The inhibition efficiency and synergistic behaviour of 10-4M Atropine methochloride was carried out using mass loss and polarisation methods in the presence of (i) metal ions, Ni2+and Cu2+between 10-2M to 10-6M concentrations, (ii) different concentrations of metal ions and 10-3M I-, 10-3M Cl-and 10-3M Br-solutions and (iii) different metal ions, 10-3M I-and at three different temperatures. The analysis reveals that the inhibition efficiency of Atropine methochloride was maximum at 10-2M in 5 hours of immersion period. Halides decreased the corrosion rate of mild steel in Sulphuric acid. The decrease is maximum with 10-3M I-. As the temperature increased from 298K to 308K, the inhibition efficiency gradually decreased. The inhibitor was found to be effective up to 303K

A facile, green and environmentally‐friendly protocol for the preparation of ceria doped multi‐walled carbon nanotubes (2.5%CeO2/MWCNTs) composite catalysts are developed. The synthesized catalyst materials have been characterized by using P‐XRD, SEM, TEM and BET analysis. Further, the composite was utilized as a highly efficient and reusable heterogeneous nano‐catalyst for the synthesis of pyridine‐3‐carboxamide derivatives by multicomponent condensation of acetoacetanilide, ammonium acetate, substituted aromatic aldehyde and ethyl cyanoacetate via one‐pot reaction under ethanol solvent conditions at R.T. The remarkable advantages of this green protocol exhibits operational simplicity, easy workup procedure, inexpensive, evading of toxic solvents, shorter reaction times (≤ 15 mins), excellent yields and also avoidance of column chromatography. Furthermore, the catalyst was recyclable and reusability endured for a minimum of six consecutive cycles without significant loss in the catalytic activity.
