However, the relationship between the self-propulsion and the convection, and the self-propulsion control has not been fully clarified.<\/p>\n<p>This study focuses on the convection generated around and inside a 1-pentanol droplet dropped into the hole of the exoskeleton, which floats in the aqueous solution. We observe the self-propulsion behavior of the droplet, and the convection generated around and inside the droplet from the two directions. Based on these experimental results, we analyze the convection generated three-dimensionally to understand the dominant factor determining the self-propulsion direction.<\/p>\n<div style=\"width: 676px;\" class=\"wp-video\"><!--[if lt IE 9]><script>document.createElement('video');<\/script><![endif]-->\n<video class=\"wp-video-shortcode\" id=\"video-757-1\" width=\"676\" height=\"380\" preload=\"metadata\" controls=\"controls\"><source type=\"video\/mp4\" src=\"https:\/\/www.sawada.phys.waseda.ac.jp\/wp-content\/uploads\/video1.mp4?_=1\" \/><a href=\"https:\/\/www.sawada.phys.waseda.ac.jp\/wp-content\/uploads\/video1.mp4\">https:\/\/www.sawada.phys.waseda.ac.jp\/wp-content\/uploads\/video1.mp4<\/a><\/video><\/div>\n<p>\u5916\u9aa8\u683c\u306b\u3088\u3063\u3066\u5f62\u72b6\u3092\u56fa\u5b9a\u3057\u305f\u6db2\u6ef4\u306e\u81ea\u8d70\u306e\u6319\u52d5<\/p>\n<div style=\"width: 676px;\" class=\"wp-video\"><video class=\"wp-video-shortcode\" id=\"video-757-2\" width=\"676\" height=\"541\" preload=\"metadata\" controls=\"controls\"><source type=\"video\/mp4\" src=\"https:\/\/www.sawada.phys.waseda.ac.jp\/wp-content\/uploads\/video2.mp4?_=2\" \/><a href=\"https:\/\/www.sawada.phys.waseda.ac.jp\/wp-content\/uploads\/video2.mp4\">https:\/\/www.sawada.phys.waseda.ac.jp\/wp-content\/uploads\/video2.mp4<\/a><\/video><\/div>\n<div style=\"width: 676px;\" class=\"wp-video\"><video class=\"wp-video-shortcode\" id=\"video-757-3\" width=\"676\" height=\"541\" preload=\"metadata\" controls=\"controls\"><source type=\"video\/mp4\" src=\"https:\/\/www.sawada.phys.waseda.ac.jp\/wp-content\/uploads\/video3.mp4?_=3\" \/><a href=\"https:\/\/www.sawada.phys.waseda.ac.jp\/wp-content\/uploads\/video3.mp4\">https:\/\/www.sawada.phys.waseda.ac.jp\/wp-content\/uploads\/video3.mp4<\/a><\/video><\/div>\n<p>\u6db2\u6ef4\u306e\u5468\u8fba\u304a\u3088\u3073\u5185\u90e8\u306b\u767a\u751f\u3059\u308b\u5bfe\u6d41<\/p>\n<p>&nbsp;<\/p>\n<p>\u203b\u6c34\u6eb6\u6db2\u6fc3\u5ea6\uff1a0.5 mL \/ 100 mL water<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>1-\u30da\u30f3\u30bf\u30ce\u30fc\u30eb\u6db2\u6ef4\u306e\u81ea\u8d70\u73fe\u8c61\u306b\u304a\u3044\u3066\u767a\u751f\u3059\u308b\u5bfe\u6d41\u3068\u81ea\u8d70\u7279\u6027\u306e\u95a2\u4fc2\u306e\u8003\u5bdf &#038;nb&#8230; <a class=\"more-link\" href=\"https:\/\/www.sawada.phys.waseda.ac.jp\/?page_id=757\">Continue Reading &rarr;<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"_links":{"self":[{"href":"https:\/\/www.sawada.phys.waseda.ac.jp\/index.php?rest_route=\/wp\/v2\/pages\/757"}],"collection":[{"href":"https:\/\/www.sawada.phys.waseda.ac.jp\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.sawada.phys.waseda.ac.jp\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.sawada.phys.waseda.ac.jp\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.sawada.phys.waseda.ac.jp\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=757"}],"version-history":[{"count":4,"href":"https:\/\/www.sawada.phys.waseda.ac.jp\/index.php?rest_route=\/wp\/v2\/pages\/757\/revisions"}],"predecessor-version":[{"id":1293,"href":"https:\/\/www.sawada.phys.waseda.ac.jp\/index.php?rest_route=\/wp\/v2\/pages\/757\/revisions\/1293"}],"wp:attachment":[{"href":"https:\/\/www.sawada.phys.waseda.ac.jp\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=757"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
