  • Patent number: 9112192
    Abstract: The present invention provides geometric arrangements for channels through which liquids or other fluids can be made to flow, for enhanced performance of fuel cells or other chemical or biochemical reactors or analyzers. Systems and methods including these improved geometries are described herein for enhanced performance of a variety of devices. Specifically, in one set of embodiments, the reactors comprise one or more microchannels comprising a tapered cross-sectional area and at least one reactive surface portion. By flowing a liquid comprising one or more reactants through the channel such that the cross-sectional area decreases in a downstream direction, relatively more reactant may be supplied to the wall at downstream positions relative to the amount that would be supplied in a system without a tapered cross-section. In some embodiments, the microchannel may be constructed and arranged such that the amount of reactant supplied to the wall conforms to a predetermined distribution.

  • Publication number: 20150216935
    Abstract: Compositions and methods for producing autologous brown adipose cells in vitro or in vivo are provided. In particular, a drug delivery device is described that recruits adipose stem cells (ASCs) to a site in the body of a subject. These ASCs may then be isolated and induced to differentiate into autologous brown adipose cells. Alternatively, the drug delivery device may also include differentiation factors that induce differentiation of the recruited ASCs into brown adipose cells in vivo. The brown adipose cells produced by these methods may be used therapeutically to treat conditions, such as obesity and diabetes.

  • Patent number: 9098725
    Abstract: In one exemplary embodiment, an apparatus includes a memory storing data and a processor performing operations. The apparatus generates or maintains an accumulation tree for the stored data—an ordered tree structure with a root node, leaf nodes and internal nodes. Each leaf node corresponds to a portion of the data. A depth of the tree remains constant. A bound on a degree of each internal node is a function of a number of leaf nodes of a subtree rooted at the internal node. Each node of the tree has an accumulation value. Accumulation values of the root and internal nodes are determined by hierarchically employing an accumulator over the accumulation values of the nodes lying one level below the node in question. The accumulation value of the root node is a digest for the tree.

  • Patent number: 9093715
    Abstract: A new structure-control strategy to optimize nanoparticle catalysis is provided. The presence of Au in FePtAu facilitates FePt structure transformation from chemically disordered face centered cubic (fcc) structure to chemically ordered face centered tetragonal (fct) structure, and further promotes formic acid oxidation reaction (FAOR). The fct-FePtAu nanoparticles show high CO poisoning resistance, achieve mass activity as high as about 2810 mA/mg Pt, and retain greater than 90% activity after a 13 hour stability test.
