Service Interdisciplinaire sur les Systèmes Moléculaires et les Matériaux
logo_tutelle logo_tutelle 

The “Service Interdisciplinaire sur les Systèmes Moléculaires et les Matériaux” is a fundamental research division which gathers about fifty permanent people (CEA, CNRS, university) and a score of students of all levels. Research studies can be divided in two major topics: nanochemistry and radiolysis. The main application domains are technologies of health, nanosciences and fundamental research for nuclear programs of the CEA.

 

Nanochemistry deals with supra molecular assemblies and ultra divided matter and uses specific characterisation techniques coupled with simulations of short and long distance interactions between molecules and/or ions. The main aims of the researches are the detailed understanding of molecule – metal coordination and interaction, the synthesis and/or the assembling of molecular species with specific properties and the physical chemistry of complex fluids, ultra divided matter and liquid interfaces.

Linear nanosecond electron pulse accelerator (10 MeV) used in radiolysis studies

Radiolysis is tackled by the study of physico-chemical and biochemical processes that occur during matter irradiation. Research mainly concerns the primary events of the radiolysis, the influence of confined media and solid - liquid interfaces on water radiolysis, the irradiation under extreme conditions of temperature and pressure and the biochemistry under irradiation.

Caractérisation de matériaux pour l'énergie / Characterization of materials for energy

Les différentes filières énergétiques, telles que l'énergie nucléaire ou encore les nouvelles technologies autour de l'hydrogène, vecteur énergétique, ou le photovoltaïque, demandent des matériaux adaptés, dont il faut tester la durabilité et la fiabilité.

Trois " métiers " de l'IRAMIS trouvent une extension naturelle vers la biologie :  L'ingénierie moléculaire, où les études d'interactions coopératives de molécules en solution trouvent une suite directe dans l'étude des protéines et des différents modes d'assemblage de molécules d'intérêt biologique, L'étude de la matière à haute densité d'énergie, où les travaux sur la radiolyse et les interactions rayonnement-molécule, se transposent directement à des molécules comme l'ADN, L'étude de la matière ultra divisée, domaine dans lequel les matériaux nanostructurés, la nanophysique et la biologie convergent naturellement.

Interfaces, fluides complexes et microfluidique

Selon le domaine (énergies bas carbone, nanosciences pour les technologies de l'information et de la santé (RF-TIS), interaction rayonnement-matière) plusieurs équipes de l'IRAMIS sont impliquées sur cette thématique.

Le développement des nanotechnologies s'appuie de plus en plus sur la logique d'assemblage spontané (auto-assemblage) ou non, des briques élémentaires que sont les nanoparticules.

Corrosion long terme de matériaux métalliques / Long term corrosion of multimaterials containing metals

Plusieurs pays envisagent de développer une technologie de barrières multiples pour la sécurité du stockage des déchets nucléaires. Une question centrale est de savoir modéliser le comportement sur le long terme (soit 100 à 1000 ans) des matériaux utilisés, en particulier des containers, en acier faiblement allié, et de la matrice vitrifiée.

X-rays are used to investigate the structural properties of solids, liquids or gels. Photons interact with electrons, and provide information about the fluctuations of electronic densities in heterogeneous matter. A typical experimental set-up is shown on Figure : a monochromatic beam of incident wave vector is selected and falls on the sample. The scattered intensity is collected as a function of the so-called scattering angle 2 teta.

Control command system for experiments with TANGO
Laboratory experiments are increasingly composed of electronic hardware and computer controlled. In most cases the quality of the equipment (mechanical, electronics) is very good but the software is inadequate and not very flexible to the needs of researchers. LIONS chose to use the open source control system  TANGO developed by a collaboration of European synchrotrons ans scientific institutes (ESRF, SOLEIL...).

Mass spectrometry is an instrumental technique of analysis resting on the separation, identification and quantification of the components of a sample according to their mass. Thus atoms, molecules or aggragates are extracted in the form of ions, then sorted by a dispersive system: sector of electric or magnetic field, quadripolar filter or time of flight.

Rayons X
Les rayons X, rayonnement électromagnétique au delà de l'ultra-violet lointain, couvrent une gamme de longueur d'onde autour du dixième de nanomètre. Cette distance est de l'ordre de la distance entre atomes dans la matière condensée. Ainsi les rayons X peuvent interagir avec ces atomes (diffraction) ou les électrons (diffusion).

Molybdenum Wide Angle X-Ray Scattering (WAXS)

x-rays, electromagnetic radiation beyond the remote ultraviolet ray, cover a range wavelength around the tenth of nanometer. This distance is about the distance between atoms in the condensed matter. The diffraction of x-rays thus makes it possible to probe the matter, and to obtain information on the structure, the order and the composition of materials.

The Raman microspectrometry is an analytical device of primary importance to characterize the crystalline structure of materials. It is a complementary technique to micro X-ray diffraction. This technique is well suited to characterize and determine the distribution of the phases formed in the corrosion layers of iron or steels during very long periods in various environments. Iron oxides, oxy-hydroxides and carbonates are the main phases encountered in these systems.

Anatomic scale : In collaboration with chemists from ENS Lyon and from CEA/iBiTeC-S and CBM Orléans, MRI experiments on living rodents are undertaken. 129Xe NMR-based biosensors designed to target a pulmonary disease are instilled in the lungs of the anesthetized animal. The acquisition is then performed just after the introduction of hyperpolarized xenon, which can occur many times and several tens of minutes after the biosensor instillation.
Laboratory 'Structure and Dynamics by Magnetic Resonance' :   Version française   The Laboratory 'Structure and Dynamics by Magnetic Resonance' (LSDRM) belongs to NIMBE, UMR CEA/CNRS 3685. The research axes are centered on the conception and the use of new NMR tools. Cutting edge methods and original approaches are proposed, from instrumental developments to molecular simulations.

Chemists of DSV (CEA-Life science Division) and physicists of DSM (CEA-Matter science Division) specialists of Nuclear Magnetic Resonance (NMR) have developed a new solid state NMR apporach to measure long inter-atomic distances. Based on the use of tritium, the hydrogen isotope with the highest sensitivity to NMR, this technique allows the determination of the conformation of small molecules bounded to their biological receptors.

One of the most important technological challenge of the century is the safe storage of nuclear wastes. In France, one part of the engineered barrier designed to separate the biosphere from wastes is a low alloy steel overpack. Thus, it is necessary to predict the very long term corrosion behaviour of this overpack for several centuries.
