|Electrochemistry deals in chemical reactions which occurs in a solution at the interface of an electron conductor (the electrode: a metal or a semiconductor) and an ionic conductor (the electrolyte). These reactions include electron transfer between the electrode and the electrolyte. Hence electrochemistry deals with interactions between electrical energy and chemical change and vice versa. If a chemical reaction takes place by applying external voltage, as in electrolysis, or if a voltage is generated by a chemical reaction as in a battery, it is an electrochemical reaction. Chemical reactions where electrons are transferred between molecules are called oxidation-reduction (redox) reactions. Electrochemistry deals with situations where redox reactions are differentiated in space or time, linked by an external electric circuit. The open access journals are peer reviewed scholarly journals of Chemical Sciences Journal. The top open access journals are freely available on the public internet domain, allowing any end users to read, download, copy, distribute, prink, search or link to the full texts of the articles. These provide high quality, meticulously reviewed and rapid publication, to cater the insistent need of scientific community. These journals are indexed with all their citations noted. The top open access journals are indexed in SCOPUS, COPERNICUS, CAS, EBSCO and ISI.
