A granular instability driven by gravity is studied experimentally and numerically. The instability arises as grainsfall in a closed Hele-Shaw cell where a layer of dense granular material is positioned above a layer of air. The initially flatfront defined by the grains subsequently develops into a pattern of falling granular fingers separated by rising bubbles of air. Atransient co...

Spin dependent hot electron transport and nanoscale imaging of metal/silicon structures In this work, we experimentally study spin-dependent hot electron transport through metallic multilayers (ML), containing single magnetic layers or “spin-valve” (SV) trilayers. For this purpose, we have set up a ballistic electron emission microscope (BEEM), a three terminal extension of scanning tunnelling ...

The aim of this thesis is the investigation of the spectroscopic properties and the electronic structure of vanadium in minerals with a geological and/or technological interest. V K-edge HERFD-XAS experiments were combined with a theoretical determination of the measured spectra. Two approaches were complementary used to calculate the spectra: an ab initio approach and a multielectronic one. Th...
