Spherical shapes minimize that energy, and as a result, toroidal droplets want to evolve to become spherical. We\u0026rsquo;re studying how that transition occurs.\u0026quot;...The impetus for the experimental work was inconsistencies between theoretical predictions and computer simulation of toroidal droplet transitions. What the researchers found tends to back up the simulation results. \u0026ldquo;However, the earlier theoretical work was essential in guiding the theory efforts and in illustrating what the problem was in order to correctly describe the experimental results,\u0026rdquo; says \u003Ca href=\u0022https:\/\/www.physics.gatech.edu\/user\/alberto-fernandez-nieves\u0022\u003EAlberto Fernandez-Nieves\u003C\/a\u003E, in whose lab the research took place. \u003Cem\u003EAlexandros Fragkopoulos is a graduate teaching assistant in the School of Physics, where Alberto Fernandez-Nieves is an associate professor.\u0026nbsp;\u003C\/em\u003E\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":"","uid":"34434","created_gmt":"2017-03-15 20:37:40","changed_gmt":"2017-03-16 18:05:23","author":"Renay San Miguel","boilerplate_text":"","field_publication":"","publication":"reconfigurable transceivers","field_article_url":"","publication_url":"http:\/\/www.futurity.org\/toroidal-droplets-1377982-2\/","dateline":{"date":"2017-03-13T00:00:00-04:00","iso_date":"2017-03-13T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"588827":{"id":"588827","type":"image","title":"Alexandros Fragkopoulos","body":null,"created":"1489611623","gmt_created":"2017-03-15 21:00:23","changed":"1489611623","gmt_changed":"2017-03-15 21:00:23","alt":"","file":{"fid":"224401","name":"Alexandros Fragkopoulos.jpg","image_path":"\/sites\/default\/files\/images\/Alexandros%20Fragkopoulos.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/Alexandros%20Fragkopoulos.jpg","mime":"image\/jpeg","size":60227,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/Alexandros%20Fragkopoulos.jpg?itok=UDoYC2fe"}},"588828":{"id":"588828","type":"image","title":"Alberto Fernandez-Nieves","body":null,"created":"1489611758","gmt_created":"2017-03-15 21:02:38","changed":"1489611758","gmt_changed":"2017-03-15 21:02:38","alt":"","file":{"fid":"224402","name":"Alberto Fernandez-Nieves.gif","image_path":"\/sites\/default\/files\/images\/Alberto%20Fernandez-Nieves.gif","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/Alberto%20Fernandez-Nieves.gif","mime":"image\/gif","size":141858,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/Alberto%20Fernandez-Nieves.gif?itok=Tj0-_IGi"}}},"media_ids":["588827","588828"],"groups":[{"id":"1278","name":"College of Sciences"},{"id":"126011","name":"School of Physics"}],"categories":[{"id":"8862","name":"Student Research"}],"keywords":[{"id":"4896","name":"College of Sciences"},{"id":"166937","name":"School of Physics"},{"id":"173769","name":"Alexandros Fragkopoulos"},{"id":"66681","name":"Alberto Fernandez-Nieves"},{"id":"173677","name":"toroidal droplets"},{"id":"173770","name":"spheres"},{"id":"5153","name":"Life Sciences"},{"id":"173768","name":"industrial processes"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
