The 17th meeting of technical coordination for the proposed superconducting tokamak JT-60SA was held in Grenoble in the INAC on 28 and 29 May 2013.
The use of strained silicon is a fundamental of modern nano-electronics, allowing to increase the mobility of charge carriers up to 150%. Researchers from INAC (in collaboration with LETI and ESRF) measured the deformation of individual silicon lines at the nanoscale.
We have modeled for the first time devices developed at LETI and STMicroelectronics with quantum methods. These simulations have provided important information on the physics of these devices.

The eighth edition of the Alpine Conference on Solid-State NMR took place in Chamonix in September 2013.  With over two hundred participants from twenty different countries, the conference is traditionally marked by the awarding of a prize in memory of R. Regitze Vol.
The cell wall of bacteria is composed of several biopolymers building a shell around the cell, which allows recognition and adhesion to hosts, as well as regulation of other important cellular functions.
Lithium ion batteries (LIB) are considered as prime candidates for electric vehicles. Among them, batteries with silicon nanoparticles (SiNPs) based negative electrode are very promising, thanks to their important energy storage capacity, ten times higher than the current ones.

Performances of the membrane-electrode assembly in polymer electrolyte fuel cells strongly depend on the features of the catalyst layer.
MRI is a non-invasive diagnostic tool providing high-resolution anatomical images consisting of 3D maps of the relaxation rates of the hydrogen nuclei in the body.

Sylvie Sauvaigo just received the prize in 2013 national contest for the creation of innovative companies. On Tuesday, July 2, 2013, Genevieve Fioraso chaired the ceremony national contest to support the creation of innovative companies.
The article entitled: "Amorphous Zinc Stannate (Zn2SnO4) Nanofibers Networks as photoelectrodes for Organic Dye-Sensitized Solar Cells", signed by the SPrAM, the SCIB and two Korean laboratories is published as front cover of the latest issue of Advanced Functional Materials. http://dx.

A dense forest of nanotrees is the secret for an "ideal" electrodes surface in silicon supercapacitors, as DSM researchers demonstrated using long and highly-doped silicon nanowires.

DNA lesions are recognized within our cells by a myriad of proteins playing key roles in important processes such as DNA repair or modulation of gene expression.

Electron pumps are devices delivering a quantized current when driven at a frequency f: I=Nef, where N is an integer and e the electron charge.
Contact : Vladimir Mineev
Vladimir P. Mineev (INAC, CEA-Grenoble) and Grigory E. Volovik (Aalto University School of Science) are the 2014 Lars Onsager Prize Recipients. This prize from the American Physical Society recognizes outstanding research in theoretical statistical physics including the quantum fluids.

The software Kwant is ​​available to the scientific community at http://kwant-project.org. This new platform aims beyond the traditional goal of making simulations fast, i.e. efficient in terms of computer time.
Researchers from SP2M demonstrate a novel optical antenna which funnels very efficiently the emission of a semiconductor quantum dot into a Gaussian optical beam.

Measurements of elementary excitations of superfluid helium performed at INAC show the importance of process in three excitations processes in Bose condensates.   Liquid helium study is an extremely rich subject that can address many issues of quantum and statistical physics.
Magnetic nanoparticles are more and more used for various biotechnological applications, due to their capability to exert actuation on biological species thanks to magnetic fields applied remotely.

Spintronics applications use ferromagnetic(F)/antiferromagnetic(AF) exchange bias (EB) interactions to set the reference direction required for the spin of conduction electrons. They therefore may involve layers intermixing originating from F/AF interfaces.
Contact : Léa Cuchet
Usually, magnetic tunnel junctions consist of electrodes made of an alloy of cobalt, iron and boron (CoFeB) and a tunnel barrier in magnesium oxide (MgO). To bring perpendicular anisotropy to such structures, multilayers of cobalt and platinum (Co/Pt) may be used.
In May, at the "International Memory Workshop" organized by the IEEE in California, Spintec and Crocus Technology presented the first demonstration of magnetic memory cells capable of performing a logic function.
