Characterization Of Platinum On Carbon Nanoparticles Selectively Coated With Titanium Nitride (Tin), Matthew Maramo
Characterization Of Platinum On Carbon Nanoparticles Selectively Coated With Titanium Nitride (Tin), Matthew Maramo
Honors Scholar Theses
Proton exchange membrane fuel cells are a promising low-carbon technology that still face problems including low durability during their normal operation cycles. At the cathode, the carbon supports of the catalysts may corrode. Atomic layer deposition of titanium nitride is performed on prepared catalyst layer samples. The purpose of the deposition is to create a thin film over the carbon supports to reduce carbon support corrosion and improve the lifespan of the fuel cell. Sheet resistances and contact angles are measured for the samples before and after the deposition, although some samples did not receive the deposition and post-deposition characterization …
Investigation Of Neoprene Medical Gloves: Analysis Of Material Properties, Durability, And Bacterial Barrier Efficacy, Amanda Agui
Investigation Of Neoprene Medical Gloves: Analysis Of Material Properties, Durability, And Bacterial Barrier Efficacy, Amanda Agui
Honors Scholar Theses
This work aims to investigate the material properties, durability, and bacterial barrier efficacy of neoprene for applications in the healthcare/medical field. A special focus on material stiffness and fatigue failure will be explored. Additionally, manufacturer regulations and testing will be inspected to ensure medical gloves made of neoprene blends have a proper lifespan for its desired application in the healthcare community. The resistance of protective gloves and its ability to withstand perforation failure will be investigated to guarantee the safety of users holds extreme importance. Lastly, an analysis of the bacterial barrier efficacy of neoprene gloves will be determined.

Hydrolytic Degradation Study Of Polyphosphazene-Plga Blends, Riley Blumenfield
Honors Scholar Theses
The synthesis and in vitro degradation analysis of thin films of poly[(glycineethylglycinato)75(phenylphenoxy)25phosphazene] (PNGEG75PhPh25) and poly[(ethylphenylalanato)25(glycine- ethylglycinato)75phosphazene] (PNEPA25GEG75) blended with poly(lactic-co-glycolic acid) (PLGA) was conducted to determine the blends’ potential for use as scaffolding materials for tissue regeneration applications. The samples were synthesized with glycylglycine ethyl ester (GEG) acting as the primary substituent side group, with cosubstitution by phenylphenol (PhPh) and phenylalanine ethyl ester (EPA) to make the final product [1]. Blends of 25% polyphosphazene, 75% PLGA and 50% polyphosphazene, 50% PLGA were …
Development Of A Sonically Powered Biodegradable Nanogenerator For Bone Regeneration, Avi Patel
Development Of A Sonically Powered Biodegradable Nanogenerator For Bone Regeneration, Avi Patel
Honors Scholar Theses
Background: Reconstruction of bone fractures and defects remains a big challenge in orthopedic surgery. While regenerative engineering has advanced the field greatly using a combination of biomaterial scaffolds and stem cells, one matter of difficulty is inducing osteogenesis in these cells. Recent works have shown electricity’s ability to promote osteogenesis in stem cell lines when seeded in bone scaffolds; however, typical electrical stimulators are either (a) externally housed and require overcomplex percutaneous wires be connected to the implanted scaffold or (b) implanted non-degradable devices which contain toxic batteries and require invasive removal surgeries.
Objective: Here, we establish a biodegradable, piezoelectric …
Optimizing Polymer Fluorescence For Explosives Detection, Rose K. Cersonsky
Optimizing Polymer Fluorescence For Explosives Detection, Rose K. Cersonsky
Honors Scholar Theses
Pyrene is commonly used for explosives detection, as when mixed with polystyrene, the fluorescence intensity of the resulting film can be used as an indicator of the presence of nitro-aromatic, nitro-ether, or nitro-amine explosives. Previous studieshave tested a three-component system including pyrene, polystyrene, and a salt, tetrabutylammonium hexafluorophosphate (TBAHP). From these previous studies, it has been seen that vapor pressure of the preparation area is a governing factor in the formation of excimers, which are instrumental in achieving and maintaining fluorescence intensity. In this study, three parameters – solution concentration, film thickness, and molecular weight of polystyrene are examined to …
