With the activation gate closed and the inactivation gate open, the Na+ channel is once again in its deactivated state, and is ready to participate in another action potential.

Stainless Steel Passivation Stainless steel is passivated through a cleaning cycle to remove oils, grease, compounds, lubricants, and residue followed by a nitric or a citric acid bath or a by an oxidant that removes free iron and contaminates. Passivation is performed on clean stainless steel, providing the surface has been thoroughly cleaned or descaled.

Standard Practice for Cleaning, Descaling, and Passivation of Stainless Steel Parts, Equipment, and Systems 1.1.1.3 Passivation is the chemical treatment of a stainless steel with a mild oxidant, such as a nitric acid solution, for the purpose of enhancing the spontaneous formation of the protective passive film. Such chemical treatment is generally not necessary for the formation of the passive film.

Neuroscience For Kids After a chemical is released, it must be inactivated. Inactivation can be through a reuptake mechanism or by an enzyme that stops the action of the chemical. If the chemical is applied on the post-synaptic membrane, it should have the same effect as when it is released by a neuron.. Enzymatic degradation (deactivation): a specific enzyme changes the structure of the neurotransmitter so it is not recognized by the receptor. For example, acetylcholinesterase is the enzyme that breaks acetylcholine into choline and acetate.

Electropolishing vs Passivation The Passivation Process. Passivation of metal, similar to electropolishing, is a metal finishing operation that many industries specify for their parts. Passivation is a chemical process designed to increase the corrosion resistance of stainless steel parts. To passivate stainless steel parts, the parts are placed in a basket and submerged in a nitric or citric acid bath.
