飞机、汽车和电池的能效在很大程度上都取决于其制造材料的重量。纳米结构的陶瓷可以用来建造更轻更牢固的飞机与电池。这种由像微型埃菲尔铁塔的支杆一样纵横交错的纳米级支杆组成的新型材料,是有史以来最牢固最轻质的物质之一。如果研究人员能够想出如何大批量生产这一物质,就可以将它做为制造飞机、卡车和电池电极的结构材料。由加州理工学院材料科学家茱莉亚·格里尔(Julia Greer)带领的研究人员发现,通过用心设计纳米级支杆和
The energy efficiency of aircraft, cars and batteries depends to a large extent on the weight of the materials they are made of. Nanostructured ceramics can be used to build lighter and stronger aircraft and batteries. This new material, made of nanoscale struts, like the tiny Eiffel Tower struts, is one of the firmest and lightest ever. If researchers can figure out how to mass-produce this substance, they can use it as a structural material in the manufacture of aircraft, truck and battery electrodes. Researchers led by material scientist Julia Greer at the California Institute of Technology found that by carefully designing nanoscale struts and
