Electrical steel: Strong magnetic fields due to sharp tools
Electrical steel: Strong magnetic fields due to sharp tools
Research news In an electric drive, magnetic fields have to be created in order to transform electric energy into kinetic energy. The magnetic properties of the motor's main components, referred to as electrical steel sheets, are the decisive factor in the efficiency of the electric motor. Scientists at the Technical University of Munich (TUM) have investigated the way these steel sheets are processed and have concluded that using blunt cutting tools deteriorates the magnetic properties of the steel sheets significantly.

Physicists create new form of light
Physicists create new form of light
Try a quick experiment: Take two flashlights into a dark room and shine them so that their light beams cross. Notice anything peculiar? The rather anticlimactic answer is, probably not. That's because the individual photons that make up light do not interact. Instead, they simply pass each other by, like indifferent spirits in the night.

Sinfonia ai funghi
Sinfonia ai funghi
Do violins made of wood that had been treated with fungi sound the same as a fine, antique instrument? Acoustics experts at Empa are currently studying the body and soul of instruments made of "mycowood". Precision structure-borne sound measurements and psycho-acoustic tests with volunteers should reveal whether a fungal treatment can really improve an instrument.

Fingerprints of quantum entanglement
Fingerprints of quantum entanglement
Quantum entanglement is a key feature of a quantum computer. Yet, how can we verify that a quantum computer indeed incorporates a large-scale entanglement? Using conventional methods is hard since they require a large number of repeated measurements. Aleksandra Dimić from the University of Belgrade and Borivoje Dakić from the Austrian Academy of Sciences and the University of Vienna have developed a novel method where in many cases even a single experimental run suffices to prove the presence of entanglement.

Novel exciton interactions in carbon nanotubes
Novel exciton interactions in carbon nanotubes
In the study, a collaborative research team showed that Raman spectroscopy (a form of light scattering) can provide more extensive characterization of intertube excitons. Observing this behavior in carbon nanotubes suggests there is potential to detect and control a similar response in more complex, multi-layered semiconductor and semiconductor-metal heterostructures.

Imaging at Paul Scherrer Intitute helps to increase production at ABB site in Aaargau
The ABB facility in Wettingen, Aargau, got practical recommendations on increasing output in the manufacture of ceramic components. The ceramics in question are voltage-dependent resistors used in overvoltage protectors - a kind of lightning protection system - for example, in electrical transmission lines.

Astrophysicists settle century-old cosmic debate on magnetism of planets and stars
Three-dimensional FLASH simulation of the experimental platform, performed on the Mira supercomputer. Shown are renderings of the simulated magnetic fields before the flows collide. The universe is highly magnetic, with everything from stars to planets to galaxies producing their own magnetic fields.

Intense laser experiments provide first evidence that light can stop electrons
Intense laser experiments provide first evidence that light can stop electrons
By hitting electrons with an ultra-intense laser, researchers have revealed dynamics that go beyond 'classical' physics and hint at quantum effects. Whenever light hits an object, some of the light scatters back from the surface of the object. However, if the object is moving extremely fast, and if the light is incredibly intense, strange things can happen.

Intense laser experiments provide first evidence that light can stop electrons
ANN ARBOR-By hitting electrons with an ultra-intense laser, researchers have stopped them as effectively shooting them at a sheet of lead, demonstrating what's called "radiation reaction." This is the first time a team of researchers, which includes University of Michigan engineers and physicists, have demonstrated radiation reaction in the lab.

Rubber blanket at an atomic level
Rubber blanket at an atomic level
Stresses and strains can drastically alter the properties of a material, and TU Wien has now developed a method to make these internal deformations visible. Two-dimensional materials such as graphene, which consist of only one or a few atomic layers, have been a very promising aspect of materials science over recent years.

More evidence Earth-like planets could sustain life as their atmospheres probed
Three Earth-like planets orbiting the TRAPPIST-1 star have atmospheres that might be hospitable to life, a new study shows. Researchers using the NASA/ESA Hubble Space Telescope have analyzed the atmospheres of four Earth-sized extrasolar planets orbiting the nearby star TRAPPIST-1 , located about 40 light-years from Earth.
