Suib and Poyraz have patented their process for synthesizing thermally stable mesoporous transitional metal oxides. Their process also allows them to control the size of the mesopores and nano-sized crystalline walls.

Mesoporous materials have many advantages when it comes to developing materials for practical applications. They have narrow pores with a high surface area, biocompatibility, and low toxicity for use in human medical practices. They can be used for drug delivery systems, as catalysts for chemical reactions, electrodes in electrochemical energy storage for batteries, and supercapacitors, diagnostics, absorbing pollutants from water or storing gases and chromatography.  Read the full story from UConn Today

Drs. C Barry Carter (PI) and Avinash Dongare (co-PI) have been awarded an NSF GOALI grant for their collaboration with the Yardney Division of EaglePicher and co-PI Dr. Arthur Dobley. The project, Mechanisms of Lithiation and Delithiation Reactions in Layered Materials Combining Transmission Electron Microscopy and Atomic Scale Modeling, focuses on understanding how batteries work at the atomic level.

The NSF GOALI grant seeks to stimulate collaboration between academic research institutions and industry. Special interest is focused on affording opportunities for interdisciplinary university-industry teams to conduct collaborative research projects, in which the industry research participant provides critical research expertise, without which the likelihood for success of the project would be diminished; faculty, postdoctoral fellows, and students to conduct research and gain experience in an industrial setting; and industrial scientists and engineers to bring industry’s perspective and integrative skills to academe.

“By working with engineers and chemists at the Yardney Division of EaglePicher, undergraduate and graduate students gain a broad practical understanding of batteries, while also developing the expertise and skills necessary to improve these batteries. In doing so, students need a combined understanding of ceramics, materials science, physics, chemistry and electrochemistry.” the researchers explain.

The project combines in situ experimentation in the transmission electron microscope with atomic scale modeling methods to improve our understanding of how lithium and sodium move into and out from layered materials (i.e. intercalation).

The grant of $440,402 will cover the period July 1, 2018 to June 30, 2021. For more information on the GOALI grant follow this link.

The US Navy is a big proponent of additive manufacturing technology, and its use of 3D printers on ships offers self-sustainability in remote areas, allowing sailors and officers to make and repair their own tools, parts, and components on board while out at sea, rather than having to go back in to port. It is disruptive and expensive, not to mention time-consuming, to bring a ship all the way ashore just to fix a small problem like a broken part, but a team of engineers from the University of Connecticut (UConn) has been hard at work developing a solution to this problem.

The UConn engineers have found a way for a Navy ship’s crew to determine the exact point of mechanical trouble on board the ship, which would negate them having to take the ship offline for maintenance. Instead, they could use 3D printing technology to fix, or replace, the bad part while out at sea, saving on both time and money.

Associate Professor of Materials Science and Engineering Rainer Hebert, who is also the Director of the Pratt & Whitney Additive Manufacturing Innovation Center at UConn, is leading the research team. The engineers created a device which uses ceramics, on 3D printed metals, to find signals about potential problems and degradation on board, like overheating.  Read the full 3D Print story.

Board of Trustees Distinguished Professor of Chemistry and Director of the Institute of Materials Science, Steven L. Suib has some advice for early career faculty and student researchers who are interested in inventing. Given that Suib was recently named a fellow of the National Association of Inventors (NAI), it would probably be smart to grab a pencil.

“Ask a lot of questions, know the literature, don’t be afraid to move on from ideas that just aren’t working. But above all, keep an open mind and work with other people,” offered Suib.

Throughout his nearly 40-year research career, Suib has lived by these words. As a preeminent expert in solid state chemistry and the synthesis of novel materials with a strong environmental focus, his work has produced numerous discoveries with a variety of applications in several industry sectors.

Designated a “Chemical Pioneer” by the American Institute of Chemists in 2005, Suib holds more than 31 U.S. patents and has disclosed well over 100 inventions, the most of any UConn faculty member. He joins three other colleagues who have previously been named NAI Fellows – Dr. Pramod Srivastava, Dr. Cato Laurencin, and Dr. Lakshmi Nair all from UConn Health. Suib is UConn’s first NAI Fellow from the Storrs or regional campuses.  Read the full UConn Today story.
