The Castner Gold Medal on Industrial Electrochemistry is an biennial award given by the Electrochemical Technology Group of Society of Chemical Industry (SCI) to an authority on applied electrochemistry or electrochemical engineering connected to industrial research. [1] The award is named in honor of Hamilton Castner, a pioneer in the field of industrial electrochemistry, who patented in 1892 the mercury cell for the chloralkali process. Castner was an early member of SCI. [1]
The medal is presented in a public lecture, usually at the annual Electrochem conference, which is organised by the Royal Society of Chemistry (RSC) Electrochemistry Interest Group and the SCI Electrochemical Technology Group. When this is not possible, the medal presentation and lecture takes place at SCI's headquarters.
The medal's design was conceived by Humphrey Paget by commission of SCI. [2] At least until 1958, the award was called Castner Gold Medal. [3]
To the date, 23 academics and industrialists have received the award. [4]
An electrochemical cell is a device that generates electrical energy from chemical reactions. Electrical energy can also be applied to these cells to cause chemical reactions to occur. Electrochemical cells that generate an electric current are called voltaic or galvanic cells and those that generate chemical reactions, via electrolysis for example, are called electrolytic cells.
In electrochemistry, the electrochemical potential (ECP), μ, is a thermodynamic measure of chemical potential that does not omit the energy contribution of electrostatics. Electrochemical potential is expressed in the unit of J/mol.
The chloralkali process is an industrial process for the electrolysis of sodium chloride (NaCl) solutions. It is the technology used to produce chlorine and sodium hydroxide, which are commodity chemicals required by industry. Thirty five million tons of chlorine were prepared by this process in 1987. The chlorine and sodium hydroxide produced in this process are widely used in the chemical industry.
Nafion is a brand name for a sulfonated tetrafluoroethylene based fluoropolymer-copolymer discovered in the late 1960s by Dr. Walther Grot of DuPont. Nafion is a brand of the Chemours company. It is the first of a class of synthetic polymers with ionic properties that are called ionomers. Nafion's unique ionic properties are a result of incorporating perfluorovinyl ether groups terminated with sulfonate groups onto a tetrafluoroethylene (PTFE) backbone. Nafion has received a considerable amount of attention as a proton conductor for proton exchange membrane (PEM) fuel cells because of its excellent chemical and mechanical stability in the harsh conditions of this application.
A proton-exchange membrane, or polymer-electrolyte membrane (PEM), is a semipermeable membrane generally made from ionomers and designed to conduct protons while acting as an electronic insulator and reactant barrier, e.g. to oxygen and hydrogen gas. This is their essential function when incorporated into a membrane electrode assembly (MEA) of a proton-exchange membrane fuel cell or of a proton-exchange membrane electrolyser: separation of reactants and transport of protons while blocking a direct electronic pathway through the membrane.
A flow battery, or redox flow battery, is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane. Ion transfer inside the cell occurs through the membrane while both liquids circulate in their own respective space. Cell voltage is chemically determined by the Nernst equation and ranges, in practical applications, from 1.0 to 2.43 volts. The energy capacity is a function of the electrolyte volume and the power is a function of the surface area of the electrodes.
Bernard S. Baker is an American electrochemist who was a pioneer in the field of electrochemistry. He was a founder and served as president, chief executive officer and chairman of Energy Research Corporation, developer and manufacturer of direct fuel cells (MCFC) used to generate electric power. Power plants based on his concepts are providing electricity in distributed generation locations throughout the world.
The Castner–Kellner process is a method of electrolysis on an aqueous alkali chloride solution to produce the corresponding alkali hydroxide, invented by American Hamilton Castner and Austrian Carl Kellner in the 1890s. Due to lower energy cost and fewer environmental concerns, the Castner–Kellner process is being replaced gradually with membrane electrolysis.
The Electrochemical Society is a learned society based in the United States that supports scientific inquiry in the field of electrochemistry solid-state science and related technology. The Society membership comprises more than 8,000 scientists and engineers in over 85 countries at all degree levels and in all fields of electrochemistry, solid-state science and related technologies. Additional support is provided by institutional members including corporations and laboratories.
Gas diffusion electrodes (GDE) are electrodes with a conjunction of a solid, liquid and gaseous interface, and an electrical conducting catalyst supporting an electrochemical reaction between the liquid and the gaseous phase.
Chlorine gas can be produced by extracting from natural materials, including the electrolysis of a sodium chloride solution (brine) and other ways.
Electrochemical engineering is the branch of chemical engineering dealing with the technological applications of electrochemical phenomena, such as electrosynthesis of chemicals, electrowinning and refining of metals, flow batteries and fuel cells, surface modification by electrodeposition, electrochemical separations and corrosion.
