A team of scientists from the U.S. Department of Energy’s Brookhaven National Laboratory, the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST), and the University of Oslo in Norway has provided new insight into the superconductivity of magnesium diboride (MgB2), an unusual superconductor discovered only last year. The new result appears in the June 17, 2002 issue of Physical Review Letters.
Understanding the origin of superconductivity — the ability of some materials to conduct electricity without losing energy — will help scientists improve magnetic resonance imaging (MRI) and the efficiency of electric power transmission, and build smaller, more powerful electronic devices.
Scientists usually assume that superconductivity arises from electrons coupling in pairs,” said Yimei Zhu, a physicist at Brookhaven’s Advanced Electron Microscopy Facility and lead author of the study. “Though this is the case for most superconductors, it has not been shown yet how electrons contribute to superconductivity in magnesium diboride. So we decided to look more closely at this material’s electronic structure.”

(Re)solving the jet/cocoon riddle of a gravitational wave event
22.02.2019 | Max-Planck-Institut für Radioastronomie
An international research team including astronomers from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has combined radio telescopes from five continents to prove the existence of a narrow stream of material, a so-called jet, emerging from the only gravitational wave event involving two neutron stars observed so far. With its high sensitivity and excellent performance, the 100-m radio telescope in Effelsberg played an important role in the observations.
In August 2017, two neutron stars were observed colliding, producing gravitational waves that were detected by the American LIGO and European Virgo detectors....
Up to now, OLEDs have been used exclusively as a novel lighting technology for use in luminaires and lamps. However, flexible organic technology can offer much more: as an active lighting surface, it can be combined with a wide variety of materials, not just to modify but to revolutionize the functionality and design of countless existing products. To exemplify this, the Fraunhofer FEP together with the company EMDE development of light GmbH will be presenting hybrid flexible OLEDs integrated into textile designs within the EU-funded project PI-SCALE for the first time at LOPEC (March 19-21, 2019 in Munich, Germany) as examples of some of the many possible applications.
The Fraunhofer FEP, a provider of research and development services in the field of organic electronics, has long been involved in the development of...
For the first time, an international team of scientists based in Regensburg, Germany, has recorded the orbitals of single molecules in different charge states in a novel type of microscopy. The research findings are published under the title “Mapping orbital changes upon electron transfer with tunneling microscopy on insulators” in the prestigious journal “Nature”.
The building blocks of matter surrounding us are atoms and molecules. The properties of that matter, however, are often not set by these building blocks...
