Iridium-based catalysts for oxygen evolution reaction in acidic media: Mechanism, catalytic promotion effects and recent progress

open access: yesNano Research Energy, 2023
Iridium (Ir)-based catalysts are highly efficient for the anodic oxygen evolution reaction (OER) due to high stability and anti-corrosion ability in the strong acid electrolyte. Recently, intensive attention has been directed to novel, efficient, and low-

THE GROWTH OF TISSUE IN ACID MEDIA [PDF]

open access: yesJournal 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.

Investigation on the dynamic behaviour and corrosion characteristics of hexagonal boron nitride (h-BN) and zirconium dioxide (ZrO2) reinforced Al7075 composite

open access: yesJournal of Alloys and Metallurgical Systems, 2023
Stir casting was used to make Al7075 composites with 3% h-BN and different amounts of ZrO2 (2%, 4%, and 6% by weight). Damping behaviour and corrosion resistance corresponding to the reinforcement percentage were investigated. Damping was evaluated using

Evaluation of Eulychnia acida Phil. (Cactaceae) Extracts as Corrosion Inhibitors for Carbon Steel in Acidic Media.

open access: yesInternational 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
