“…For example, high-speed water transfer was observed in the nanochannels made from such materials as slim carbon nanotubes (CNTs), pumice, and ion channels in biofilms [ 29 , 30 , 31 ]. In this study, we adopt CNTs to build a new type of nanochannel for water purification owing to CNTs’ excellent mechanical properties, thermal and chemical stabilities, and extremely low friction during relative motion [ 32 , 33 , 34 ] or mass transfer [ 19 ]. For example, the ratio of desalination of the CNTs is higher than 95% when their diameters are between 1.0 and 1.1 nm [ 35 ].…”

We propose a CNT-based concentric twin tube (CTT) as nanochannels for both water purification and ion separation at the nanoscale. In the model, a source reservoir dealing with the solution connects three containers via the CTT that has three subchannels for mass transfer. Before entering the three subchannels, the solution in the separating zone will form three layers (the aqua cations, water, and the aqua anions, respectively) by applying a charged capacitor with the two electrodes parallel to the flow direction of the solution. Under an electric field with moderate intensity, the three subchannels in the CTT have stable configurations for mass transfer. Since the water and the two types of aqua ions are collected by three different containers, the present model can realize both ion separation and water purification. The mass transfer in the subchannels will be sped up by an external pressure exerted on the solution in the source reservoir. The physical properties of the model, e.g., water purification speed, are analyzed with respect to the effects of the electric field, the size of CTT, and the concentration of solute, such as NaCl.

“…The IRD atoms will repel the nanotubes in their thermal vibration-induced collisions and can drive the nanotubes to rotate when the non-zero moment around the axis of rotational symmetry of the ring is induced by the repulsion due to the IRD and the friction with the stator. [22][23][24][25] It is undeniable that the driving methods of nanomotors described above have their unique characteristics and perform well in some specific tasks. In order to accelerate the development of micro/nanomotor technology, manipulation accuracy should be the focus.…”
