  • Patent number: 8821958
    Abstract: A method for electrostatic coating of medical devices such as stents and balloons is described. The method includes applying a composition to a polymeric component of a medical device which has little or no conductivity. The polymeric component could be a material from which the body or a strut of the stent is made or could be a polymeric coating pre-applied on the stent. The polymeric component could be the balloon wall. A charge can then be applied to the polymeric component or the polymeric component can be grounded. Charged particles of drugs, polymers, biobeneficial agents, or any combination of these can then be electrostatically deposited on the medical device or the coating on the medical device. One example of the composition is iodine, iodine, iodide, iodate, a complex or salt thereof which can also impart imaging capabilities to the medical device.

    Abstract: A method for modifying surface charges created by contact electrification includes providing a polymer formed of a plurality of monomers each containing a functional group capable of reversibly switching between a first structure and a second structure different from the first structure, the functional group having the first structure; contact-charging the polymer with a surface such that the polymer carries a first net surface charge; and converting the first structure of the functional group to the second structure. The sequence of the contact-charging and converting steps can be switched.

  • Publication number: 20130280437
    Abstract: Apparatus and method for electrostatic charging of a container for an electrostatic coating operation includes a support member for supporting a container during an electrostatic coating operation with the support member comprising a non-metallic conductive material or electrically semiconductive portion that directly contacts a surface of the container. The electrically semiconductive portion comprises non-metallic, resistive or low conductivity material and is coupled to a source of electrical energy such that the container is electrostatically charged to an opposite polarity to offset or reduce electrostatic charge build up produced by the electrostatic coating operation.

  • Publication number: 20130280436
    Abstract: A method comprises: dissolving an aromatic side chain polymer in a terpene, terpenoid, or aromatic solvent; dissolving an inorganic salt in a polar organic solvent; mixing the salt solution and the polymer solution; and using a predominantly terpene, terpenoid, or aromatic solvent phase of the mixture as electrospinning fluid. The fluid is electrospun from spinning tip(s) onto a target substrate. The inorganic salt and the polar organic solvent are chosen so as not to cause substantial precipitation of the polymer upon mixing with the polymer solution. The terpene, terpenoid, or aromatic solvent can comprises D-limonene, the aromatic side chain polymer can comprise polystyrene, the polar organic solvent can comprise dimethyl formamide, and the inorganic salt can comprise LiCl, AgNO3, CuCl2, or FeCl3. The method can further comprise electrospinning the fluid with the fluid and spinning tips electrically isolated from a voltage source that drives the electrospinning.

  • Patent number: 8557758
    Abstract: Compositions, methods, apparatuses, kits, and combinations are described for applying a colorant to a surface. Compositions are formulated to be applied and affixed to a surface. The compositions may be substantially removed from the surface to remove a portion or substantially all of a stain before being affixed to the surface. The compositions are formulated to be removed by a number of methods including, for example, vacuuming, wet extraction, chemical application, and the like. Compositions may be permanently or semi-permanently affixed to the surface by applying energy thereto in the form of, for example, heat, pressure, emitted waves, an emitted electrical field, a magnetic field, and/or a chemical. The compositions may also be utilized in the form of a kit or in conjunction with a design device, such as a stencil, to control the application of the composition to create, for example, a pattern on the surface.

  • Patent number: 8551577
    Abstract: Disclosed is a method of applying particles to a coated backing. A first layer of particles is created over a second layer of particles on a support surface and the first layer of particles is different in at least one property from the second layer of particles. A coated backing is positioned above the first and second layer of particles. An electrostatic field is applied simultaneously to the first and second layer of particles such that the first layer of particles closer to the coated backing are preferentially attracted to the coated backing first before the second layer of particles.

  • Publication number: 20130260051
    Abstract: A method of manufacturing a ferroelectric thin film on a lower electrode by electrostatically spraying a ferroelectric thin film-forming sol-gel solution from a spout of a capillary toward the lower electrode of a substrate having the lower electrode so as to coat the sol-gel solution on the lower electrode and form a coated film, drying, calcining, and then firing the coated film so as to crystallize the coated film, in which a distance between the spout of the capillary and the lower electrode and an applied voltage during electrostatic spray are set so that a refractive index during drying and calcination of the coated film becomes 2 or more, and a film thickness sets in a range of 150 nm or less when the sol-gel solution is coated in a single spray process, calcined, and then fired so as to be crystallized.

  • Publication number: 20130260050
    Abstract: The invention has been based on original way of surface modification of solid substrates for efficient phosphorylated peptide preconcentration from complex peptide mixtures prior to detection based on desorption/ionization mass spectrometry. The subject of protection is the method of surface functionalization by ambient ion landing. The approach was based on electronebulization (electrospray) of solutions of organometallic compounds related to elements of 4B class of periodic table of elements, especially to zirconium, hafnium and titanium. The generated charged electrospray was dried on the fly by passing the heated compartment and focused to a surface forming a stable oxide layer there. The surface modified this way has been used for phosphopeptide enrichment from peptide mixtures prior to desorption/ionization mass spectrometry.
