Editorial: 100 years of polarography

The young journal Electrochemical Science Advances copublished by Wiley-VCH and Chemistry Europe has had a great start. Its constitution reflects the increasing interest in electrochemical research development. content is therefore devoted not only to fundamental electrochemistry but (importantly) consequential applications like generation storage of electricity, photovoltaics, corrosion, sensors, analysers, electrochromism, (photo)electrocatalysis, electrosynthesis, photo- spectroelectrochemistry, molecular electronics, alternative electrodes etc. beginning dated about three centuries back, its development connected with names Luigi Galvani (1737–1798), Alessandro Volta (1745–1827), Humphry Davy (1778-1829), John F. Daniell (1790–1845), Michael Faraday (1791–1867), many others. In 19th century, was rather part physics general studies electricity—at first (Volta, Daniell), then combination biology (Galvani), later electrolyses metal electrodeposition (Faraday), surface effects, conductivity electrolytes current collection this new symbolically 100th anniversary polarography invented at Charles University, Prague, Jaroslav Heyrovský (Nobel Prize 1959). February 1922, polarographic curve recorded, where for time, plotted against potential (i-E curve) offering simultaneously qualitative as well quantitative analytical data. Therefore, year 1922 considered true start modern chemical sciences. instrument itself—polarograph—was that time fully automatic device after filling cell, connecting electrodes, setting conditions (scan rate, initial final potential, sensitivity, drop size etc.) switching ON instrument, whole experiment including photographic recording running automatically. After electroanalysis, continued toward organic redox characterization molecules, investigation relationship between their structure properties. Because electrochemistry, an classic thermal chemistry, uses “pure” electrons generated or accepted electrode reduction oxidation reactions, respectively, it represents approach tool suitable all branches chemistry. Although currently goes through enormous fascinating both applied sciences, still, original means voltammetry utilizing mercury working (today mostly computer-controlled) will have permanent position among standard techniques research. This issue containing results actual should illustrate rich crop growing tree cultivated from roots. author declares no conflict interest.
