MSE Assistant Professor Publishes Origami-inspired Research in Materials Horizons

Student Yi Li
Ph.D. student Yi Li in Assistant Professor Wang’s group is actuating multistable, origami-inspired structures using a portable magnet.

MSE Assistant Professor Xueju “Sophie” Wang recently published her article entitled “Tailoring the multi-stability of origami-inspired, buckled magnetic structures via compression and creasing” in Materials Horizons. The study was in collaboration with Professor Teng Zhang at Syracuse University and Professor Halim Kusumaatmaja at Durham University, who led the study’s theoretical work.

According to Wang, the research originates from origami, the ancient art of paper folding. “It has inspired the design of many engineering structures for a wide range of applications, including deployable systems, self-folding machines, reconfigurable metamaterials, and DNA origami,” she says.

A key feature in the design of all these structures is their ability to have multiple stable states. The article lays out the foundation for the rational design of these structures. The work introduces two effective parameters of creasing and compression for tailoring the multistability of origami-inspired structures. Using ribbon structures as an example, a design phase diagram is constructed as a function of the crease number and compressive strain. The results show that the number of distinct stable states can be actively tuned by varying the crease number from 0 to 7 and the strain from 0% to 40%. These two parameters can be easily incorporated in the structure’s design to maximize functionality. Diverse examples were designed and demonstrated, from programmable structure arrays to a biomimetic insect and a soft robot, which can be actuated remotely by magnetic forces.

Drs. Bryan Huey (l) and Lesley Frame

Drs. Bryan Huey (IMS/MSE) and Lesley Frame (IMS/MSE) are recent recipients of the Department of Education (ED) Graduate Assistance in Areas of National Need (GAANN) grant.

Drs. Huey and Frame collaboratively applied for the award which provides fellowships, through academic departments and programs, to assist graduate students with excellent records who demonstrate financial need and plan to pursue the highest degree available in their course study at the institution in a field designated as an area of national need.

Their Careers in Advanced Materials Engineering Research and Academia (CAMERA) GAANN program will provide world-class educational, research, advising, and professional training experiences and opportunities, beyond MSE courses and laboratory research taught by established experts in a range of materials engineering specialties. They will utilize the funding to support five Ph.D. fellowships focusing on increasing the number of highly trained Ph.D. scholars from populations traditionally underrepresented in STEM.

Drs. Huey and Frame plan to provide primary and secondary faculty advisors for candidates selected for the fellowship. Each Fellow will earn credits through a novel ‘Academia Lab’ created by MSE in conjunction with the school of engineering and the UConn Center for Excellence in Teaching and Learning in order to incorporate instruction and workshops in educational pedagogy and practice, scientific writing and presenting, and mentorship skills.

The grant of ~$760K will be supplemented by funding from the School of Engineering, the Office of the Vice President for Research, the Office of the Provost, and The Graduate School.

Research Project Aims to Eradicate Use of Harmful Gas

Yang CaoThe gas sulfur hexafluoride (SF6) has been keeping our electrical grid safe from dangerous arcing and explosions since its introduction to the public in the 1930s. Developed in a General Electric lab, sulfur hexafluoride is one of the most widely used insulation gases by electrical utility companies because of its reliability and safety, but remains relatively unknown by the general public.

Starting in the 1960s, as greenhouse gases and their effect on the environment became more widely known, sulfur hexafluoride has been identified as one of the largest causes of global warming. While most educational and legislative efforts have been focused on CO2, or carbon dioxide, emissions as a big offender, sulfur hexafluoride has flown under the radar despite its staggering global warming potential: 25,200 times that of carbon dioxide.

Because of that, University of Connecticut Electrical and Computer Engineering Professor Yang Cao has been selected to receive $2.7 million in funding over three years from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) to develop a lifecycle management framework, with innovations in physics based aging modeling, aging byproducts fixation, and a low-cost, high-fidelity multi-gas leak sensor with GE Research, to help utilities make a smooth transition to a new, SF6– free electrical grid.  Read the full UConn Today story.

Recent Ph.D. Graduate Reflects on Experience as IMS Polymer Program Student

Dr. Deepthi Varghese
Dr. Deepthi Varghese

After completing a Master’s Degree in Biochemistry from St. Josephs Arts & Science College in Bangalore, India, Deepthi Varghese joined the UConn Chemistry graduate program in the fall semester of 2014. After hearing brief research presentations from the chemistry departmental faculty, she became interested in Polymer Science with Prof. Douglas Adamson, an unexpected diversion from her initial plans for a career in biochemistry into a field in which she had no experience.

Although the lack of experience created a steep learning curve, Deepthi embraced this new research direction. While she faced challenges during the first two years, looking back, Deepthi says that she gained far more knowledge than expected, including polymer science, electro chemistry, and setting up scientific research laboratories.

Deepthi also struggled with many challenges regarding science including the fact that experiments are more likely to fail than succeed; science takes far more time than initially expected; and there is never enough time to accomplish everything. Lessons like this can be applied to all aspects of life, business, and art, as well as science.

In addition to the science, Deepthi has increased her knowledge of communications, independent learning, and keeping an open mind to feedback from all sources. She realized that you never know who will have valuable knowledge.

“Keeping an open ear and open mind allows you to learn from faculty, technicians, graduate students, and undergraduate students as well,” Deepthi says. She noted that undergraduates, especially those from outside disciplines, are also able to contribute bits of knowledge to the scientific challenges of the day.

Deepthi became involved with UConn organizations, the South Asia Community (Tarang) and the Graduate School Senate, where she was treasurer and president, respectively. This experience helped her learn organizational leadership.

Looking back on her graduate experience at UConn, Deepthi says that she grew as a scientist as well as a person. She had a number of unexpected experiences that changed her in many ways, all positive. In November, 2019, Deepthi started her professional career as a TD Etch Module Engineer at Intel, Hillsboro, Oregon.
