This apparatus is composed of two upper and lower round metal-blocks which are held together with a center pin. A sharp boundary between solution and solvent can be formed by rotating the upper section which contains solvent relative to the lower section which contains solution. This apparatus is suitable for diffusion measurements on colored substances, turbid solutions, and very dilute solutions, the diffusion constants of which can hardly be measured by the usual optical method. The substances tried were methylene blue (D_<20,w> = 45 × 10^<-7>cm^2/sec at 0.05% and 0.025%), ribonucleic acid from brewers yeast (D_<20,w> = 8.7 × 10^<-7>cm^2/sec at 0.1% and 0.05%), and deoxyribonucleic acid from herring soft roe (D_<20,w> = 1.6, 1.7, and 1.9 × 10^<-7>cm^2/sec at 0.28%, 0.1%, and 0.03% respectively). The data obtained on nucleic acids were quite in agreement with those obtained by the optical method. It must be noteworthy that diffusion constant of substances which have any activity such as bacteriophages, enzymes, or radio-isotope-labeled compounds can be measured without any special considerations on contaminating substances even in very dilute solutions.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA1511813000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学理工学研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0371-6090","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162611","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学理工学研究所"},{"subitem_text_value":"東京大学理工学研究所"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"THE INSTITUTE OF SCIENCE AND TECHNOLOGY UNIVERSITY OF TOKYO"},{"subitem_text_language":"en","subitem_text_value":"THE INSTITUTE OF SCIENCE AND TECHNOLOGY UNIVERSITY OF TOKYO"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中村, 正好"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"渡辺, 格"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAKAMURA, Masayoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"WATANABE, Itaru","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA1511813.pdf","filesize":[{"value":"503.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA1511813.pdf","url":"https://jaxa.repo.nii.ac.jp/record/34351/files/SA1511813.pdf"},"version_id":"73829480-0cf0-4ae3-aa46-f1006981e022"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"分析による拡散定数の新しい測定装置について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"分析による拡散定数の新しい測定装置について"}]},"item_type_id":"9","owner":"1","path":["1890","1908"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"34351","relation_version_is_last":true,"title":["分析による拡散定数の新しい測定装置について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:43:49.684707+00:00"}
