In this book, we mainly consider the computation of important topological indices of molecular structures. All the contexts can be divided into two topics: the first, we determine the eccentric version indices of Titania nano tubes; the second, the degree-based indices of Sierpinski networks are discussed. The conclusions achieved in our paper illustrate the promising prospects of the application for pharmacy engineering.
