After 19 years as a faculty member of the Institute of Materials Science Polymer Program and Chemical and Biomolecular Engineering Department, Professor Richard Parnas retired in August 2020 from the University of Connecticut.

Dr. Parnas summarized his career choices over the past 30 years stating, “My career was shaped by my desire to create environmentally responsible materials and energy solutions”.  His words and resume both reflect his passion to helping the environment. Since completing his bachelor’s degree, Dr. Parnas has worked for big industry, government, and academia on a variety of projects relating to environmental issues.

After completing his bachelor’s degree in chemical engineering at MIT, Dr. Parnas joined Exxon Research & Engineering in Florham Park, NJ. There he worked on his first environmentally friendly project, coal gasification. He helped engineer a proposed plant for Europe that would convert coal into methane at the rate of 30,000 tons per day. Although the project never came to fruition, this was the first of many environmental projects. Exxon’s abandonment of the project led Dr. Parnas to return to school. He completed his master’s degree, and later his Ph.D., at U.C.L.A.

Upon completion of graduate school, he spent 10 years in the polymers division at the National Institute of Standards and Technology, first as a chemical engineer, then as a composites group leader. His research was based around manufacturing technology. The main focus was to create new lighter weight materials for cars in an effort to increase gas mileage and reduce CO2 production. While at NIST, Dr. Parnas met Prof. Anthony DiBenedetto of the IMS Polymer Program while hosting an international meeting on composites processing, initiating his association with and eventual move to join IMS.

In 2001, Dr. Parnas was hired by IMS as a faculty member of the Polymer Program. His initial research interest was polymer composites and renewable polymers created from plant protein. Starting in 2005, Dr. Parnas became involved with a number of aspects of the world of biofuels. This changed his research direction and ultimately his career path. He ran the annual Biofuels and Sustainable Energy Symposiums at UConn from 2005 to 2010. These events were key to opening communications between state representatives, local industry professionals, and scientists from the university. It enabled discussions regarding the technical components, policies, and financial aspects of energy. The conference included as many as 300 participants, including 25 state and federal representatives such as Rosa DeLauro and John Larson.

In 2007, an undergraduate asked Dr. Parnas for help with a biofuels project. This simple question led Dr. Parnas down a path to three patents, the creation of a business, and eventually a new career. The original project led the student to a Ph.D. and a faculty position at Oregon State.

A collaboration with IMS Director Steven Suib and other University faculty landed a 1.2 million dollar Department of Energy grant to support biofuels research at UConn. This was a stepping stone to Dr. Parnas’ s research. The funding increased the research staff, enabling publications and further supporting his reputation in the field. He was elected to the Connecticut Academy of Science & Engineering in 2013. After seven patents, he was also inducted into the UConn chapter of the National Academy of Inventors in 2019. During this time, he developed a novel transesterification reactor for the efficient conversion of triglycerides to biodiesel. The reactor was patent worthy and a key component to his future company.  In 2018, after 11 years of research and three U.S. patents, Dr. Parnas created REA Resource Recovery Systems, LLC. The company processes brown grease, sourced from wastewater treatment plants, into biodiesel. The end result is less waste and reduced carbon emissions. This benefits the company, local government, and our mother earth.

In addition to education and research, Dr. Parnas spent five years as the faculty director for UConn’s EcoHouse, one of the learning communities on the Storrs campus. Participating students dedicate their time to a variety of environmental issues, such as sustainable energy, farming, and government policies. At the UConn Spring Valley Student Farm, students grow food for dining services at the Storrs campus. They learn about both farming and selling their products.  A team of engineering students also worked on solar energy, both photovoltaic and thermal, to support the farm. As faculty director, Dr. Parnas was able to help students bring their specific set of skills and interests to the learning community.

Dr. Parnas’s lasting contributions to the University are tremendous, setting a tone for engaging students and inspiring interest in the ways that modern science interfaces with our ecological footprint.  Helping to educate hundreds of students and introducing dozens to the wonderful world of scientific research, many UConn undergraduate engineers and chemists received their first experience in a scientific setting under the advisement of Dr. Parnas. This experience helped pave their paths to a career or graduate school. This August, Dr. Parnas retired from his faculty position at UConn to focus his time and efforts on his growing company, REA Resource Recovery Systems, LLC.

It’s a big world out there when it comes to wine, the libation made from fruit of the vine.

Enter Dr. Thomas Seery, IMS faculty member and Associate Professor of Chemistry, who teaches a class on “Understand-ing Wine Chemis-try.”

Seery lands in the right place at the right time when he makes his connections. He’s been teaching this class in Shanghai in the summers. Through a series of fortunate events, including passport control, meeting wives of professors and a group of scholars coming to UConn, Seery brings his interests in wine to the college community and beyond.

Throughout my Zoom interview, I heard words like tannins, retronasal, terpene and umami. Umami is a category of taste in food. I thought there were only four basic tastes, but there are more. It’s related to the flavor of glutamates.

UConn Researcher Invents Nanoparticle for Overcoming Leukemia Treatment Resistance

UConn associate professor of pharmaceutics Xiuling Lu, along with professor of chemistry Rajeswari M. Kasi, was part of a team that recently published a paper in Nature Cell Biology finding a commonly used chemotherapy drug may be repurposed as a treatment for resurgent or chemotherapy-resistant leukemia.

One of the largest problems with cancer treatment is the development of resistance to anticancer therapies. Few FDA-approved products directly target leukemia stem cells, which cause treatment-resistant relapses. The only known method to combat their presence is stem cell transplantation.

Leukemia presents unique treatment challenges due to the nature of this form of cancer. The disease affects bone marrow, which produces blood cells. Leukemia is a cancer of the early blood-forming cells, or stem cells. Most often, leukemia is a cancer of the white blood cells. The first step of treatment is to use chemotherapy to kill the cancerous white blood cells, but if the leukemia stem cells in the bone marrow persist, the cancer may relapse in a therapy-resistant form.

Fifteen to 20% of child and up to two thirds of adult leukemia patients experience relapse. Adults who relapse face a less-than 30% five-year survival rate. For children the five-year survival rate after relapse is around two thirds. When relapse occurs, chemotherapy does not improve the prognosis for these patients. There is a critical need for scientists to develop a therapy that can more effectively target chemotherapy-resistant cells.  Read the full UConn Today story.

Dr. Chris Monteleone: Reflections on an IMS Ph.D. Graduate

by Osker Dahabsu, Institute of Materials Science

Dr. Chris Monteleone
Dr. Chris Monteleone

Dr. Christopher Monteleone completed his final defense and Ph.D. in Materials Science in May 2020. Chris began his education in UConn’s Chemical Engineering undergraduate program in 2010. During his sophomore year he was offered a research position in the ceramic’s laboratory of Dr. Steven L. Suib. The lab’s focus is coatings deposited by chemical vapor deposition for composites. Interest in these materials and processing led Chris to pursue minor degrees in both Chemistry and Materials Science & Engineering.

Chris was encouraged to leave UConn for graduate school, however after some investigating, he realized his current lab was conducting cutting edge research that was unmatched and could lead him to a career. He remained at UConn to complete his Ph.D. in Materials Science. Chris’s thesis title was, “Design of Materials and Processing Methods for High Temperature Composites.”

Chris said he’s “grateful for the support he received at both IMS and Chemistry.” The open collaborative attitude helped him grow as a scientist and make achievements that might otherwise be impossible. Outside of research, Chris was offered an opportunity helping the mechanical testing and microscopy labs at IMS. This gave him experience in both professional communications and writing technical reports, excellent preparation for an industrial position.

Chris recently began his career as a Materials Engineer at the Rolls Royce High Temperature Composites lab in Cypress, California.

UConn, Army Research Lab Collaborate on New Portable, Renewable Energy Technology

UConn’s Associate Dean for Research and Industrial Partnerships, S. Pamir Alpay, and Yomery Espinal ’18 Ph.D. (ENGR) have published a paper on a novel portable pyroelectric technology in Cell Reports Physical Science with support from the Army Research Laboratory.

Pyroelectric energy research is focused on how to generate energy from heat that would otherwise be wasted in a catalytic chemical reaction.

When pyroelectric materials are heated, their polarization changes, leading to an electron flow that generates energy. These materials are commonly used in household devices like motion sensor lights, which detect body heat to determine when someone is near.

nytime there is a catalytic reaction, heat is generated. These devices harness that heat and use it as energy. For example, a combustion engine in a car produces heat that, with this kind of technology, could be used to power the electrical functions of the car that otherwise rely on battery power.

The Army Research Lab (ARL) is particularly interested in this technology because it can provide more power with less weight, which is important for soldiers carrying heavy bags.

While scientists have been experimenting with pyroelectric power for decades, the technology proposed in this paper is completely novel.

“Something like that doesn’t exist,” Alpay says. “It would give you the opportunity to recover some things that just go to waste.”

Dr. Laura Pinatti

Dr. Laura Pinatti, manager of the IMS Thermal Analysis Laboratory, is soft-spoken and avoids the spotlight but she is also funny and caring, devoted to family, and amazing at her job. After 20 years working for the IMS Industrial Affiliates Program, Laura retired at the end of April. IMS News reached out to Dr. Pinatti with a few questions.

How did you come to the sciences and, specifically, analysis and characterization?
When the job for a research assistant in the thermal lab opened up in 2000 I jumped at the opportunity. My youngest had just turned 5 and it was time to get back to work. I couldn’t have found a better place to spend the next 20 years.

What did you like most about your job in IMS?
Working for IMS and for the IAP has been challenging and stimulating with always something new to keep it interesting. I loved working with our team to define and solve the ever-increasing complexity of issues that industry continue to face.

You’ve retired in the age of coronavirus where we are working and socializing remotely.  Of course there are plans to celebrate you when it is safe, but does having such a major event in these times feel different than what you expected?
Retiring when everything is shut down is obviously not how I expected to say goodbye.  I would have liked to shake some hands and share some hugs.

How will you remember your time in IMS?
I, of course, also enjoyed meeting and working with the all the graduate students over the years. Getting to know them, working with them on the instruments and learning about their research added a whole new layer of enjoyment to my life at IMS. But what I am going to miss most is chatting with the friendly faces in the halls and offices throughout IMS.

Do you have any special plans for your retirement years?
I am looking forward to a no-obligation, nowhere-to-be sort of retirement.  My priority is my family and my health and some road trips to new places now and then.
