Towards energy-saving data storage
Towards energy-saving data storage
A new material retains its special magnetic properties even at room temperature A new material could become the basis for future data storage devices, since it may enable significant reductions in energy demands in comparison to present-day hard drives. This is a material from the class of so-called magnetoelectric multiferroics, whose distinguishing characteristic is that their magnetic and electrical properties are coupled to each other.

Capturing an elusive spectrum of light
Capturing an elusive spectrum of light
Researchers led by EPFL have built ultra-high quality optical cavities for the elusive mid-infrared spectral region, paving the way for new chemical and biological sensors, as well as promising technologies. The mid-infrared spectral window, referred to as ‘molecular fingerprint region,' includes light wavelengths from 2.5 to 20 'm.

Hot on the heels of quasiparticles
Hot on the heels of quasiparticles
Electrons in a solid can team up to form so-called quasiparticles, which lead to new phenomena. Physicists at ETH in Zurich have now studied previously unidentified quasiparticles in a new class of atomically thin semiconductors.

Ceramics 3D printed from foams
Ceramics 3D printed from foams
ETH researchers have used an additive manufacturing process to print an extremely porous ceramic component. Manufacturing a material of this kind with a 3D printer is a considerable achievement. Doctoral student Carla Minas, from the Complex Materials group led by ETH Professor André Studart, has succeeded in creating a highly porous and yet extremely robust ceramic material, which she ‘printed' using an additive manufacturing process.

Bacteria can make underground nuclear waste repositories safer
Bacteria can make underground nuclear waste repositories safer
Naturally occurring bacteria could consume pent-up hydrogen gas in nuclear waste repositories to prevent radioactive leaks, say researchers at EPFL. Scientists may have found an unexpected ally in the long-term disposal of nuclear waste: bacteria. In a recent study, a research team led by EPFL discovered a microbial community made up of seven species of bacteria that live naturally hundreds of meters underground in the very rock layers that have been chosen to host Swiss nuclear waste.

Cellular test of strength
Cellular test of strength
Biological cells can expand, contract and interact with neighbouring cells. With an advancement in a microscopy technique, ETH Zurich researchers can now readily, directly, and accurately determine which forces are at work during cell motion and where. The technique is used in areas such as cancer research.

3D-nanoprinting to turbocharge microscopes
EPFL researchers have printed nanometric-scale sensors capable of improving the performance of atomic force microscopes. Tiny sensors made through nanoscale 3D printing may be the basis for the next generation of atomic force microscopes. These nanosensors can enhance the microscopes? sensitivity and detection speed by miniaturizing their detection component up to 100 times.

Affordable detectors for gamma radiation
Affordable detectors for gamma radiation
A research team at Empa and ETH Zurich has developed single crystals made of lead halide perovskites, which are able to gage radioactive radiation with high precision. Initial experiments have shown that these crystals, which can be manufactured from aqueous solutions or low-priced solvents, work just as well as conventional cadmium telluride semi-conductors, which are considerably more complicated to produce.

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.

New simulations of wind power generation
New simulations of wind power generation
ETH researcher Stefan Pfenninger and his colleague Iain Staffell from Imperial College London have developed new multi-decade simulations of wind power production in Europe. In doing so, they have uncovered significant distortions in the data used in the past, and have produced fresh simulations of wind power output with country-specific corrections.
