Publication number: 20110189446Abstract: The invention provides a system and process of patterning structures on a carbon based surface comprising exposing part of the surface to an ion flux, such that material properties of the exposed surface are modified to provide a hard mask effect on the surface. A further step of etching unexposed parts of the surface forms the structures on the surface. The inventors have discovered that by controlling the ion exposure, alteration of the surface structure at the top surface provides a mask pattern, without substantially removing any material from the exposed surface. The mask allows for subsequent ion etching of unexposed areas of the surface leaving the exposed areas raised relative to the unexposed areas thus manufacturing patterns onto the surface. For example, a Ga+ focussed ion beam exposes a pattern onto a diamond surface which produces such a pattern after its exposure to a plasma etch.Type: ApplicationFiled: July 3, 2009Publication date: August 4, 2011Applicant: THE PROVOST, FELLOWS AND SCHOLARS OF THE COLLEGE O F THE HOLY AND UNDIVIDED TRINITY OF QUEEN ELIZABEInventors: Graham L.

The fugitive second thin film forming the precursor is selectively removed from between the first thin film and the third thin film using an etching medium introduced through the access sites, thereby forming the microchannel between the first thin film and the third thin film.Type: ApplicationFiled: July 1, 2010Publication date: February 17, 2011Inventors: Horacio D.

Publication number: 20110039184Abstract: A carbon nanosphere has at least one opening. The carbon nanosphere is obtained by preparing a carbon nanosphere and treating it with an acid to form the opening. The carbon nanosphere with at least one opening has higher utilization of a surface area and electrical conductivity and lower mass transfer resistance than a conventional carbon nanotube, thus allowing for higher current density and cell voltage with a smaller amount of metal catalyst per unit area of a fuel cell electrode.Type: ApplicationFiled: October 25, 2010Publication date: February 17, 2011Applicant: SAMSUNG SDI CO., LTD.Inventors: Hyuk CHANG, Chan-ho PAK, Jian Nong WANG

Patent number: 7879131Abstract: A process for encapsulating metal microparticles in a pH sensitive polymer matrix using a suspension containing the polymer. The process first disperses the metal particles in a polymeric solution consisting of a pH sensitive polymer. The particles are then encapsulated in the form of micro-spheres of about 5-10 microns in diameter comprising the pH sensitive polymer and the metal ions (Ni2+, Cu2+) to be coated. The encapsulated matrix includes first metal particles homogeneously dispersed in a pH sensitive matrix, comprising the second metal ions. A high shear homogenization process ensures homogenization of the aqueous mixture resulting in uniform particle encapsulation. The encapsulated powder may be formed using spray drying. The powder may be then coated in a controlled aqueous media using an electroless deposition process. The polymer is removed when the encapsulated micro-spheres encounter a pH change in the aqueous solution.Type: GrantFiled: August 15, 2007Date of Patent: February 1, 2011Assignee: Applied Nanotech Holdings, Inc.Inventors: Zvi Yaniv, Prabhu Soundarrajan
