In this paper, at first we introduce a new index with the name CO-PI index and obtain some properties related to this new index. Then we compute this new index for TUC4C8 (S) nanotubes.
Vertex-PI index, Co-PI index, TUC4C8 (S) nanotube.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
