Thanks to intensive research in the past three decades, organic light-emitting diodes (OLEDs) have been steadily conquering the electronics market - from OLED mobile phone displays to roll-out television screens, the list of applications is long.
Current OLED research focuses in particular on improving the performance of white OLEDs for lighting elements such as ceiling or car interior lighting. These components are subject to much stricter requirements in terms of stability, angular emission and power efficiency.

In a joint project with the Technische Universität Braunschweig, researchers from the Fraunhofer WKI have developed an innovative building element for the construction industry: a sandwich element with a wood-foam core and a thin cover layer of textile-reinforced concrete. It can be used, for example, as a lightweight curtain-wall element or in interior fittings. The high-performance wood foam requires no artificial binding agents and can be produced from regionally available wood residues. Through the utilization of wood foam instead of conventional foam based on petrochemicals, the proportion of particularly sustainable construction materials in buildings can be increased.

Physicists at the University of Innsbruck are proposing a new model that could demonstrate the supremacy of quantum computers over classical supercomputers in solving optimization problems. In a recent paper, they demonstrate that just a few quantum particles would be sufficient to solve the mathematically difficult N-queens problem in chess even for large chess boards.

An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".
