Publication number: 20100326834Abstract: This invention relates to the electrochemical deposition of carbon nanotubes (“CNTs”) on a substrate using an electrochemical cell. A dispersion of a complex of CNTs and an anionic polymer is neutralized and thereby caused to deposit on the anode plate of the cell.Type: ApplicationFiled: February 27, 2009Publication date: December 30, 2010Inventors: Gillian Althea Maria Reynolds, Ming Zheng

Publication number: 20100310658Abstract: The invention is directed to formation and use of electroprocessed fibrin as an extracellular matrix and, together with cells, its use in forming engineered tissue. The engineered tissue can include the synthetic manufacture of specific organs or tissues which may be implanted into a recipient. The electroprocessed fibrin may also be combined with other molecules in order to deliver the molecules to the site of application or implantation of the electroprocessed fibrin. The fibrin or fibrin/cell suspension is electrodeposited onto a substrite to form the tissues and organs.Type: ApplicationFiled: June 8, 2010Publication date: December 9, 2010Inventors: Gary L. Bowlin, Gary E. Wnek, David G. Simpson, Philippe Lam, Marcus E. Carr, JR.

Publication number: 20100310903Abstract: The present invention provides an alloy film of Mn or its Fe—Mn is depositable on a metalized alumina ceramic (Al2O3-SiO3) substrate for hermetically sealed glass-metal fusion used for aircraft switch assemblies. The coefficient of thermal expansion of Fe—Mn alloys appear to be fairly low, nearer to that of glass. Fe—Mn alloy film is an alternative to Fe64—Ni36 alloy films (Invar) normally used for glass to glass fusion purposes. Fe—Mn alloy films is also depositable directly on bare Alumina (Al2O3) substrate with or without zincating pretreatment. Similarly bright, smooth coherent film of Mn—Au or Fe—Mn—Ni Au alloys is depositable from an aqueous solution of simple salt bath or on Cu substrate without the use of cyanide without bridging with zincate processes.Type: ApplicationFiled: January 19, 2010Publication date: December 9, 2010Inventor: Bassey J. Udofot

Patent number: 7842177Abstract: A pigmented granular pigmented coating feedstock is prepared by melting a resin, which can be a solid resin based on polymerizable ethylenically unsaturated monomer or epoxy based resin, and a solid or viscous curing agent, blending the molten mass, and cooling to form a solid. The solid blend of resin and curing agent is ground to produce a granular feedstock. The feedstock is readily storable or shippable to a location for coating preparation. Alternatively a solid coating can be ground after shipping. An aqueous coating is made by dispersing the feedstock in water and mixing to form a dispersion. A salting agent and at least one additive can be added to form an aqueous coating composition. An article can be coated with the dispersion, for example, by electrodeposition.Type: GrantFiled: October 29, 2007Date of Patent: November 30, 2010Assignee: BASF Coatings GmbHInventor: Charles L.
