Thin films of tungsten oxide were deposited on SnO2:F coated glass using pulsed laser deposition. The structure, morphology, composition of the films and thus the electrochromic properties are strongly dependent on the conditions of deposition. Empha

We have successfully grown in situ, by laser ablation, the following heterostructures: Pb(Zr0.52Ti0.48)O3 / YBa2Cu3O7 / CeO2 / (1102) Al2O3(PZT/YBCO/CeO2/Al2O3), Pb(Zr0.52Ti0.48)O3 / YBa2Cu3O7 / (100) SrTiO3(PZT/YBCO/STO), and Pb(Zr0.52Ti0.48)O3 / Sr

We present a transmission electron microscopy study of the discommensuration (DC) walls in the superconducting bismuth-cuprates. High resolution evidence for the translation slip across a wall is obtained for the first time in these materials. A cons

Silver-palladium alloys in the whole composition range have been produced by mechanical alloying using, as metallic precursor, silver and palladium powders prepared in our laboratory by the polyol process. The influence of milling conditions and isot

The nature of hydrogen bonding and its influence on the electronic properties and the atomic structure was investigated in two types of a-C:H films prepared in a d.c. multipolar plasma system from pure methane at different substrate bias, by performi

Homologues of the orthorhombic form of Mo4O11, belonging to the series Mm+2O3m+4, have been prepared in the Mo-W-O system and structurally characterized by X-ray powder diffraction and electron microscopy. The structures are built up of corner-sharin

In specimens prepared by gentle reduction of the mixed oxide Mo0.72W0.28O3 (ReO3-type structure) phases isotypic of the monoclinic form of Mo4O11 have been observed and characterized by electron diffraction and high resolution electron microscopy tec

The electrochemical impregnation of porous nickel sintered plates has been investigated to gain a better understanding of the structure, tenure, and composition of the deposited active material. It was found that the nature of this material depends o

New oxides have been prepared in the WO3-MoO3 system, the structure of which can be described by corner-sharing (MO6) octahedra forming structures of hexagonal tungsten bronze-type, ReO3-type and pyrochlore-type. These oxides are metastable phases wh
