Engineering Students Make Impactful Discovery

During a chemical science experiment in fall 2022, 无忧视频 engineering students JT Griffin 鈥�23, Arpita Bhutani 鈥�23 and Pomona College student Evan Flitz 鈥�22 made a discovery that could lead to more fuel-efficient flying and driving. The group, mentored by Albert Dato, associate department chair and associate professor of engineering, identified a way to strengthen acrylonitrile butadiene styrene (ABS), a plastic widely used in the automotive, aerospace and electronic device industries, without adding a significant amount of weight to it.

After conducting a similar experiment on epoxy that produced successful results, the team was inspired to experiment with making a polymer that was lighter and stronger.

鈥淭he moment of our initial discovery was thrilling,鈥� Bhutani says. 鈥淲itnessing such notable deviations from the norm before we shifted the study鈥檚 focus only served to strengthen our dedication to the research.鈥�

, recently published by the American Chemical Society, explains how they increased the strength of ABS by over 20% by incorporating miniscule quantities of a synthesized graphene, a single thin layer of graphite.

鈥淲e all held our breaths each time a new sample was being tested,鈥� Griffin says. 鈥淲hen we realized the samples with graphene proved to be stronger than anything we tested, the room exploded with excitement. It felt like the team鈥檚 hard work had come to fruition.鈥�

Soon after the discovery, Dato helped prepare the team to present their findings at scientific conferences in Hawaii and Boston, where they described their work and fielded questions from other researchers.

鈥淓ngaging with industry experts and peers broadened our perspectives and brought us closer as a team,鈥� Bhutani says. 鈥淲hile facing challenging questions from seasoned professionals and graduate students was daunting, Professor Dato鈥檚 thorough preparation and emphasis on fundamental principles equipped us to navigate these interactions with confidence.鈥�

At Harvey Mudd, Dato researches the synthesis and applications of nanomaterials and directs the Energy and Nanomaterials Lab, in which researchers seek to develop solutions to energy and environmental challenges through applications of advanced materials.

Dato continues to present the group鈥檚 findings at conferences across the country and says his students鈥� growth as independent researchers is what he values the most from this experience.

鈥淭hey鈥檒l start in the lab and not get great results, but you learn from that and move on to conduct more experiments,鈥� Dato says. 鈥淣ext thing you know, they鈥檙e making this discovery on their own, presenting it to the world and then publishing it in high-impact journals. And that鈥檚 what you live for as a mentor, right?鈥�

Dato鈥檚 research is supported by a grant from the National Science Foundation.
