20090071489 | In situ synthesis of composite nanoscale particles - A method of making composite nanoscale particles comprising subjecting a starting material to laser energy so as to form a vapor and condensing the vapor so as to form the composite nanoscale particles, wherein said composite nanoscale particles comprise a first metal and/or a first metal oxide incorporated in nanoscale particles of an oxide of a second metal, the first metal being different than the second metal. The starting material can comprise first and second metals or compounds of the first and second metals. The composite nanoscale particles can be formed in a reaction chamber wherein a temperature gradient is provided. The atmosphere in the chamber can be an inert atmosphere comprising argon or a reactive atmosphere comprising oxygen. The composite nanoscale particles are useful for low-temperature and near-ambient temperature catalysis. The composite nanoscale particles can be incorporated in the tobacco cut filler, cigarette paper and/or cigarette filter material of a cigarette to catalyze the oxidation of carbon monoxide to carbon dioxide. | 03-19-2009 |
20090275466 | PREPARATION OF INTERMETALLICS BY METALLO-ORGANIC DECOMPOSITION - A metallo-organic decomposition process for the preparation of intermetallic powders and films. A liquid mixture containing a first metal precursor and a second metal is heated to a temperature in a first temperature range so as to convert the first metal precursor to a first metal followed by heating to a temperature in a second temperature range so as to form an intermetallic compound by a solid state reaction between the first and second metals. The intermetallic compound can be used as a catalyst in cut filler and/or the filter of a cigarette. | 11-05-2009 |

20140150811 | GRAVURE-PRINTED, BANDED CIGARETTE PAPER - A cigarette and cigarette paper have a plurality of multilayer bands formed by printing a highly viscous aqueous film-forming composition. After heating the composition to lower its viscosity, the bands are applied to the cigarette paper by gravure printing the composition. The composition is quenched and gelatinized by contact with the cool cigarette paper reducing absorption of water by the paper and reducing wrinkling, cockling, and waviness. Multiple gravure printed layers may be used to form the bands. | 06-05-2014 |
