The EUREKA E! 3418 LIG-HT project is set to bring the sun into the heart of the Austrian Tyrol town of Rattenberg in the depths of winter. A combination of heliotstats – mirrors that track the sun – and optical concentrators would make it possible to light up locations within the town that lies totally in the shadow of a 900-m high mountain for over three months of the year. The benefits would be psychological, economic and environmental.
Rattenberg was built just north of the Rat Mountain for defensive reasons in the Middle Ages. But the height of the mountain means that local inhabitants must seek sun outside their town during the cold winter months from November to mid February. The depressive effect of this lack of natural light has led to a steady reduction in the population over recent years.
“We have worked with the town authorities on various street and monument lighting projects,” explains Wilfried Pohl of Austrian project leader Bartenbach LichtLabor. This lighting design bureau has long specialised in the use of natural light to illuminate windowless offices and underground areas. “Use of natural light not only saves electrical energy but also raises the environmental quality of the areas being illuminated. This led to the idea of using optical reflector technology to provide sunny spots within the town.”

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
