    Abstract: Flame spray pyrolysis can be performed using aqueous solvents for the delivery of metal and/or metalloid oxide precursors while obtaining desirably high flame temperatures for the synthesis of uniform submicron inorganic oxide particles. A multiple liquid channel nozzle can be used to deliver liquid for the formation of the aerosol that is combusted in the flame. One or both channels can deliver liquid with metal/metalloid precursors and/or organic fuels. Flame spray pyrolysis can be used to form metal tungsten oxide submicron particles. Metal tungsten oxide compositions can be used in the formation of transparent electrodes. If the transparent electrodes are formed from polymer inorganic particle composites, the composites can further comprise electrically conductive nanoparticles to improve the electrical conductivity.

    Abstract: The present invention relates to an electrical device comprising a substrate, a pair of electrodes arranged on the substrate and a functional layer arranged between the pair of electrodes, said functional layer comprising a functional domain being capable of transforming an external stimulus into an electrical signal or vice versa. The electrical device is characterized in that at least two conductive domains are dispersed in the functional layer. Said at least two conductive domains are separated from each other and are formed in each case by a particle or an agglomerate of particles of a conducting or semiconducting material having a higher electrical conductivity than the material of the functional domain. Each of the conductive domains form an electrically conductive path on the functional domain.
