IMS Director Discusses Carbon Capture and Impact Mitigation

Dr. Steven L. Suib, Director of UConn’s Institute of Materials Science (IMS), is working to mitigate the effects of greenhouse gasses caused by carbon dioxide (CO2) emissions through carbon capture and conversion.  His work was recently highlighted in a UConn video.  IMS News reached out to Dr. Suib to discuss the impacts of the his research.

Dr. Suib’s research is highlighted in this video produced for UConn Today

How does carbon dioxide (CO2) negatively impact the environment and why is the research you are conducting critical to mitigating the impacts of CO2?

CO2 is a product of combustion from gas burning vehicles, industrial plants, and other sources. Enhanced levels of CO2 are believed to be responsible for global warming and the unusual patterns of weather throughout the world in recent years. We are trying to find ways to trap and gather carbon dioxide and also to transform this into materials that are less hazardous and with practical uses.

You state that CO2 must be trapped (or captured) in order to be converted.  What methodology or methodologies are used to capture CO2 emissions?

There have been many different methods suggested to capture CO2 including physical methods of trapping in porous materials as well as chemical reactions for storage.

Discovering methods of converting CO2 to harmless but useful products requires the introduction of a catalyst to convert the gas. You have conducted extensive and often-cited research in catalysis.  How does this expertise aid in your research? 

The bonds in CO2 are strong and this gas is quite stable. There are many different types of catalysts that we have made. Different reactions are often catalyzed by different catalysts. To find better catalysts they need to be synthesized. The heart of our research programs centers around synthesis of new materials. Unique new materials including catalysts may have different and beneficial properties that commercially available materials do not have.

When you use the term “harmless but useful” in describing products that can be derived from the conversion of CO2, what types of products are possible?

The objective of activating CO2 is to make products that are safe and that can be used in different applications such as new fuels, new chemical feedstocks, and others. These in turn can be used in applications involving sustainable energy, medicines and pharmaceuticals, and new conducting systems (semiconductors, superconductors, batteries, supercapacitors).

It seems we have reached a critical stage in the climate crisis with calls for more research and, above all, action to reduce greenhouse gases and their negative effects.  How urgent is the research you and your students and colleagues are conducting to the mitigation of the climate crisis?  How close is the research to producing measurable outcomes?

The field of capturing and activating CO2 is very active right now, with numerous groups around the world trying to solve problems that would allow CO2 to be eventually used in many different commercial processes. Our work involves a small set of potential materials for capture and activation of CO2. There are measurable improvements in capture and activation. The key will be to push this to the limit so practical processes can be used.

Nguyen Lab Explores Benefits of Using Microneedle Arrays for Vaccine Delivery

from UConn Today

In rural areas, especially in developing countries, the long distance to a medical facility may hinder a population from getting vaccinations, and especially booster doses.

Vaccines—for everything from influenza to COVID-19 to pneumococcal diseases—are stored at a low temperature for stability and are typically administrated through a hypodermic needle and syringe from a health care professional.

“What if we were able to mail people vaccines that don’t need refrigeration and they could apply them to their own skin like a bandage?” asked Thanh Nguyen, associate professor of mechanical engineering and biomedical engineering at the University of Connecticut. “And what if we could easily vaccinate people—once—where they wouldn’t need a booster? We could potentially eradicate polio, measles, rubella, and COVID-19.”

The answer, Nguyen believes, is administrating vaccines through a programmable microneedle array patch with a novel process he is developing at his lab at UConn.

By adhering a nearly painless, 1-centimeter-square biodegradable patch to the skin, a person can receive a preprogrammed delivery of highly-concentrated vaccines in powder form—over months—and eliminate the need for boosters. “The primary argument is that getting vaccines and boosters is a pain,” Nguyen said. “You have to go back two or three times to get these shots. With the microneedle platform, you put it on once, and it’s done. You have your vaccine and you have your boosters. You don’t have to go back to the doctor or hospital.” 

This month, UConn’s Institute of Materials Science received a three-year grant from the Bill & Melinda Gates Foundation to support Nguyen’s research on “Single-Administration Self-boosting Microneedle Platform for Vaccines and Therapeutics.” The project’s goal is to develop a low-cost manufacturing process.  

The Nguyen Research Group has already been working to thermally-stabilize vaccines and other therapeutics so they can stay inside the skin for a long period. In 2020, Nature Biomedical Engineeringpublished a study by Nguyen and his colleagues reporting that, in rats, microneedles loaded with a clinically available vaccine (Prevnar-13) against a bacterium provided similar immune protection as multiple bolus injections.  

“We’ve been able to show this technology is safe and effective in the small animal model, but now the question is, how do we translate it into the commercialized stage and make it useful to the end user, which is the human,” he said.  

With support from the Gates Foundation, Nguyen will be able to test his microneedle platform on a larger animal—a pig, which has skin similar to humans. And if the results are similar, Nguyen predicts this technology could be manufactured, at an affordable cost, enabling both domestic and global health impact.

Nguyen’s microneedle platform also caught the attention of the United States Department of Agriculture. In September, the USDA: Research, Education, and Economics division awarded Nguyen with a two-year grant for a study titled “Delivery of FMDV Protein Antigens Using a Programmable Transdermal Microneedle System.” 

The Foot-and-Mouth Disease Virus (FMDV) is a highly contagious disease that affects the health of livestock such as cows, pigs, sheep, and goats. When an outbreak occurs, the disease leaves affected animals weakened and unable to produce meat and milk. FMDV causes production losses and hardships for farmers and ranchers, and has serious impacts on livestock trade.

And while vaccines exist, like with humans, boosters are required to keep the vaccine effective.   

USDA is interested in the technology because the patch will be able to deliver the initial dose and subsequent doses, or boosters, to animals without the need for rounding up and handling multiple animals at once,” Nguyen explained. “This decreases stress on the animals and increases safety for the animals and their handlers.”

The microneedle platform is among the latest applications the Nguyen Research Group is exploring in the arena of vaccine/drug delivery, tissue regenerative engineering, “smart” piezoelectric materials, electronic implants, and bioelectronics. Since joining the College of Engineering in 2016, Nguyen has discovered a method of sending electric pulses through a biodegradable polymer to assist with cartilage regeneration; he’s designed a powerful biodegradable ultrasound device that could make brain cancers more treatable; and he used microneedle patches to deliver antibody therapies, which have been proven successful in treating HIV, autoimmune disorders such as multiple sclerosis, and certain types of cancer.  

Christina Tamburro, post-award grants and contracts specialist for UConn’s Institute of Materials Science said IMS is grateful to both the Gates Foundation and USDA for supporting Professor Nguyen’s drug delivery research.  

“This is a wonderful application of material science and this is what we’re all about. Ultimately, this is going to save lives and it can’t get better than that,” she said.

When Barrett Wells became head of the Department of Physics in 2018, he says his opinion of the department changed.

“It was such an interesting thing, to learn more about what all my colleagues were doing,” the condensed matter physicist says. “I always felt we had a good department but as I learned more details [on colleagues’ research], I thought, ‘Wow, we’re better than I thought we were.’”

Now as Wells, who goes by Barry, joins the College of Liberal Arts and Sciences as the new Associate Dean for Life and Physical Sciences, he expects he’ll experience that all over again.

“Of course, this will be different – broader, and much larger,” he notes. “But I’m looking forward to learning more broadly about all our science departments.”

Wells joined UConn in 1998, following positions at Boeing and Brookhaven National Laboratory. He became department head in 2018, where he met and worked with department heads across the CLAS Division of Life and Physical Sciences.

“Everybody’s grumbling about the same things, or they’re happy about the same things,” he jokes. “I’m hoping that sitting where I am, I can help keep the voices of the people in the departments centered in where we are going and what decisions we make.

“I want to get a clear understanding of what each unit believes their problems and strengths are, and the people involved.”

Wells will oversee the Division of Life and Physical Sciences, which comprises the Departments of Chemistry; Earth Sciences; Ecology and Evolutionary Biology; Geography; Marine Sciences; Molecular and Cell Biology; Mathematics; Physics; Physiology and Neurobiology; Psychological Sciences; Speech, Language, and Hearing Sciences; and Statistics.

“Barry is a thoughtful and experienced scientist and leader, and I’m very happy to have him,” says Ofer Harel, interim dean of the College. “His track record shows that he asks the right questions and really advocates for his faculty and staff.”

Among the unique challenges of the position, Wells says, is ensuring adequate space for laboratory research. He will work closely on these and other issues with Associate Dean for Research and Graduate Affairs Andrew Moiseff, who previously served in Wells’ role.

“Andy is a major part of the reason I decided to apply for this role,” says Wells. “He’s been wonderful to work with. It’s a little scary to try to live up to him.”

Wells says he wants to ensure people have access to resources for both interdisciplinary and disciplinary research. Research and teaching in the disciplines needs to be strong, he says, for interdisciplinary research to be successful.

As the University moves toward replacing its general education requirements – most of which are offered in CLAS – with a common curriculum, Wells anticipates that he and the other CLAS associate deans will work to ensure that the College continues to provide a diverse, liberal education to all UConn students.

“We all know we are trying to create and disseminate knowledge, and I’m looking forward to working with people who keep the core mission of the University in mind,” he says.

Inclusion is also very important to Wells, whose own home field of physics has traditionally lacked representation of women. Data also shows, he notes, that most women scientists have partners who are also scientists, which factors into where they end up making their academic home.

“People come from all over the world to work at UConn, and we have to make that a great choice,” he says. “We want to create situations that are really good for them.”

Although Wells says he has a steep learning curve to surmount, he has found the CLAS offices among the best to work with at the University. He hopes to contribute to the overall success of not just his division, but the College.

“My definition of success is that CLAS departments feel that they are running smoothly and that people are able to do their best work.”

Dr. Cato Laurencin Publishes Breakthrough Report on Rotator Cuff Regeneration Treatment

from UConn Today

A new way to regenerate muscle could help repair the damaged shoulders of millions of people every year. The technique uses advanced materials to encourage muscle growth in rotator cuff muscles. Dr. Cato Laurencin and his team reported the findings in the Proceedings of the National Academy of Sciences (PNAS) August 8th issue.

Tears of the major tendons in the shoulder joint, commonly called the rotator cuff, are common injuries in adults. Advances in surgery have made ever better rotator cuff repairs possible. But failure rates with surgery can be high.  Now, a team of researchers from the UConn School of Medicine led by Laurencin, a surgeon, engineer and scientist, reports that a graphene/polymer matrix embedded into shoulder muscle can prevent re-tear injuries.

“Most repairs focus on the tendon,” and how to reattach it to the bone most effectively, Laurencin says. “But the real problem is that the muscle degenerates and accumulates fat. With a tear, the muscle shrinks, and the body grows fat in that area instead. When the tendon and muscle are finally reattached surgically to the shoulder bone, the weakened muscle can’t handle normal stresses and the area can be re-injured again.

Dr. Laurencin along with graduate student Nikoo Shemshaki worked with other UConn Connecticut Convergence Institute researchers to develop a polymer mesh infused with nanoplatelets of graphene. When they used it to repair the shoulders of rats who had chronic rotator cuff tears with muscle atrophy, the muscle grew back. When they tried growing muscle on the mesh in a petri dish in the lab, they found the material seemed to encourage the growth of myotubes, precursors of muscle, and discourage the formation of fat.

“This is really a potential breakthrough treatment for tears of the rotator cuff. It addresses the real problem: muscle degeneration and fat accumulation,” Laurencin says.

The next step in their work is studying the matrix in a large animal. The team looks forward to developing the technology in humans.

This work was funded by NIH National Institute of Arthritis and Musculoskeletal and Skin Diseases Grant No. DP1AR068147 and National Science Foundation Emerging Frontiers in Research and Innovation Grant No. 1332329.

Department of Energy Early Career Award Recipient Yuanyuan Zhu

Yuanyuan Zhu
Dr. Yuanyuan Zhu is the only Connecticut recipient of the DOE Early Career Award for 2022.

Established in 2010, the DOE Office of Science Early Career Research Program supports the individual research programs of outstanding scientists early in their careers and stimulates research careers in the disciplines supported by the DOE Office of Science: Advanced Scientific Computing Research (ASCR), Biological and Environmental Research (BER), Basic Energy Sciences (BES), Fusion Energy Sciences (FES), High Energy Physics (HEP), Isotope R&D and Production (IP), and Nuclear Physics (NP).

Among the 83 university and DOE national lab researchers announced as recipients of the award for 2022, Assistant Professor of Materials Science and Engineering Yuanyuan Zhu is the only Connecticut researcher to receive the honor.  IMS News asked Dr. Zhu about her research and the award.

In 2019, you were appointed Director of the UConn DENSsolutions InToEM Center for in-situ TEM research at IPB Tech Park.  You have since had papers published related to the research the Center is conducting.  As we are seeing more and more evidence of the effects of climate change, how do you hope your research at the InToEM Center will assist in solving some of the problems we are now dealing with?

Yes, we have published a couple of papers since 2019 using the in-situ environmental TEM gas cell. Here you can find our full publications: https://scholar.google.com/citations?hl=en&user=HlDqamcAAAAJ&view_op=list_works&sortby=pubdate .

It’s a coincidence that the DENSsolutions’ ETEM gas cell system is named as “Climate”, because it involves gas environment for chemical reactions in a microscope. Another example is their liquid cell system, which is called “Stream” simply because the reaction stimuli involved.

There are many materials researches related to energy and environment, including climate change, that can benefit from the in-situ ETEM research. One immediate example is heterogeneous catalysis used for natural gas conversion and H2 production. And the fusion energy materials research funded by the DOE ECA is another good example.

Congratulations on receiving the Department of Energy’s Early Career Award for 2022.  What are your hopes for your research on Understanding Thermal Oxidation of Tungsten and the Impact to Radiation Under Fusion Extremes?

Fusion energy holds great promise for replacing fossil fuels for 24/7 baseload electrical power. We are excited that the DOE Early Career Award will fund our in-situ ETEM study to directly address a well-known fusion safety hazard concerning aggressive high-temperature oxidation of plasma-facing material tungsten. We hope to gain fundamental understanding of tungsten degradation in case of air-ingress scenarios that could inform the best strategy for responding to accidents, and could guide the design of advanced W-based materials that better preserve divertor integrity for even more demanding DEMO fusion extremes. Simply put it, we want to make the operation of fusion energy systems safer and more reliable.

You have several Ph.D. candidates under your advisement.  How do you hope to influence these young scientists?

Our research group provides a welcoming, supportive and inclusive working environment to drive personal success for each Ph.D. researcher. Through the first-hand work on such research projects closely to clean energy and sustainability, I believe our Ph.D. students will gain confidence and skills in research and also develop a solid sense of social responsibility.

We are seeing many more women represented in STEM.  What advice would you give to young women who may be considering a career in science, technology, engineering and mathematics?

We need everyone in STEM, and anything is possible if one follows his/her/their passion. Research is fun but progress is built on failure and resilience.
