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?

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
