  • Publication number: 20100227947
    Abstract: The present disclosure is drawn to methods and compositions directed at encapsulated pigments. As such, an encapsulated pigment can comprise a pigment and a polymer encapsulating the pigment, where the polymer comprises a monomer and a RAFT reagent. Additionally, a method of encapsulating pigments can comprise dispersing a pigment in an aqueous solution to form a pigment dispersion, adding a monomer to the pigment dispersion, adding a RAFT reagent to the pigment dispersion, and polymerizing the monomer using the RAFT reagent in the presence of the pigment to form an encapsulated pigment. Further, the present disclosure provides ink-jet inks comprising the encapsulated pigments.

  • Patent number: 7790074
    Abstract: A method of forming a three-dimensional object comprises ejecting drops of liquefied material into a vat using an ejector; scanning the ejector in first and second mutually opposed directions to induce the drops of liquefied material from the ejector to deposit and solidify in a predetermined sequence to sequentially form layers of the three-dimensional object; supplying a viscous liquid into the vat to a level which is essentially level with the top of a most recently formed layer of the three-dimensional object; and raising the level of the viscous liquid in accordance with the formation of new layers.

  • Patent number: 7445742
    Abstract: A method and mold for creating nanoscale patterns in an ion-selective polymer membrane is provided, in which a mold comprising a substrate and a molding layer having at least one protruding feature is imprinted on the ion-selective polymer membrane, thereby creating a recessed feature in the membrane. Protruding features having nanoscale dimensions can be created, e.g., by using self-assembled nanostructures as a shadow mask for etching a molding layer. In one embodiment, an imprinted ion selective polymer membrane, suitable for use as a solid electrolyte, is adapted for use in an electrochemical device or fuel cell by adding a metal catalyst to one portion of the membrane to serve as a catalytic electrode.

  • Patent number: 6869712
    Abstract: A method for roughening a surface of an ion exchange system structure using laser interaction with a surface. The laser surface roughening process allows the use of a wide range of substrates such as metals, ceramics, silicates, polymers and the like, including varieties which can not be fabricated in a fine fibrous structure. The surface roughened ion exchange system structure may be used as an ion-exchange media in applications such as fuel cells, batteries, and other catalysis systems where a high surface exchange area is desirable.

  • Patent number: 6777172
    Abstract: A method for using an excimer laser to pattern electrodeposited photoresist on a sloped surface of a wafer substrate includes depositing a layer of photoresist on top of a substrate that includes a sloped surface and scanning an excimer laser beam over the layer of photoresist to expose the layer of photoresist in a desired pattern. The scanning step includes projecting the excimer laser beam in a small beam spot onto the substrate and scanning the small beam spot of the excimer layer beam relative to the substrate to define the pattern sequentially onto the substrate, including the sloped surface.

  • Patent number: 6033628
    Abstract: In a method of forming a microchannel and/or microcavity structure by bonding together two elements (1, 2) having opposed plane surfaces of the same or different material, one or both surfaces having open channels and/or cavities, bonding is effected by applying to one or both element surfaces (1, 2) a thin layer (3) of a solution of a material capable of fusing with and having a lower melting point than that of the material or materials of the two element surfaces (1, 2) in a solvent which substantially does not dissolve the element surface material or materials. The solvent is then removed, and the two elements (1, 2) are brought together and heated to a temperature where the dissolved material is caused to melt but not the element surface material or materials.
