The motion of solid state nanomotors, , molybdenum carbide nanoparticles, which were driven carbon-decomposition catalytic reactions at ∼2900 K, was directly observed by transmission electron microscopy. The nanomotors exhibited unidirectional linear motions inside the hollow space of multiwall carbon nanotubes, reciprocating motions around the nanotube endcaps, and rotational motions in the hollow spaces of carbon nanocapsules. The inner atomic wall-layers of carbon nanotubes and nanocapsules were consumed during the nanomotor motions.
通过透射电子显微镜直接观察到了固态纳米马达（碳化钼纳米颗粒）的运动，这些纳米颗粒在约2900 K的温度下驱动碳分解催化反应。纳米马达在多壁碳纳米管的中空空间内呈现单向直线运动，围绕纳米管端帽做往复运动，并在碳纳米胶囊的中空空间内做旋转运动。在纳米马达运动过程中，碳纳米管和碳纳米胶囊的内部原子壁层被消耗。
