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 …

This work focuses on improving the fluorescence intensity of cerium oxide (ceria) nanoparticles (NPs) through added plasmonic nanostructures. Ceria nanoparticles are fluorescent nanostructures which can emit visible fluorescence emissions under violet excitation. Here, we investigated different added plasmonic nanostructures, such as gold nanoparticles (Au NPs) and Cadmium sulfide/selenide quantum dots (CdS/CdSe QDs), to check the enhancement of fluorescence intensity emissions caused by ceria NPs. Different plasmonic resonances of both aforementioned nanostructures have been selected to develop optical coupling with both fluorescence excitation and emission wavelengths of ceria. In addition, different additions whether in-situ or post-synthesis have been investigated. We found …

Thermoelectric Porous Mof Based Hybrid Materials, Engelbert Redel, Helmut Baumgart
Electrical & Computer Engineering Faculty Publications
Porous hybrid materials and MOF (Metal-Organic-Framework) films represent modern designer materials that exhibit many requirements of a near ideal and tunable future thermoelectric (TE) material. In contrast to traditional semiconducting bulk TE materials, porous hybrid MOF templates can be used to overcome some of the constraints of physics in bulk TE materials. These porous hybrid systems are amenable for simulation and modeling to design novel optimized electron-crystal phonon-glass materials with potentially very high ZT (figure of merit) numbers. Porous MOF and hybrid materials possess an ultra-low thermal conductivity, which can be further modulated by phonon engineering within their complex porous …
