b'A Pictorial Update or Coral and Oyster Restoration ProjectsLarra Williams, Thomas Falkenhausen, William Wilson, Jael Stanton, Mark Highsmith, Yalanda Gordon, Kiara Clark, William Blair, Rachael Davis, Jordan Gravett, Heather Tomlinson, Erin Manning, Marcus Diaz, and Chris Adam Slaton, Department of ChemistryFaculty Sponsor: Thomas Manning, Department of ChemistryStudents and faculty in the chemistry department have been developing a novel surface for the attraction, colonization and growth of oysters and corals. Oysters are a keystone species that impact a range of parameters from shoreline erosion to local fisheries. A single oyster can filter up to 50 gallons of water a day and play a key role in water quality. A project that started in Apalachicola Bay has moved to the Atlantic side of Georgia, near Skidaway Oceanographic Institute, the marine lab for the University of Georgia. The material is designed to attract diploid oyster spat, settle it with a high efficiency and grow them to full size within a year. Worldwide oyster populations have decreased 85%. Some extreme examples exist in the United States with oyster bars in the Chesapeake Bay down 99%.There is also a coral restoration project in the Florida Keys under a NOAA permit. Since deployment of materials at Pigeon key, student have taken updated images of the corals that settled and grew (surviving Hurricane Irma). Despite the storms and the human impact (algae growth due to nutrients from human activity), our novel approach has been working. The latest images of the corals will be presented and discussed. Worldwide there has been a significant decline in coral populations, attributed to the various aspects of climate change.Quantification of Acetaminophen Present in Tylenolby Cyclic Voltammetric MeasurementsNathan T. Hart, Department of ChemistryFaculty Sponsor: Dr. Linda de la Garza, Department of ChemistryCyclic voltammetric measurements were carried out on acetaminophen (APAP) solutions of various concentrations prepared in McIlvaine buffer (pH 2.42). Each solution was run four times and the highest anodic peaks in the voltammograms were averaged. Six data points were used to create the calibration curve for the current signal verses the concentration of acetaminophen in solution. The resulting calibration curve had an R2 value of 0.999, indicating an acceptable fit for the regression line of the data points. Using this calibration curve, a sample of Tylenol (reported by the manufacturer to contain 500 mg APAP) was determined to contain 81.9% APAP by weight. Therefore, a 605.2 mg pill was determined to contain 495.90 +/- 25 mg acetaminophen at the 95% confidence level .25'
