Faraday is most famous for his contributions to the understanding of electricity and electrochemistry. In this work he was driven by his belief in the uniformity of nature and the interconvertibility of various forces, which he conceived early on as fields of force.
In he succeeded in producing mechanical motion by means of a permanent magnet and an electric current—an ancestor of the electric motor.
From Punch , July 21, In the course of proving that electricities produced by various means are identical, Faraday discovered the two laws of electrolysis: the amount of chemical change or decomposition is exactly proportional to the quantity of electricity that passes in solution, and the amounts of different substances deposited or dissolved by the same quantity of electricity are proportional to their chemical equivalent weights.
In he and the classicist William Whewell worked out a new nomenclature for electrochemical phenomena based on Greek words, which is more or less still in use today— ion , electrode , and so on.
Faraday suffered a nervous breakdown in but eventually returned to his electromagnetic investigations, this time on the relationship between light and magnetism.
Although Faraday was unable to express his theories in mathematical terms, his ideas formed the basis for the electromagnetic equations that James Clerk Maxwell developed in the s and s. As Volta described his recent discoveries concerning electricity to the French National Institute, the delighted Napoleon demonstrated them on a voltaic pile. The voltaic pile produced a continuous current and thus opened two new areas of study: the chemical production of electricity and the effects of electricity on chemicals.
Volta reproduced this configuration in his new invention, which consisted of pairs of zinc and silver disks connected by brine-soaked cardboard. He placed those materials farthest apart that, when placed in contact, produced the strongest effects. A few years later Humphry Davy would argue in his electrical theory of chemical affinities that this similarity was no coincidence.
Michael Faraday, considered to be one of the greatest scientists in history. Sir Humphry Davy of the Royal Institution in London was one of the most important experimenters with the new voltaic battery, He realized that the production of electricity by the voltaic pile depended on the occurrence of chemical reactions, not just on the contact of different kinds of metals, as Volta had thought.
Allen Bard has published over peer-reviewed research papers, and he also has more than 30 patents to his name. The Center for Electrochemistry was founded in to create a cooperative group between the different types of concentrations in electrochemistry. Bard and his team were among the original researchers to leverage electrochemistry to produce light. The light produced a sensitive method of analysis that is now used for a slew of biological and medical purposes, such as determining if an individual has HIV and analyzing DNA.
The Bard group also comes in handy for electrochemical ways to observe chemical problems, investigating electro-organic chemistry, electroanalytical chemistry, and much more. He was chosen for the National Academy of Sciences in the year
