C_<60> fullurene synthesis was carried out by using Ar, He and CO_2 induction thermal plasmas. Remarkable results are as follows.\n1) The transistor inverter supply was found to be useful to establish the inductively coupled plasma with a frequency of 450 kHz. At a power level of 30kW, several kinds of plasma can be generated in Ar, He and CO2 gas circumstance. The CO2 plasma was found to have relatively high temperature around 10,000 K compared to Ar and He plasma.\n2) These induction thermal plasmas were sufficiently stable for the injection of cold carbon powders up to a rate of 10 g/min, which is high enough quantity to produce the C_<60> cluster with a high rate.\n3) Among the experiments carried out under several conditions with respects to the gas sort, pressure and the power of plasma, Ar/He noble gas plasma showed the most highest C_<60> synthesis rate, while the dissociative CO_2 gas plasma showed no synthesis of C_<60>. The results indicate that a strong quenching effect of the radical C atom and C_2 molecule is essential for the synthesis of such high order fullurene materials.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:08555067, 研究期間(年度):1996 – 1998","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「低周波誘導熱プラズマ炉の試作と巨大クラスター生成への応用」課題番号08555067\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-08555067/085550671998kenkyu_seika_hokoku_gaiyo/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学工学部","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00066091","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=80135318"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=80135318","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-08555067/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-08555067/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-08555067/085550671998kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-08555067/085550671998kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"作田, 忠裕"}],"nameIdentifiers":[{"nameIdentifier":"11917","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"80135318","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=80135318"},{"nameIdentifier":"80135318","nameIdentifierScheme":"研究者番号","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000080135318"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-05-27"}],"displaytype":"detail","filename":"TE-PR-SAKUTA-T-kaken 1999-2p.pdf","filesize":[{"value":"111.2 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-SAKUTA-T-kaken 1999-2p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/59840/files/TE-PR-SAKUTA-T-kaken 1999-2p.pdf"},"version_id":"6b62260f-a55b-463a-892f-54893aa7e1d9"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"低周波誘導熱プラズマ炉の試作と巨大クラスター生成への応用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"低周波誘導熱プラズマ炉の試作と巨大クラスター生成への応用"},{"subitem_title":"Development of Low-Fregnency Induction Thermal Plasma for Cluster Synthesis","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2835"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-05-27"},"publish_date":"2022-05-27","publish_status":"0","recid":"59840","relation_version_is_last":true,"title":["低周波誘導熱プラズマ炉の試作と巨大クラスター生成への応用"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-07-01T06:34:28.111891+00:00"}
