are temporary and cannot be dependably relied upon. Long term technical research toward improving …

Fabrication, characterization, and wettability analysis of a microstructured hybrid hydrophobic/hydrophilic surface
This thesis explores the effects of surface chemistry and geometry on wettability of Hybrid Surfaces. The Hybrid Surfaces are composed of many micropillars with hydrophobic sidewalls and hydrophilic tops. The surfaces are designed with stable dropwise condensation in mind, which can increase heat …

Understanding the Toxicity Effects of Nanostructures: I. Effect of Physico-chemical Properties on Environmentally Relevant Organismal Toxicity. II. Design of Novel Nanostructures to Reduce Environmental Toxicity while Retaining Functional Properties
… be necessary for shape-based phytotoxicity. The surface reactivity was experimentally calculated for each nanomaterial to determine if different surface reactivity between different AgNM shapes could further explain phytotoxicity. It was shown that this value correlated to phytotoxicity, …
