In their latest article, Jeremy Levy and his group put forward compelling experimental evidence of the role of surface chemistry on conductivity in complex oxides heterostructures. 

This work, published in Nature Communications on February 10, 2016 illustrates how the conductivity of the 2DEG layer in LAO/STO can be modulated using solvent immersion and illumination. 


Reflections on Nano and Femto Imaging

"Scanning near-field optical microscopy combined with pump–probe spectroscopy can resolve ultrafast dynamics at the nanoscale."

In this short article, Hrvoje Petek reflects on a new technique that combines the nanometre resolution of near-field microscopy with the femtosecond resolution of pump–probe spectroscopy. This technique has been developed by Markus Raschke and colleagues at the University of Colorado at Boulder and submitted in the present issue of Nature Nanotechnology.

PQI faculty Linda A. Peteanu has been named acting head of Carnegie Mellon University's Department of Chemistry, effective January 1, 2016.

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. A current research focus 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.


Ted Corcovilos Develops Portable Device to Test for Lead in Water

Pittsburgh Water and Sewer Authority officials will re-examine the treatment used to limit lead in customers' water as levels approach a federal warning threshold and a drinking water crisis in Flint, Mich., intensifies worries across the country. Lead can cause irreversible brain damage in children. The Centers for Disease Control and Prevention and the Environmental Protection Agency say there is no safe level of lead exposure for children.

A team of local researchers includig PQI faculty Ted Corcovilos has developed a device to test for the presence of lead in water. This portable device is called Leadglow and is powered by two nine-volt batteries. Part of it was made on a 3D printer.
