  • Patent number: 10847309
    Abstract: A formed body incorporating a coil by using: a coil formed by winding a conductive wire, and a formed body incorporating the coil, the formed body being formed with a sealing material containing a resin and a magnetic material. The coil is formed by winding the conductive wire so that lead-out ends are positioned at an outer periphery of a wound portion. The formed body is formed so that surfaces of the coil are partially exposed on four side surfaces of the formed body which are parallel to a winding axis of the coil, and the area of a portion of the formed body outside the outer periphery of the wound portion is almost equal to or smaller than the area of a portion of the formed body inside an inner periphery of the wound portion of the coil.

  • Patent number: 10092661
    Abstract: In the present invention, a method of producing stable bare colloidal gold nanoparticles is disclosed. The nanoparticles can subsequently be subjected to partial or full surface modification. The method comprises preparation of colloidal gold nanoparticles in a liquid by employing a top-down nanofabrication method using bulk gold as a source material. The surface modification of these nanoparticles is carried out by adding one or multiple types of ligands each containing functional groups which exhibit affinity for gold nanoparticle surfaces to produce the conjugates. Because of the high efficiency and excellent stability of the nanoparticles produced by this method, the fabricated gold nanoparticle conjugates can have surface coverage with functional ligands which can be tuned to be any percent value between 0 and 100%.

  • Publication number: 20160158155
    Abstract: Disclosed is process for preparing magnetic nanoparticles (MNPs) that results in very sensitive MNPs that can be used in a variety of diagnostic and analytical methods. The MNPs exhibit superparamagnetism and find special use in giant magnetoresistance sensors (GMRS). The MNPs are created by a process that permits one to tune the size of nanoparticles to a range of from 10 to 20 nanometers with a very small particle size distribution of +/?2 nanometers or less. The MNPs can be tagged with a variety of markers and thus find use in many analytical assays, cell sorting techniques, imaging methods, drug delivery methods and cancer treatments. The inventive MNPs can be detected in magnetic file strengths of 2000 Oe or less.

  • Patent number: 8802234
    Abstract: A composite nanoparticle, for example a nanoparticle containing one or a plurality of cores embedded in another material. A composite nanoparticle can be formed by a one step process that includes: ejecting material from a bulk target material using physical energy source, with the bulk target material disposed in a liquid. Composite nanoparticles are formed by cooling at least a portion of the ejected material in the liquid. The composite fine particles may then be collected from the liquid. A product that includes composite fine particles may be formed with laser ablation, and ultrashort laser ablation may be utilized so as to preserve composite nanoparticle stoichiometry. For applications of the composite fine particles, optical properties and/or magnetic properties may be exploited for various applications.

  • Publication number: 20140161998
    Abstract: A method of forming patterns on transparent substrates using a pulsed laser is disclosed. Various embodiments include an ultrashort pulsed laser, a substrate that is transparent to the laser wavelength, and a target plate. The laser beam is guided through the transparent substrate and focused on the target surface. The target material is ablated by the laser and is deposited on the opposite substrate surface. A pattern, for example a gray scale image, is formed by scanning the laser beam relative to the target. Variations of the laser beam scan speed and scan line density control the material deposition and change the optical properties of the deposited patterns, creating a visual effect of gray scale. In some embodiments patterns may be formed on a portion of a microelectronic device during a fabrication process. In some embodiments high repetition rate picoseconds and nanosecond sources are configured to produce the patterns.
