摘要:
A metal oxide catalyst carrier particle has a center portion and an outer skin portion each containing a first metal oxide and a second metal oxide. The center portion and the outer skin portion are different in composition. The mole fraction of the metal of the first metal oxide is higher in the center portion than in the outer skin portion and the mole fraction of the metal of the second metal oxide is higher in the outer skin portion than in the center portion. The second metal oxide is selected from the group consisting of rare earth oxides, except for ceria, and alkali earth metal oxides. In addition, platinum is supported on the metal oxide catalyst carrier particle, thus forming an exhaust gas purification catalyst.

Systems and methods for treating a fluid with a body are disclosed. Various aspects involve treating a fluid with a porous body. In select embodiments, a body comprises ash particles, and the ash particles used to form the body may be selected based on their providing one or more desired properties for a given treatment. Various bodies provide for the reaction and/or removal of a substance in a fluid, often using a porous body comprised of ash particles. Computer-operable methods for matching a source material to an application are disclosed. Certain aspects feature a porous body comprised of ash particles, the ash particles have a particle size distribution and interparticle connectivity that creates a plurality of pores having a pore size distribution and pore connectivity, and the pore size distribution and pore connectivity are such that a first fluid may substantially penetrate the pores.

A filter material of a filter element configured for application in a smoking article may include a fibrous substrate material finished with a fiber finish composition. The fiber finish composition may be formulated to selectively interact with at least one target component of mainstream smoke drawn through the filter element during use of the smoking article to selectively filter the target component from the smoke. The filter element may include multiple filter segments. Each filter segment may include a filter material having a finish composition formulated to selectively interact with a different target component. The various filter segments may be combined and/or arranged to selectively filter the mainstream smoke to achieve desired characteristics. Each filter segment may be formed from the same fibrous substrate material.

A metal-carbon composition including a metal and carbon, wherein the metal and the carbon form a single phase material, characterized in that the carbon does not phase separate from the metal when the single phase material is heated to a melting temperature, the metal being selected from the group consisting of gold, silver, tin, lead, and zinc.
摘要:
An encapsulated particle comprises a core particle and a polyurethane layer disposed about the core particle. The core particle can be various particles, such as fertilizer, biocides, flame retardants, seeds, etc. The polyurethane layer comprises the reaction product of an isocyanate component and an isocyanate-reactive component. The isocyanate-reactive component comprises a graft polyol having a continuous phase and polymeric particles. A method of forming the encapsulated particle comprises the steps of providing the core particle, applying the isocyanate and isocyanate-reactive components to the core particle, and reacting the isocyanate and isocyanate-reactive components to form the polyurethane layer. The encapsulated particle has excellent physical properties, such as increased water repellency, resiliency and shelf life.
