Contamination, adherences, deposits or even biofilms are a great problem in the processing of foodstuffs or pharmaceutical products. Surfaces exposed to these kinds of issues must have not only good non-stick properties but also high wear resistance in order to guarantee an adequate service life.
Especially suitable here are modified diamond-like carbon coatings (DLC), such as, for example, the SICON® coating developed at the Fraunhofer IST, which is a DLC coating modified with silicon and oxygen.
SICON® coatings of this kind have similarly good non-stick properties as the familiar Teflon®, but can offer a much higher wear resistance and heat resistance.
One specific example of an application of this kind of combination of wear protection and non-stick coatings is (industrial) blades.
In commercial and in particular in industrial processing not only does the non-stick aspect play a major role but so also does the wear resistance of the blades since cleaning processes and tool changes alike mean production downtimes.
Examples of blades coated in this way at the Fraunhofer IST can be viewed from April 13 – 17, 2015 at the Hannover Fair (Hall 3, Stand D26).

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
Broadband rotational spectroscopy unravels structural reshaping of isolated molecules in the gas phase to accommodate water

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
