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.
I am a 7th year teacher, teaching Math and Social Studies at Rye Junior High School. I graduated Summa Cum Laude from UNH with a Bachelor of Science degree in Middle School Math Education with Honors (2010) and a Master of Education degree in Secondary Education (2011). This is my second year completing the RETE program. Last year, I created a predictive equation modeling fatigue cracking in asphalt pavement mixtures. I am interested in research involving mathematical applications in science and engineering fields.
This Life Cycle Assessment compares the Cumulative Energy Demand (CED), Global Warming Potential (GWP) and Cost and Benefit of Traditional and Solar Water Heating Systems. It compares a hybrid system composed of a flat plate, thermosyphon solar hot water system and natural gas supplement to a pure natural gas system when used for an average single family home in five different U.S. cities in order to assist consumers in choosing between solar and traditional hot water systems based on their geographic region. SimaPro and Excel were used to determine and calculate the impact per function unit: 1 gallon of water heated to 145.4°F. It considers impacts across the life cycle from cradle to grave including construction, operation, and end of life. The CED and GWP are highest in the Operation phase due to supplementation with natural gas. Boston has the lowest CED per gallon of hot water, Los Angeles has the lowest GWP per gallon of hot water, and Chicago has the highest CED and GWP per gallon of hot water. The only city in which the cost per gallon of hot water of the hybrid system is lower than the cost of the traditional system per gallon of hot water Phoenix. The costs of the two systems in all other cities are comparable.
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.

I am starting my fourth year of teaching this coming school year (2017-2018). I will be teaching physics, astronomy, physical science, and principles of technology at Mascenic Regional High School. I have a strong passion for learning, but I am particularly interested in oceanography, renewable energy, and climate change. In my free time (what is that?) I love reading, hiking, kayaking, knitting, and riding my motorcycle.
TiO2 is a cheaper alternative for photocatalytic conversions allowing for the conversion of CO2 into CH4 and CO. Doping TiO2 with nitrogen compounds, like urea, has been shown to enhance the absorption of TiO2 from the UV into the visible portion of the spectrum. This study showed that N-TiO2 treated at 400 °C and 500 °C significantly produced CH4 and CO.
