Among six Mellon College of Science (MCS) faculty members, Ben Hunt has been honored with a career development professorship that supports scientists at the beginning of their careers. He and the other faculty were recognized at a reception Sept. 12 in the Mellon Institute. “An endowed professorship is one of the highest honors that our institution bestows upon faculty, and this honor symbolizes the high esteem to which they are held,” said Carnegie Mellon University Provost Jim Garrett.

“Each of these faculty members are being recognized for their important work in fields that will be some of the most important of the 21st century,” said Rebecca W. Doerge, Glen de Vries Dean of the Mellon College of Science. “While their discoveries will make a significant impact in the world, that impact is equaled by their contributions to the students who they teach in class and mentor in the lab.”

The Stephen R. Tritch Nuclear Engineering program at the University of Pittsburgh’s Swanson School of Engineering has received three substantial grants from the U.S. Department of Energy’s (DOE) Nuclear Energy University Program (NEUP) totaling $2.3 million. PQI faculty members Dr. Heng Ban, Dr. Jung-Kun Lee, and Dr. Kevin Chen are among the recipients.

The awards are three of the 40 grants in 23 states issued by the DOE, which awarded more than $28.5 million to research programs through the NEUP this year to maintain the U.S.’s leadership in nuclear research. 

“Nuclear energy research is a vital and growing source of clean energy in the U.S., and we are at the forefront of this exciting field,” says Heng Ban, PhD, R.K. Mellon Professor in Energy and director of the Stephen R. Tritch Nuclear Engineering Program at the Swanson School of Engineering. “These grants will enable us to collaborate with leading international experts, conducting research that will help shape future of nuclear energy.” 

Congratulations!

Prof. Lillian Chong has been awarded an NIH RO1 renewal for $1.1 million over 4 years to pursue efforts involving "High-Performance Weighted Ensemble Software for Simulation of Complex Bio-Events." The efforts will be carried out in collaboration with co-PI Prof. Daniel Zuckerman (Oregon Health & Science University), co-I Prof. James Faeder (University of Pittsburgh Medical School), and co-I David Aristoff (Colorado State University). 

Congratulations Dr. Chong!

Qing Li, assistant professor of electrical and computer engineering at Carnegie Mellon University, is the recipient of a prestigious 2019 Young Faculty Award from the US Defense Advance Research Projects Agency (DARPA). He received the award based on his research proposal titled "Visible and mid-infrared frequency comb generation in wide-bandgap photonic materials."


Giannis Mpourmpakis awarded NSF for screening catalysts

The National Science Foundation has awarded Giannis (Yanni) Mpourmpakis $354,954 to continue his research into a promising but poorly understood method of creating olefins. Olefins, simple compounds of hydrogen and carbon, serve as the building blocks in chemical industry and are important for the synthesis of materials, including polymers, plastics and more. However, creating them can be problematic: it requires the use of fossil fuels, energy intensive “cracking” facilities, and limited production control. The team in Dr. Mpourmpakis’s CANELa lab will use computational modeling and machine learning to understand how the dehydrogenation of alkanes takes place on metal oxides, and use that knowledge to screen a wide range of metal oxides and their properties for use in the process.

Congratulations Dr. Mpourmpakis!


Jyoti Katoch receives DOE Early Career Grant to probe quantum matter

Jyoti Katoch, assistant professor of physics at Carnegie Mellon University, has received a prestigious early career grant from the U.S. Department of Energy (DOE). Katoch’s research focuses on understanding the properties of two-dimensional quantum materials.

The grant will allow Katoch, a condensed matter physicist, and her research group in Carnegie Mellon’s Lab for Investigating Quantum Materials, Interfaces and Devices (LIQUID) to investigate quantum materials using advanced technologies. 2D materials are the thinnest known materials. When these materials are stacked together, they form heterostructures with unique quantum properties, such as superconductivity. By changing the layers of materials, researchers can finely tune the heterostructure’s electronic and physical properties.

Under the DOE grant, Katoch will probe the spatially resolved electronic band structure of 2D quantum materials, including those made by stacking graphene and transition metal dichalcogenides, and engineer the materials’ properties by making nanoscale perturbations in superlattices and adatoms found in the materials’ heterostructures. They will do this by further developing in-operando nanoARPES, an experimental technique that combines spectroscopy and microscopy to study the band structures of quantum systems under non-equilibrium conditions.


John Keith receives NSF funding for water sterilization research

The National Science Foundation (NSF) will fund collaborative research at the University of Pittsburgh’s Swanson School of Engineering and Drexel University’s College of Engineering that could transform the way we sterilize water on demand and in larger scales. 

The project, “Collaborative Research: Regulating homogeneous and heterogeneous mechanisms in six-electron water oxidation,” will receive $473,065, with $222,789 designated for Pitt’s team. Led at Pitt by John Keith, PhD, assistant professor of chemical and petroleum engineering, the research aims to discover a simpler and less energy-intensive way to create ozone, a molecule that the U.S. Food and Drug Administration has approved for water and food sanitation since 2001.  

Dr. Keith’s research group will use computer modeling to study how water can react to form ozone in electrochemical cells.  


Mimicking nature with the aid of machine learning

Computational modeling and experimental research are used in a synergistic manner to develop and understand advanced materials in Professor Paul Leu's lab at the University of Pittsburgh Swanson School of Engineering. In collaboration with SigOpt and NETL, his team created a nanostructure glass that takes inspiration from the wings of the glasswing butterfly to create a new type of glass that is not only very clear across a wide variety of wavelengths and angles, but is also antifogging. Glass for technologies like displays, tablets, laptops,  smartphones, and solar cells need to pass light through, but could benefit from a surface that repels water, dirt, oil, and other liquids.

The team recently published a paper detailing their findings: “Creating Glasswing-Butterfly Inspired Durable Antifogging Omniphobic Supertransmissive, Superclear Nanostructured Glass Through Bayesian Learning and Optimization” in Materials Horizons. “Something significant about the nanostructured glass research, in particular, is that we partnered with SigOpt to use machine learning to reach our final product,” says Dr. Leu. “When you create something like this, you don’t start with a lot of data, and each trial takes a great deal of time. We used machine learning to suggest variables to change, and it took us fewer tries to create this material as a result.”

On the morning of July 9, the National Science Foundation announced a $10 million dollar grant to the Pittsburgh Supercomputing Center (PSC) to fund a new piece of cutting-edge hardware for the local research institutions. Known as Bridges-2, the machine, currently under construction by Hewlett Packard Enterprise, will specialize in artificial intelligence and machine learning and is scheduled to launch in the summer of 2020.


Amazon prime deal on quantum computers

If only! This headline might be a near-future reality soon enough though as a collaborative effort between UPitt professor Hrvoje Petek and a team at the University of Tsukuba has made progress towards affordable consumer quantum computers. Studying a novel process for creating coherent lattice waves inside silicon crystals using ultrashort laser pulses (shown in image), they were able to show that coherent vibrational signals could be maintained inside the samples. This research may lead to quantum computers based on existing silicon devices that can rapidly perform tasks out of the reach of even the fastest supercomputers now available.
