  • Publication number: 20090071489
    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.

  • Publication number: 20070289676
    Abstract: A high strength and creep resistant soft magnetic Fe—Co alloy includes, in weight %, Fe and Co such that the difference between the Fe and Co is at least 2%, at least 35% Co, and 2.5%?(V+Mo+Nb), wherein 0.4%?Mo and/or 0.4%?Nb. This alloy can further include B, C, W, Ni, Ti, Cr, Mn and/or Al. A vanadium-free high strength soft magnetic Fe—Co alloy includes in weight %, Fe and Co such that the difference between the Fe and Co is at least 2%, and at least 15% Co, the alloy further satisfying (0.1%?Nb and 0.1%?W) or 0.25%?Mn. This alloy can further include B, C, Ni, Ti, Cr and/or Al.

  • Publication number: 20070006889
    Abstract: A virtual or augmented reality smoking system is provided herein. A smoker using the system can experience a virtual reality of smoking by puffing on a cigarette shaped article and experiencing the taste or aroma from the article while simultaneously viewing a generated image of a burning cigarette and exhaled and sidestream smoke. Additionally, the room environment may be simulated to give the experience of smoking in a setting of the smoker's choice (virtual reality) or the image of a burning cigarette and smoke may be superimposed on a live or natural image of the smoker's environment (augmented reality).

  • Publication number: 20050279372
    Abstract: A component of a cigarette comprises a silver-based catalyst for the conversion of carbon monoxide to carbon dioxide. The silver-based catalyst comprises particles (e.g., nanoscale or larger sized particles) of metallic silver and/or silver oxide supported in and/or on metal oxide support particles. The silver-based catalyst can be incorporated into a cigarette component such as tobacco cut filler, cigarette paper and cigarette filter material to reduce the concentration of carbon monoxide in the mainstream smoke of a cigarette during smoking. The catalyst can also be used in non-cigarette applications.
