Galvanism - Wikipedia
Galvanism is a term invented by the late 18th-century physicist and chemist Alessandro Volta to refer to the generation of electric current by chemical action. [2] The term also came to refer to the discoveries of its namesake, Luigi Galvani, specifically the generation of electric current within biological organisms and the contraction ...

Composed of a stack of alternating discs of copper and zinc separated by cardboard soaked in brine, it was a game-changer in the study of electricity and its inventive applications. Giovanni Aldini, Galvani’s nephew, defended and built upon his …
What is Galvanism, And How Did it Inspire Mary Shelley’s …
2022年6月16日 · Giovanni Aldini was demonstrating a phenomenon known as galvanism, which is defined as the contraction of muscles by the application of electrical currents. The effect was named by Alessandro Volta after scientist Luigi Galvani, who investigated the effect of electricity on dissected animals in the 1780's and 1790's.
Galvanic corrosion - Wikipedia
Galvanic corrosion (also called bimetallic corrosion or dissimilar metal corrosion) is an electrochemical process in which one metal corrodes preferentially when it is in electrical contact with another, in the presence of an electrolyte.
Galvanism, in Nicholson's British Encyclopedia (1809)
In short, they determined that the gases evolved were oxyden and hydrogen, and in proportions fit to constitute water. These discoveries established the chemical nature of the galvanic action in England; and they soon spread over all Europe. The above experiments were repeated by Mr. Cruikshank, of Woolwich.

2018年4月9日 · But when treating of its chemical agency, he represents it as ‘a modification of the exertion of chemical forces’. ( Caloric , viii) This shows not only the complexity of the phenomena under consideration, but the challenges in reaching consensus about how to interpret and understand these effects.
nerally received chemical theory of galvanism. 3. Dr. WOLLASTON assumes that positive electricity is set at liberty by the combination of oxygen with one of the metals. This principle is frequently true, but in many cases it is totally false. This will be rendered obvious by the following experiments. EXPERIMENT III.
Galvanization - Wikipedia
Galvanization or galvanizing (also spelled galvanisation or galvanising) [1] is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are coated by submerging them in a bath of hot, molten zinc. [citation needed] Protective action.
