It’s estimated that over 90% of American adults own cell phones while over 70% of the United States land area belongs to rural counties. It is a challenge to charge mobile devices in these remote and rural areas given the lack of access to power sources. This lack of power in remote destinations limits the general use of mobile devices for outdoor enthusiasts, as well as a survival means for all who need access to a portable power generation device, especially in emergency situations. There are other portable generators currently available on the market, but our project wanted to take …

The purpose of this project was to use COMSOL, an advanced FEM (finite element modeling) software, to analyze a Coupled Thermal Resonator. This Coupled Thermal Resonator was previously constructed in L-Edit, but when analyzed in COMSOL, it produced undesirable results. This project focused on improving the design and model of the Resonator to improve simulation results and evaluating the actual response of the MEMS device to determine if simulated results were accurate for the actual device. Many different factors may have contributed to producing the double peak seen in the simulation, including the weak coupling between the two resonators. These …

Organic electronics have become of great interest in the field of materials science research due to the potential for flexible electronic devices and low cost technologies. Difficulties emerge with creating a stable and efficient device, while still maintaining a simple and room-temperature production process.
With the advent of relatively stable organic semiconductors and graphene (or other nanotube or fullerene morphologies), it is possible to fabricate photovoltaic cells at near room temperature. By stacking these cells, devices of reasonable efficiencies >5% can be fabricated. Devices were created with a perylene-P3HT photoactive layer, polyaniline buffer layer, and PEDOT:PSS as the hole transport …
