含缺陷热驱动纳米管马达的质量输运
Mass transportation of thermally driven nanotube nanomotors with defects
摘要：
热驱动的纳米管纳米马达提供由温度梯度控制的线性质量输送。然而，在实验中的质量输运速度远低于模拟结果的潜在机制仍然不清楚。考虑到缺陷在制备的纳米管中是普遍存在的，我们使用分子动力学模拟来显示由缺陷引起的势垒或势阱将显著阻碍质量输运，这为理解微观水平上相对较低的值提供了可能的图片。讨论了最佳结构和影响性能的因素。结果表明，考虑缺陷对设计纳米管纳米马达和其他新型纳米马达器件具有指导意义。
英文摘要：
Thermally driven nanotube nanomotors provide linear mass transportation controlled by a temperature gradient. However, the underlying mechanism is still unclear where the mass transportation velocity in experiment is much lower than that resulting from simulations. Considering that defects are common in fabricated nanotubes, we use molecular dynamics simulations to show that the mass transportation would be considerably impeded by the potential barriers or wells induced by the defects, which provides a possible picture to understand the relative low value at microscopic level. The optimal structure and the factors which would affect the performance are discussed. The result indicates considering defects is helpful in designing nanotube nanomotor and other new nanomotor-based devices.
