Corrosion inhibition capacity of two heterocyclic oximes on copper in nitric acid: Electrochemical, quantum chemical and surface morphological investigations

Varghese, C Sini; K, Joby Thomas; Raphael, Vinod; Shanmughan, Shaju (Growing Science, 2019-03)

Two heterocyclic oximes (E)-N-hydroxy-1-(pyridin-2-yl)methanimine (Hp2ylm) and (E)-N-hydroxy-1-(pyridin-3-yl)methanimine (Hp3ylm) were synthesized from pyridine-2-carbaldehyde and pyridine-3-carbaldehyde, respectively. ...
Efficacies of sodium nitrite and sodium citrate–zinc acetate mixture to inhibit steel rebar corrosion in simulated concrete interstitial solution contaminated with NaCl

Maliekkal, Binsi Paulson; Kakkassery, Joby Thomas; Palayoor, Vinod Raphael (Springer, 2018-04-04)

Investigations were carried out to compare the effectiveness of compounds such as sodium nitrite, trisodium citrate (TSC) and TSC–zinc acetate to inhibit the corrosion of steel rebar in simulated concrete interstitial ...
