Structural alteration of the amorphous carbonaceous grains was directly observed by in situ HRTEM observation. The specimen was heated to a maximum of 550℃. The HRTEM image of a prepared specimen showed the structure of the onion-like carbon. The onion-like structure distorted at 100℃, which suggested the evaporation of -OH groups included in the grains. Upon heating to 260℃, the centers of the onion-like grains formed holes of the order of 3 nm in size. On further heating to 550℃, the structure of the chained grains with a size of 10 nm changed to graphite sheets with a length of 50 nm by the surface melting coalescence among chained grains. The structural changes at the above temperatures have been observed only in amorphous carbonaceous grains produced in a methane gas atmosphere and have been attributed to the existence of hydrogen in the grains.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006036","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11182426","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Nanophysics in Frontier Project, Ritsumeikan University/Department of Electronics and Information Science, Kyoto Institute of Technology/Department of Nanophysics in Frontier Project, Ritsumeikan University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2003-03-01"}],"displaytype":"detail","filename":"KJ00000040872.pdf","filesize":[{"value":"6.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000040872","url":"https://nipr.repo.nii.ac.jp/record/6036/files/KJ00000040872.pdf"},"version_id":"b3c2b3ea-57cc-4b37-85e1-7d2c89d6ddff"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"amorphous carbonaceous grain, in situ observation, high resolution transmission electron microscope, methane gas, hydrogen","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Heating experiments of carbon grains: Implication for the origin of interstellar dust","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Heating experiments of carbon grains: Implication for the origin of interstellar dust"}]},"item_type_id":"1","owner":"4","path":["780"],"pubdate":{"attribute_name":"公開日","attribute_value":"2003-03-01"},"publish_date":"2003-03-01","publish_status":"0","recid":"6036","relation_version_is_last":true,"title":["Heating experiments of carbon grains: Implication for the origin of interstellar dust"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:07:07.758925+00:00"}
