Conserving a Valuable Resource: System Will Recover Helium for Physics Lab Use

Pitt’s new physics department helium recovery system will put the campus at the forefront of U.S. university efforts to conserve the finite supply of this increasingly expensive laboratory gas. With U.S. helium reserves being sold off and prices rising, Pitt … Continue reading

3He NMR Studies on Helium–pyrrole, Helium–indole, and Helium–carbazole Systems

The 3He nuclear magnetic shieldings were calculated for free helium atom and He–pyrrole, He–indole, and He–carbazole complexes. Several levels of theory, including Hartree–Fock (HF), Second-order Møller-Plesset Perturbation Theory (MP2), and Density Functional Theory (DFT) (VSXC, M062X, APFD, BHandHLYP, and mPW1PW91), … Continue reading

Good Results Obtained With a Novel Technology to Produce Large-scale Neutron Converters

A European collaboration is developing an atmospheric plasma deposition system to produce Boron-10 layers to cope with the Hellium-3 shortage. Helium-3 is widely used in neutron detectors worldwide. However, due to a 3He shortage that caused its price to rise, … Continue reading
