Linda A. Peteanu has been named head of Carnegie Mellon University's Department of Chemistry. She has served as acting head since January 2016 and succeeds Hyung Kim, who stepped down from the position in the fall of 2015 after serving 14 years as department head. A member of the Carnegie Mellon faculty since 1993, Peteanu is well known for her expertise in applying fluorescence-based methods, including microscopy and electric-field effects, to condensed-phase systems. One focus of her research involves measuring the morphology and electronic properties of molecules used to make light emitting diodes (OLEDs) and photovoltaic cells. Peteanu also applies fluorescence-based methods to the study of nucleic acids as a member of Carnegie Mellon’s Center for Nucleic Acids Science and Technology.

National Science Foundation (NSF) has made a $4.8M award to the University of Pittsburgh under the Partnership for International Research and Education (PIRE) program. Sergey Frolov will be the Director of new PIRE.  Hrvoje Petek, Michael Hatridge and David Pekker are other PQI co-PIs for this project. The duration of the program is 5 years.

This PIRE will establish a multidisciplinary partnership between universities, research centers and corporations in the U.S. and France, led by the University of Pittsburgh. The aim of the partnership is the discovery and investigation of materials that hold exceptional promise for fundamental quantum physics and quantum device engineering. In particular, the focus will be on hybrid materials which combine disparate materials kinds, such as semiconductors and superconductors, in a single structure.

Renowned physicist Scott Dodelson has been named the head of the Department of Physics in Carnegie Mellon University’s Mellon College of Science.Dodelson conducts research at the interface between particle physics and cosmology, examining the phenomena of dark energy, dark matter, inflation and cosmological neutrinos.   
Under Dodelson’s leadership, the physics department will partner with other departments within the Mellon College of Science through a new theory center and continue to collaborate with colleagues in statistics, computer science, and engineering. Dodelson also hopes to increase the department’s partnerships with other universities and research initiatives worldwide and bring physics to the community through outreach programs.

 


Venkat Viswanathan Remains Skeptical of Tesla's Self-Driving Trucks

When will we see electric trucks appear on major roadways? Potentially in September. Tesla is currently developing driverless, long-haul electric semi-trucks that can move in “platoons,” or closely knit packs. But some scientists, like Venkat Viswanathan, doubt that Tesla can fulfill its promises. According to Viswanathan, electric trucks are not economically feasible yet because they would require massive batteries to power their long distance road-trips across the country. “Your cargo [would] essentially become the battery,” he says in an article for the New York Times. And because of that, there would be little room to carry goods.

 


Giannis Mpourmpakis and His Colleagues Revealed the Mystery Behind Formation of Metal Nano-particles at Specific Sizes

Nature Communications, co-authored by Giannis Mpourmpakis, and PhD candidate Michael Taylor, offers a possible way to unravel these mysteries, with the help of computer simulations. “In applying our new theory, we aim to accelerate discovery and application,” said Mpourmpakis. From molecular carriers for targeted drug delivery to systems for energy generation and storage to solar cells, this research could help.

The Charles E. Kaufman Foundation, a supporting organization of The Pittsburgh Foundation, has awarded eight grants totaling $1.8 million to support research at Carnegie Mellon University, the University of Pittsburgh, The Pennsylvania State University, Swarthmore College and University of Pennsylvania.

The Kaufman Scientific Advisory Board received 229 letters of intent from 30 academic institutions seeking funding in two categories: New Investigators and New Initiatives.

Noa Marom won a New Investigators Award, i.e., a grant of $150,000 for two years ($75,000 per year), for research on “Singlet Fission: Deriving Fundamental Insights from Computation.”

Michael Hatridge and Roger Mong won a New Initiatives Award, i.e., a grant of $300,000 for two years ($150,000 per year) for research on “Protecting Quantum Wires for Quantum Computing.”

Chandralekha Singh was one of the two team leaders of the US delegation to the 6th International conference on Women in Physics (ICWIP) in Birmingham, UK, in July 2017. She is also a co-editor of the American Institute of Physics Proceedings for this ICWIP 2017 conference to be published in 2018. This picture of Dr. Singh is with Malala Yousafzai, a Nobel peace prize winner, who was a presenter at the conference and Shamima Choudhury, a Physicist from Bangladesh. 


Computational Study of Ni-Catalyzed C−H Functionalization: Factors That Control the Competition of Oxidative Addition and Radical Pathways

  • By Aude Marjolin
  • 2 August 2017

To guide the development of a more diverse set of Ni-catalyzed C−H bond functionalizations, a thorough understanding of the mechanisms, reactivity, and selectivity of these reactions is required. Peng Liu and his student Humair Omer have undertaken a computational study of the functionalization of the C−H bonds in molecules that contain the N,N-bidentate directing group with Ni catalyst and various coupling  partners, e.g. phenyl iodide (Ph−I), which has been published in the July 26, 2017 issue of the Journal of the American Chemical Society.


Uncovering the Connection Between Negative Stiffness and Magnetic Domain Walls

  • By Aude Marjolin
  • 19 July 2017

Nature doesn't like having interfaces—this is why bubbles like to be round, and the surface of a pond settles to flat as long as it's not disturbed. These trends minimize the total amount of interface (or surface) that is present. As an exception to this behavior, certain materials are known to have a property, called negative stiffness, where the interface prefers to become distorted, or wavy, even without any external stimulation. Interfaces with negative stiffness have been considered in crystals before, but the characteristic has now also been found in modern magnetism.


The Center for Research Computing Acquires New, Powerful Computing Systems

The new Center for Research Computing (CRC), formerly known as the Center for Simulation and Modeling (SaM), is among the first in the nation to have access to Intel’s powerful new computing systems. The system will dramatically increase the speed of computation available to researchers through Pitt’s Center for Research Computing, said Ralph Roskies, associate vice provost for research computing.
