Nanostructured amorphous carbon doped with nickel and tantalum : Characteriza...
Improvement of the properties of the thin films of amorphous carbon (called Diamond Like Carbon, DLC) and search for new functionalities for this type of thin films by... -
Magnetic properties of Co nanowires self-assembled by pulsed laser deposition
The subject of this thesis is the study of cobalt nanowires self-assembled in a CeO2 matrix. The spontaneous self-assembly of nanowires occurs in strongly Co-doped... -
New methods of metals determination in fly ash samples
Solid waste generated by our society are numerous, fly ashes are produced during the combustion of domestic or industrial waste in incinerators. Fly ashes are also... -
Experimental study and modeling of LIBS potentialities (Laser Induced Breakdo...
Laser ablation is widely spread for solid sample microanalysis. A tightly focused laser beam allows direct sampling of matter, the ablated mass can then be analysed... -
Experimental studies and modelling of laser induced plasmas in the framework ...
This work provides an original study about laser-matter interaction in the nanosecond regime, based on a coupling between the experiments and the modelling. The... -
Spectroscopic and fast imaging study of laser ablation plume from ceramic tar...
From the laser ablation of complex oxide ceramics (CCTO and BSTO), characterisation by time-space resolved spectroscopy and fast imaging are shown in this... -
Temporal and spatial characteristics of laser-induced plasma on organic mater...
This PhD work was devoted to the understanding of the laser-induced plasma on organic materials and theapplication of laser-induced breakdown spectroscopy (LIBS) to...
