Abstract Rehybridization of electronic orbitals in carbon nanotubes contains tilting angles of $\pi $ orbital, electrons wavefunctions of $\pi $ orbital and $\sigma $ orbital, degrees of hybridization, etc. In this paper, we have obtained analytical formulas of tilting angle of $\pi $ orbital relative to tube surface, electrons wavefunctions of $\pi $ orbital and $\sigma $ orbital, degrees of hybridization, separately, as well as the numerical results.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
