International Journal of Electrochemical Science, 2011 Corrosion inhibition effect of alkaloids extract from Palicourea guianensis plant (AEPG) on C38 steel in 1 M HCl medium has been investigated by potentiodynamic polarization and electrochemical impedance spectroscopy. The polarization studies showed that

THE GROWTH OF TISSUE IN ACID MEDIA [PDF]
Journal of Experimental Medicine, 1913 Connective tissue cells of chick embryos and cells of a chicken sarcoma, proliferating in vitro, soon render acid the plasma about them, but they nevertheless continue to grow well. Evidently the tissue cell will withstand a considerably greater change in the reaction of the fluids about it than has usually been supposed.

The anodic dissolution of covellite in acidic, chloride solutions [PDF]
, 2010 An electrochemical study was conducted on a stationary, synthetically produced, covellite electrode in acidic, chloride solutions at ambient conditions to investigate the dissolution behaviour of the mineral over a surface potential range from the open ...

International Journal of Electrochemical Science, 2016 The process of pickling to remove corrosion products in metal pipes requires the use of an acidic solution together with corrosion inhibitors to protect the metal. However, the use of synthetic/commercial inhibitors has caused environmental pollution and
