Fused-Molecular Systems For Organic Light Emitting Diodes, Avinash Jami
Masters Theses & Specialist Projects
Organic light emitting diodes (OLEDs) are electronic devices made by sandwitching organic light emissive materials between two electrodes. When voltage is applied across the two conductors, a bright light is generated. The color of the emitting light depends on the band gap of the semiconducting material. The work described here focuses on designing and synthesizing narrow band gap molecular systems derived from fused-arene derivatives for producing organic blue light emitting diodes. Three molecular systems derived from anthracene, pyrene, and carbazole, were designed and synthesized. Two molecular systems of anthracen-9-ylmethyl anthracene-9- carboxylate and pyren-1-ylmethyl 4-bromobenzoate were synthesized through Steglich esterification reaction …

Investigation Of Asymmetric Impacts On Protective Headgear, Kristina Medero
Mahurin Honors College Capstone Experience/Thesis Projects
This project explores helmet-to-helmet impacts and their detriments with a unique perspective. The propagation of dangerous waves into the brain can result in a concussion. Considering 60% of NFL players have had at least one concussion (Epstein 2011), it is imperative to understand the materials that construct helmets and observe how these materials behave in regards to impact location while recording wave propagations from the impacts. This study interrogates the effect of asymmetric impacts on gridiron football helmets using the Large Chamber Scanning Electron Microscope (LC-SEM). Utilizing two standard issued football helmets made of polycarbonates, a hard plastic, vibrations from …

Surface Microstructure Evolution Of Metallic Specimens Using The Large Chamber Scanning Electron Microscope, Grace Egbujor
Surface Microstructure Evolution Of Metallic Specimens Using The Large Chamber Scanning Electron Microscope, Grace Egbujor
Masters Theses & Specialist Projects
An initial study into the use of the large chamber scanning electron microscope (LCSEM) to interrogate the surface microstructure evolution of metallic specimens has been carried out. The LC-SEM located at Western Kentucky University is the largest instrument of its type at any university in the world. As such, unique measurements can be performed due to the size of its chamber and extended view of its optic system. Strain was varied for each individual specimen, and imaged using Secondary Electrons within the gauge length as well as near the grip position. Results will show progression of surface microstructures and nickel …

Generating Random Walks And Polygons With Thickness In Confinement, Sai Sindhuja Veeramachaneni
Masters Theses & Specialist Projects
Algorithms to generate walks (chains of unit-length, freely-jointed segments) and polygons (closed walks) in spherical confinements have been developed in the last few years. These algorithms generate polygons inside spherical confinement based on their mathematically derived probability distributions. The generated polygons do not occupy any volume { although that would be useful for some applications. This thesis investigates how to generate walks and polygons which occupy some volume in spherical confinement. More specifically, in this thesis, existing methods described in the literature have been studied and implemented to generate walks and polygons in confinement. Additionally, these methods were adapted to …
