Abstract: In the first part of my talk, my research group’s efforts on the rational design and synthesis of various metal-free or noble metal-free multifunctional nanostructured and nanoporous materials and their unique properties will be discussed. I will emphasize how chemistry enables the development of highly active, multifunctional nanocatalysts for reactions such as the oxygen reduction reaction (ORR), the hydrogen evolution reaction (HER), the oxygen evolution reaction (OER), and the hydrazine oxidation reaction (HOR)—reactions that are relevant to fuel cells and water splitting or renewable energy in general. Particular focus will be given to the various novel design and synthetic approaches (functionalization, “nanostructuring”, doping, etc.), to make a series of highly effective nanocatalysts for various reactions. Moreover, fundamental and theoretical studies that helped us to design as well as to unravel catalytic active sites on some of these materials, and the mechanisms by which they effectively transform various reactions, will be discussed. In the second part of my talk, I will demonstrate how similar synthetic approaches can lead to related nanomaterials that can serve as targeted drug delivery vehicles, antimicrobials or skin wound dressings. By exploiting the structural features, sizes, and multi-functional groups of the nanomaterials, we are able to improve the potency of many anticancer and antimicrobial agents. In many of these systems, the multiple functional groups that we rationally juxtapose on the nanomaterials are exploited to bring in functionality that is more than the simple sum of those of the constituents. Several examples demonstrating this, especially in the areas of energy conversions and storage and biological processes, will also be discussed.


Biography: Tewodros (Teddy) Asefa received his B.Sc. degree with distinction from Addis Ababa University (Ethiopia), M.Sc. degree from SUNY-Buffalo (USA) and Ph.D. degree from University of Toronto (Canada). He is currently a Full Professor in the Department of Chemistry and Chemical Biology and the Department of Chemical and Biochemical Engineering at Rutgers University at New Brunswick, New Jersey, USA. His research interests include the development of synthetic methods to a wide array of advanced functional nanomaterials and the investigation of their properties and applications in catalysis, electrocatalysis, energy, drug delivery, solar cells and environmental remediation. He held NSF CAREER Award, was the National Science Foundation American Competitiveness Fellow in 2010, and is a recipient of multiple federal research grants. He also serves as panelist for several federal and international agencies and as an Associate Editor and Board Member of several journals and scientific agencies. He holds several patents, co-edited a book on Nanocatalysis (Wiley) in 2013, and published over 185 peer-reviewed scientific papers and 9 book chapters. He served as a Visiting Professor at Kyoto University (Japan), ETH-Zurich (Switzerland) and Maringa State University (Brazil), and as a Visiting Scientist at the Czech Academy of Sciences (Czech Republic). His Google-Scholar citation record is currently 21,500+ with an h-Index of 63. He was named among Highly Cited Researchers for 2018, 2019 and 2020, which represent world’s most influential researchers with their paper citations ranking in the top 1% of their fields according to Web of Science.
