As he nears the completion of his PhD in chemical engineering, Erik Carboni has had plenty of time to acquaint himself with the useful facilities and knowledgeable staff here at the University of Connecticut. Over the years Erik has learned that if he needs a certain machine or instrument, he can easily find and use it. “If I had to describe UConn in one word, I would say that it is productive.”

The Connecticut native chose UConn knowing it was a strong school for chemical engineering. UConn’s top ranked school of pharmacy was a plus for Erik, since it enabled him to add a pharmaceutical component to his research.

Erik is investigating the flow behavior of nano and micro-particles in blood. The goal of his research is to improve drug delivery to cancerous tumors and other diseases. He finds it rewarding to contribute to treatment therapies. “If we can find the optimal size and shape that leads to maximal margination—which is the movement of particles toward the blood vessel wall—then we can maximize the delivery of nanoparticle drug carriers.”

Last October, Erik presented his work at the Society of Rheology annual meeting in Philadelphia. The talk was titled, “The Rheology of Nanoparticles in Blood for Improved Cancer Therapy.” This research offers a new perspective on mechanisms associated with margination.

Erik treasures the mentorship provided by his Ph.D. advisor, Dr. Anson Ma. “He found a project for me that he knew that I would enjoy working on. He is someone who genuinely cares about his students.”

After receiving his PhD, Erik aspires to a research position at a pharmaceutical company, but would love to teach if the opportunity presented itself.

 

 

The United States remains the top graduate destination in the world. With superior quality and flexibility in its programs, UConn has everything the best programs have to offer and more.  Third year PhD student Jie Qi stands by her decision to study Chemical Engineering here. “I chose UConn because of its strong reputation as a research University,” she says, “There are many great opportunities available to students including different internships, various options for financial aid, and a great network of alumni.”

Jie is originally from Harbin, China and received her bachelor’s degree at Dalian University of Technology in 2012. Most would consider coming to Connecticut a drastic change, but Jie adjusted to New England easily. “I love the color in fall. Storrs is a good place to study and live.” She adds, “I feel like I’m part of the school, and not just another international student in a city. I can always get help if I need it.”

Her research project under Dr. Brian Willis involves selective area atomic layer deposition (ALD) of copper. “I hope this new technique can help improve solar power technology and make it cost-competitive with fossil fuels.” Jie hopes to be able to apply what she’s learned to help ease the energy crisis by working in industry in the future.

This month Jie will attend her first conference: the AVS International Symposium and Exhibition. She will give a talk about the effects of seed layer properties and reaction conditions on ALD Cu thin films relevant to plasmonic devices.

“The engineering school has helped me develop and grow, and there is a lot of school pride at UConn,” says Jie, “The program is flexible, but challenging. I feel lucky to have the chance to complete my PhD here.”

A student team from the University of Connecticut is one of five winners in the Northeast in the Environmental Protection Agency’s P3 student design competition for sustainability research. Their achievement carries a monetary award of up to $15,000 to help fund their work, as well as an opportunity to compete for $90,000 during the second phase of the competition.

The goal of UConn’s entry, one of 42 selected nationally, is the development of a cost-effective, environmentally friendly flame retardant to be used in fire prevention and containment. In comparison to existing flame retardants, UConn’s proposal, “Environmentally Friendly Flame Retardants Based on Inorganic Nanosheets,” is designed to have similar or higher performance than products currently in use but with only a minimum release of toxic gases during combustion, and with no leak of toxic chemicals during production, transportation, and use. An additional benefit is that the cost will be similar or lower than that of currently used retardants.

Dr. Luyi Sun, associate professor in the Department of Chemical and Biomolecular Engineering, says that current fire retardants have significant environmental and health issues. The product designed by UConn students will be a waterborne, halogen-free coating composed of hundreds of layers of well-aligned inorganic nanosheets that can physically block the heat/oxygen transfer and thus effectively retard flames. Its waterborne nature ensures that no volatile organic compounds will be released during the coating formation process.

The project is an interdisciplinary collaboration between students from the Department of Chemical and Biomolecular Engineering, the Institute of Materials Science, and the Department of Civil and Environmental Engineering.

Team members include Ph.D. candidates Jingjing Liu from Materials Science, and Jingfang Yu, from Chemical and Biomolecular Engineering; seniors Lauren Kovacs, Brittany Bendel, and Arie Havasov who are Chemical and Biomolecular Engineering majors; and junior William Masinda, a Materials Science and Engineering major.

The three P’s in the EPA competition’s title stand for People, Prosperity, and the Planet. It is a two-phase team contest, where students initially prepare proposals that compete for funding of up to $15,000 to pursue their research. In April, the funded teams bring their projects to Washington, D.C., where they are judged by a panel of experts convened by the American Association for the Advancement of Science at the annual National Sustainable Design Expo. The winning team will receive a grant of $90,000 to take its design to real-world application.

Graduate students have many reasons to choose UConn, from conducting research in world class facilities, to a welcoming learning environment, and no shortage of school pride (not everyone wins dual National Championships in basketball).

“Don’t go anywhere else!” says second year PhD student David Gamliel of the Department of Chemical and Biomolecular Engineering Graduate Program. David hails from Amherst, Mass., and received his B.S. in Chemical Engineering from UMass Amherst, but his decision to pursue his PhD in Storrs was simple.

“I picked UConn because I was really interested in energy engineering, and I enjoyed the orientation. I am very lucky I ended up at the Center for Clean and Energy Engineering (C2E2),” he says.

David’s faculty advisor is Dr. Julia Valla. His research focus involves converting biomass into energy through pyrolysis. Pyrolysis, which occurs when biomass is brought to elevated temperatures without oxygen, produces an array of useful chemicals. Some of these are the same as those found in gasoline. David is studying the best operating conditions for pyrolysis, and how small scale microreactors can be scaled up to maximize the conversion of biomass to useful products.

“I feel like I am doing meaningful and impactful research,” he says of his work, which can be viewed at iknowgreen.uconn.edu. “The level of independence given to me as a student researcher was beyond my expectations.”

Another advantage of studying at UConn, David adds, “I really enjoy the opportunities to travel and present my research.” He presented at the ACS Conference in March, and attended the Energy and Fuels section dinner, a great networking event. This November he will present a poster and give a lecture at AIChE in Atlanta.

David is involved outside of the lab, too. He is the treasurer of the Chemical Engineering Graduate Student Association, and participates in outreach work. As a GK12 fellow, David shares weekly lessons about science, math and engineering at Wolcott Technical High School in Torrington, Connecticut. He is also an outreach ambassador for C2E2, and has participated in the Joule fellowship program.

“I would like to go into industry,” says David, “But I am still open to the idea of becoming a professor. “
