Helium recovery at Pitt

In 2014, in the midst of a multiyear spike in helium prices, the University of Pittsburgh poured millions of dollars into building a high-tech machine aimed at recovering the helium that its researchers used. Prices stabilized soon after, and a substantial return on its investment seemed a far-off possibility. But now, as another shortage threatens the viability of basic science research, Pitt’s machine — one of the most efficient of its kind in the world — is paying dividends. Crude helium prices sold at the U.S. Bureau of Land Management’s 2019 auction clocked in at $279.95 per million standard cubic feet, an increase of roughly 135% from the year prior.

Helium is used to maintain low-operating temperatures of medical devices such as MRI scanners and nuclear magnetic resonance spectrometers — machines that help with analysis of small molecules. Mr. Chambers, the Pitt facilities director, said the university’s recovery system has decreased its helium usage by over 60%. Yet he still remains concerned about availability, especially after an ominous call from a supplier recently warning of a “large shortage” coming in July.

Di Xiao awarded Simons Fellowship

CMU Associate Professor of Physics Di Xiao has been awarded a fellowship by the Simons Foundation. The Simons Foundation was founded in 1994 to support research in mathematics and the basic sciences. Xiao was one of nine theoretical physicists awarded fellowships by the foundation this year. The fellowship will allow Xiao to take a sabbatical from teaching for the 2019-20 academic year to focus on his research in quantum condensed matter theory on the magnetic and electric multipoles in crystalline solids.
