From springs to lasers: energy’s mysterious cycle

fundamental physics

In 1953, scientists theorized the energy behavior of a chain of springs and revealed a paradox in fundamental physics. Over 60 years later, a group of researchers from IMT Lille Douai, CNRS and the universities of Lille and Ferrara (Italy) has succeeded in observing this paradox. Their results have greatly …


H2sys: hydrogen in the energy mix


I’MTech is dedicating a series of articles to success stories from research partnerships supported by the Télécom & Société Numérique Carnot institute (TSN), to which IMT and Femto Engineering belong. H2sys is helping make hydrogen an energy of the future. This spin-off company from the FCLAB and Femto-ST laboratories in …


Xenon instruments for long-term experiments
