A new way to manufacture a low-cost superconducting material should lead to cheaper magnetic resonance imaging machines and other energy-efficient applications, say Los Alamos National Laboratory scientists.
Hot isostatic pressing of wires made of magnesium diboride, or MgB2, significantly increased the amount of electrical current the wires can carry without electrical resistance. Wires made from MgB2 would reduce the costs of such products as MRIs and electrical generators, say the researchers: Adriana Serquis, Leonardo Civale, Xiaozhou Liao, J. Yates Coulter, Duncan Hammon, Yuntian Zhu, Dean Peterson and Fred Mueller from Los Alamos Superconductivity Technology Center; and Vitali Nesterenko from the University of California, San Diego. They presented their findings on Dec. 3 at the Materials Research Society meeting in Boston.
"This material will likely serve as a bridge to the energy future in a variety of cost-driven applications, because potentially this is the lowest-cost superconducting material," said Peterson, who leads the Los Alamos Center. "Theres nothing to prevent making this material into wires that are many miles long."

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
