MC is a supra-molecule system impregnated with a huge amount of water about 99% by weight. In the previous literature, we elucidated that 90% of total water is accumulated in non-crystalline bundle causing concentration fluctuations. In this paper, we develop our arguments by newly adding the knowledges on (i) the hierarchy in a bacterium body studied by SANS & USANS and (ii) the non-crystalline local structure in as-produced MC in a culture solution, confirmed by neutron diffraction with polarization analyses. As a control to emphasize the peculiarity of MC, we compare MC to a synthetic polymer gel of poly(N-isopropylacrylamide) (PNIPAAm) in a swollen state. Consequently, we conclude that a mechanism of excellent water absorption found for MC is attributed to capillarity related to hierarchically preserved non-crystalline domains, whereas tight hydration on to a monomer unit via a hydrogen bond is crucial to result in high water absorption for the PNIPAAm gel.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.polymer.2019.05.022","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.polymer.2019.05.022","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0032-3861","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Koizumi, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"760720","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ザオ, ユエ"}],"nameIdentifiers":[{"nameIdentifier":"760721","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ananda, Putra"}],"nameIdentifiers":[{"nameIdentifier":"760722","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhao, Yue","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"760723","nameIdentifierScheme":"WEKO"}]}]},"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":"Hierarchical structure of microbial cellulose and marvelous water uptake, investigated by combining neutron scattering instruments at research reactor JRR-3, Tokai","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Hierarchical structure of microbial cellulose and marvelous water uptake, investigated by combining neutron scattering instruments at research reactor JRR-3, Tokai"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-05-14"},"publish_date":"2019-05-14","publish_status":"0","recid":"75936","relation_version_is_last":true,"title":["Hierarchical structure of microbial cellulose and marvelous water uptake, investigated by combining neutron scattering instruments at research reactor JRR-3, Tokai"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:43:45.181680+00:00"}
