| 20110031104 | CARBON ION BEAM GROWTH OF ISOTOPICALLY-ENRICHED GRAPHENE AND ISOTOPE-JUNCTIONS - Isotopically-enriched graphene and isotope junctions are epitaxially grown on a catalyst substrate using a focused carbon ion beam technique. The focused carbon ion beam is filtered to pass substantially a single ion species including a single desired carbon isotope. The ion beam and filtering together provide a means to selectively isotopically-enrich the epitaxially-grown graphene from given carbon precursor and to selectively deposit graphene enriched with different carbon isotopes in different regions. | 02-10-2011 |

| 20080271986 | Method for Isotope Separation of Ytterbium - A method for isotope separation of ytterbium comprises isotope-selective photoionizing of a target isotope by use of a laser, and photoionizing of the target isotope from a metastable state to a continuum state or an auto-ionization state through excited states. The photoionized isotope ions of ytterbium can be separated within an electric field. With the method, it is possible to separate a great amount of ytterbium isotope by use of a simple apparatus while ensuring a highly economic efficiency in comparison with a conventional EM method. | 11-06-2008 |
