91Voltage-gated ion channel — Voltage gated ion channels are a class of transmembrane ion channels that are activated by changes in electrical potential difference near the channel; these types of ion channels are especially critical in neurons, but are common in many types… …
92Maraging steel — Maraging steels (a portmanteau of martensitic and aging ) are steels (iron alloys) which are known for possessing superior strength and toughness without losing malleability, although they cannot hold a good cutting edge. Aging refers to the… …

94Crystal momentum — In solid state physics crystal momentum or quasimomentum[1] is a momentum like vector associated with electrons in a crystal lattice. It is defined by the associated wave vectors k of this lattice, according to (where is the reduced Planck s… …
95Non-coordinating anion — Anions that interact weakly with cations are termed non coordinating anions, although a more accurate term is weakly coordinating anion .[1] Non coordinating anions are useful in studying the reactivity of electrophilic cations. They are commonly …
96Tetrahedral symmetry — A regular tetrahedron has 12 rotational (or orientation preserving) symmetries, and a total of 24 symmetries including transformations that combine a reflection and a rotation.The group of symmetries that includes reflections is isomorphic to S 4 …
97DNA-binding domain — A DNA binding domain (DBD) is an independently folded protein domain that contains at least one motif that recognizes double or single stranded DNA. A DBD can recognize a specific DNA sequence (a recognition sequence) or have a general affinity… …
