Stress-Sensing In Flexible Epoxy Adhesives, Christine Rukeyser
Stress-Sensing In Flexible Epoxy Adhesives, Christine Rukeyser
Honors Theses
In mechanochemistry, mechanical force causes a chemical change using small molecules, called mechanophores, by covalently connecting them into polymer materials. Stress-sensing mechanophores give a visual signal of mechanical force on the molecular level within a material. To our knowledge, stress-sensing mechanophores have never been incorporated into a commercially available epoxy kit. In this work, the characterization of two 3MTM Scotch-Weld TM Epoxy Adhesive kits: DP100 Plus Clear and DP190 Translucent have been completed through FT-IR Spectroscopy. The addition of the mechanophore spiropyran to the 3M kits will be discussed; as well as preparation and characterization of three dimerized anthracene derivatives. …

Modeling Surface Structures For The Capture Of Carbon Dioxide, Paige Freyre
Honors Theses
Our research utilized a modified graphene surface model to simulate capture of carbon dioxide and nitrogen gas based on van der Waals forces and hydrogen bonding. We completed an extensive review of the literature for model and experimental surfaces used to trap carbon dioxide and nitrogen gas into structures and pores with varying functional groups, pore sizes, and pore structures. We replicated the design of selected published models and compared their and our calculated binding energies. We used Scigress (Fujitsu) software with the Molecular Mechanics MM3 parameter set to perform calculations to analyze a proposed graphene surface pore lined with …
