Masters Theses
Supercritical carbon dioxide (sc-C02) is an excellent green solvent, but its properties are not thoroughly understood. For example, fluorinated compounds have higher than expected solubility in sc-C02. Microwave spectroscopy is one way to learn more about sc-C02 because it can be used to determine detailed structures of small clusters of molecules. The purpose of this investigation was to study weak hydrogen bonding interactions in complexes of fluorinated ethylene (solute) with carbon dioxide (C02, solvent). Investigations on dimers with one C02 molecule and fluorinated ethylene were carried out previously and found two different …

Siloxane And Silane-Functionalized Polynorbornenes As Membranes For Passive Carbon Dioxide Separation, Eunice Koheun Hong
Masters Theses
In 2012, carbon dioxide (CO2) [carbon dioxide] accounted for approximately 82% [percent] of all U.S greenhouse gas emissions.1 These excessive CO2 levels have been attributed to climate changes that have a range of negative effects on human health and welfare.1 In an effort to decrease these emissions, polymeric membranes consisting of silane- and siloxane-functionalized norbornene units have been targeted as a potential solution for the passive separation of CO2 from other non-greenhouse gases. These substituted norbornene-based polymers were synthesized via vinyl-addition polymerization. Through a series of catalyst trials, commercially available palladium and nickel catalysts were compared along …
