• investigation of the properties and applications of SWNTs. As it is well known that ILs are hygroscopic and that the amount of water absorbed in ILs can significantly affect the physical properties, such as polarity, viscosity, conductivity, and solubility [19][20][21], much research [21][22] have been carried

• local flow velocity. Unlike sensors based on hot-wire anemometry, these sensors were directional like lateral line neuromasts, i.e., along their dominant axis they responded to water flow in both directions with equal sensitivity but with opposite polarity. The detection limit for water flow was 100 μm

• HOPG (non-polar) to horizontally oriented tubules on polar substrates, e.g., silicon, alumina, or glass, they concluded that surface polarity is responsible for tubule orientation. They also demonstrated an increase in the hydrophobicity of the HOPG surface covered with tubules by measuring the contact

• we would also like to refer to the orientation of wax tubules found in previous studies of the self-assembly of natural nonacosan-10-ol wax on different substrates. Jetter and co-workers [2] showed that substrate polarity and roughness play no role in tubule crystallization by demonstrating a

• ] demonstrated the effect of substrate polarity on the tubule growth by showing a vertical orientation on HOPG and a horizontal orientation on silicon and alumina. However, in our study by combining various properties (e.g., polarity, crystallinity) together at two different surfaces we have demonstrated that
