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 assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.
The most complete assessment ever of statistical uncertainty within the GISS Surface Temperature Analysis (GISTEMP) data product shows that the annual values...
Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.
The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
