Topological indices are numerical values that correlate a molecular graph’s physical and chemical properties. Titania nanotubes are a well-known semiconductor with a wide range of technological applications including biomedical devices, dye-sensitized solar cells, and so on. We offer two new graph invariants in this study known as the ‘Reformulated Y-index’ and ‘Reformulated S-index’. We calculate some special graphs and the Reformulated Y-index and S-index for some graph operations like as Join, Cartesian Product, Corona product, Corona join product, Subdivision vertex join and evaluate the Titania Nanotubes in Reformulated indices.
