  • Patent number: 11942878
    Abstract: A microstructured device is disclosed utilizing Coulomb field modification of surface energy and electroadhesion to localize a device surface or to levitate a device surface with respect to a target surface. The surface energy modification can be permanent or reversible depending on whether the charge is externally delivered to the device or derived on the device galvanically. The microstructure aspect of the device induces various hydrophilic/hydrophobic interactions with the target surface. The Coulomb field can be used to enhance or decrease the hydrophilic/hydrophobic interactions. In combination, the disclosed electro-microstructured device provides for localizing implants in a mammalian body, and additionally means for controlling cell interaction with the implant.

    Abstract: Disclosed is a method for manufacturing a flat liquid crystal display device film. According to the method for manufacturing the flat liquid crystal display device film, influence of a wiring thickness on topography of array film can be reduced. Without affecting a qualified rate of a product, a low-resistance wiring can be realized, and thus an RC delay during signal transmission of a large-sized panel can be reduced. Meanwhile, when the method is applied, a metal layer with a larger thickness relative to that of a metal layer made by a conventional method can be made. Therefore, wiring load of a large-sized panel can be reduced, resistance of signal line can be reduced. RC delay can be decreased, and display quality can be improved.

    Abstract: The present invention provides a patterned polarization converter having multiple domains that can be used to convert input linear polarized light to output light with spatially varying polarization states, including domains that produce linearly polarized light and domains that produce circular polarized light based on the patterning of the domains. A patterned polarization converter having multiple domains may be used in a polarization sensor application capable of detecting the polarization state of input light. The present invention further provides patterned radial and azimuthal polarization converters, which have utility in applications such as optical tweezers. Additionally, patterned polarization converters may be used to fabricate more patterned polarization converters having the same pattern using one-step photoalignment to copy the pattern of an existing patterned polarization converter to an unpatterned photoalignment layer.

  • Publication number: 20150056410
    Abstract: A process for application of metal on a substrate surface comprises applying a mixture of a solvent, a polymerizable monomer, and a photoinitiator on a substrate surface, wherein the photoinitiator does not form two phases together with the monomer and the solvent, i.e. it forms an amorphous mixture without any crystals. The monomer is able to polymerize to a polymer comprising at least one carboxylic group. Thereafter the solvent is evaporated. Polymerization is induced by irradiating the applied dried mixture. Ions are applied and reduced to metal and thereafter further metal can be deposited. The method can be used in industrial processes, both 2D and 3D surfaces can be coated with metal. Materials sensitive to standard grafting chemicals and/or polymers containing halogen atoms can be coated.

  • Patent number: 8956696
    Abstract: A method for forming an ultra-thin membrane for use in a chemical analyzer such as a mass spectrometer includes the step of applying a sacrificial blocking layer onto a porous substrate, applying a semi-permeable membrane layer onto the sacrificial blocking layer, and removing the sacrificial blocking layer following cure of the membrane layer. In a preferred version, at least one of the blocking layer and the membrane layer are applied to the porous support by means of spin coating, though other deposition techniques can be employed.

  • Patent number: 8956563
    Abstract: A molding method includes drawing cross-section elements of a three-dimensional object as a molding target on a drawing surface of a drawing stand with a liquid whose curing is precipitated by receiving activation energy as cross-section patterns; applying the activation energy to the liquid configuring the cross-section patterns in a state in which the cross-section patterns is pinched between the drawing stand and a molding stand; and detaching the cross-section patterns after being applied with the activation energy from the drawing stand and transferring the cross-section patterns to the molding stand side, wherein the drawing surface has a liquid repellent area that is an area representing liquid repellency for the liquid and a lyophilic area that is independently formed in an island shape within the liquid repellent area and is an area representing lyophillicity stronger than that of the liquid repellent area for the liquid.

    Abstract: Microwave energy interactive material is partially coated with thermoset polymeric material. The thermoset polymeric material is cured on a first portion of the microwave energy interactive material. A second portion of the microwave energy interactive material is neither covered by nor protected by the cured thermoset polymeric material. A deactivating agent is applied to the coated microwave energy interactive material, so that the agent deactivates the second portion of the microwave energy interactive material into a microwave energy transparent area. The cured thermoset polymeric material protects the first portion of the microwave energy interactive material from the agent, so that it remains microwave energy interactive.
