For the methodology development, I fabricated an aerosol reaction flow cell, and it was coupled with micro-Raman spectroscope. Furthermore, a relative humidity control system to maintain the relative humidity in the flow cell was developed. The heterogeneous reaction experiments were performed as a function of particle composition, relative humidity, particle size, and particle acidity (=pH). As a result, the reaction rates are found to be significantly sensitive to relative humidity. They were then parameterized with relative humidity to obtain a simple equation representing a quantitative relation between the reaction rate and relative humidity. This parameterization was implemented in air pollution model to investigate the effect of relative humidity on NO2 reaction.","subitem_description_type":"Abstract"},{"subitem_description":"本研究では、単一粒子分光分析の開発、NO2のPM2.5への不均一反応速度を定量した。NO2の反応速度は、(1)微粒子の化学組成、(2)相対湿度、(3)粒子径、(4)微粒子の酸性度を反応条件として測定した。その結果、この反応速度は、相対湿度にもっとも強く依存することがわかり、反応速度と相対湿度の定量的な関係式を得ることができた。この関係式をもとに、新しく得られたNO2の反応速度の効果を大気化学モデルを用いて評価した。","subitem_description_type":"Abstract"},{"subitem_description":"本研究成果は、これまで見過ごされてきたNO2反応の重要性を見出した点である。これまでその重要性が見過ごされてきた最大の要因は、バルク溶液を用いた実験で得られた反応速度の結果を大気微粒子中の反応に直接適応してきたためであると考えられる。本研究成果と同様に、他の反応系でもバルク溶液中の反応とまったく異なる挙動を示す可能性があるため、エアロゾル反応速度の実験的検討がより重要になると考えられる。","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:20K23363, 研究期間(年度):2020-09-11 – 2022-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「単一粒子分光分析によるNO2ガスと大気中微粒子の不均一反応速度の定量化」課題番号20K23363\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-20K23363/20K23363seika/）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":"金沢大学理工研究域フロンティア工学系","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00059679","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/ja/search/?kw=50774535"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/search/?kw=50774535","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-20K23363"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-20K23363","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-20K23363/20K23363seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-20K23363/20K23363seika/","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":"玄, 大雄"}],"nameIdentifiers":[{"nameIdentifier":"94728","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"50774535","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=50774535"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-02-20"}],"displaytype":"detail","filename":"TE-PR-GEN-M-kaken 2022-5p.pdf","filesize":[{"value":"97.2 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-GEN-M-kaken 2022-5p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/53396/files/TE-PR-GEN-M-kaken 2022-5p.pdf"},"version_id":"0c304113-9f35-4216-9183-f259ae1f54f5"}]},"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":"単一粒子分光分析によるNO2ガスと大気中微粒子の不均一反応速度の定量化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"単一粒子分光分析によるNO2ガスと大気中微粒子の不均一反応速度の定量化"},{"subitem_title":"Measurements of heterogeneous reaction rates of NO2 and atmospheric aerosol particles using single particle analysis","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["4085"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-02-20"},"publish_date":"2023-02-20","publish_status":"0","recid":"53396","relation_version_is_last":true,"title":["単一粒子分光分析によるNO2ガスと大気中微粒子の不均一反応速度の定量化"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-07-01T05:15:40.196659+00:00"}
