A solid oxide fuel cell structure obtainable by selective electrochemical processing, comprising an electrolyte membrane (4) formed by a thin film more than 50nm but less than l0[mu]m thick, covering a supporting structure (1) made of a bulk substrate, the ...
Micro-system for active vibratory insulation, characterised in that it comprises a stand which includes a frame (1) and at least two beams (2a, 2b) which interlock and carry or are intended to carry an element requiring stabilisation (3), said beams (2a, 2 ...
Pb(Zr-x,Ti1-x)O-3 thin films of homogeneous composition were synthesized by means of a modified sol-gel route on Pt(111)/TiOx/SiO2/Si substrates. The usually observed gradient in B-site composition could be reduced from +/- 12 to +/- 12.5 at% amplitude in ...
BaxSr1-xTiO3 (BST) and its composite films have been studied for the improvement of the tunable performances via nano-structual control. The strong correlation between strain and tunability similar to that between strain and permittivity was confirmed in t ...
