| アブストラクト: |
I will introduce the two EXAFS beam lines of the X-ray Absorption and Magnetic Scattering Group, BM29 and ID24.
A large portion of beam time on these two beam lines is dedicated to XAS studies in extreme conditions. I will show some recent results in this field. In particular, I will focus on a study on the pressure dependence of ion hydration in aqueous solutions performed on BM29 using a Paris Edinburgh Press and on a study of the evolution of the electronic structure and of the intramolecular distances in solid halogens as a function of pressure, performed on ID24 using a Diamond Anvil Cell.
Another important field of application of ID24 is dedicated to in-situ studies on heterogeneous catalysts. I will show an example of \"in-situ\" time resolved XAS study devoted to elucidate the correlation between the activity and selectivity of the catalyst and the structural modifications around the metal center. |
