Atomic Force Microscopy Of Poly(Ethylane-Oxide) Crystalization, Xavier Capaldi
Atomic Force Microscopy Of Poly(Ethylane-Oxide) Crystalization, Xavier Capaldi
Honors Theses
Polymer crystallization is a complex process which is influenced by a variety of factors. Atomic force microscopy is used to explore the material properties of polymer crystals. Poly(ethylene-oxide) is used in a variety of molecular weights as the sample. In addition, a variety of sample preparation methods and microscopy modes were tested. A relatively new imaging technique was identified for the characterization of polymer crystals: amplitude modulation-frequency modulation viscoelastic mapping. This mode was used to measure material properties such as stiffness and dissipation.

Gasoline Confined In Nano-Porous Media, Matthew Giso
Honors Theses
The heat of combustion was determined for gasoline confined in nano-porous media of differing pore size by bomb calorimetry. The heat of combustion of the confined fuels was comparable to that of bulk within the experimental uncertainty. This suggests that all of the confined fuel burns without any flame quenching and no chemical interactions at the interface between pore walls and fuel mitigate combustion.
