Further improvement of qubit lifetime for quantum computers

Thu, 08 Dec 2016 00:00:00 EST

(Forschungszentrum Juelich) An international team of scientists has succeeded in making further improvements to the lifetime of superconducting quantum circuits.

Ultrathin protective layer brings quite a bit more stability to perovskite solar cell

Mon, 05 Dec 2016 00:00:00 EST

(Eindhoven University of Technology) The addition of a few nanometers of a thin layer of aluminum oxide protects a perovskite solar cell against humidity -- still a major stumbling block to the commercial application of this new type of solar cell. A surprising bonus is a yield boost of 3 percent. These are the findings of researchers at Eindhoven University of Technology (TU/e) and research institute ECN, part of the Solliance collective, published today in the journal Energy and Environmental Science.



Why friction depends on the number of layers

Mon, 05 Dec 2016 00:00:00 EST

(Karlsruher Institut für Technologie (KIT) ) Based on simulations, friction properties of the two-dimensional carbon graphene were studied by scientists of Karlsruhe Institute of Technology (KIT) and the Fraunhofer Institute for Mechanics of Materials IWM with scientists in China and the USA. In contact with monolayer graphene, friction is higher than with multi-layered graphene or graphite; friction force increases for continued sliding. The scientists attribute this to the real contact area and the evolving quality of frictional contact.
