The novel quaternary reduced molybdenum oxides MTi(0.7)Mo(0.3)Mo(5)O(10) (M = Sr, Eu) have been synthesized by solid-state reaction at 1400 degrees C for 48 h in sealed molybdenum crucibles. Their crystal structures were determined on single crystals by X-ray diffraction. Both compounds crystallize in the orthorhombic space group Pbca with 8 formula units(More)

In this paper we report the preparation of quasi-stoichiometric layers (Ba -deficient and Ba-rich) by MOCVD. The compositional effects on the morphology, structure and superconducting properties were studied too. 1.INTRODUCTION Many groups [I] have demonstrated that the morphology, microstructure and superconducting properties of YBa2Cu3e-6 (YBCO) thin(More)
This paper reports the results obtained by the development of a new wet method of hydroxyapatite (HA) thin layer deposition. The method is based on the localized precipitation of HA on metallic substrates activated by induction heating. The technique developed has been shown to allow for the complete coating of substrates with micrometric thin films of HA(More)
Elaboration of amorphous SiCPc: materials was performed using a conventional thermaly activated CVD at 100012003C from the '1MS-NH3-H2 system. 'I'he influence on the deposition rate and the composition was investigated using an experimental design by varq-ing: deposition temperature, pressure and hTb flow rate. A set of 16 samples SiCxNy with x!y ranged(More)
