Research Project Aims to Eradicate Use of Harmful Gas

Posted on by

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.

Dr. Heidi Dierssen is Conducting Research to Improve Remote Sensing of Microplastics on the Ocean’s Surface

Posted on by

Dr. Heidi DierssenProfessor of marine sciences and geography, Heidi Dierssen, has received a nearly $577,000 grant from NASA to study better methods for remote sensing of surface microplastics using satellites. The project will involve a collaboration with a visual artist to advance community understanding of this problem.

Dierssen’s lab, Coastal Ocean Lab for Optics and Remote Sensing (COLORS), conducted previous research on the optical properties of microplastics, providing the necessary background information to determine the best approaches for remote detection. Understanding the optical properties of microplastics is the first step in determining whether satellites can detect and quantify floating microplastics from space.

Dierssen has assembled a diverse scientific team of experts from NASA Goddard Space Flight Center, Colombia University, University of Maryland, Baltimore County, and Terra Research Inc.

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.

IMS Polymer Program Members Inducted into UConn NAI Chapter

NAI Members and Inductees
NAI UConn Chapter members and inductees (Dr. Alexandru Asandei is 3rd from left, Dr. Richard Parnas is 4th from left).

IMS Polymer Program faculty members, Dr. Alexandru Asandei and Dr. Richard Parnas, were inducted into the UConn Chapter of the National Association of Inventors (NAI) in December 2019. The UConn NAI chapter was established in 2017 as the first Connecticut chapter of the national organization which was formed in 2010. The goal of NAI is to recognize and encourage academic inventors, enhance the visibility of academic technology and innovation, encourage the disclosure of intellectual property, educate and mentor innovative students, and translate the inventions of its members to benefit society.

Dr. Richard Parnas — whose research pursuits include biofuels production and separations, renewable polymers and composites, and interface engineering — holds a patent for a novel membrane that can be used to make biodiesel production more profitable by aiding the conversion of glycerol to 1,3 propanediol, a valuable platform chemical.

In 2018, Dr. Parnas and Trumbull, CT-based REA Resource Recovery Systems partnered with UConn and the Greater New Haven Water Pollution Control Authority (GNHWPCA) to place a pilot-scale demonstration system at the East Shore Water Pollution Abatement Facility in New Haven to convert brown grease to biodiesel fuel. The type of biodiesel fuel produced through this partnership, called Brown FOG (fats, oils, grease) can be used for power generation, including to power vehicles.

In May of 2019, U.S. Congresswoman Rosa DeLauro (CT-03) and former New Haven Mayor Toni Harp visited the joint UCONN/GNHWPCA/REA project at the East Shore facility to celebrate the successful performance of the demonstration system and to kick off the effort to place a full-scale commercial system at several wastewater treatment plants in the state. Dr. Parnas has since partnered with the city of Danbury on a project to create a biodiesel production facility at that city’s water treatment plant.

Dr. Alexandru Asandei’s research interests include controlled radical polymerization, block copolymers, fluoropolymers, catalysis, biodegradable polymers, and organometallic chemistry. He holds several patents related to his research in polymer science and has served as an editorial board member for the Journal of Polymer Science: Part A: Polymer Chemistry since 2009. Dr. Asandei has served as co-organizer of the American Chemical Society (ACS) Workshop on Fluoropolymers in 2016, 2018, 2020.

In 2015, Dr. Asandei completed a month-long visiting professorship at Pôle Chimie Balard in Montpelier, France. Asandei was selected for the Chaire TOTAL program which includes a visiting professor/researcher component, an International School on Sustainable Chemistry and Energy initiative, and a scholarship program. As part of the program, Asandei presented four invited lectures. While in France, Professor Asandei also made invited presentations at the University of Toulouse and the University of Grenoble.  Dr. Asandei has been called upon to present his research at numerous conferences, universities, and industry organizations.
