One way to strengthen the mechanical properties of plastic materials is to add nanoparticles, forming that way a composite material.
Measurement of the cardiac electrical activity allows following the heart dynamics. Usually measured with electrodes during an electrocardiogram (ECG), this activity can also be studied by monitoring the magnetic component, induced by the circulation of the heart electric currents.

In collaboration with chemists of ENS Lyon and biophysicists of  DSV (IBiTeC-S), a team of LSDRM (IRAMIS/SIS2M) designed a cellular probe taking advantage of the extreme sensitivity of NMR (Nuclear Magnetic Resonance) of hyperpolarized xenon*.
  One of the key research topic in the field of ultra-short laser pulses (femtosecond: 10-15 s) is the stabilization of the position of the carrier envelope (called CEP for "Carrier Envelope Phase").
