Improving 3D Printability and Functional Performance of Polyethylene across Visible and IR Spectrums through IR Transparent Pigmentation and Polyolefin Additives
DownloadFall 2023
Polyolefin thermoplastics form a significant fraction of the world scale production of plastics and are of high interest due to their toughness, low cost, good chemical resistance and excellent IR properties. Two grades of PE: Linear Low-Density Polyethylene (LLDPE) and High-Density Polyethylene...

Improving Measurements of the Mixing State and Mass Concentration of Particulate Emissions from Aircraft Engines
DownloadSpring 2016
This research is focused towards improving techniques used to measure particulate emissions from aircraft engines, on two fronts: first, to characterize and quantify the mixing state of particulate emissions; and second, to calibrate black carbon mass instruments with a traceable mass...

Improving Portable Oxygen Concentrator Performance through the development of a New Nasal Interface
DownloadFall 2021
Long term oxygen therapy (LTOT) is used to improve survival for patients with respiratory diseases who experience chronic respiratory failure. During LTOT, supplemental oxygen is supplied to patients from an oxygen source via cannula supply tubing. Portable oxygen concentrators (POCs) are a...

Improving Utilization of Ir-Based Catalyst Layers in Proton Exchange Membrane Water Electrolyzers
DownloadSpring 2024
In order to store large quantities of intermittent renewable energy, proton exchange membrane water electrolyzers (PEMWE) can be used to produce hydrogen which can then be used in a fuel cells to retrieve the energy. One limitation of PEMWE is that the catalysts used, commonly platinum and...

Mechanical parts sustain significant wear throughout their lifetime and consequently get defects such as cracks, abrasion, erosion, or breakage. For instance, turbine blades experience high pressure and temperature fields which can cause damage, corrosion, and indentation. In this case, the parts...

In-Situ Examination of the Development of Shear Localizations that Occur in High Strain Rate Compressive Loading in Steel
DownloadFall 2019
The objective of this thesis is to investigate material failure phenomena, specifically related to localizations with applications to naval and rail steels. In order to accomplish this objective, steels commonly used in naval and rail applications were examined in quasi-static and dynamic...
