| boron | <chemistry, element> Fifth element (Z=5) in the periodic table, has 5 protons, potential use as an aneutronic fuel. Also useful as a neutron-absorber. Abbreviation: B (13 Nov 1997) |
|---|---|
| boron compounds | Inorganic or organic compounds that contain boron as an integral part of the molecule. (12 Dec 1998) |
| boron neutron capture therapy | A technique for the treatment of neoplasms, especially gliomas and melanomas in which boron-10, an isotope, is introduced into the target cells followed by irradiation with thermal neutrons. (12 Dec 1998) |
| boronic acids | Inorganic or organic compounds that contain the basic structure rb(oh)2. (12 Dec 1998) |
| boronisation | <radiobiology> Energy confinement in a fusion plasma depends strongly on the average atomic number (Z) of the elements in the plasma. Boronisation refers to a process whereby boron (atomic number 5) is injected into a plasma and used to coat the walls of the reactor, the effect is that impurities from the reactor walls which enter the fusion plasma are primarily boron (which has a fairly low Z) rather than the higher-atomic-number metals typically used in reactor structures. Boronisation has been associated with improved fusion plasma performance. Boronisation is an example of Wall Conditioning. See: Boron, atomic number, wall conditioning, impurities. (09 Oct 1997) |
