The hydrogen dissolution process has been studied and it is discussed here. The values of hydrogen solubility vary substantially among the samples up to about a factor of 16. A strong correlation has been observed between the values of hydrogen solubility and the degrees of graphitization determined by X-ray diffraction technique. The relation can be extended even for the neutron irradiated samples. Hydrogen dissolution into graphite can be explained with the trapping of hydrogen at defect sites (e.g. dangling carbon bonds) considering an equilibrium reaction between hydrogen molecules and the trapping sites. The migration of hydrogen in graphite is speculated to result from a sequence of detrapping and retrapping events with high energy activation processes.","subitem_description_type":"Abstract"}]},"item_4_description_41":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"紀要類(bulletin)","subitem_description_type":"Other"}]},"item_4_description_66":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"521589 bytes","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.50974/00043592","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Tohoku University"}]},"item_4_radio_69":{"attribute_name":"公開範囲","attribute_value_mlt":[{"subitem_radio_item":"学外"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408808","subitem_source_identifier_type":"ISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00836167","subitem_source_identifier_type":"NCID"}]},"item_4_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Atsumi, Hisao"}],"nameIdentifiers":[{"nameIdentifier":"110708","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iseki, Michio"}],"nameIdentifiers":[{"nameIdentifier":"110709","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shikama, Tatsuo"}],"nameIdentifiers":[{"nameIdentifier":"110710","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-16"}],"displaytype":"detail","filename":"KJ00004200581.pdf","filesize":[{"value":"521.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004200581.pdf","url":"https://tohoku.repo.nii.ac.jp/record/47029/files/KJ00004200581.pdf"},"version_id":"c39fb8e4-ca5f-4678-b479-64bf9634af23"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"graphite","subitem_subject_scheme":"Other"},{"subitem_subject":"hydrogen retention","subitem_subject_scheme":"Other"},{"subitem_subject":"reactor irradiation","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":"Trapping and detrapping of hydrogen in graphite materials exposed to hydrogen gas","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Trapping and detrapping of hydrogen in graphite materials exposed to hydrogen gas"}]},"item_type_id":"4","owner":"3","path":["267"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-05-02"},"publish_date":"2008-05-02","publish_status":"0","recid":"47029","relation_version_is_last":true,"title":["Trapping and detrapping of hydrogen in graphite materials exposed to hydrogen gas"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T14:56:18.007733+00:00"}
