This annual poster competition for high school students, sponsored jointly by the American Chemical Society and St. Joseph's University, took place on Saturday, February 2, 2013 on the Brooklyn Campus. There were 92 poster presentations and 102 participants in this year’s event, making it the most well attended competition to date. Students from 7 area highs schools attended and the quality of the research was also better than ever. All of the students received certificates and the winners received Barnes and Noble gift cards.

HONORABLE MENTION
Glen R. Kowach, of the City College of New York Chemistry Department, presented the keynote address entitled Synthesis of Novel Materials and Application in Optics and Electronics. The use of novel materials has directed device design in countless ways. He focused on three examples based on materials developed in his laboratory. First, negative thermal expansion materials, such as zirconium tungstate, have permitted the fabrication of temperature compensated fiber Bragg gratings, devices used in optical telecommunication. Second, temperature independent optical materials were discovered to reduce distortion in optical devices, such as etalons for solid state lasers. Single crystals of sodium bismuth molybdenum tungsten oxide were grown to possess a temperature independent coefficient of the optical path length. Third, piezoelectric thin films of zinc oxide were developed for piezoelectric microwave-frequency acoustic resonators. The piezoelectric performance was correlated to crystallinity and stoichiometry of the thin films.
We would like to acknowledge those who worked to make this event a success:
Chairperson: Jill K. Rehmann, Ph.D.
