Theoretical Chemistry Research Looks to Reduce Side Effects of Medications for Depression, Addiction, Disease
A research team including PQI faculty Dr. Jeffry D. Madura is attempting to unravel the regulation of dopamine, which leads to happiness. By mapping how these critical neurotransmitters are controlled, Madura and colleagues are trying to better understand the function and structure of the proteins that modulate the receptor/transporter processes of dopamine and serotonin as well as amphetamines and cocaine. The group already has identified a compound as a potential new class of serotonin inhibitors, which would work with the proteins that transport the hormone.
Their initial findings were reported in the Biophysical Journal, with their detailed analysis expected to be published soon.
NASA’s Mars Rover Curiosity fired its first laser beam in August, blasting a space rock at more than one million watts per shot to determine whether the red planet could be habitable. The method, called laser-induced breakdown spectroscopy (LIBS), is used to detect not only the composition of space-related soils but also an array of foreign materials. Now, with the help of a $1.12 million grant from the U.S. Department of Defense, PQI faculty Kevin Chen will build upon the LIBS technique and related instruments to dramatically improve the detection sensitivity of the technology for substances of interest to Homeland Security.
PQI faculty Andrew Daley and his colleagues have proposed a scheme for the measurement of entanglement in a system of cold atoms in an optical lattice. Entanglement is an important theoretical concept, but was previously thought to be difficult to measure in microscopic many-particle systems. They tackle the problem by asking how one might track the changes in entanglement in a nonequilibrium many-body system.
Jung-Kun Lee has received a National Science Foundation grant for his research into solar cell energy conversion. The grant, Solid State Dye Sensitized Solar Cells Using Tunable Surface Plasmons of Core-Shell Particles, is $290,724 over three years. 
With the advent of semiconductor transistors—invented in 1947 as a replacement for bulky and inefficient vacuum tubes—has come the consistent demand for faster, more energy-efficient technologies. To fill this need, researchers at PQI are proposing a new spin on an old method: a switch from the use of silicon electronics back to vacuums as a medium for electron transport—exhibiting a significant paradigm shift in electronics. Their findings were published in 
PQI faculty Paul W. Leu is a recipient of the Ralph E. Powe Junior Faculty Achievement Award. The awards provide seed money for research by junior faculty at Oak Ridge Associated Universities (ORAU) member institutions. These awards are intended to enrich the research and professional growth of young faculty and result in new funding opportunities. 
The Quantum Information Science and Technology (QIST) Summit , hosted by the Department of Energy's Brookhaven National Lab, took place on October 7-8th and connected industry, governmental, and academic experts to discuss six broad themes in panel sessions. PQI...
The Chancellor's Distinguished Research Award annually recognizes outstanding scholarly accomplishments of members of the University of Pittsburgh's faculty. Junior Scholar Awardees include faculty members who, by virtue of the exceptional quality of their early contributions, have demonstrated great potential...
A research team led by PQI faculty Jeremy Levy has discovered electrons that can "swing dance". This unique electronic behavior can potentially lead to new families of quantum devices. Superconductors, materials that permit electrical current to flow without...
