193. Unraveling how electronic and spin structures control macroscopic properties of manganite ultra-thin films
Dr Andrivo Rusydi (National University of Singapore)
Perovskite manganites exhibit fascinating transport and magnetic properties. With the development of thin film technologies, more exotic properties have been observed in doped-manganites over a wide range of temperatures. Unraveling the interplay of spin, charge and orbital degrees of freedom that drives exotic, macroscopic properties is therefore crucial for the understanding of strongly...

XAFS can now be used to investigate electron inelastic mean free paths, dynamical and thermal bonding, to measure nanoroughness and most importantly to assess the significance of alternate hypotheses with derived experimental uncertainty. These key developments will be discussed. A new approach is introduced for determining XAS spectra on absolute and relative scales using multiple solutions...

Metal hydrides have long been explored for their potential application in a variety of technological applications including hydrogen storage materials for energy applications, fast-ion conductors and sensors. For thermal energy storage, such as concentrating solar thermal energy storage, metal hydrides are required to operate at temperatures in excess of 500 °C . This temperature is too...
142. EXAFS insights into the crystal-chemistry of nickel in tropical ultramafic areas: A survey at the molecular environmental level in New Caledonia.
Dr Farid JUILLOT (Institut de Mineralogie, de Physique des Materiaux et de Cosmochimie IMPMC, UMR CNRS 7590, UR IRD 206, Universite Pierre et Marie Curie UPMC, 75005 Paris, France)
In this presentation, we will show how Ni K-edge EXAFS data from the Australian Synchrotron (Melbourne) and several facilities worldwide (ESRF-France, ELETTRA-Italy, SOLEIL-France, SSRL-USA) helped us to depict the crystal-chemistry of nickel in New Caledonia, the third nickel producer in the world thanks to its geological setting (one-third of the surface covered with lateritic regoliths...
