A scientific colloquium was held today to mark the official opening in Bremen of the new 90 cubic meter ice laboratory with integrated icing wind tunnel.
The Paint/Lacquer Technology Department at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM has thus reached a further milestone for testing anti-icing coatings and innovative deicing technologies.
Fraunhofer IFAM researchers and their project partners from industry and R&D organizations will now be able to test anti-icing systems under realistic conditions at temperatures down to minus 30 degrees Celsius and at wind speeds of up to 350 kilometers per hour.
Preventing ice forming on surfaces is a major challenge. For aircraft, ships, rail vehicles, cars, air-conditioning systems, refrigeration units, and wind turbines – ice formation often endangers safety and also incurs high costs.
Intensive R&D is underway to develop ever more effective technologies for preventing the formation and adhesive of ice on technical surfaces. Fraunhofer IFAM is investigating a variety of solution-oriented approaches and for minimizing ice formation.
These include, for example, heatable coatings and their integration into a total coating concept. The heatable coatings are suitable for all uses and can be applied using conventional spraying methods, meaning that even components with very complex geometry can be rapidly and efficiently coated.
Highly promising results have also been obtained for hydrophobic, namely water-repelling, coatings that make ice adhesion more difficult.
Nanostructured surfaces and the direct integration of freezing point depressors into the coatings themselves are other anti-icing strategies that are being pursued.
All these anti-icing concepts are undergoing thorough testing. The icing wind tunnel is equipped with special control and monitoring equipment: To get defined ice formation the water injection and air humidity can be precisely controlled.
An infrared camera simultaneously records the icing process and the heat distribution on the surfaces. The new test laboratory with icing wind tunnel will facilitate ongoing and future R&D projects and will be used for fundamental research work, ice adhesion tests, and the investigation of surface icing by snow, rain, and supercooled water droplets.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
