Abstract Aromatic chemicals play indispensable roles in our daily lives, having broad applications household goods, textiles, healthcare, electronics and automotive, but their production currently relies on fossil resources that have heavy environmental burdens. Synthesis of aromatic from bio-based would be a viable approach to improve sustainability. However, very few methods are available for...

Conley in [6] constructed a complete Lyapunov function for a flow on compact metric space which is constant on orbits in the chain recurrent set and is strictly decreasing on orbits outside the chain recurrent set. This indicates that the dynamical complexity focuses on the chain recurrent set and the dynamical behavior outside the chain recurrent set is quite simple. In this paper, a similar r...

A topological descriptor is regarded as a numerical parameter derived by using mathematical tools from the molecular graph of different chemical structures. The theory paramount section chemistry. In this section, there are many parameters, that have very useful characteristics to study structure chemicals. article, we investigate indices concealed non-kekulean benzenoid hydrocarbon graph. We w...
