Patent number: 8728621Abstract: The present invention provides a hard multilayer film formed body which has an intermediate layer excellent in its adhesion to a base material and a DLC film which is a surface layer excellent in its wear resistance, prevents peeling from occurring between the DLC film and the intermediate layer, and is excellent in its wear resistance and a method for producing the same. A hard multilayer film formed body 1 consists of a multilayer film formed on a surface of a base material 2 consisting of a cemented carbide material or a ferrous material. The multilayer film has (1) a film, composed mainly of DLC, which is formed as a surface layer 5 of the multilayer film; (2) an intermediate layer 3, composed mainly of a metallic material, which is formed between the surface layer 5 and the base material 2; and (3) a stress relaxation layer 4, composed mainly of carbon, which is formed between the intermediate layer 3 and the surface layer 5.Type: GrantFiled: October 29, 2009Date of Patent: May 20, 2014Assignee: NTN CorporationInventors: Kouya Oohira, Naoko Ito, Yoji Sato, Hideyuki Tsutsui

Publication number: 20140134439Abstract: A method for solvent-less adhesive bonding is provided comprising depositing thin, functional, polymeric films on one or more substrates and bonding the substrates to each other or to other substrates. Depositing the polymeric films, including, for example, chemically reactive polymers and thermoplastics with adhesive qualities, may be accomplished using an initiated chemical vapor deposition technique compatible with a variety of monomers, including monomers with chemically functional moieties such as amine and epoxy groups. The technique allows for deposition of polymeric films on a wide variety of substrates/devices and provides an alternative for other coating/deposition methods that are incompatible with certain substrates/devices and/or do not provide adequate control over the resulting polymeric film. The provided method is advantageous in that it is applicable to fabrication of hybrid devices and is compatible with microfabrication technology, including that in clean-room settings.Type: ApplicationFiled: November 12, 2013Publication date: May 15, 2014Applicant: The Research Foundation for the State University of New YorkInventor: Magnus Bergkvist

Publication number: 20140130969Abstract: New temporary bonding methods and articles formed from those methods are provided. In one embodiment, the methods comprise coating a device or other ultrathin layer on a growth substrate with a rigid support layer and then bonding that stack to a carrier substrate. The growth substrate can then be removed and the ultrathin layer mounted on a final support. In another embodiment, the invention provides methods of handling device layers during processing that must occur on both sides of the fragile layer without damaging it. This is accomplished via the sequential use of two carriers, one on each side of the device layer, bonded with different bonding compositions for selective debonding.Type: ApplicationFiled: July 9, 2012Publication date: May 15, 2014Applicant: BREWER SCIENCE INC.Inventors: Jeremy McCutcheon, Tony D.

Publication number: 20140127490Abstract: An aerogel fabricated by forming an aqueous suspension including carbon nanotubes and a surfactant, agitating the aqueous suspension, and centrifuging the agitated suspension to form a supernatant including the carbon nanotubes. The supernatant is concentrated to form a concentrated suspension including the carbon nanotubes, and a hydrogel is formed from the concentrated suspension. The hydrogen is contacted with a strong acid to form an acidic hydrogel and to remove surfactant from the hydrogel, and then neutralized. An aerogel is formed from the hydrogel. The aerogel may consist essentially of carbon nanotubes. A composite may be formed from the hydrogel or the aerogel by infiltrating the hydrogel or the aerogel with a polymeric material and curing or pyrolyzing the polymeric material. The composite may be electrically conductive, transparent, flexible, superelastic, or any combination thereof. A device, such as a flexible conductor, sensor, or electrode may include the aerogel or the composite.Type: ApplicationFiled: April 4, 2012Publication date: May 8, 2014Applicant: CARNEGIE MELLON UNIVERSITYInventors: Mohammad F.
