Surface treatments of short term devices are actually evaluated to reduce the risk of infections, which in particular are one of the main causes of complications following catheter insertion. We have investigated the efficacy of ion beam techniques t

Polyimides are known to exhibit large ablation rates upon irradiation with excimer laser due to their high absorbance in the UV and low fluorescence yield. We have studied different regimes of laser ablation according to the fluence and studied the s

The initial stages of the three-dimensional metal organic vapor phase epitaxy growth of InP/GaP (100) and (111) A,B were studied by atomic force microscopy (AFM) and Rutherford back scattering (RBS). We have shown that the heteroepitaxial growth take

Different spectroscopic techniques show that poly(p-phenylene vinylene) films can be derived from a sulphonium precursor by irradiation with ion beams at energies of the order of 100 keV. The comparison with the pyrolysis conversion shows less chlori

Kapton-H thin films have been irradiated with heavy ions in the MeV/u range, in the electronic stopping power (Se) regime. Effective ion track radii are extrapolated from spin density measurements and are consistent with simulations of the radial dis

The implantation of alkali ions in LiF at liquid nitrogen temperature leads to the formation of a continuous metallic layer according to an insulator-metal transition. Due to the precipitation of the implanted ions, this metastable phase relaxes near
