techniques at storage rings and FELs. Time-resolved XAFS experiments have taken up momentum at SRs and FELs and now offer time-resolution in the 100 fs time frame, which is of high relevance for many chemical systems.

(XES) provide information on electronic structure that is complementary to X-ray diffraction. They can identify ligands, determine the chemical state of the metal site and some ligands and are very sensitive to X-ray damage. XES unlike XAS does not require a monochromatic X-ray beam and is thus compatible with a diffraction setup. This property is particularly interesting for crystallography at X-ray free electron lasers. The MS will review the state of the art, introduce the technique, present recent experiments (also at LCLS) and discuss future applications.

with implementation of photons for materials characterisation which can be used for innovation in industry. Therefore, research with photons has contributed to the development of a wide variety of products such as plastics, cosmetics, chemicals, building materials, life science and even packaging materials.
The synchrotron based X-ray absorption, diffraction, tomography and scattering due to very high source intensity, wide range of covered energy, polarity of radiation are helping in the solving a current research and development issues. The MS will present the examples of such studies performed for variety of industrial technological problems.

of XAS analysis (combined with molecular dynamics, for example) in the study of the solvation structure of metals. This includes inorganic and organometallic metal ions, solvation effects on metalloproteins and high pressure interactions.

of EXAFS analysis at the nanoscale. To date, different papers have mainly addressed the existence of surface effects in terms of the reduction of the number of coordination. This is a controversial issue that needs clarification coupled with the analysis of disorder effects. Finally, what EXAFS (XANES) can really say regarding the existence of vacancies should be also an interesting topic.

naturally complementary with crystallographic methods. Multiple Wavelength Anomalous Dispersion is intrinsically a combined XRD/XAS technique, for example. XAFS and XANES combine to give detailed information on dynamical bonding, dynamical versus static disorder, oxidation and coordination number of active or intermediate states which complement other techniques extremely well. Further, XAFS and XANES combine well with IR to probe detailed molecular dynamics.
