The shell thickness of the hollow TiO_2 nanoparticles (20-280 nm) was controlled by adjusting the heating rate (2.0-10.0 °C/min). The preparation of different spherical porous metal oxide nanoparticles, including CeO_2, SiO_2, TiO_2, ZrO_2, and ZnO, demonstrated the versatility of the synthetic approach. In addition, several rare earth-doped spherical mesoporous metal oxide nanoparticles, including CeO_2:Er, CeO_2:Er,Yb, ZrO_2:Er, and TiO_2:Er, which exhibit energy upconversion emission, were successfully prepared using this one-pot, single-step, supercritical methanol method. The obtained spherical mesoporous CeO_2:Er and CeO_2:Er,Yb nanoparticles emit green light upon excitation, even when irradiated with a low-power IR laser (980 nm, 10 mW) without calcination. Several other (metal) elements were also easily doped into spherical, mesoporous TiO_2 nanoparticles, such as Eu, Ce, Yb, Fe, and N, using a similar procedure. Furthermore, the spherical mesoporous TiO_2 nanoparticles were successfully applied as a new material for the transport of DNA via biolistic bombardment.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"De Gruyter"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1515/pac-2013-1117","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利（URI）","attribute_value_mlt":[{"subitem_rights":"http://dx.doi.org/10.1515/pac-2013-1117 | http://dx.doi.org/10.1515/pac-2013-1117"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0033-4545","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_18":{"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":"Wang, Pengyu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kobiro, Kazuya"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-02-13"}],"displaytype":"detail","filename":"28-38.pdf","filesize":[{"value":"5.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"28-38.pdf","url":"https://kutarr.kochi-tech.ac.jp/record/290/files/28-38.pdf"},"version_id":"7ea90cbd-2cb3-45b7-9d64-dd5a71cdb5bc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"mesoporous nanoparticles","subitem_subject_scheme":"Other"},{"subitem_subject":"NMS-IX","subitem_subject_scheme":"Other"},{"subitem_subject":"one-pot single-step synthesis","subitem_subject_scheme":"Other"},{"subitem_subject":"supercritical alcohols","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Synthetic versatility of nanoparticles: A new, rapid, one-pot, single-step synthetic approach to spherical mesoporous (metal) oxide nanoparticles using supercritical alcohols","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Synthetic versatility of nanoparticles: A new, rapid, one-pot, single-step synthetic approach to spherical mesoporous (metal) oxide nanoparticles using supercritical alcohols"}]},"item_type_id":"2","owner":"2","path":["5"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-03-24"},"publish_date":"2017-03-24","publish_status":"0","recid":"290","relation_version_is_last":true,"title":["Synthetic versatility of nanoparticles: A new, rapid, one-pot, single-step synthetic approach to spherical mesoporous (metal) oxide nanoparticles using supercritical alcohols"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-15T13:39:13.769708+00:00"}
