  • Patent number: 8816012
    Abstract: An acrylate-based curable printing medium is disclosed. Acrylates, in the form of monomers, dimers, trimers and oligomers, as well as resins, form an interpenetrating polymer network by crosslinking, which is effected by heat, and optionally peroxide curing agents. Formulations can be tailored to achieve desired properties of the cured polymer including film hardness, burnout properties, and adhesion to glass. Such properties are adjusted by manipulating the relative proportions of the acrylic monomers, oligomers and resins that are used as a ceramic medium or vehicle.

  • Patent number: 8786034
    Abstract: Hot-melt sealing glass compositions that include one or more glass frits dispersed in a polymeric binder system. The polymeric binder system is a solid at room temperature, but melts at a temperature of from about 35° C. to about 90° C., thereby forming a flowable liquid dispersion that can be applied to a substrate (e.g., a cap wafer and/or a device wafer of a MEMS device) by screen printing. Hot-melt sealing glass compositions according to the invention rapidly re-solidify and adhere to the substrate after being deposited by screen printing. Thus, they do not tend to spread out as much as conventional solvent-based glass frit bonding pastes after screen printing. And, because hot-melt sealing glass compositions according to the invention are not solvent-based systems, they do not need to be force dried after deposition.

  • Patent number: 8691332
    Abstract: A silver conductive coating possessing infrared absorbing properties is disclosed. The coating is made from a blend of one or more micron size silver powders and/or flakes together with carbon black, inorganic pigment, glass frit, and powdered selenium or bismuth metal. The foregoing dry ingredients are pasted with an organic vehicle, applied to a substrate, and fired at a temperature of up to 1400° F. The coating absorbs infrared radiation beyond the decomposition of carbon black, thus allowing higher firing temperatures and hence shorter firing times.

  • Patent number: 8642091
    Abstract: A method of producing solid composite lipid/drug nanoparticles that includes the steps of: (1) dissolving a lipid and a drug in a suitable organic solvent to form a solution; (2) emulsifying the solution in a liquid to form an emulsion having a discontinuous phase of micelles comprising the organic solvent, the drug and the lipid, and a continuous phase comprising the liquid; and (3) contacting the emulsion with a supercritical fluid under conditions suitable to keep the supercritical fluid in a supercritical state, whereby the supercritical fluid extracts the organic solvent from the micelles, causing them to precipitate as organic-solvent free solid composite lipid/drug nanoparticles suspended or dispersed in the liquid.

  • Patent number: 8535720
    Abstract: The present invention provides methods and apparatus for producing particles via supercritical fluid processing. In one embodiment, the method includes expanding a supercritical fluid plasticized melt across a pressure drop to form solid composite particles that are simultaneously dispersed, foamed and cooled, and milling the solid particles produced to achieve the desired size distribution. In another embodiment, a pressure vessel containing a supercritical fluid plasticized melt is depressurized to form a cooled solid porous mass, which is then milled to obtain solid composite particles.
