Nanoscale Particles Of Iron Aluminide And Iron Aluminum Carbide By The Reduction Of Iron Salts

View page
US Patent:
7004993, Feb 28, 2006
Filed:
Jun 13, 2003
Appl. No.:
10/460318
Inventors:
Yezdi B. Pithawalla - Richmond VA, US
Sarojini Deevi - Midlothian VA, US
Assignee:
Philip Morris USA Inc. - Richmond VA
International Classification:
B22F 9/24
C01B 31/30
US Classification:
75351, 75365, 423115, 423439
Abstract:
A method of making intermetallic nanoscale particles comprising iron aluminide and/or iron aluminum carbide comprising the steps of preparing a mixture of a solvent, an iron salt and LiAlH, and heating the mixture to form the intermetallic nanoscale particles. The intermetallic nanoscale particles, which can comprise intermetallic nanoscale particles of iron aluminide and/or iron aluminum carbide in an alumina matrix, are capable of reducing the amount of 1,3-butadiene in the mainstream smoke of a cigarette.

Copper And/Or Zinc Alloy Nanopowders Made By Laser Vaporization And Condensation

View page
US Patent:
7413725, Aug 19, 2008
Filed:
Aug 11, 2004
Appl. No.:
10/915693
Inventors:
M. Samy El-Shall - Richmond VA, US
Sarojini Deevi - Midlothian VA, US
Yezdi B. Pithawalla - Richmond VA, US
Seetharama C. Deevi - Midlothian VA, US
Assignee:
Philip Morris USA Inc. - Richmond VA
International Classification:
C01G 9/02
C01G 11/02
C01G 13/02
B01J 23/00
B01J 23/70
US Classification:
42359414, 502343, 502345
Abstract:
A method of making Cu, Zn, and/or Cu/Zn alloy nanoparticles subjects one or more targets to laser energy to form a vapor and condenses the vapor to form nanoparticles having an average particle size of less than 20 nm. The optional application of an electric field results in nanoparticles with aspect ratios greater than 1. The target(s) can be a single target or separate targets comprising a mixture of copper, zinc, and/or copper/zinc. When separate targets are used, the laser beam can be split to form two separate beams each of which is made incident upon one of the targets. The nanoparticles can be formed in a chamber having an inert atmosphere or a reactive atmosphere and a convection current is created in the chamber by maintaining the top plate at a lower temperature than the bottom plate.

Continuous Process For Surface Modification Of Cigarette Filter Materials

View page
US Patent:
7478637, Jan 20, 2009
Filed:
Nov 9, 2004
Appl. No.:
10/984637
Inventors:
Georgios D. Karles - Richmond VA, US
Yezdi B. Pithawalla - Richmond VA, US
Assignee:
Philip Morris USA Inc. - Richmond VA
International Classification:
A24C 1/20
US Classification:
131207, 131364
Abstract:
Process and apparatus are provided for depositing target materials onto the surface of a moving substrate which may be used in the preparation of composites, cigarette filters, cigarette wrapper, bandages, biomedical applications, cosmetic and cleaning materials, and the like. A moving substrate comprising a fibrous mat or paper passes through one or more reaction chambers each having hot and cold regions. At least one target material is positioned in the hot region, and a laser beam ablates the material thereby producing modified additive material. As the substrate moves through the cold region of the reaction chamber, the modified additive material adheres to the exposed surface of the substrate.

Filed:
Oct 25, 2004
Appl. No.:
10/972204
Inventors:
Sarojini Deevi - Midlothian VA, US
Rangaraj S. Sundar - Midlothian VA, US
Yezdi B. Pithawalla - Richmond VA, US
Assignee:
Philip Morris USA Inc. - Richmond VA
International Classification:
A24B 15/18
US Classification:
131334, 502300, 502344, 502345
Abstract:
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.

US Classification:
131365, 131360, 131349, 131347, 131284, 162139
Abstract:
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.
