Changes in the thermal structure of Na-kenyaite were investigated using the in situ high-temperature synchrotron X-ray diffraction data. Na-kenyaite was dehydrated at 200°C, and its crystal structure was maintained from 200 to 700°C despite its low crystallinity. It finally decomposed and crystallized to cristobalite via ¡-quartz. Na-kenyaite was ion-exchanged with Ag+ and Cu2+ ions in different ratios (Ag/Si = 0.01–0.077 and Cu/Si = 0.009–0.044), and the antibacterial properties of the ion-exchanged compounds were evaluated using gram-negative [Escherichia coli (E. coli)] and gram-positive [Staphylococcus aureus (S. aureus)] bacteria. Ion-exchanged compounds exhibited an increasing bactericidal effect when the ion-exchange ratios of the compounds increased owing to the release of metal ions with antibacterial properties from the host material. The antibacterial activity of the ion-exchanged compounds was compared based on the relative antibacterial activity, calculated using the inhibition zone obtained after two days of incubation. Cu-kenyaite exhibited better antibacterial activity than Ag-kenyaite against E. coli and S. aureus.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_30001_file22":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2025-01-06"}],"displaytype":"detail","filename":"JCS-Japan132_2_39.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://yamanashi.repo.nii.ac.jp/record/2000367/files/JCS-Japan132_2_39.pdf"},"version_id":"e9c857db-e367-4906-9d0c-2288e713e614"}]},"item_30001_language10":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_30001_publisher9":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Ceramic Society of Japan","subitem_publisher_language":"en"}]},"item_30001_relation14":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.2109/jcersj2.23140","subitem_relation_type_select":"DOI"}}]},"item_30001_resource_type11":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_30001_rights5":{"attribute_name":"権利情報","attribute_value_mlt":[{"subitem_rights":"Creative Commons Attribution 4.0 International (CC BY 4.0)","subitem_rights_language":"en","subitem_rights_resource":"https://creativecommons.org/licenses/by/4.0/"},{"subitem_rights":"©2024 The Ceramic Society of Japan","subitem_rights_language":"en"}]},"item_30001_source_identifier16":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"1882-0743","subitem_source_identifier_type":"PISSN"},{"subitem_source_identifier":"1348-6535","subitem_source_identifier_type":"EISSN"}]},"item_30001_subject7":{"attribute_name":"主題","attribute_value_mlt":[{"subitem_subject":"Hydrothermal reaction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Layered silicate","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ion-exchange","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Antibacterial property","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_30001_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Ion-exchange and antibacterial properties of layered silicate, Na-kenyaite, prepared using amorphous silicon dioxide (a-SiO2) blocks","subitem_title_language":"en"}]},"item_30001_version_type12":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_title":"Ion-exchange and antibacterial properties of layered silicate, Na-kenyaite, prepared using amorphous silicon dioxide (a-SiO2) blocks","item_type_id":"40035","owner":"86","path":["1736123338328"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-01-06"},"publish_date":"2025-01-06","publish_status":"0","recid":"2000367","relation_version_is_last":true,"title":["Ion-exchange and antibacterial properties of layered silicate, Na-kenyaite, prepared using amorphous silicon dioxide (a-SiO2) blocks"],"weko_creator_id":"86","weko_shared_id":-1},"updated":"2025-01-30T03:26:00.192268+00:00"}
