Synthesis of V2O5 0.2 H2O xerogels by hydrolysis of alkoxide with addition of a surfactant molecule leads to a novel xerogel, which is more amorphous and has a slightly different structure from xerogels prepared by the same method without surfactant.

Addition of a surface active agent during hydrolysis of vanadium alkoxide allows to slow the gelification rate and to control the viscosity of the gel. Furthermore, after the surfactant elimination, the porosity of V2O5 greatly increases. Consequentl

Cadmium-containing hydroxyapatite and fluorapatite were prepared by a wet process in a basic medium and/or by a solid-gas reaction. Refinement of occupancy factor, using the Rietveld method, shows that the cadmium distribution is not strictly randomi

Neutron powder diffraction patterns were recorded using three samples of LixV2O5 with x = 0.4, 0.5 and 0.6. Extra peaks, not indexed by the e cell, infer two commensurate phases with cell parameters equal to 2b, a, 2c. In the e-LixV2O5 x a = 7.132(2)
