Spotless surfaces are of prime importance in the plastics and metal processing industries, as dust and dirt can impair the function and adhesive properties of parts. A portable measuring device, the KombiSens, can detect both types of contamination.
Greasy fingerprints on wineglasses, ketchup on the table, crumbs on the floor – anyone with a clean disposition would be disgusted. But spotless surfaces are not the prerogative of housework maniacs; they are essential in numerous sectors of industry such as car manufacturing or metal processing, where dirt can have an adverse affect on gluing and painting processes or impair a component’s function.
When manufacturers are planning to coat a surface, they carry out regular spot checks to determine how clean their parts are. Many of these analysis methods fail to reveal defective cleaning until some time has elapsed – and meanwhile production has continued with the faulty workpieces. Researchers at the Fraunhofer Institute for Manufacturing Engineering and Automation IPA in Stuttgart have developed an easy-to-use test device for checking cleanness during the production process. KombiSens detects both dust and grease on surfaces.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
