Researchers have demonstrated an effective invisibility cloak that is thin, scalable and adaptive to different types and sizes of objects. Professor George Eleftheriades and PhD student Michael Selvanayagam have designed and tested a new approach to cloaking—by surrounding an object with small antennas that collectively radiate an electromagnetic field. The radiated field cancels out any …
A leading indicator of the OECD economy, which is designed to anticipate turning points in economic activity relative to trend, increased 0.07 percent sequentially to 100.7 in September, continuing the upward trend seen in recent months. Year-on-year, the index moved up 0.97 percent. The sub-indicator for Japan points to economic growth above trend, and the …
Bi-2212 is the only cuprate superconductor that can be made in round wire with high critical current density Jc; however, to date, its use in superconducting magnets is restricted because gas bubbles form during heat treatment, causing wire expansion, leakage and superconducting filament dedensification that greatly reduces Jc in coil length wires. This year we …
A University of Manchester team lead by Nobel laureates Professor Andre Geim and Professor Konstantin Novoselov has literally opened a third dimension in graphene research. Their research shows a transistor that may prove the missing link for graphene to become the next silicon. Graphene – one atomic plane of carbon – is a remarkable material …
