    Abstract: A carbon nanotube is contacted with a reactive substance which is a metal or a semiconductor. The reactive substance is heated to diffuse atoms of the reactive substance into the carbon nanotube so that the carbon nanotube is partially transformed or converted into carbide as a reaction product. Thus, a heterojunction of the reaction product and the carbon nanotube is formed. For example, the carbon nanotube (2) is contacted with a silicon substrate (1). The silicon substrate (1) is heated to cause solid-solid diffusion of Si. As a result, SiC (3) is formed as the heterojunction.

  • Patent number: 6146482
    Abstract: A method for making a reinforced pipeline comprising determining the thicknesses of a metallic liner and a reinforcement which are effective to limit stresses on a reinforced pipeline at a known operating pressure to a known percentage of the specified minimum yield strength and a known percentage of at least one actual yield strength along the length of the pipeline which differs from the specified minimum yield strength. Preferably, the reinforced pipeline is pressurized to produce yielding which results in a residual stress pattern effective to resist ductile fracture propagation along a longitudinal axis of said metallic liner along a length of the pipeline comprising at least two actual yield strengths.

  • Patent number: 6136393
    Abstract: A container for holding a floral grouping. The container, most generally a vase, is formed from a sheet of material and has an outer peripheral wall which extends from the closed lower end to the open upper end. The peripheral wall may comprise a plurality of folds in the sheet of material with adjacent portions of at least some of the folds, which connected via a bonding material to form connected folds, which connected folds cooperate to maintain the vase in the shape of a vase. The container preferably has a bonding material disposed on a portion of the surface of the vase for enabling the vase to be bondingly connected to a surface in a vertical orientation.

  • Patent number: 6117545
    Abstract: Cellulose microfibrils, in particular for use as a reinforcing filler or structuring agent in composite materials, a method for making same, and composite materials containing said microfibrils, are disclosed. Specifically, said microfibrils are surface-modified cellulose microfibrils with an L/D ratio higher than 20, preferably higher than 100, and an average diameter of 1-50 nm, where L is the length of the microfibril and D is its average diameter. At least 25% by number of the hydroxyl functions on the surface of the microfibrils are esterified by at least one organic compound including at least one function capable of reacting with the hydroxyl groups of the cellulose. As a result, when the organic compound is a compound that includes acetyl groups such as acetic acid, said microfibrils are used as a reinforcing filler in a material comprising cellulose acetate as the polymeric matrix. The filled composite material may be shaped to provide films, moldings, fibers or yarns.

  • Patent number: 6103341
    Abstract: A partition for forming a barrier in a channel has a molded resin-based plate and a plurality of thermally expandable pellets attached to one side of the plate. The partition is secured in place in the channel by mounting brackets. As heat is applied, a blowing agent in the pellets is activated and the pellets expand to many times their original volume. The resultant foam seals the gap between the plate and the surrounding structure and further secures the plate in place. The partition is particularly useful in forming a sound/water/air barrier in an automotive cavity.
