Answer the questions : where are the atoms? (l ≈ Å) what do they do? (DE ≈ meV) Relations structure-properties Nonameter range accessible with special techniques (SAS) Platforms and tools : Large Scale Facilities - Medium/Small scale facilities Neutron and X-ray sources
Necessary to have access to sophisticated instruments small beam size : mm (X-rays) high brilliance => kinetics special techniques small angle scattering (nanometric scale) reflectometry (surfaces) inelastic scattering (vibrations) Complex sample environment high and low temperatures (mK to 3000K) high magnetic fields high pressures (Mbar) Why Infrastructures?

From theory to applications through LSF and integration Theory groups : From back of the envelope models to ab initio calculations (Universities and research centres) LSF : at the forefront of the analysis Extreme conditions Join the expertises through FAME Double feedback, cross fertilization
The nano-scaled local structure at the origin of ”giant” properties The case of relaxor ferroelectrics Nano-scaled local structure:Competing chemical, structural and/or physical properties remarkable properties: colossal magneto-resistance, giant piezoelectricity, high Tc superconductivity etc. Ex.: Relaxor ferroelectrics Local electric dipoles in a non polar matrix next generation piezoelectrics 1 à 50 nm Challenge Detailed knowledge of the structural and physical properties at the nano-scale Approach Combination of local probes and the external parameter high-pressure - important influence on volume and thus energetic system - understanding of strain etc. - building block for ab-initio calculations

MCM-41 Direct grafting X-ray absorption studies of functionalized mesoporous silica The X-ray absorption fine structure spectroscopy (EXAFS) was carried out at the ESRF on BM29 to characterize the local metal coordination environments in a series of recyclable oxidation catalysts based on a micelle-templated silica (MCM-41) derivatised with oxomolybdenum complexes. Mo Mo Mo Mo Mo–O 1.70 Å Mo–O 1.92 Å The XAFS studies showed that the nature of the surface species depends on the nature of X (Cl or Br) and also on the presence or otherwise of NEt3 in the grafting reaction (which serves to activate the surface silanols) Mo···Mo 3.27 Å Mo Mo Mo C.D.

Infrastructures • How to get beamtime (10 000 €/day)? • Normal procedure • Proposal => committee => decision => experiment • Takes 6 months, success rate 30%… 70% • Directors’ reserved beamtime • For urgent experiments, severely limited • Access programs of EU (TMR/LSF) • Beamlines operated by FAME scientists • LTP (long term proposal) • If the possibility is open “FAME” label (contacts with LSF Managements: LLB,..)

HOW TO GET MORE RESOURCES? First principle: • TO SHARE BETTER OUR OWN RESOURCES (PERSONNEL, FACILITIES…) THROUGH SPECIFIC AGREEMENTS Second principle: • TO MAKE FAME A QUALITY LABEL FOR EXCELLENCE AND SYNERGY IN RESEARCH, AND USE THIS LABEL: TO MAKE APPLICATIONS TO REGIONAL, NATIONAL AND INTERNATIONAL FUNDING AGENCIES • TO SUBMIT PROPOSALS TO THE EUROPEAN COMMISSION (EC) • TO MAKE APPLICATIONS THROUGH BILATERAL GOVERNMENTAL AGREEMENTS • TO NEGOTIATE CONTRACTS WITH INDUSTRIAL COMPANIES • TO HAVE PRIVILEGED ACCESS TO THE BEST RI
