Siemens Automation and Drives (A&D) presents new electronic components in the Delta switches and socket outlets range for the retrofit market in the area of lighting and shutters. The new products include universal dimmer and shutter control inserts, conventional and wireless operator pushbuttons, and a battery-operated wall-mounted transmitter.
The "sys universal dimmer insert" is suitable for all types of lighting to 420 watts/volt-ampere connected load. The dimmer can be easily retrofitted with two-wire connections. It is characterized by a lamp-saving soft start and can be programmed to switch on to a predefined brightness value, and also features electronic overtemperature and short-circuit protection.
With the "sys shutter control insert", shutters and roller shutter motors can be controlled up to a connected load of 1,000 volt-amperes. Group and central controllers can be implemented by combining several shutter control inserts using the extension unit inputs. As well as enhancements such as 24-hour automatic operation in conjunction with the Delta "wave shutter" pushbutton, the sys shutter control insert offers a "wind alarm" safety function if a wind sensor is connected to the OPEN extension unit input.

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.
