En route to better transformers
Researchers at the Paul Scherrer Institute PSI have found a way of looking inside the iron core of transformers. Transformers are indispensable in regulating electricity both in industry and in domestic households. The better their iron cores are magnetized, the less energy they lose and the more efficiently they work.

Stretchable electronics that quadruple in length
29. EPFL researchers have developed conductive tracks that can be bent and stretched up to four times their original length. They could be used in artificial skin, connected clothing and on-body sensors. Conductive tracks are usually hard printed on a board. But those recently developed at EPFL are altogether different: they are almost as flexible as rubber and can be stretched up to four times their original length and in all directions.

Upside-down lightning strikes
11. Upward lightning strikes initiate on the ground and head skyward. These discharges, which usually begin at the top of tall and slender structures, pose a real risk for wind turbines.

Going back in time to locate short circuits in power grids
10. EPFL researchers have come up with a method to determine the exact location of short circuits in a power grid. This is an important step towards operating complex power grid topologies that enable the massive integration of renewable energy resources. When a high-voltage power line is damaged by wind, ice or a tree, electricity utilities must quickly find the fault location and repair it to meet the power quality requirements or avoid cascade blackout.

Tiny magnets mimic steam, water and ice
Researchers at the Paul Scherrer Institute (PSI) created a synthetic material out of 1 billion tiny magnets. Astonishingly, it now appears that the magnetic properties of this so-called metamaterial change with the temperature, so that it can take on different states; just like water has a gaseous, liquid and a solid state.

Electronic circuits with reconfigurable pathways closer to reality
Multitasking circuits capable of reconfiguring themselves in real time and switching functions as the need arises - this is the promising application stemming from a discovery made at EPFL and published. Other potential uses: miniaturising our electronic devices and developing resilient circuits. Will it be possible one day to reconfigure electronic microchips however we want, even when they are in use? A recent discovery by a team at EPFL suggests as much.

Observed live with x-ray laser: electricity controls magnetism
Data on a hard drive is stored by flipping small magnetic domains. Researchers have now changed the magnetic arrangement in a material much faster than is possible with today's hard drives. The researchers used a new technique where an electric field triggers these changes, in contrast to the magnetic fields commonly used in consumer devices.

An innovative method for measuring nanoparticles
Precise measurement of the molecular weight, size and density of a nanoparticle in a single procedure is now possible, thanks to an ultracentrifugation method. Although nanoparticles are used in a variety of domains - such as medicine, solar energy and photonics - there is still much about them to be discovered.

Energy from the stars
The international ITER project is setting out to store the energy of stars in a reactor. To meet this challenge, scientists must be able to measure the properties of matter in fusion. Researchers have just successfully tested some sensors that are necessary for the ITER prototype. The scientists' ambition is to keep matter with a temperature of several million degrees contained here on Earth.
