That is to measure the deformation of surfactant micelles when aqueous solutions of surfactant is flowing. But micelles are too small to see, so I used some oil-in-water type (O/W) and water-in-oil type (W/O) emulsions made of oleic acid and pure water (these are as a bigger model of surfactant micelles). The ratio of height to width was calculated using by the observation system of heating, shear flowing.\n\nThe following results are obtained. The ratio of height to width was increased (>1), it means the shape of drops deformed to elliptic sphere, when every emulsions were flowing. And the flow stopped, it was decreased immediately (almost=1), the shape returned to sphere. For all emulsions used, the ratio of height to width increases with an increase in low shear rate. But the ratio decreases at some high shear rate, and it increases again with higher shear rate. There is room for further investigation on this point.","subitem_description_type":"Other"}]},"item_28_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"AMAKI, Keiko"}]}]},"item_28_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学教育学部"}]},"item_28_version_type_27":{"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":"天木, 桂子"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"kaken13680110.pdf","filesize":[{"value":"4.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kaken13680110.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/10446/files/kaken13680110.pdf"},"version_id":"0251fe23-cf20-4200-b3a5-69bb980a0e17"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Analysis of Pictures","subitem_subject_scheme":"Other"},{"subitem_subject":"Aqueous Solution of Surfactant","subitem_subject_scheme":"Other"},{"subitem_subject":"Emulsion","subitem_subject_scheme":"Other"},{"subitem_subject":"Fluid Force","subitem_subject_scheme":"Other"},{"subitem_subject":"Washing","subitem_subject_scheme":"Other"},{"subitem_subject":"エマルション","subitem_subject_scheme":"Other"},{"subitem_subject":"ミセル","subitem_subject_scheme":"Other"},{"subitem_subject":"効力","subitem_subject_scheme":"Other"},{"subitem_subject":"洗浄","subitem_subject_scheme":"Other"},{"subitem_subject":"流体力","subitem_subject_scheme":"Other"},{"subitem_subject":"画像解析","subitem_subject_scheme":"Other"},{"subitem_subject":"界面活性剤水溶液","subitem_subject_scheme":"Other"}]},"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":"洗浄機構に関する流体力の検討－界面活性剤水溶液の粘弾性挙動の解明と汚れ除去機構との関連－","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"洗浄機構に関する流体力の検討－界面活性剤水溶液の粘弾性挙動の解明と汚れ除去機構との関連－"}]},"item_type_id":"28","owner":"3","path":["1524"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-11-01"},"publish_date":"2011-11-01","publish_status":"0","recid":"10446","relation_version_is_last":true,"title":["洗浄機構に関する流体力の検討－界面活性剤水溶液の粘弾性挙動の解明と汚れ除去機構との関連－"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:34:32.110269+00:00"}
