| ionic | Relating to an ion. (05 Mar 2000) |
| ionic coupling | <chemistry> The same as electrical coupling. (18 Nov 1997) |
| ionic medication | Movement of ions as a result of an applied electric field. For example the delivery of a charged molecule from the end of a micropipette without hydraulic flow. (18 Nov 1997) |
| ionic strength | Symbolised as g/2 or I and set equal to 0.5σmizi2, where mi equals the molar concentration and zi the charge of each ion present in solution; if molar concentrations (ci) are used instead of molality (and the solution is dilute), then I == 0.5(1/ρo)σcizi2 where ρo is the density of the solvent; a number of biochemically important events (e.g., protein solubility and rates of enzyme action) vary with the ionic strength of a solution. (05 Mar 2000) |
| ionidium | <botany> A genus of violaceous plants, chiefly found in tropical America, some species of which are used as substitutes for ipecacuanha. Origin: NL. Cf. Iodine. Source: Websters Dictionary (01 Mar 1998) |
| ionisation | <chemistry, radiobiology> Any process by which a neutral atom gains or loses electrons, thus acquiring a net charge, as the dissociation of a substance in solution into ions or ion production by the passage of radioactive particles. High temperatures, electrical discharges or nuclear radiations can cause ionisation. (16 Dec 1997) |
| ionisation energy | <radiobiology> Generally refers to the amount of energy required to strip a particular electron from an atom. The first ionisation energy is a commonly used quantity in many fields of physics and chemistry. Typically measured in electron-volts. Equivalent to the atomic binding energy of the electron. (09 Oct 1997) |
| ionise | To separate into ions; to dissociate atoms or molecules into electrically charged atoms or radicals. (05 Mar 2000) |
| ionised atom | <chemistry> An atom that possesses an electrostatic charge as a result of loss or gain of electrons; e.g., H+, Calcium, Cl-, O2-. (05 Mar 2000) |
| ionised calcium | <biochemistry> The ionised calcium represents the calcium (Ca++) that is the metabolically active calcium. Normal values for ionised calcium in the bloodstream should be 4.4 to 5.3 mg/dl for adults and 4.4 to 6.0 mg/dl for children. Elevations may be seen in hyperparathyroidism, metastatic bone tumour, milk-alkali syndrome, multiple myeloma, Paget's disease, sarcoidosis, PTH-secreting tumours (paraneoplastic syndrome) and vitamin D intoxication. Lower than normal values may be seen in hypoparathyroidism, malabsorption, osteomalacia, pancreatitis, renal failure, rickets and vitamin D deficiency. (27 Sep 1997) |
| ionising radiation | <radiobiology> Radiation sufficiently energetic to dislodge electrons from an atom. Ionising radiation includes x and gamma radiation, electrons (beta radiation), alpha particles (helium nuclei) and heavier charge atomic nuclei. Neutrons ionise indirectly by colliding with atomic nuclei. Alpha and gamma radiation are far more effective at producing ionisation (and therefore more likely to cause tissue or cell damage) than beta radiation or neutrons. (16 Dec 1997) |
| ionium | Former term for thorium-230. Origin: G. Ion, going (05 Mar 2000) |
| ionization | <chemistry, radiobiology> Any process by which a neutral atom gains or loses electrons, thus acquiring a net charge, as the dissociation of a substance in solution into ions or ion production by the passage of radioactive particles. High temperatures, electrical discharges or nuclear radiations can cause ionisation. (16 Dec 1997) |
| ionization chamber | A chamber for detecting ionization of the enclosed gas; used for determining intensity of ionizing radiation. (05 Mar 2000) |
| spectrometry, mass, secondary ion | A mass-spectrometric technique that is used for microscopic chemical analysis. A beam of primary ions with an energy of 5-20 kiloelectronvolts (kev) bombards a small spot on the surface of the sample under ultra-high vacuum conditions. Positive and negative secondary ions sputtered from the surface are analyzed in a mass spectrometer in regards to their mass-to-charge ratio. (12 Dec 1998) |
|---|---|
| sulfonium ion | A compound in which a sulfur atom has three single covalent bonds and therefore has a positive charge analogous to the nitrogen of an ammonium compound; e.g., S-adenosyl-l-methionine. (05 Mar 2000) |
| sulfur-ferric ion oxidoreductase | <enzyme> From thiobacillus ferrooxidans; catalyses the production of sulfite and fe(2+) from elemental sulfur and fe(3+) Registry number: EC 1.8.99.- Synonym: sf oxidoreductase, sulfite-ferric ion oxidoreductase (26 Jun 1999) |
| oxonium ion | <chemistry> A positively charged ion that is water with an additional hydrogen atom (H3O). (09 Oct 1997) |
| tetraethylammonium ion | A monovalent cation widely used in neurophysiology as a specific blocker of potassium channels. It is similar in size to the hydrated potassium ion and gets stuck (reversibly) in the channels. (18 Nov 1997) |
| field ion microscope | <instrument> Type of microscopy in which the specimen is illuminated with ions, often gallium ions, that are focussed electrostatically. The ions remove components of the specimen, lower atomic masses first. These are imaged and provide information on elemental distribution with a resolution of perhaps 30 nm. (18 Nov 1997) |
| ligand gated ion channel | A transmembrane ion channel whose permeability is increased by the binding of a specific ligand, typically a neurotransmitter at a chemical synapse. The permeability change is often drastic, such channels let through effectively no ions when shut, but allow passage at up to 10exp7 ions sexp 1 when a ligand is bound. Recently, the receptors for both acetylcholine and GABA have been found to share considerable sequence homology, implying that there may be a family of structurally related ligand gated ion channels. (18 Nov 1997) |
| light-ion fusion | <radiobiology> Light-Ion-Beam-Driven Inertial Confinement fusion, using beams of light ions driven at implosion targets. Pulsed-power driven accelerators are relatively efficient and cost-effective, but beam-focusing is a technical hurdle for this approach. (09 Oct 1997) |
