Today's car enthusiasts have a diverse range of requirements: popular issues that concern them include safety in the vehicle, a good driving experience, a powerful engine and sophisticated technology.
If drivers want to make an impression with their vehicle, decorative elements such as coloured wheel rims, brake calipers, exhausts, footboards or bodywork and engine components are increasingly being added. In an ideal scenario, it is possible to combine decorative coatings with protection from corrosion and wear.
INM will be presenting such coatings at this year's IAA International Motor Show. It will present its results in cooperation with automotive.saarland in Hall 4.0 at Stand D27.
The coatings have glassy and glass-ceramic properties. They therefore reduce the level of corrosion and wear, susceptibility to scratching or tarnishing and other processes of oxidation on surfaces.
To complement these protective properties, depending on the choice of colour pigments, the INM production method can be used to produce the colours of red, black, green, white and blue for decorative purposes with stability at high temperatures.
These functional coatings are suitable for metallic substrates such as steel, aluminium or alloys or as a protective layer for glassy components.
"In addition to the properties which have been mentioned, our production method also opens up other possibilities," says Peter William de Oliveira, head of the Optical Materials program division. These include possible non-stick properties, a certain flexibility in the layer or also the possibility of electrical insulation as a result of the vitreousness.
The INM uses special silicates for the coatings. They are converted into a sol-gel nanocomposite in a single-step reaction. Depending on the colour pigment and the substrate, this means that surfaces can be hermetically sealed at from 200 to 800 degrees Celsius.
The thickness of these layers ranges from two to ten micrometres. Curved and flat surfaces can easily be covered with the coating in immersion chambers or spray booths.

INM conducts research and development to create new materials – for today, tomorrow and beyond. Chemists, physicists, biologists, materials scientists and engineers team up to focus on these essential questions: Which material properties are new, how can they be investigated and how can they be tailored for industrial applications in the future? Four research thrusts determine the current developments at INM: New materials for energy application, new concepts for medical surfaces, new surface materials for tribological systems and nano safety and nano bio. Research at INM is performed in three fields: Nanocomposite Technology, Interface Materials, and Bio Interfaces.
INM – Leibniz Institute for New Materials, situated in Saarbrücken, is an internationally leading centre for materials research. It is an institute of the Leibniz Association and has about 210 employees.

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...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
