École Polytechnique hosted the 8th edition of Paris-Saclay Spring 2025, the annual entrepreneurship and research event on the Plateau de Saclay, one of the world's leading innovation and entrepreneurship hubs. Eight start-ups supported by X-UP, the École polytechnique's incubator, or stemming from its research ecosystem, are among the 50 young companies selected as the most promising on the Plateau de Saclay. One of them, Plasana Médical, is the winner of the Spring 50 competition.
Plasana Medical, founded in 2022 by Yves Matton, an entrepreneur in the Technofounders startup studio, and co-founded by Antoine Rousseau, Director of Research at the Plasma Physics Laboratory (LPP*) at École polytechnique, has won recognition for its innovative cold plasma technology. This innovation earned the company a place in Le Point's Palmarès des Inventeurs 2025, a prestigious award for entrepreneurs whose technological advances are transforming everyday life.
The École polytechnique and the Fondation de l' École polytechnique are renewing the “Space: sciences and challenges of the space sector” teaching chair, with the support of ArianeGroup and Safran. This program, led by Pascal Chabert, initially launched in 2019, contributes to teaching activities and student projects around space, and to the École polytechnique Student Space Center (CSEP).
Physicist and CNRS research director at the Laboratory of Condensed Matter for Physics, Claude Weisbuch has been honored by the French Academy of Sciences.
The BepiColombo probe flew over the planet Mercury and began measuring the characteristics of its magnetosphere, thanks in part to the MSA ion mass spectrometer to which the Plasma Physics Laboratory (LPP) contributed.
On its way to study Mercury, the BepiColombo probe flew over Venus. On board, the MSA instrument, for which the Plasma Physics Laboratory contributed to the design, detected carbon and oxygen ions escaping into space from the Venusian atmosphere. A first in this region.
Created by three alumni of École Polytechnique, the event dedicated to space and its exploration takes place from November 17th to 19th on the School’s campus. Hosting SpaceCon 2023 illustrates École Polytechnique's strong commitment to its research, training and innovation missions, and to meeting the most ambitious challenges in space research and exploration.
Confirming its contribution to research excellence in France and to the development of tomorrow's space technologies, École Polytechnique is participating alongside CNRS and Safran Electronics & Defense in the creation of a joint laboratory, COMHET, dedicated to improving space thruster technologies.
Three PhD candidates of École Polytechnique organized this year’s EuroTech winter school focused on “Accelerating Hydrogen: Towards Sustainable Production, Storage, and Conversion Technologies”. The seminar brought together over 30 PhD students from all six EuroTech partner universities across Europe from October 9-13, 2023, on campus and included a wide-ranging set of lectures and industry visits.
Edmond Baratte, a recent doctor from the Plasma Physics Laboratory, is leading a project combining plasma technologies to produce methane from carbon dioxide in the most carbon-neutral way possible. Thanks to funding from SATT Paris-Saclay, the aim is to design a prototype showing the process's efficiency
In many astrophysical processes such as solar flares, particle acceleration is likely to result from the reconnection of different magnetic field lines. In a paper published in Nature Communications, a team including researchers from the Intense Laser Laboratory and the Plasma Physics Laboratory shows that the geometry of these field lines plays a crucial role.
Pascal Chabert, CNRS research director at the Plasma Physics Laboratory and Professor at École Polytechnique, has just been awarded a CNRS silver medal. It recognises his significant work in the field of plasma physics, with applications for microelectronics and space propulsion.
