We were productive, busy bees during the 2017-18 academic year!
Andrea Bonetto (‘18, industrial and mechanical engineering), Ethan Zeller ('19, mechanical engineering), Sheiny Tjia-Fleck ('19, chemistry), and Andrew Huffman ('18, mathematics) constructed an experimental flow apparatus with a fluctuating water level, which they programmed to be controlled by an Arduino. Andrea, Ethan, Sheiny and Andrew were all inducted into the John Deere Chapter of Sigma Xi (a scientific research honor society) last fall. This spring Bradley Wheeler ('20, mechanical engineering) also joined the group. Andrea, Ethan, Sheiny, and Bradley presented a poster at the St. Ambrose undergraduate scholars' conference and are working hard on a journal paper about the construction of our flow apparatus.
We conducted several experiments in the tank to investigate the transport of fluorescent pink microplastic particles as they flow through sand, and we continue to work on processing the data and modeling the system.
