UConn recently received $10.5 million from the Air Force Research Laboratory (AFRL) for research on high-temperature materials and manufacturing processes. The funding will allow a team of seven faculty members from Materials Science and Engineering (Professors Aindow, Alpay, Frame, and Hebert), Civil and Environmental Engineering (Professor Kim), Mechanical Engineering (Professor Bilal), and Chemistry (Professor Suib) along with post-doctoral associates and graduate assistants to address challenges in the manufacturing of aerial systems intended to fly at high speed. Much of the four-year research project will focus on welding-related challenges for high-temperature metallic materials that are used for structures exposed to high speeds. The UConn team will combine experimental and theoretical approaches to help their collaborator, RTX, advance their manufacturing solutions. Additional project tasks address the behavior of non-metallic high-temperature materials under different processing and service conditions, additive manufacturing of high-temperature refractory metals, and the design and processing of metamaterials. These metamaterials are designed to change heat- and electro-magnetic fields in and around structures and are considered to advance the thermal management of high-temperature structures.

The new AFRL project comes at the heels of previous and ongoing AFRL projects for UConn approaching $30 million that involve over 15 faculty members from the Colleges of Engineering and Liberal Arts and Sciences with dozens of graduate students and post-doctoral associates. Covering research from functional materials and photonics to casting, welding, and additive manufacturing, the UConn team has established itself as a valuable partner for the AFRL and key industry partners, for example, Pratt & Whitney and Collins Aerospace.

Professor Rainer Hebert says of the contract, “The AFRL funding enables the UConn team to pursue materials processing research with a strong focus on industry and government relevance. Students and post-doctoral associates working on the project see firsthand how their research translates to industry. This insight will help in preparing a workforce that can pursue research excellence with a keen sense of the needs and constraints of industrial applications.”

Collaborative Research to Develop Filament-Based Hydrogels is Cover for JACS

Posted on by

Cover of JACS March 6, 2024 issue featuring Yao Lin etal. researchIn a collaborative effort, researchers from the University of Connecticut (led by Profs. Yao Lin, VJ Kumar and Xudong Yao) and the University of Illinois at Urbana-Champaign (led by Prof. Jianjun Cheng) have made an advance in the rational design of synthetic polypeptides to develop filament-based hydrogels. The work, conceptualized and realized by the graduate students Tianjian Yang (UConn) and Tianrui Xue (UIUC), has been published in the Journal of the American Chemical Society (JACS) and featured as the cover of the March 6 issue.

Building on the recent advancement of autoaccelerated ring-opening polymerization of amino acid N-carboxyanhydrides (NCAs), this study strategically explores a series of random copolymers comprising multiple amino acids, aiming to elucidate the core principles governing gelation pathways of these purpose-designed copolypeptides. The team found that the selection of amino acids steered both the morphology of fibril superstructures and their assembly kinetics, subsequently determining their potential to form sample-spanning networks. Importantly, the viscoelastic properties of the resulting supramolecular hydrogels can be tailored according to the specific copolypeptide composition through modulations in filament densities and lengths. The findings enhance our understanding of directed self-assembly in high molecular weight synthetic copolypeptides, offering valuable insights for the development of synthetic fibrous networks and biomimetic supramolecular materials with custom-designed properties.

The research was supported by NSF grants awarded to Yao Lin at UConn (DMR 1809497 and 2210590) and Jianjun Cheng at UIUC (CHE 1905097).

IMS Director Discusses Carbon Capture and Impact Mitigation

Posted on by

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.

Carbon Capture - Gel
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.
