A rare observation of a blue aurora at mid-latitude

Red or even green aurorae observations at mid-latitudes are rare but not exceptional. However, while high-latitude sightings of blue aurorae are frequent, sighting at mid-latitudes have rarely been reported. During …

No need to hit the iron while it’s… small!

Scientists from CNRS have studied the shape evolution of gold nano-tetrapods and revealed a two-step kinetics process: the four arms—initially sharp—quickly blunt, followed by a slow retraction towards an almost …

Colloidal phase behavior of high aspect ratio clay nanotubes in symmetric and asymmetric electrolytes

Imogolite nanotubes (INTs) are unique anisometric particles with monodisperse nanometric diameters while the aspect ratio can be controlled by the synthesis conditions. It thus appears as an interesting model system …

About us

The team Matter and radiation (MATRIX), led by Erwan PAINEAU, studies the relationships between structure and properties for a wide range of material classes. It mainly uses X-ray scattering techniques and has developed an original and specific instrumentation for this purpose. It also benefits from a privileged relation with synchrotron and neutron facilities. Research topics: magnetic quantum compounds, polymers, elastomers, liquid crystals, nano-objects, nanomaterials.
