All you need is a pipette and a hotplate.<\/strong><\/p>\r\n<p>Two-dimensional nanosheets have been generating a lot of excitement worldwide recently. Their broad range of unique electronic, magnetic, optical and thermal properties that could find their way into next-generation devices. However, further development of 2D materials depends on finding deposition processes that enable precise layer-by-layer control of thin-films while reducing time, cost and energy\/sample consumption.<\/p>\r\n<p>Prof. Minoru Osada and his collaborators found that a simple one-drop approach improves \u201cdrop casting\u201d fabrication of tiled nanosheets. Drop casting is one of the most versatile and cost-effective methods of depositing nanomaterials on solid surfaces. But it has serious drawbacks, including the so-called coffee-ring effect, a pattern left by particles after the liquid evaporates.\u00a0<\/p>\r\n<p>They found, to their surprise, that controlled convection by a pipette and a hotplate causes uniform deposition rather than the ring-like pattern, suggesting a new possibility for drop casting. The process is surprisingly simple -- dropping a solution containing 2D nanosheets with a simple pipette onto a substrate heated on a hotplate, followed by removal of the solution, causes the nanosheets to come together in about 30 seconds to form a tile-like layer.<br>They also produced various functional coatings such as conducting, semiconducting, insulating, magnetic and photochromic coatings in multilayer, superlattice and submicrometer-thick forms, which showed the potential for a convenient way to produce high-quality 2D nanosheet films. If the process can be scaled up, it could advance development of next-generation electronics.<\/p>\r\n<p><span>\u00a0<\/span><\/p>\r\n<p><a href=\"https:\/\/www.imass.nagoya-u.ac.jp\/press_release\/368.html\/attachment\/201104-press_m-osada_s\/\" rel=\"attachment wp-att-2663\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.imass.nagoya-u.ac.jp\/wp\/wp-content\/uploads\/2020\/11\/201104-press_m-osada_s-1024x852.png\" alt=\"\" width=\"800\" height=\"666\" class=\"aligncenter wp-image-2663\" srcset=\"https:\/\/www.imass.nagoya-u.ac.jp\/wp\/wp-content\/uploads\/2020\/11\/201104-press_m-osada_s-1024x852.png 1024w, https:\/\/www.imass.nagoya-u.ac.jp\/wp\/wp-content\/uploads\/2020\/11\/201104-press_m-osada_s-300x250.png 300w, https:\/\/www.imass.nagoya-u.ac.jp\/wp\/wp-content\/uploads\/2020\/11\/201104-press_m-osada_s-768x639.png 768w, https:\/\/www.imass.nagoya-u.ac.jp\/wp\/wp-content\/uploads\/2020\/11\/201104-press_m-osada_s.png 1200w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/a><\/p>\r\n<p><strong>Reference<\/strong><\/p>\r\n<p>\u201cSingle Droplet Assembly for Two-Dimensional Nanosheet Tiling\u201d<br>Yue Shi, Minoru Osada*, Yasuo Ebina and Takayoshi Sasaki<\/p>\r\n<p>ACS Nano 14, 15216\u201315226 (2020). <br>DOI :\u00a0<span><a href=\"https:\/\/doi.org\/10.1021\/acsnano.0c05434\">10.1021\/acsnano.0c05434<\/a><\/span><\/p>\r\n<p><span>\u00a0<\/span><\/p>\r\n<p><strong>Contact<\/strong><\/p>\r\n<p>Professor Minoru Osada<br>Institute of Materials and Systems for Sustainability (IMaSS), Nagoya University<br>E-mail. mosada[at]imass.nagoya-u.ac.jp<\/p>","protected":false},"excerpt":{"rendered":"<p>A research team at IMaSS has developed a surprisingly simple method for fabricating highly organized mono- and [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":2663,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[2],"tags":[],"class_list":["post-368","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-research"],"acf":[],"aioseo_notices":[],"publishpress_future_action":{"enabled":false,"date":"2026-05-08 07:47:53","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category","extraData":[]},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/www.imass.nagoya-u.ac.jp\/en\/wp-json\/wp\/v2\/posts\/368","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.imass.nagoya-u.ac.jp\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.imass.nagoya-u.ac.jp\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.imass.nagoya-u.ac.jp\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.imass.nagoya-u.ac.jp\/en\/wp-json\/wp\/v2\/comments?post=368"}],"version-history":[{"count":9,"href":"https:\/\/www.imass.nagoya-u.ac.jp\/en\/wp-json\/wp\/v2\/posts\/368\/revisions"}],"predecessor-version":[{"id":2666,"href":"https:\/\/www.imass.nagoya-u.ac.jp\/en\/wp-json\/wp\/v2\/posts\/368\/revisions\/2666"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.imass.nagoya-u.ac.jp\/en\/wp-json\/wp\/v2\/media\/2663"}],"wp:attachment":[{"href":"https:\/\/www.imass.nagoya-u.ac.jp\/en\/wp-json\/wp\/v2\/media?parent=368"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.imass.nagoya-u.ac.jp\/en\/wp-json\/wp\/v2\/categories?post=368"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.imass.nagoya-u.ac.jp\/en\/wp-json\/wp\/v2\/tags?post=368"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
