If Nb3Sn is the best superconductor candidate for the realization of high field magnets (for 10-11 Tesla), its implementation remains delicate because of the great brittleness of material after the heat treatment necessary for the formation of Nb3Sn

Both X-ray diffraction and infrared spectroscopy on water confined between the lamellar bilayers of aerosol-OT (AOT) allowed us to explore the differences in connectivity between bulk and confined water when water layer thicknesses are allowed to var

New geometry of ceramic tubular membranes were designed to overcome the important problem of fouling encountered in micro- and ultrafiltration, by promoting turbulence and particle draining close to the membrane surface. Microfiltration tests showed

New geometries of zirconia and titania membranes were shown to enhance permeate flux during tangential filtration. The modified membrane surface acts as an integrated turbulence promoter while the system is free from vibration or any other problem in

The important problem of fouling encountered in micro- and ultrafiltration can be drastically reduced by promoting turbulence close to the surface of the membrane. To this purpose, we have developed a new ceramic tubular membrane geometry with a heli

Lithium intercalation into the lamellar vanadium oxide Li x V 2 O 5 is only reversible below x = 0.9. Insertion of larger amounts induces an irreversible phase transition that destroys the 2D character of the host. This structural change is due to at

The influence of multiple-scattering contributions in the X-ray absorption fine structure (XAFS) above the iridium LIII edge is discussed for the iridium oxide IrO2. It is shown that multiple scattering in the IrO6 cluster cannot explain the occurren

A vanadium oxysulfide is obtained by a reaction between water solutions of a vanadyl salt and sodium sulfide at room temperature. After drying under mild conditions, the formulation of this phase is V2O3S·3H2O. Thermogravimetric analyses show that i

A vibrational study of CrP 3 S 9.25 was undertaken in order to confirm the substitution of some S 2- anions by (S 2 ) 2- pairs as focused by a X-ray single-crystal analysis. Comparison between the infrared and Raman spectra allowed us to assign the m

Iridium oxide thin layers were studied by comparison with iridium dioxide. Analyses of commercial IrO2 showed the compound to be either an iridium oxychloride (Ir0.14IIIIr0.86IVO1.86Cl0.14) with an X-ray diffraction diagram in disagreement with the r
