Hasan Al Ba’ba’a, visiting assistant professor of mechanical engineering, published a research paper in Mechanics Research Communications entitled "Active elastic metamaterials with equidistant solely resonant bandgaps". The research explores how elastic metamaterials, which are materials with embedded resonant substructures, are capable of reducing low-frequency vibrations by creating locally resonant bandgaps. Additionally, their periodic structure can create Bragg-scattering bandgaps, which may differ in width and frequency ranges when compared to their locally resonant counterparts. Controlling bandgaps' type, frequency range, width, and pattern of emergence can be proven advantageous for applications requiring precise control over bandgaps. To this end, a mathematical approach for designing active elastic metamaterials is proposed, enabling resonant-only bandgaps that are evenly spaced, identical in width, infinite in number, and periodically located in the frequency spectrum.

For over a decade, Union College engineers have participated in the SAE (Society of Automotive Engineers) Aero Design competition. Students compete against other national and international universities to design, build, and fly a small remote controlled airplane with challenging design goals. This year’s team competed in the Micro Class which required building a small (roughly 3 foot wingspan) plane that could carry a payload of 2 liters of water while also meeting other design requirements like minimal plane weight and short take off distance. Held in Van Nuys, CA, this year’s SAE Aero Design West competition – one might expect – should have had blue skies and calm weather. Instead, the team persevered through high winds and cold rainy conditions eventually getting their plane to fly even as many teams never got off the ground. The crowning moment was the team receiving 3rd place for their design report over dozens of larger universities. Aero team advisor, Visiting Professor Jaron Kuppers of the ME Department says of the students, “I am so proud of the team! They worked incredibly hard to design and build this plane, work together as a team, and put together their reports and presentations for competition. The team essentially fell apart during Covid years, so winning 3rd prize is even more incredible given that this group of students has also been tasked with rebuilding the team.” Not even a week later, the team is already deep in planning for next year. If you see a team member in the halls please wish them congratulations!

Chad Orzel, the Gordon Gould Associate Professor and Chair of the Department of Physics and Astronomy, was the featured speaker at an event for World Quantum Day on April 13 held at the University of Illinois in Urbana-Champaign. His talk "The Quantum Physics of an Ordinary Morning" described some of the ways that quantum mechanical phenomena show up in ordinary, mundane activities like making toast or looking at digital photos. This was part of a broader community event hosted by the Illinois Quantum Information Science and Technology Center.

Michael Sitvarin, visiting assistant professor of biology, recently released a publication entitled, "Quantifying How Natural History Traits Contribute to Bias in Community Science Engagement: A Case Study Using Orbweaver Spiders."
