This thesis is logically divided into two main parts. The rst part present a ZEUS analysiswhich was performed on the data obtained from electron-proton collisions measured by theZEUS detector for the 2003-2007 running period. [...]

The microstructure and phase composition of Al/Ti/Al interfaces with respect to theirlocalization were investigated. An aluminum-flyer plate exhibited finer grains located close tothe upper interface than those present within the aluminum-base plate. [...]

The compressional behavior and the P-induced deformation mechanisms at theatomic scale of (Cs,K)Al4Be5B11O28(londonite, a ~7.31A and space groupP43m) were investigated by in situ single-crystal synchrotron X-ray diffractionwith a diamond anvil cell up to 26 GPa. No phase transition was observ ed withinthe P-range investigated: this material exhibits isotropi c compression (i.e., withcubic symmetry) in response to the applied pressure. [...]

We report a method for serial X-ray crystallography at X-ray free-electron lasers (XFELs), which allows for full use of the current 120-Hz repetition rate of the Linear Coherent Light Source (LCLS). Using a micropatterned silicon chip in combination with the high-speed Roadrunner goniometer for sample delivery, we were able to determine the crystal structures of the picornavirus bovine enterovirus 2 (BEV2) and the cytoplasmic polyhedrosis virus type 18 polyhedrin, with total data collection times of less than 14 and 10 min, respectively. [...]

A new complex ternary amide Rb2[Mn(NH2)4], whichsimultaneously contains both transition and alkali metal catalyticsites, is developed. This is in line with the recently reported TMLiHcomposite catalysts, which have been shown to effectivelybreak the scaling relations and achieve ammonia synthesisunder mild conditions. [...]
