In the 1790s Luigi Galvani lay a dead frog on a table. Also on the table was a static electricity generator. An assistant accidentally touched the nerves of the frog with a scalpel and the muscles of the frog contracted . 6 ( 2011 ) 6332 - 6349 International Journal of ELECTROCHEMICAL SCIENCE www.electrochemsci.org Electrochemical Realkalisation of Carbonated Concrete: an Alternative Approach to Pr evention of Reinfor 10 ( 201 5 ) 1684 - 1695 International Journal of ELECTROCHEMICAL SCIENCE www.electrochemsci.org Electrochemical Activity of Modified Glassy Carbon Electrodes with Covalent Bonds Towa rds Molecular Do Now. : 5 color pencils.
