Congratulation to Mohammadmehdi Aghelinejad and Ji Eun (Jamie) Lee of winning the Best Presenter Awards among Ph.D. students and Master students, respectively, on the Graduate Seminar Day in the Department of Mechanical Engineering. It is also an exceptional achievement for Mohammadmehdi as he has won this award for consecutive years. Their findings in developing novel strategies to enhance the thermoelectric and piezoelectric properties of polymer-based material systems have demonstrated great potentials to promote environmental sustainability through harvesting energy from different sources.
