据报道,美国科学家研制成了世界上第一辆“纳米车辆”。科学家说,未来这种车辆可用来运输单个的分子,成为“纳米生产”中的有用工具。莱斯大学教授詹姆斯·托尔等人耗费8年时间制作的这种“纳米车辆”不过3～4纳米见方,不到头发丝直径的2万分之一,却拥有完整的底盘、轮轴和车轮 According to reports, American scientists have developed the world’s first “nano vehicle.” Scientists say that in the future such vehicles can be used to transport individual molecules and become a useful tool in “nano-production.” The “nano-vehicle” that Rice University Professor James Tolle and others spent 8 years producing is only 3 to 4 nanometers square, less than 20,000 of the diameter of a hair filament, but it has a complete chassis, axles and wheels.
