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?

DNA molecules that follow specific instructions could offer more precise molecular control of synthetic chemical systems, a discovery that opens the door for engineers to create molecular machines with new and complex behaviors.
Researchers have created chemical amplifiers and a chemical oscillator using a systematic method that has the potential to embed sophisticated circuit...
MPQ scientists achieve long storage times for photonic quantum bits which break the lower bound for direct teleportation in a global quantum network.
Concerning the development of quantum memories for the realization of global quantum networks, scientists of the Quantum Dynamics Division led by Professor...
Researchers have developed a water cloaking concept based on electromagnetic forces that could eliminate an object's wake, greatly reducing its drag while...
Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
