General and Inorganic Chemistry – Laboratory Techniques
... In 1892 a conference in Geneva laid the basis for an internationally accepted system of organic nomenclature, but at that time there was nothing comparable for inorganic nomenclature. Thus, many ad hoc systems had developed for particular rather than general purposes („Geneva nomenclature”). The nee ...

History of electrochemistry
Electrochemistry, a branch of chemistry, went through several changes during its evolution from early principles related to magnets in the early 16th and 17th centuries, to complex theories involving conductivity, electric charge and mathematical methods. The term electrochemistry was used to describe electrical phenomena in the late 19th and 20th centuries. In recent decades, electrochemistry has become an area of current research, including research in batteries and fuel cells, preventing corrosion of metals, the use of electrochemical cells to remove refractory organics and similar contaminants in wastewater electrocoagulation and improving techniques in refining chemicals with electrolysis and electrophoresis.
