Tempo-Containing Romp Polymers As A Component For Treatment Of Traumatic Brain Injuries, Cameron H. Feriante

Honors College Theses

During a traumatic brain injury (TBI) sustained in combination with hemorrhagic shock the brain undergoes anoxic conditions resulting from swelling and blood loss. Traditional intravenous solutions are used to replace blood volume, but are unable to replace the blood’s oxygen carrying capacity. A proposed treatment based on isotonic solutions containing hemoglobin-based oxygen carriers (HBOC’s) which were intended to provide readily available oxygen was developed. However, cell-free hemoglobin was shown to have excessive oxidative potential. Polynitroxylated Pegylated Hemoglobin (PNPH) was developed to address this shortcoming. During PNPH synthesis a combination of polyethylene glycol (PEG) and (2,2,6,6-tetramethylpiperidin-1-yl)oxidanyl (TEMPO), is bound to the …

An ever-growing society that becomes more and more dependent on a finite energy source will eventually exceed its supply. Fossil fuel quantities are continuously decreasing and new solutions are needed. According to the United States Department of Transportation, over 10 billion gallons of airline fuels have been consumed in each of the past 15 years with some years over 13 billion gallons. In the meantime, fuel costs have …

Electrospun Titanium Dioxide And Silicon Composite Nanofibers For Advanced Lithium Ion Batteries, Kathleen Mccormac

Electronic Theses and Dissertations

A unique electrospinning method was implemented to fabricate composite nanofibers for lithium ion battery applications. The composite nanofibers were made of amorphous carbon, rutile phase TiO₂, and cubic phase Si nanoparticles. Sulfur was utilized as a template to form void structures within the TiO₂ nanofiber matrix. This provides the desired space for the Si expansion during the lithiation process. Phase, structure, composition, and morphology of the nanofibers were characterized using Raman spectroscopy, SEM, EDS, TGA, and powder XRD. Carbonized TiO₂ nanofibers showed a low but stable specific capacity. Si Nanoparticles demonstrated an initially high but fast …
