Mobile phone battery chargers also use power when the mobile phones are not being charged. The majority of power is wasted if the battery charger remains connected to the mains. Most consumers do not realise this and keep their chargers connected to the socket all the time.
It would be good to pull the battery charger from the socket. It would be still better to build chargers in such a way that they use no or a negligible amount of electricity after completion of the battery loading process. Some manufacturers aim at achieving this goal.
In order to establish a general rule for cost reduction, energy efficiency and climate protection, the European Union published the Ecodesign Directive. This directive regulates power consumption for energy-using products. In Germany the directive is implemented by the Energy-using Products Act (EuPA).
The BAM Federal Institute for Materials Research and Testing as the commissioned body is responsible for providing information on this topic which BAM will be doing at the international radio exhibition. BAM experts will answer such questions as:o Which devices use particularly large amounts of energy?

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.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
