GENERAL FORMULA FOR DEGREE-BASED TOPOLOGICAL INDICES OF TITANIA NANOTUBES

Molecular descriptors known as topological indices are graphical invariants which are used in chemistry, pharmaceutical sciences, materials science and engineering, because we can correlate these indices with a big number of chemical and physical properties of molecules. For titania nanotubes, we present the values of the most famous indices including Randic indices which are named after the chemist Milan Randic. Those indices are used to correlate the chemical structures and characteristics including boiling points and molar heats of formation. We focus on titania nanotubes, because they belong to the most studied compounds in materials science.
