Publication number: 20120009504Abstract: A method comprises creating an electrode by depositing alternating first and second layers on a substrate, and using the electrode to make a solid oxide fuel cell. The first layer comprises a metal, and the second layer comprises a non-metal, for example a ceramic material. The substrate may be moved between a first region containing the metal and substantially free of the non-metal, and a second region containing the non-metal and substantially free of the metal. The composition of the metal and/or the non-metal may be varied along the thickness of the layers. The deposited layers may be heated. A fuel cell may have a fuel cell electrode that comprises a substrate, and alternating first and second layers deposited on the substrate, where the first layer includes a metal and the second layer includes a non-metal. The fuel cell may be a solid oxide fuel cell.Type: ApplicationFiled: January 20, 2010Publication date: January 12, 2012Applicant: PRESIDENT AND FELLOWS OF HARVARD COLLEGEInventors: Shriram Ramanathan, Alexander C.

Patent number: 5304111Abstract: A flexible planar magnetic sheet for therapeutic use has a regular repeating pattern of curved first and second areas of alternating magnetic polarity arranged so that a line traverses a plurality of said curved areas in a majority of possible orientations of the line along the surface plane of the sheet with respect to the pattern. In one embodiment, the pattern comprises an array of polka dot regions of one polarity uniformly sized and spaced on a background of opposite polarity. Alternatively, the pattern can be shaped as a series of interdigitated undulating first and second areas of alternating magnetic polarity. The areas each have curved boundaries defined by wavy lines and a width which varies between a maximum and a minimum proceeding generally lengthwise along the wavy lines of a lengthwise periodicity to define lobe-shaped portions of each area.Type: GrantFiled: June 19, 1992Date of Patent: April 19, 1994Assignee: Nikken, Inc.Inventors: Hiroyuki Mitsuno, Alexander C.
