Integrated photonic circuits could help close the 'terahertz gap'

EPFL ETH Zurich

EPFL researchers have collaborated with those at Harvard and ETH Zurich on a new thin-film circuit that, when connected to a laser beam, produces finely tailorable terahertz-frequency waves. The device opens up a world of potential applications in optics and telecommunications.

Watching the metabolism at work

Researchers from ETH Zurich and the University of Zurich are taking magnetic resonance imaging a step further. With their new method, they can visualise metabolic processes in the body. Their objective is to improve the future diagnosis and treatment of heart disease.

Tackling the high-voltage needs of next-gen satellites

Scientists at the Swiss Plasma Center at EPFL, in collaboration with Beyond Gravity and with the support of the ESA, have developed a slip ring assembly that can more than triple the operational voltage of new-generation, high-voltage satellites.

"Grätzel" solar cells achieve a new record

Scientists at EPFL have increased the power conversion efficiency of dye-sensitized solar cells ("Grätzel cells") beyond 15% in direct sunlight and 30% in ambient light conditions.

The e-Sling electric aircraft takes off

The four-seater electric aircraft “e-Sling”, which was developed by ETH students, has taken flight for the first time. The student project has taken two years and a lot of dedication.

Researchers discover a material that can learn like the brain

EPFL researchers have discovered that Vanadium Dioxide (VO₂), a compound used in electronics, is capable of “remembering” the entire history of previous external stimuli. This is the first material to be identified as possessing this property, although there could be others.
