The evolution of the passivating layer (during the first reduction/reoxidation cycle, in function of the number of reduction/reoxidation cycles and with the storage of the electrode in the electrolyte) formed at the surface of a lithiated carbon elec

Nous avons etudie les modifications de proprietes et de structures de monocristaux de quartz α, consecutives a une irradiation severe par des neutrons, des ions, des electrons ou des photons. Ce phenomene d'alteration du quartz sous irradiation port

Les interfaces metal-ceramique interviennent dans de nombreuses technologies, ou l'on recherche des proprietes electriques, optiques, magnetiques ou mecaniques particulieres. Ces proprietes dependent des caracteristiques des interfaces, comme leur st

The electronic structure of orthorhombic potassium niobate has been studied with a particular focus on empty electronic states. Occupied electronic states were analysed by X-ray photoelectron spectroscopy. Empty electronic states were probed by X-ray

the response of SiO2 quartz to ion-induced dense electronic excitations and the nature of the track-like damage are the main issues of the present work. The atomic structure of ion-irradiated quartz is probed by means of X-ray absorption spectroscopi

X-ray absorption spectra of α-quartz in the XANES region are presented both at oxygen and silicon K edges. The consequences of the electric dichroism of the samples on XANES structures are investigated. Polarization effects are detected when the ele

Present work deals with atomic and electronic alterations of the quartz structure by high energy ion irradiation. The atomic structure of irradiated quartz is probed by means of X-ray absorption spectroscopies (XANES, EXAFS). Electronic structure mod

We studied the structure of the (0110) α-quartz surface after different treatments (900°C vacuum or air heating and ion bombardment). The long-range order was investigated by low-energy electron diffraction (LEED), the mean-range order by X-ray abs

Thin PVDF foils were irradiated in the presence of oxygen with very energetic heavy ions (Xe, E = 44 MeV/amu) in the electrn stopping power energy range to produce peroxides along the ion paths. They were then grafter with styrene. Grafting yields we
