  • Publication number: 20090242417
    Abstract: A process for manufacturing electrodes for electrolysis, including steps of forming an arc ion plating (AIP) undercoating layer including valve metal or valve metal alloy containing a crystalline tantalum component and a crystalline titanium component on a surface of the electrode substrate comprising valve metal or valve metal alloy, by an arc ion plating method; heat sintering, including the steps of coating a metal compound solution, which includes valve metal as a chief element, onto the surface of the AIP undercoating layer, followed by heat sintering to transform only the tantalum component of the AIP undercoating layer into an amorphous substance, and to form an oxide interlayer, which includes a valve metal oxides component as a chief element, on the surface of the AIP undercoating layer containing the transformed amorphous tantalum component and the crystalline titanium component; and forming an electrode catalyst layer on the surface of the oxide interlayer.

  • Publication number: 20080248427
    Abstract: The present invention relates to an aqueous coating composition for coating a photoresist pattern comprising a polymer containing a lactam group of structure (1) where R1 is independently selected hydrogen, C1-C4 alkyl, C1-C6 alkyl alcohol, hydroxy (OH), amine (NH2), carboxylic acid, and amide (CONH2), represents the attachment to the polymer, m=1-6, and n=1-4. The present invention also relates to a process for manufacturing a microelectronic device comprising providing a substrate with a photoresist pattern, coating the photoresist pattern with the novel coating material reacting a portion of the coating material in contact with the photoresist pattern, and removing a portion of the coating material which is not reacted with a removal solution.

  • Publication number: 20070005139
    Abstract: Connective tissue, including neo-tendons and ligaments, has been constructed using biodegradable synthetic scaffolds seeded with tenocytes. The scaffolds are preferably formed from biodegradable fibers formed of a polymer such as polyglycolic acid-polylactic acid copolymers, and seeded with cells isolated from autologous tendon or ligament by means of enzymatic digestion or direct seeding into tissue culture dishes from explants. The cell polymer constructs are then surgically transplanted to replace missing segments of functioning tendon or ligament.
