  • Patent number: 8701681
    Abstract: Cigarette paper, methods for making cigarettes and methods for smoking cigarettes are provided, which involve the use of an oxyhydroxide compound that is capable of decomposing to form at least one product capable of acting as an oxidant for the conversion of carbon monoxide to carbon dioxide and/or as a catalyst for the conversion of carbon monoxide to carbon dioxide. The oxyhydroxide compound and/or the product formed from the decomposition of the oxyhydroxide can be in the form of nanoparticles. The oxyhydroxide compounds can be represented by MOOH where M is a metal selected from the group consisting of transition metals, rare earth metals, and mixtures thereof.

  • Publication number: 20120067737
    Abstract: A method and apparatus for producing particles from a starting material, which includes at least one electrochemically-reactive material, with metal counter ions is disclosed. The starting material can be a bulk material, a virgin material, a purified, recovered material, and/or an industrial waste. The electrochemical-reactive material can be recovered in particle form, including microparticles and/or nanoparticles. The recovered material can be substantially pure electrochemically-reactive material or an alloy of the electrochemically-reactive material. In some embodiments, one or more electrochemically-reactive materials can be selectively recovered from the starting material.

  • Patent number: 8023705
    Abstract: In a method for reconstructing an image from an echo planar imaging sequence, the echo planar imaging sequence is used to obtain multi-line k-space data from a subject and the multi-line k-space data are divided into odd line data and even line data. Fourier transform is performed on the odd line data and on the even line data separately to obtain corresponding amplitude images. The amplitude images obtained is this manner are added to produce the final image. The method effectively eliminates N/2 artifacts by over-sampling in the phase direction. By image reconstruction being carried out separately on the odd line data and even line data of k-space data and then integrating the images, the method effectively avoids the problem of the image signal loss caused by the mutual cancellation of the odd line data and even line data.
