Otera's catalyst is an organostannane compound which has been used as a transesterification catalyst. This isothioscyanate compound is a member of a family of organostannanes

Glutamic acid is one of the 20 proteinogenic amino acids, and its codons are GAA and GAG. It is a non-essential amino acid.

Concurrent tandem catalysis (CTC) is a technique in chemistry which uses multiple catalysts on a single molecule in a one-pot vessel to produce a product otherwise not accessible by a single catalyst.

A catalytic converter is a device used to reduce the toxicity of exhaust emissions from an internal combustion engine.

Cathodic modification is the retardation of anodic reaction as the result of an increase in the ability of an alloy to be passivated by the introduction of an active cathode into the alloy e.g., the alloying of stainless steel and titanium with platinum group metals

The Schikorr reaction formally describes the conversion of the iron(II) hydroxide (Fe(OH)₂) into iron(II,III) oxide (Fe₃O₄). It can occur in the process of anaerobic corrosion of iron and carbon steel in various conditions.

Bethanization is a process to protect steel from corrosion by plating it with zinc.

In the context of corrosion, passivation is the spontaneous formation of a hard non-reactive surface film that inhibits further corrosion. This layer is usually an oxide or nitride that is a few nanometers thick.

A reference electrode is an electrode which has a stable and well-known electrode potential. The high stability of the electrode potential is usually reached by employing a redox system with constant (buffered or saturated) concentrations of each participants of the redox reaction.

The Severinghaus electrode is an electrode that measures carbon dioxide. It utilizes a CO₂-sensitive glass electrode in a surrounding film of bicarbonate solution covered by a thin plastic carbon dioxide permeable membrane, but impermeable to water and electrolytic solutes.

A glass electrode is a type of ion-selective electrode made of a doped glass membrane that is sensitive to a specific ion. It is an important part of the instrumentation for chemical analysis and physico-chemical studies.

A black layer is a coat on the filament of the indirectly heated hot cathode in a cathode ray tube, intended to optimise the output of electrons from the cathode, thus minimising the energy consumption and heat generated while maximising the picture brightness.

Carbocatalysis is a form of catalysis that uses heterogeneous graphite, graphene, graphene oxide, or closely related carbon materials for the transformation or synthesis of organic or inorganic substrates. The catalysts are characterized by their high surface areas, surface functionality and large, aromatic basal planes.

Raney nickel is a solid catalyst composed of fine grains of a nickel-aluminium alloy, used in many industrial processes. It is used as an  catalyst for the hydrogenation of vegetable oils in industrial processes.

Electroforming is a metal forming process that forms thin parts through the electroplating process. The part is produced by plating a metal skin onto a base form, known as a mandrel, which is removed after plating.

A galvanic cell, derives electrical energy from chemical reactions taking place within the cell. It generally consists of two different metals connected by a salt bridge, or individual half-cells separated by a porous membrane.

A nickel-metal hydride cell is a type of rechargeable battery similar to the nickel-cadmium cell. The NiMH battery uses a hydrogen-absorbing alloy for the negative electrode instead of cadmium.

Biosensor is a device for the detection of an analyte that combines a biological component with a physicochemical detector component.

A black start is the process of restoring a power station to operation without relying on external energy sources.

The Hall-Héroult process is the major industrial process for the production of aluminium. It involves dissolving alumina in molten cryolite, and electrolysing the molten salt bath to obtain pure aluminium metal.

Isomerases just rearrange the existing atoms of a molecule, that is, create isomers of the starting material.

A suppressor grid is a grid used in a thermionic valve (also called vacuum tube) to suppress secondary emission. A suppressor grid is also called the antidynatron grid, as it helps to reduce the dynatron effect.

A fluoride selective electrode is a type of ion selective electrode sensitive to the concentration of the fluoride ion. A common example is the lanthanum fluoride electrode.

Caseinase is an enzyme that is produced by the human body to help break down milk.

Chymotrypsin is a digestive enzyme that can perform proteolysis. It is synthesized in the pancreas by protein biosynthesis as a precursor called chymotrypsinogen that is enzymatically inactive.
