Bio-Sketch: I am a high school science teacher at St. Thomas Aquinas High School in Dover, NH where I teach Biology, Marine Biology, Forensics, and Anatomy. The area of research that I am most interested in is watershed ecology. More specifically, I want to look at the environmental factors that affect the health of the watershed and how human impact can change certain parameters.
Abstract: The Memorial Bridge in Portsmouth, NH runs over the Piscataqua River, which has a very strong receding current. A platform was deployed on the bridge to serve two purposes. One, is that there are environmental sensors on the platform that collect real-time data about water temperature, water speed, salinity, and a variety of other parameters. Secondly, the platform will serve as a place to attach a turbine for tidal power generation. My research focused on data collection and comparing the Memorial Bridge data with other sensors deployed in the Great Bay watershed. With the current being so strong in the Piscataqua, there has not been such a thorough collection of data at this site. Incorporating this data with the rest of the Great Bay sensors will give us a better idea of the overall health of the watershed. It will also show us how shipping traffic can affect certain parameters. This is a long-term monitoring project that will yield valuable information that can be used for management of the Great Bay watershed.
Biosketch: Sean Colligan is a high school science teacher. He is going into his fourth year teaching at Goffstown High School, his alma mater, where he has taught physical science and will begin teaching physics and space science this fall. Sean also enjoys coaching cross country and track and field at the high school and middle school levels. When he is not at school, he can be found at the gym, traveling, or playing with his many canine friends.
Abstract: Aqueous energy storage devices may provide a safer, cheaper alternative to typical lithium-ion rechargeable batteries, and can be integrated into the energy grid. Nanomaterials with a layered structure can be used to compensate for these devices’ typically lower energy densities, because they allow for easier transportation of alkaline cations through the material. In this project, the electrochemical performance of electrode materials and electrolytes was tested to study their viability for future device development. Manganese oxide was used for the electrodes because it exhibits a strong, capacitor-like response in aqueous electrolytes. A procedure for successfully fabricated electrodes was developed.
Cyclic voltammetry showed lower than optimal energy storage, but further testing is needed to produce exfoliation of nanoparticle layering.
