而后当研究人员用一张膜过滤溶液时，表面活性剂被排出，化合物们立马自发重组为一个活力焕发的成形光电管。
Then, when the researchers removed the surfactant by pushing the solution through a membrane, the compounds spontaneously assembled once again into a perfectly formed, rejuvenated photocell.
由于有机发光二极管本身能通过电流使有机化合物发光，不需要背光照明，因此可以做得比液晶显示器更轻、更薄，更有柔韧性。
Because OLEDs do not need to be backlit-they get their lighting from organic compounds that emit light in response to electric current-they can be thinner, lighter and more flexible than LCDs.
杜克团队向我们演示了颗粒的核心提供了这些化合物，然后这些化合物就黏在了像刷子一样的纤毛上面，而这些纤毛是我们的呼吸道管里用来清除黏液用的。
The Duke team showed that the particle core delivers these organic chemicals onto brush-like surfaces called cilia, which clear mucus from the airway lining.
