TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Compound: The metal oxide is titanium oxide, niobium oxide, hafnium oxide, tungsten oxide, indium oxide, tin oxide and/or zinc oxide. The metal oxide is nanosized material chosen from quantum dots, nanodots, nanotubes, nanowires, nanobelts and nanoparticles.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compounds: The dispersant(s) is dispersants of formulae (9 to 16). The solvent is aromatic hydrocarbon compounds, such as toluene and xylene, ether compounds, such as tetrahydrofuran and 1,2-butoxyethane, ketone compounds, such as acetone and methylethylketone, ester compounds, such as ethyl acetate, butyl acetate and butyl carbitol acetate (BCA), and alcohol compounds, such as isopropylalcohol, diethyleneglycol monobutylether, terpineol and 2-phenoxyethanol.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The metal oxide paste composition comprising metal oxide powder (in wt.%) (10-40), dispersant (1-10), and balance of the binder solution.Preferred Compound: The organic binder is chosen form acrylic resin, styrene resin, cellulose resin, methacrylic ester polymer, styrene-acrylic ester copolymer, polyvinylbutyral, polyvinyl alcohol, polyethylene oxide, polypropylene carbonate and polymethyl methacrylate. EXAMPLE - 16 g of commercially available nanocrystalline titanium dioxide (nc-TiO2) (RTM: Aeroxide P25); 80% anatase and 20% rutile was used. In order to remove water and volatile organics from the titanium dioxide powder before use, the titanium dioxide was dried in a vacuum at 130 degreesC. for 24 hours. As a solvent, 28.48 g of a 1.8:1 wt/wt mixture of alpha-terpineol and butyl carbitol acetate was used. As an organic binder, 2.4 g ethyl cellulose was used. Ethyl cellulose and the mixture of alpha-terpineol and butyl carbitol acetate were mixed with each other at a weight ratio of 3:5 in a silicone oil bath at 50 degreesC. so as to prepare an ethyl cellulose binder solution. To the prepared ethyl cellulose binder solution, the TiO2 nanoparticles were added, and the dispersant of Formula 9 as synthesized in the above synthesis example was then added. The mixture was milled with yttria-stabilized zirconia balls, thus preparing the metal oxide paste composition.
