Preparative-scale synthesis of nonacene

After more than 70 years of attempts and controversies, nonacene, a molecule composed of 9 linearly fused benzene rings, has just been prepared at CEMES-CNRS by solid-phase thermal deprotection of two carbonyl precursors.

Time-resolved nanocathodoluminescence in a TEM

A collaboration between researchers from CEMES and LPS-Orsay allowed for the first time to perform a time-resolved cathodoluminescence experiment in a transmission electron microscope

An open-source software for simple data acquisition from complex experimental setups

Complex 3D magnetic configurations revealed by an original holography-tomography method

The 3D magnetic configuration of longitudinal and transverse multi-vortex states in CoNi magnetic nanowires has been highlighted using the holographic vector-field electron tomography method.

Crystallization Kinetics of Nitrogen Doped Ge2Sb2Te5

Where it is shown that N bonding with Ge increases the viscosity of GeSbTe glasses and slows down nucleation and growth mechanisms during crystallization, two characteristics which allow to fabricate PCM devices of increased thermal stability.
