Dr. Jeffrey R. McCutcheon, Professor and Executive Director, Fraunhofer USA Center for Energy Innovation; Al Geib Professor of Environmental Engineering Research and Education, UConn School of Engineering has been announced as an inductee in the Connecticut Academy of Science and Engineering (CASE) for 2021.

Dr. McCutcheon joined UConn in 2008, after receiving his Ph.D. from Yale University in 2007. He was selected to receive the Dupont Young Professor award in 2013, one of only 14 professors worldwide to receive the honor. In 2019, as an internationally recognized expert in membrane technologies for sustainable water and energy production, Dr. McCutcheon was chosen to lead UConn’s participation in the National Alliance for Water Innovation (NAWI), a research consortium awarded a five-year, $100-million Energy-Water Desalination Hub to address water security issues in the United States.

In 2020, McCutcheon lead a team developing a prototype of an emergency ventilator that could be produced by Connecticut manufacturers to help ease anticipated shortage of the devices as the novel coronavirus continued to spread across the state.

Election to the Academy is based on the applicant’s scientific and engineering distinctions, achieved through significant contributions in the form of publications, patents, outstanding leadership, and other factors.

New inductees are scheduled to be honored at the Academy’s 46th Annual Meeting that will be held virtually on May 27, 2021

While completing her Master’s degrees in Chemical Engineering & Technology at the Beijing Institute of Technology, Yanliu Dang discovered her research area of interest, materials and catalysis. When searching for doctoral programs, she decided to come to the US in order to learn about American culture and explore research opportunities not available in China. She singled out UConn to study under the guides of one of the world’s leaders in catalysis, Prof. Steven Suib.

Her studies in catalysis at UConn led to her dissertation defense, “Design, Synthesis, and Characterization of Metal Oxide/Phosphide-Based Catalysts for Energy Applications”

In addition to catalysis, Yanliu stated that she gained significant knowledge in microscopy and material characterization. She was very grateful to have the opportunity to work on advanced instruments at UConn: Titan Themis TEM, Dual Beam FIB, and XPS to study materials and catalytic mechanisms.

Yanliu’s paper, Constructing Bifunctional 3D Holey and Ultrathin CoP Nanosheets for Efficient Overall Water Splitting, was published in July 25, 2019. Her paper, Partial Reduction of Ruthenium Oxide as Efficient and pH-Universal Electrocatalysts for Hydrogen Evolution, is currently under review. Her third paper, Self-standing Ruthenium Oxide Nanocomposite for Regenerable Electrocatalyst in Seawater Splitting, is around the corner.

Ian J. Martin and Samiksha Vaidya of Dr. Rajeswari Kasi’s research group recently attended the American Chemical Society (ACS) Fall 2019 National Meeting & Exposition in San Diego, CA and presented posters entitled “Templated perylene diimide-polydiacetylene supramolecular structures with unique chromatic transitions” and “Molecular engineering of dye incorporated liquid-crystalline polymers with different architectures”, respectively. Each of their presentations were highlighted as distinguished poster nominees in the Polymeric Materials: Science and Engineering (PMSE) division.

Mechanoluminescence (ML), also called triboluminescence (TL), refers to the phenomenon/process that materials could emit light under mechanical stimuli, e.g., friction, stretch, compression, impact, etc. The ML materials could utilize the ubiquitous mechanical energy in daily life to generate light emissions, avoiding the requirement of an artificial photon- or electron-excitation source as that in photoluminescence (PL) or electroluminescence (EL). Therefore, ML materials show great advantages in energy saving and environmental protection.

For practical applications, ML crystals or powders are required to composite with bulk matrices to generate structural non-destructive ML. Among the fabricated ML composites, elastomer-based ones have attracted increasing attention owing to the rising requirement of incorporating stress sensing characteristic into flexible/wearable devices. The present ML elastomer composites mainly employ transition metal ion doped sulfides (TM-sulfides) as the luminescent components because of their intense ML intensity. However, the TM-sulfides usually have poor chemical stability and may cause severe environmental pollution as well as lack of rich emission color.

Theoretically, rare earth doped oxides (RE-oxides) are promising alternatives because of their high chemical stability, nontoxicity, and abundant energy levels. It is essential to develop efficient and ideally multicolored ML of RE-oxide based elastomer composites, so that flexible devices may possess remarkable and environmentally friendly mechanical responsive optical characteristics.  Read the full story at Science Trends.
