Students and an alumnus of BS Applied Physics, major in Instrumentation of the College of Science won the Best Poster in the Physics Dissertation category of the 21st Samahang Pisika ng Visayas at Mindanao National Physics Conference and 2019 International Conference on Advanced Functional Materials and Nanotechnology, held from October 17-19, 2019 in Mapua University, Manila.
Winning the award were Carl Joshua M. Salundaguit (alumnus), Joseph Ian C. Abenilla, Maria Katrina Anne C. Pingul, Lariza Nes H. Lao, and Mhar Ian C. Estayan, who wrote the paper “Detection of Monosodium Glutamate (MSG) and Sodium Chloride (NaCL) using the Resistance of a Two-point Probe.”
Recognizing that MSG and NaCL are commonly used as food additives for flavor enhancement and food preservation, the study reiterated the warning that a daily sodium intake of more than 2,300 mg poses health risks. In an effort to address such risks, the Instrumentation students created an NaCL and MSG detector.
Specifically, the students created a two-point probe detector using acupuncture needles. Tests included a sensitivity test, reproducibility test, and the selectivity test.
