In 2011, the German plastics processing industry generated revenues of 55.9 billion euros, up 15 percent on the previous year's figure. Approximately one third of these revenues were generated by the packaging industry, which makes more than half of its sales from extruded packaging systems.

As demand increases, so too does the complexity of the plastic packaging solutions requested by customers – and this challenge is pushing manufacturers to place more and more emphasis on functionalizing packaging films by offering complex layer structures. For example, adding a layer of ethylene vinyl alcohol (EVOH) copolymers creates a diffusion barrier against oxygen and water vapor which ensures that food products keep fresh longer. Currently, the minimum thickness of individual functional layers lies between 2 - 100 µm. In order to ensure they meet the minimum thickness requirements, plastics manufacturers apply more of the expensive functional material than is strictly necessary. As a result, EVOH and comparable plastics such as polyamide (PA) have come to represent a significant cost factor.Guaranteeing quality and reducing material waste

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.
