Innovative self-assembled silver nanoparticles on reduced graphene oxide hydrogel nanocomposite for improved electrochemical hydrogen generation and sensing
Characterization of GO and rGO
The XRD pattern was analysed for a qualitative assessment of the as-prepared GO and rGO Fig. 1(a). GO displays a distinct peak at 8.5°, attributable to the (001) diffraction peaks of GO, resulting from the presence…

Linear model based on neighborhood ABS index for graph energy in benzenoid hydrocarbons and maximum index cactus graphs
We examine the sharp upper bound on the NABS index of a cactus with q vertices and l cycles in this section.
The cactus graph with q vertices and l cycles is represented as \(\mathfrak {C}^0(q,l)\), whereas the set with q vertices and t pendent…
