These monthly highlights, selected by MagLab Director Greg Boebinger, represent the most promising and cutting-edge research underway in the lab’s seven user facilities.
In this study, researchers added a low concentration of the endohedral metallofullerene (EMF) Gd2@C79N to DNP samples, finding that 1H and 13C enhancements increased by 40% and 50%, respectively, at 5 teslas and 1.2 Kelvin.
MagLab scientists and engineers have developed a special coating on Bi-2212 superconducting wire for electrical insulation in superconducting magnets that will enable the wire to be used in ultra-high field nuclear magnetic resonance magnets.
In the 14 years since its discovery, graphene has amazed scientists around the world with both the ground-breaking physics and technological potential it displays. Recently, scientists from Penn State University added to graphene's gallery of impressive scientific achievements and constructed a map that will aid future exploration of this material. This work is emblematic of the large number of university-based materials research efforts that use the MagLab to explore the frontiers of science.
Analogous to the unique spectral fingerprint of any atom or molecule, researchers have measured the spectrum of optical excitations in monolayer tungsten diselenide (WSe2), which is a member of a new family of ultrathin semiconductors that are just one atomic layer thick.
Protein oxidative damage is a common occurrence in a number of diseases, including cancer, neurodegenerative, and cardiovascular disease. Yet, little is known about its contribution to these illnesses. We developed a new technique, utilizing an infrared laser in combination with a mass spectrometer, to selectively identify sites of oxidation in complex protein mixtures. This sensitive and rapid platform may outperform current techniques and thus shed light on the involvement of oxidative damage in each of these diseases.
This high-field EPR study of the H-Mn2+ content in the bacterium Deinococcus Radiodurans provides the strongest known biological indicator of cellular ionizing radiation resistance between and within the three domains of the tree of life, with potential applications including optimization of radiotherapy.
Decades ago a mechanism was proposed that described a quantum phase transition to an insulating ground state from a semi-metal (excitonic insulator, or EI) using very similar mechanics to those found in the BCS description of superconductivity. The discovery of this transition to an EI in InAs/GaSb quantum wells is striking not only for the long-sought experimental realization of important physics, but also the presence of recently proposed topological behavior.
