Coatings used to protect the exposed wooden parts of buildings have to withstand all kinds of weather. To avoid over-frequent renovation, architects, builders and house-owners are advised to look for a reliable quality label. The relevant European standard is being revised.
A weather-beaten mountain chalet might look charming – but assaults by heat and cold, rain and sunshine, will eventually destroy even highly weather-resistant timber like larch. Outdoor paint or varnish is expected to prolong the life of most types of timber, and of course stand up to years of exposure to the elements.
If the paint begins to flake sooner than the house-owner anticipated, in the worst case the paint manufacturer is likely to find himself faced with a claim for damages. House painters, producers of garden furniture, and architects are not willing to be left carrying the blame. That is why it is advisable to look for a quality label when choosing the appropriate product.

Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
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...
