20110133857	INTERFACE ACOUSTIC WAVE DEVICE - The present invention relates to the field of acoustic wave devices, and particularly to that of transducers capable of operating at very high frequencies, from a few hundred MHz to several gigahertz, and its subject is more particularly an interface acoustic wave device including at least two substrates and a layer of ferroelectric material, the latter being contained between a first electrode and a second electrode and having first positive-polarization domains and second negative-polarization domains, the first and second domains being alternated, wherein the assembly constituted by the first electrode, the layer of ferroelectric material, and the second electrode is contained between a first substrate and a second substrate.	06-09-2011
20100033902	COMPOSITE CONTAINING CARBONIZED BIOPOLYMERS AND CARBON NANOTUBES AND METHOD OF MAKING THE COMPOSITE - A composite suitable as a charge-storing material for electrochemical capacitors contains carbon nanotubes and a carbonaceous materiel. The carbonaceous material is the carbonization residue of a biopolymer or seaweed rich in heteroatoms. Wherein the carbonization residue of the biopolymer or seaweed is electrically conductive and has a heteroatom content as detected by XPS of at least 6%.	02-11-2010
