The electronic and transport properties of fluorographane (CHF) nanoribbons, , bare (B-CHF) and hydrogen-passivated (H-CHF) CHF nanoribbons, are extensively investigated using first-principles calculations. The results indicate that edge states are present in all the B-CHF nanoribbons, which are not allowed in the H-CHF nanoribbons regardless of the directions. The spin splitting phenomenon of band structure only appears in the zigzag direction.

Hydrodynamic motion can generate a flux of electron-spin's angular momentum via the coupling between fluid rotation and electron spins. Such hydrodynamic generation, called spin hydrodynamic generation (SHDG), has recently attracted attention in a wide range of fields, especially in spintronics. Spintronics deals with spin-mediated interconversion taking place on a micro or nano scale because of the spin-diffusion length scale.

Ferromagnetic nanowires are likely to play an important role in future spintronic devices. Magnetic domain walls, which separate regions of opposing magnetization in a nanowire, can be manipulated and used to encode information for storage or to perform logic operations. Owing to their reduced size and dimensionality, the characterization of domain-wall motion is an important problem.
