It’s a familiar scenario – limescale in the electric kettle and coffee machine or water stains on the taps, these are problems which are not yet soluble in the household. The situation is however somewhat different in industrial systems: it is precisely in large-scale production with liquid media that so-called ‘fouling’ is often the cause of expensive cleaning cycles and thus of longer machine downtimes.
For example, the milk pasteurization line is stopped once again and cleaned after just one operating cycle because, for example, milk proteins have formed deposits in the pipes, boilers or heat exchangers of the equipment used.
A further disadvantage of contamination by crystallization, corrosion or chemical and biological reactions is a considerably higher level of energy consumption during the production cycle.
At the Fraunhofer Institute for Surface Engineering and Thin Films IST, technical solutions and coatings have been developed for different areas of application by which fouling effects of this kind can be drastically reduced.
Of particular note here is the fact that the coatings can be tailored to specific requirements, and it is precisely in the chemical, pharmaceutical and foodstuffs industries that this can yield improved productivity and significant cost reductions.
The Fraunhofer IST will give an overview of the latest antifouling coatings at the Hannover Surface Technology fair from April 13 – 17, 2015 (Hall 3, Stand D26).

A Swedish-German team of researchers has cleared up a key process for the artificial production of silk. With the help of the intense X-rays from DESY's...
For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Yersiniae cause severe intestinal infections. Studies using Yersinia pseudotuberculosis as a model organism aim to elucidate the infection mechanisms of these...
Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
