利用分子动力学模拟，我们演示了在旋转电场和旋转磁场的组合作用下，水通过碳纳米管的泵送。驱动力是电荷在磁场中运动产生的洛伦兹力，运动是由电场的旋转引起的。我们发现，平均抽水速度v与磁场强度B之间存在线性关系，可以用来控制连续单向水流的流量。这种方法有望用于无压力梯度的液体循环。
Using molecular dynamics simulations, we demonstrate pumping of water through a carbon nanotube by applying the combination of a rotating electric field and a rotating magnetic field. The driving force is a Lorentz force generated from the motion of charges in the magnetic field, and the motion is caused by the rotation of the electric field. We find that there exits a linear relationship between the average pumping velocity v and magnetic field strength B, which can be used to control the flux of the continuous unidirectional water flow. This approach is expected to be used in liquid circulation without a pressure gradient.
