Collision excitation of c-CH(XA) by He.

Accurate modeling of anionic abundances in the interstellar and circumstellar media requires calculations of collisional data with the most abundant species that are usually He atoms and H molecules. In this paper, we focus on smaller cyclic molecular anion, c-CH, an astrophysical candidate, following the detection of larger CH carbon chains. From a new three-dimensional potential energy surface, the rotational (de-)excitation of the c-CH(XA) anion by collision with He is investigated.

A novel nanocomposite with superior electrocatalytic activity: A magnetic property based ZnFeO nanocubes embellished with reduced graphene oxide by facile ultrasonic approach.

Herein, a novel Zinc Ferrite nanocubes (ZnFeO NCs) decorated reduced graphene oxide (rGO) nanocomposite have been designed through a sonochemical method. After then, as-synthesized ZnFeO NCs/rGO was characterized by XPS, XRD, HRTEM and EIS. Furthermore, the ZnFeO NCs/rGO nanocomposite modified GCE (glassy carbon electrode) shows excellent electrochemical sensing performance towards biomarker of 4-nitroquinoline N-oxide (4-NQ) with fast detection.
