The École polytechnique fédérale de Lausanne (EPFL) is a research institute and university in Lausanne, Switzerland, that specializes in natural sciences and engineering. It is one of the two Swiss Federal Institutes of Technology, and it has three main missions: education, research and technology transfer at the highest international level. EPFL is widely regarded as a world leading university. The QS World University Rankings ranks EPFL 12th in the world across all fields in their 2017/2018 ranking, whilst Times Higher Education World University Rankings ranks EPFL as the world's 11th best school for Engineering and Technology. EPFL is located in the French-speaking part of Switzerland; the sister institution in the German-speaking part of Switzerland is the Swiss Federal Institute of Technology in Zurich (ETH Zurich). Associated with several specialised research institutes, the two universities form the Swiss Federal Institutes of Technology Domain (ETH Domain), which is directly dependent on the Federal Department of Economic Affairs, Education and Research. In connection with research and teaching activities, EPFL operates a nuclear reactor CROCUS, a Tokamak Fusion reactor, a Blue Gene/Q Supercomputer and P3 bio-hazard facilities.

Integrated photonic circuits could help close the ‘terahertz gap’

“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 …

Using machine learning to forecast amine emissions

“Scientists at EPFL and Heriot-Watt University have developed a machine learning approach to accurately predict potentially harmful amine emissions from carbon-capturing plants. Global warming is partly due to the vast amount of carbon dioxide that we release, mostly from power …

Improving the operational stability of perovskite solar cells

“Scientists at EPFL have found a way to improve the operational stability of perovskite solar cells, a crucial step towards their commercialization. Hybrid perovskites are materials made from metal halide frameworks interspersed with organic cations. They have attracted a lot …

Locomotion modeling evolves with brain-inspired neural networks

“A team of scientists at EPFL have built a new neural network system that can help understand how animals adapt their movement to changes in their own body and to create more powerful artificial intelligence systems. Deep learning has been …

Photonics chip allows light amplification

“Scientists at EPFL have developed photonic integrated circuits that demonstrated a new principle of light amplification on a silicon chip. It can be employed for optical signals like those used in Lidar, trans-oceanic fiber amplifiers or in data center telecommunications …

Unraveling the secrets of microplastics released by tires

“In Switzerland, tire and road wear particles are one of the biggest sources of microplastics released into the environment, yet the chemical compounds contained in those particles – and their effects – remain largely a mystery. To remedy that knowledge gap, scientists …

“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. Mesoscopic dye-sensitized solar cells (DSCs) were invented in 1990s by Brian O’Regan and …

New PET-like plastic made directly from waste biomass

“EPFL scientists have developed a new, PET-like plastic that is easily made from the non-edible parts of plants. The plastic is tough, heat-resistant, and a good barrier to gases like oxygen, making it a promising candidate for food packaging …

EPFL scientists take modeling to new heights

“EPFL’s Platform of Hydraulic Constructions has been commissioned to model a future hydropower plant in Australia. As part of its work, the team has built an outsize replica on campus. In the modeling world, 1:25 is an extremely …

Objects can now be 3D-printed in opaque resin

“A team of EPFL engineers has developed a 3D-printing method that uses light to make objects out of opaque resin in a matter of seconds. Their breakthrough could have promising applications in the biomedical industry, such as to make artificial …
