Researchers from the Max Planck Institute for Polymer Research in Mainz, Germany, and the Tampere University of Technology, Finland, have found a new way of applying a structured coating for liquid repellency.
By using liquid flame spray, the method is extremely fast. Not only water but also oil drops do not adhere to these surfaces but remain spherical and bounce or roll off easily.

Depending on the magnetic configuration of the spin valve, the electrical signal is transmitted (bottom) or suppressed (top). ill./©: Joel Cramer

Magnon spintronics employs magnons instead of electrical charges for information processing. In the emerging field of magnon spintronics, researchers investigate the possibility to transport and process information by means of so-called magnon spin currents. In contrast to electrical currents, on which todays information technology is based, magnon spin currents do not conduct electrical charges but magnetic momenta.

The printed stripes make all the difference. By series connection, each square of ten stripes is capable of producing a voltage of about 8 Volt. © Fraunhofer IAP

Imagine a jacket that produces enough electricity to charge your mobile phone. Imagine a jacket that does not only reflect, but light up itself when you ride your bike in the dark. Innovative printing solutions make future happen today. The Fraunhofer Institute for Applied Polymer Research IAP presents different prototypes from photovoltaics research projects at the international exhibition and conference for the printed electronics industry LOPEC 2018 in Munich, March 13 to 15. First projects resulting from the German OLED Technology Alliance (GOTA) are being presented as well.

The test cell has been successfully implemented in research projects at Fraunhofer ISE and duplicated for project partners. Fraunhofer ISE

The Fraunhofer Institute for Solar Energy Systems ISE is presenting innovative solutions and projects on renewable energy storage and grid integration at the Energy Storage Europe, the leading international trade fair for storage in Düsseldorf, Germany from March 13-15. Fraunhofer ISE is presenting at a joint booth of the Fraunhofer Energy Alliance (Hall 8b, booth B39). Parallel to the trade fair, the 12th International Renewable Energy Storage Conference (IRES) and the 7th Energy Storage Europe Conference (ESE) are taking place.
