The energy is not stored in the form of increased heat but in the form of a chemical state
In Germany, 55 percent of final energy consumption goes towards heating and cooling. However, a lot of heat dissipates unused because it is not generated as and when required. Thermal storage using zeolite material allows heat to be stored for long periods of time without losing any. Fraunhofer ...
New ways to modify the structure of aluminium alloys for improving their performance
Currently, low-alloy aluminium is widely used in electrical engineering and machine building. At the same time, it should be noted that modern electrical engineering places very high and in some cases mutually exclusive requirements to aluminium alloys. For example, conductive aluminium alloys ...
Scientists develop self-cleaning aluminium surface
A project team of Technische Universität Dresden and the Fraunhofer Institute for Material and Beam Technology IWS structured an aluminium plate with a laser process in such a way that water droplets no longer adhere and dirt particles can be removed from the surface - completely without chemical ...
In the battery of the future, solids will replace the currently used electrolyte solutions. A team of scientists at LMU has now developed a series of new sodium ion conductors. The secret of the best material in the series lies in the exact mixing of the ingredients. The days of conventional ...
A Chinese-German research cooperation involving the University of Augsburg has demonstrated properties in a metal that cannot be explained by the standard theory. The results were obtained on a special metallic compound with unusual magnetic characteristics – scientists call it mag-netic ...
Heterometallic copper-aluminum super atom discovered
On the outside, the cluster made of 55 copper and aluminum atoms looks like a crystal, but chemically it has the properties of an atom. The heterometallic superatom which chemists of the Technical University of Munich (TUM) have created provides the prerequisites for developing new, more ...
All 60 electrolysis cells are now in operation at the Karmøy technology pilot, where Hydro aims to industrialize the world's most climate and energy efficient aluminium electrolysis technology. "Our aim is to be the global leader in technology and innovation in our industry, and the Karmøy pilot ...
A new conductor material and a new electrode material could pave the way for inexpensive batteries and therefore the large-scale storage of renewable energies. The energy transition depends on technologies that allow the inexpensive temporary storage of electricity from renewable sources. A ...
With their insensitivity to decoherence what are known as Majorana particles could become stable building blocks of a quantum computer. The problem is that they only occur under very special circumstances. Now researchers at Chalmers University of Technology have succeeded in manufacturing a ...
New material increases efficiency
Electronic devices such as computers generate heat that mostly goes to waste. Physicists at Bielefeld University have found a way to use this energy: They apply the heat to generate magnetic signals known as 'spin currents'. In future, these signals could replace some of the electrical current in ...
