This work is being undertaken in an international project with European and Japanese partners. The objective is to develop an integrated system comprising three synergistic components: Active de-icing technology, functional coatings which assist the de-icing function, and sensor technology which not only monitors the icing in real-time but also the de-icing.

The surfaces of aircraft are prone to icing during flights due to the fact that they are exposed to extremely low temperatures (down to -50 degrees Celsius at altitudes of up to 10,000 meters) and also water in the atmosphere, for example in clouds and precipitation.The formation of ice, particularly on the wings, can lead to enormous problems due to its adverse effect on the aerodynamics and due to its weight. Besides causing higher fuel consumption and greater CO2 emissions, the ice is also a risk to the safety of an aircraft: e. g. for 1998 to 2007, the Federal Aviation Administration (FAA) in the USA recorded in its database a total of 886 incidents related to icing (G. L. Dillingham, AVIATION SAFETY – Preliminary Information on Aircraft Icing and Winter Operations. United States Government Accountability Office. Testimony before the Subcommittee on Aviation, Committee on Transportation and Infrastructure, House of Representatives (GAO-10-441T, February 2010)).
The project is being funded by the European Commission and the Japanese Ministry of Economy, Trade and Industry (METI). The Fraunhofer IFAM is leading the scientific work and coordinating the project.Partners of the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM in the JEDI ACE project are

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
