CEMES inaugurates new facilities unique in the world: the electron microscope I2TEM and the picoLab building financed amounting to € 18M (CPER 2007-2013). Atoms have been "seen" in the CEMES and molecules and functional nanomaterials have been constructed. The ambition is now to "communicate with the nanoworld".
Magnetic domain wall structure in a nano-cylinder
Scientists of the CEMES, in collaboration with scientists of the LSI Ecole Polytechnique, have succeeded in studying the variation of the 3D structure of a magnetic domain wall in nickel nano-cylinders of diameter between 50 and 90 nm.
Des états plasmoniques 2D codent l'information
By controling the 2D growth of Au colloids and by studying teir non-linear optical properties, E. Dujardin, A. Arbouet, C. Girard et al. Demonstrate that plasmonic modes can be directly probed by optical microscopy. These results, published in Nature Materials, open the way to a new optical information paradigm based on the engineering of plasmonic modes. DOI: 10.1038/NMAT3581
Legros-Prix Bessel
26 February 2013
In recognition of the research he has conducted for the last 18 years, mainly at CEMES in Toulouse, Dr. Marc Legros has been awarded the Friedrich Wilhelm Bessel research prize from Germany’s Humboldt Foundation. This prize supports international scholars in all fields to carry out research in Germany, and for German scholars to go abroad.

Nouveau DualBeam au CEMES
10 October 2012
The new Dual Beam microscope – Focused Ion Beam (FIB) and Scanning Electron Microscope (SEM)–, bought in the frame of the MIMETIS project (EQUIPEX funding) is now fully operational at CEMES. This ensemble, equipped with numerous tools (gas injectors, electron and ion detectors, micromanipulator), allows the observation but also the milling of materials at the nanometer scale and subsequently the c...

14 September 2012
Researchers of the IBM-Zurich Research laboratory, of the CIQUS-Santiago de Compostela and of the NanoSciences Group –CEMES-CNRS Toulouse, have shown it is possible to map the carbon-carbon bond orders within a single molecule of polyaromatic hydrocarbon or within a single molecule of fullerene with a Non-Contact Atomic Force Microscope in which the tip has been functionalized by a CO molecule.

The color of silicon-germanium nanowires
22 August 2012
Researchers of Toulouse (CEMES), Grenoble (LTM) and Sfax have studied the scattering of light by isolated silicon-germanium nanowires. They showed that the nanowire color can be modified as function of the nanowire diameter, composition and dielectric environment.
16 July 2012
The new Transmission Electron Microscope (TEM) I2TEM financed by the CPER «MET ultime» and the EQUIPEX project «MIMETIS», is now working in CEMES. I2TEM is the result of cooperation between CEMES-CNRS and Hitachi High technology to design and build a unique Cold FEG TEM dedicated to electron interferometry, Lorentz imaging and in-situ experiments.

Highlight Calmels
02 July 2012
Researchers from CEMES-Toulouse, IJL-Nancy and synchrotron SOLEIL have identified the most important electron states contributing to the tunnel current in Fe1-xCox/MgO/Fe1-xCox magnetic tunnel junctions. They explained the decrease of the magnetoresistance observed for Co-rich electrodes in terms of an interface electron state which starts becoming occupied for Co content above 25%.
“All-solid-state” monolithic lithium-ion batteries
Stone Age Revisited
18 June 2012
The preparation by Spark Plasma Sintering of “all-solid-state” monolithic lithium-ion batteries in few minutes allows to obtain cells with good electrochemical performances, especially at high temperature (› 80°C). The “all-solid-state” technology now offers a viable answer to the safety problems of existing batteries.
