MSE PhD Candidate Encourages Other Female Researchers to Not Doubt Their Own Voices

February 10, 2022

As of 2021, female PhD researchers like Suman Kumari are welcoming the challenge of pursuing a passion in a still male-majority field. Though representation has improved compared to decades ago, the imbalance in a classroom or lab can still be intimidating. According to Kumari, though it hasn’t been easy being a female in her discipline, this shouldn’t dissuade others from pursuing materials science and engineering.

“Though the world is changing, it’s challenging as a female in the materials science and engineering field, but nothing is impossible if you have the will to do it. I would say, ‘listen to yourself, you know what you want to do,” she says.

In much of her career so far, Kumari has not let any hesitation stop her.

Xueju “Sophie” Wang Receives NSF CAREER Award

Xueju "Sophie" Wang MSE Assistant Professor Xueju “Sophie” Wang has been awarded the NSF Faculty Early Development Program CAREER Award for her proposal entitled “Mechanics of Active Polymers and Morphing structures: Determine the Role of Molecular Interactions and Stiffness Heterogeneity in Reversible Shape Morphing.” It is one of NSF’s most prestigious awards.

Wang’s NSF CAREER award will support her research on fundamental studies of the mechanics of innovative active polymers and morphing structures. Soft active polymers that can change their shapes and therefore functionalities upon exposure to external stimuli are promising for many applications, including soft robotics, artificial muscles and tissue repair. This research project aims to establish the missing correlations across the molecular, material and structural levels of novel active polymers for their rational design, manufacturing and applications, by using liquid crystal elastomers as a model material system.

“I am very grateful and honored to receive this prestigious award, and I look forward to working with my students to address challenges in innovative active polymers and to apply them in emerging fields like soft robotics,” Wang said.

MSE Assistant Professor Publishes Origami-inspired Research in Materials Horizons

November 1, 2021

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.

Research Project Aims to Eradicate Use of Harmful Gas

The 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.
