  • Patent number: 11104800
    Abstract: The present disclosure relates to a resin composition for vehicle parts, a vehicle part manufactured using the resin composition, and a method of manufacturing the vehicle part. Ultra-high molecular weight siloxane and an inorganic filler are mixed with an alloy resin of polyamide and polyethylene at an optimal rate in order to improve friction resistance and wear resistance while maintaining excellent impact resistance and low hygroscopicity. When a vehicle part is manufactured using the resin composition, it is possible to eliminate the application of silicone-based oil or to remarkably reduce the amount of silicone-based oil that is used, whereby it is possible to reduce manufacturing costs. Furthermore, ingredients that are harmful to human beings, such as POM, are not included, whereby it is possible to improve the quality of air in a vehicle.

  • Patent number: 10519051
    Abstract: A system has been developed to treat ballast water by selectively dissociating target molecules into component products compositionally distinct from the target molecule, wherein the bonds of the target molecule do not reform because the components are no longer reactive with each other. Dissociation is affected by treating the target molecule with light at a frequency and intensity, alone or in combination with a catalyst in an amount effective to selectively break bonds within the target molecule. Dissociation does not result in re-association into the target molecule by the reverse process, and does not produce component products which have a change in oxidation number or state incorporated oxygen or other additives because the process does not proceed via a typical reduction-oxidation mechanism.

A portion of the fill material adsorbs onto the structures under measurement and fills openings in the structural features, spaces between structural features, small volumes such as notches, trenches, slits, contact holes, etc. In one aspect, the desired degree of saturation of vaporized material in the gaseous flow is determined based on the maximum feature size to be filled. In one aspect, measurement data is collected when a structure is unfilled and when the structure is filled by gaseous adsorption. The collected data is combined in a multi-target model based measurement to reduce parameter correlations and improve measurement performance.

Reducing the number of process steps, and eliminating lithography steps, in localized material removal has the dual benefit of reducing manufacturing cycle time and increasing yield by lowering the probability of defect introduction. Furthermore, highly localized, precision material removal allows for controlled variation of removal rate and enables creation of 3D structures or profiles. Local gas injectors and detectors, and local photon injectors and detectors, are local to corresponding ones of the columns, and can be used to facilitate rapid, accurate, targeted substrate processing.

  • Publication number: 20140224642
    Abstract: Electromagnetic irradiation of functionalized fullerenes in an oxygen-free environment induces conversion of the functionalized fullerenes to carbon nanotubes, carbon nanohorns, carbon onions, diamonds and/or carbon schwarzites. The carbon nanotubes can be multi-wall carbon nanotubes. Advantageously, the subject invention can be used for in-situ synthesis of carbon nanostructures within a matrix to form a carbon nanostructure composite, where positioning of the carbon nanostructures is controlled by the manner of dispersion of the functionalized fullerenes in the matrix. Carbon nanotube comprising features, such as electrical connects, can be formed on a surface by irradiating a portion of a functionalized fullerene coating with a laser beam.

  • Patent number: 8742334
    Abstract: A spinning cell device is described for fast and convenient standardization and analysis of constituents and isotopes in solid samples by laser ablation inductively coupled plasma (LA-ICP) spectrometry. The method and apparatus for performing the method require the sample under test and a standard to be spun during ablation allowing the quasi-simultaneous ablation of both materials. The aerosols resulting from the ablation of sample and standard are mixed in the ablation cell allowing quantification of the ablated metals by the method of standard addition or isotope dilution. The relative proportion of standard verses sample ablated can be changed by altering the trajectory of the laser beam. The ablated aerosol is swept into an inductively coupled plasma by a carrier gas and analyzed by mass spectrometry.

    Abstract: A sheet material has structures of graphene oxide and graphene in which the graphene oxide and the graphene are chemically connected and coexist to form a plane such that the plane is divided into a region of the graphene oxide and a region of the graphene. A method of reduction of graphene oxide includes providing a sheet material having at least one atomic layer of graphene oxide and a femtosecond laser apparatus that can emit a femtosecond laser shot in a controlled manner. A pulse shape and intensity of an electric field formed by the laser shot are tuned so that the laser shot can be emitted onto a region of the graphene oxide sheet in a controlled manner to selectively cause reduction of the graphene oxide of the region.

  • Patent number: 8337673
    Abstract: The invention relates to the synthesis of silicon-containing nanoparticles by laser pyrolysis. For this purpose: a precursor (SiH4) containing the element silicon is conveyed, by a transport fluid (He), into a pyrolysis reactor (REAC); laser radiation (LAS) is applied, in the reactor, to a mixture that the transport fluid and the precursor form; and silicon-containing nanoparticles (nP) are recovered at the exit of the reactor. In particular, the power of the laser radiation is controlled. Furthermore, the effective pulse duration is controlled within a laser firing period. Typically, for a power greater than 500 watts and a pulse duration greater than 40% of a laser firing period, nanoparticles having a crystalline structure with a size of less than or of the order of one nanometer are obtained at a rate greater than or of the order of 80 milligrams per hour. Under optimum conditions, a record rate of greater than 740 milligrams per hour was able to be obtained.

  • Patent number: 8317983
    Abstract: Single walled carbon nanotubes are produced in a novel apparatus by the laser-induced ablation of moving carbon target. The laser used is of high average power and ultra-fast pulsing. According to various preferred embodiments, the laser produces and output above about 50 watts/cm2 at a repetition rate above about 15 MHz and exhibits a pulse duration below about 10 picoseconds. The carbon, carbon/catalyst target and the laser beam are moved relative to one another and a focused flow of “side pumped”, preheated inert gas is introduced near the point of ablation to minimize or eliminate interference by the ablated plume by removal of the plume and introduction of new target area for incidence with the laser beam. When the target is moved relative to the laser beam, rotational or translational movement may be imparted thereto, but rotation of the target is preferred.
