Nano coatings impart new properties to surfaces, they become lubricated and repel dirt. They are used in ship-building so that algae and mussels cannot stick to surfaces and they are used on aircraft to prevent the attachment of ice crystals. Building facades and roof tiles remain clean and presentable for longer.

Infrared emitters dry nano lacquers and other functional coatings reliably without impairment of their special properties. At the PaintExpo exhibition in Karlsruhe, Heraeus Noblelight is showing infrared emitters which can be precisely matched to the properties of the coating system.
Water drips off shower walls, roof tiles repel dirt, facades stay glossy, frequently, all this is the work of coatings with functional properties. For building facades or roofs a dirt-repellant coating is very practical, in healthcare it helps to keep rooms cleaner and perfectly hygienic. With ships and aircraft, the repellent effect can save energy and can even be of vital importance. Algae or shellfish which cling to ships, significantly affect propulsion and ice crystals on aircraft are a safety risk.
Coatings with functional properties, many of which are nano coatings, are also used on machine and engine parts such as linkage shafts of ships’ propulsion systems, which are exposed to salt water or other unfavorable weather influences.
However, all protective coatings must be applied and dried very homogenously so that their functional property is effective evenly and reliably over the complete component.
This means that the coating must be sprayed on in very thin layers, which are then dried quickly without destroying the special properties of the coating. Infrared emitters transfer heat efficiently without contact, with the aid of electromagnetic waves, which generate the heat primarily in the material. As a result, the adhesion of disruptive particles in the sensitive coating during drying is minimized.
Infrared emitters offer very fast reaction times. Shortwave and Carbon emitters from Heraeus react within one to three seconds. This ensures that heating is controllable and, combined with temperature control, helps to eliminate overheating of materials.
Rapid change-over of different types of coating having different burn-in temperatures are possible. And it also saves energy when the heat source needs to be switched on only when it is needed.
Heraeus Noblelight offers the spectrum of infrared heat from near infrared (NIR) to medium wave carbon infrared CIR, carries out tests with the materials in question and advises on the selection of the optimum emitters for the specific process.
Heraeus has more than 40 years experience with infrared emitters, both for end-users and for large OEMs and carries out practical tests with customer own materials in its own application centres to establish optimum process solutions.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
