Slippery bottle solves a sticky problem 科學家研發(fā)不粘涂層防止粘稠液體掛瓶

Women prepare for South Pole trek 英國女性探險隊即將踏上遠涉南極之旅

文字稿

It's something we've all struggled with – how to get that last drop of ketchup out of the bottle. Here at MIT they've developed this clever new technology. The container has been specially engineered to enable the ketchup or any other sticky liquid to slip out easily. Scientists coat the inside with a rough surface. They then put a thin layer over it and they cover that with a liquid which fills in the troughs and forms a very slippery surface. This coating process could cut huge amounts of waste.

我們每個人都遇到過這樣的難題：怎么才能擠出瓶子里剩下的最后一小團番茄醬？麻省理工學院（MIT）的一組研究人員開發(fā)出了一種巧妙的新技術。該容器已經(jīng)過特殊的設計改造，能夠讓番茄醬等任何粘稠的液體輕而易舉地從瓶子里流出來?？茖W家們在瓶壁的內側涂抹一層粗糙的表面，并在上方覆蓋一層輕薄的物質，然后鋪上一種能夠注滿溝槽并形成非常順滑表面的液體。這個涂層的過程能大量減少浪費的情況。
