  • Publication number: 20150037802
    Abstract: The present invention provides a novel method to fabricate silica nanostructures on thin polymer films based on silica deposition and self-wrinkling induced by thermal shrinkage. These micro- and nano-scale structures have vastly enlarged the specific area of silica, thus the silica nanomembranes can be used for solid phase extraction of nucleic acids. The inventive silica nanomembranes are suitable for nucleic acid purification and isolation and demonstrated better performance than commercial particles in terms of DNA recovery yield and integrity. In addition, the silica nanomembranes have extremely high nucleic acid capacity due to its significantly enlarged specific surface area of silica. Methods of use and devices comprising the silica nanomembranes are also provided.

    Abstract: A method of fabricating a liquid film is provided. The method comprises the steps of applying hydrophilic liquid onto a substrate with an electrode formed thereunder, covering the hydrophilic liquid with a protection film comprising hydrophobic liquid, dispersing surfactant for reducing the surface tension between the hydrophilic liquid and the protection film, and applying voltage to the hydrophilic liquid and the electrode to wet the substrate with the hydrophilic liquid. With the surfactant and the electro-wetting principle, a contact angle between the hydrophilic liquid and the substrate is controlled. The liquid film having a uniform thickness in nano size is thus formed on the substrate. The protection film prevents the evaporation of the liquid film in the air to thereby secure the stability of the liquid film.

  • Patent number: 7008522
    Abstract: A method of locally repairing parts coated with a thermal barrier including a ceramic outer layer and a metal underlayer of alumina-forming alloy for protecting the substrate against oxidation and for bonding with the ceramic outer layer, includes: defining the zone for repair with a mechanical mask adapted to the shape of the part and the zone for repair; scouring the zone for repair so as to remove the ceramic, the alumina layer, and the damaged portions of the underlayer; supplying materials for repairing the underlayer to the repair zone by subjecting the partially-scoured part to metal deposition by use of an electrical current; and subjecting the part to a heat treatment in order to enable the added metals to diffuse into the remaining underlayer in the repair zone for repair and to enable a surface film of alumina to form. After the underlayer has been reconstituted, the zone for repair is again defined by a mechanical mask and a new ceramic layer is deposited thereon.

  • Publication number: 20040238363
    Abstract: The present invention relates to a device and to a method for coating bicycle components. According to the invention, the device has at least one power supply unit, at least one liquid tank and at least one conveying means for the bicycle components to be coated. On the power supply unit, there are at least two electrodes that are connected to the bicycle components and arranged in the liquid tank. In the liquid tank, there is also a carrier solution having a prescribed proportion of a coating substance, where the electric circuit to the power supply unit is closed when at least one component is at least partially brought into contact with the liquid. The coating substance is deposited at least as a function of a prescribed electric current.

  • Patent number: 6607645
    Abstract: The present invention provides methods for producing hollow ceramic membranes by electrophoretic deposition. The hollow ceramic membranes may have a small cross-sectional area of about 1.0×10−5 mm2 to about 25 mm2. The cross-sectional configuration of the hollow ceramic membranes may be any geometry such as circular, square, rectangular, triangular or polygonal. The hollow ceramic membranes produced by the methods of the present invention may have multiple layers but always the innermost layer, or the first deposited layer is porous and made by electrophoretic deposition. Subsequent layers may be porous or non porous and deposited before or after sintering the first layer. If it is deposited after sintering, it may require additional sintering steps. Additional layers may be deposited by further electrophoretic deposition, sol-gel coating, dip coating, vacuum casting, brushing, spraying or other known techniques.

  • Patent number: 6508922
    Abstract: A process for the production of a multi-layer coating, wherein a primer layer which is electrically conductive in the at least partially cured state is applied by electrodeposition from an electrodeposition coating agent (I) to an electrically conductive three-dimensional object, at least partially cured exclusively by the action of near infra-red radiation substantially only on the surfaces of the object exposed to the radiation, and an additional coating layer is applied by electrodeposition from an electrodeposition coating agent (II) which is different from electrodeposition coating agent (I), and then this additional coating layer as well as completely uncured or incompletely cured area parts of the primer layer produced from electrodeposition coating agent (I) are cured.
