Abstract: The present invention relates to a method for manufacturing a module type microfluidic chip comprising: (a) printing electrode patterns on a substrate using a conductive ink and inkjet printing; (b) cutting the printed electrode patterns; and (c) assembling the cut electrode patterns to manufacture the module type microfluidic paper chip. Unlike the traditional method for manufacturing printed circuit substrate using a patterning agent or device, the method of the present invention only incorporates a simple printing process using an inkjet printer, and thus patterning can be simplified and various types of chips can be manufactured depending on the assembly type of electrode patterns. Accordingly, inexpensive, economical, and highly utilizable microfluidic chips can be provided using the method of the present invention.

Abstract: An introduction arrangement for a fenestrated or branched stent graft (13) intended for deployment into the lumen of a vessel having a blind vessel extending from it. The introducer (1) has a distal end intended to remain outside a patient in use and a proximal end with a nose cone dilator (11) and an arrangement to retain the branched stent graft distally of the nose cone dilator. A sheath (15) on the introducer extends over the branched stent graft to the nose cone dilator. An indwelling catheter (21) extends from the distal end of the introducer and enters the fenestration or side arm and through to the nose cone dilator, the indwelling catheter has a guide wire (29) extending through it. The guide wire can be extended beyond the nose cone dilator in use before the sheath is withdrawn from the branched stent graft so that it can be snared from the contra-lateral artery.

Abstract: A semiconductor stacking structure according to the present invention comprises: a monocrystalline substrate which is disparate from a nitride semiconductor; an inorganic thin film which is formed on a substrate to define a cavity between the inorganic thin film and the substrate, wherein at least a portion of the inorganic thin film is crystallized with a crystal structure that is the same as the substrate; and a nitride semiconductor layer which is grown from a crystallized inorganic thin film above the cavity. The method and apparatus for separating a nitride semiconductor layer according the present invention mechanically separate between the substrate and the nitride semiconductor layer. The mechanical separation can be performed by a method of separation of applying a vertical force to the substrate and the nitride semiconductor layer, a method of separation of applying a horizontal force, a method of separation of applying a force of a relative circular motion, and a combination thereof.

Abstract: A shape-memory self-healing polymeric network (SMSHP) is useful as a molded part, a coating, or as a matrix for a composite that can be repaired by heating to a controlled temperature. The SMSHP has thermally reversible repeating units where a thermally reversible adduct is situated between two common linking units formed during a polymerization process between thermally reversible monomers and cross-linking monomers. Optionally, other repeating units can be present from other monomers. Shape-memory results when the SMSHP is warmed to a temperature in excess of its glass transition temperature and self-healing then proceeds when a higher temperature is achieved where thermally reversible adducts dissociates to complementary groups that subsequently reform the adduct without distortion of the memorized shape. The thermally reversible adducts can be Diels-Alder (DA) adducts in a polyurethane, poly urea, or amine epoxy SMSHP network.

Abstract: A method and device for harvesting and storing solar energy is provided. The device converts solar energy to electrical energy via the photovoltaic effect. The device includes a pair of electrodes, at least one of which is transparent to allow solar energy to pass through. A medium is disposed between the electrodes which exhibits a combination of photovoltaic and ferroelectric properties. When solar energy passes through the transparent electrode and is received by the medium, electron-hole pairs establish a voltage potential between electrodes in the device via the photovoltaic effect. The voltage potential may be retained and the mobile charge may be stored in the absence of solar energy via the ferroelectric effect.
