碳纳米管——那些准备彻底变革材料科学和电子学领域的微小碳圆柱体——变得更小了。 根据发表在11月2日出版的《自然》杂志上的两份报告,科学家们发现了已知最小的稳定碳纳米管。 由日本筑波NEC公司的秦鲁昌和香港科技大学的唐子晋领导的团队观察到了这些微小的管子,它们的宽度为0.4纳米,代表了理论上的最小尺寸极限。 碳纳米管比DNA链还小,最早在1990年代初期被描述。 从那时起,它们就引起了世界各地科学家的关注,他们设想使用碳纳米管来制造更好的电视、电池、无线通信系统,以及增强材料强度等等。 除了重量轻强度高之外,这些普通石墨的微小变体还具有良好的导热性和有趣的电子特性。 尽管如此,研究人员才刚刚开始了解和利用纳米管,因此它们究竟有多大用处还有待观察。

Kate Wong is an award-winning science writer and senior editor at 大众科学 focused on evolution, ecology, anthropology, archaeology, paleontology and animal behavior. She is fascinated by human origins, which she has covered for more than 25 years. Recently she has become obsessed with birds. Her reporting has taken her to caves in France and Croatia that Neandertals once called home, to the shores of Kenya's Lake Turkana in search of the oldest stone tools in the world, to Madagascar on an expedition to unearth ancient mammals and dinosaurs, to the icy waters of Antarctica, where humpback whales feast on krill, and on a "Big Day" race around the state of Connecticut to find as many bird species as possible in 24 hours. Kate is co-author, with Donald Johanson, of Lucy's Legacy: The Quest for Human Origins. She holds a bachelor of science degree in biological anthropology and zoology from the University of Michigan.
