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

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.
This time-lapse sequence of structures reveals dynamic motions as a fundamental element in the molecular foundations of biology.
Two research teams have succeeded simultaneously in measuring the long-sought Thorium nuclear transition, which enables extremely precise nuclear clocks. TU Wien (Vienna) is part of both teams.
If you want to build the most accurate clock in the world, you need something that "ticks" very fast and extremely precise. In an atomic clock, electrons are...
Researchers from Chalmers University of Technology have demonstrated a detector made from graphene that could revolutionize the sensors used in next-generation space telescopes. The findings were recently published in the scientific journal Nature Astronomy.
Beyond superconductors, there are few materials that can fulfill the requirements needed for making ultra-sensitive and fast terahertz (THz) detectors for...
A supersolid is a state of matter that can be described in simplified terms as being solid and liquid at the same time. In recent years, extensive efforts have been devoted to the detection of this exotic quantum matter. A research team led by Tilman Pfau and Tim Langen at the 5th Institute of Physics of the University of Stuttgart has succeeded in proving experimentally that the long-sought supersolid state of matter exists. The researchers report their results in Nature magazine.
In our everyday lives, we are familiar with matter existing in three different states: solid, liquid, or gas. However, if matter is cooled down to extremely...
A team headed by Prof. Steve Albrecht from the HZB will present a new world-record tandem solar cell at EU PVSEC, the world's largest international photovoltaic and solar energy conference and exhibition, in Marseille, France on September 11, 2019. This tandem solar cell combines the semiconducting materials perovskite and CIGS and achieves a certified efficiency of 23.26 per cent. One reason for this success lies in the cell’s intermediate layer of organic molecules: they self-organise to cover even rough semiconductor surfaces. Two patents have been filed for these layers.
Perovskite-based solar cells have experienced an incredibly rapid increase in efficiency over the last ten years. The combination of perovskites with classical...
