Shape memory achieved for nano-sized objects

Alloys that can return to their original structure after being deformed have a so-called shape memory. This phenomenon and the resulting forces are used in many mechanical actuating systems, for example in generators or hydraulic ...

Strong microwave magnetic fields for more efficient plasmas

Hot gases composed of metal ions and electrons, called plasmas, are widely used in many manufacturing processes, chemical synthesis, and metal extraction from ores and welding. A collaborative research group from Tohoku University ...

Now on the molecular scale: Electric motors

Electric vehicles, powered by macroscopic electric motors, are increasingly prevalent on our streets and highways. These quiet and eco-friendly machines got their start nearly 200 years ago when physicists took the first ...

Decoding mega magnetic explosions outside the solar system

Neutron stars and black holes may be stellar corpses, but they are among the most active celestial objects. They produce some of the highest-energy radiation ever observed, and scientists have long puzzled over the physics ...
