| inorganic chemistry | The science concerned with compounds not involving carbon-containing molecules. (05 Mar 2000) |
|---|---|
| organic chemistry | <chemistry> A branch of chemistry that deals specifically with the structures, synthesis and reactions of carbon-containing compounds. (11 Jan 1998) |
| ecological chemistry | Chemistry that concentrates on the effects of woman-made chemicals on the environment as well as the development of agents that are not harmful to the environment. The study of the molecular interactions between species and between species and the environment. (05 Mar 2000) |
| epithermal chemistry | So-called "hot atom" chemistry; the science concerned with the chemical reactions of recoil atoms and free radicals produced in low energy nuclear processes. (05 Mar 2000) |
| action current | An electrical current induced in muscle fibres when they are effectively stimulated; normally it is followed by contraction. (05 Mar 2000) |
| alternating current | Electrical current which alternates direction periodically. (For instance, household electric current is AC alternating at 60 oscillations/sec (60 Hertz) in the United States, and 50 Hertz in many other countries.) Acronym: AC (09 Oct 1997) |
| anodal current | A current produced in tissues under the anode when the circuit is closed. (05 Mar 2000) |
| ascending current | The direction of current flow in a nerve when the anode is placed peripheral to the cathode, in contrast to descending current; the convention used is that current flows from positive to negative. Synonym: centripetal current. (05 Mar 2000) |
| axial current | The central rapidly moving portion of the bloodstream in an artery. (05 Mar 2000) |
| bootstrap current | <radiobiology> Currents driven in toroidal devices by neo-classical diffusion. They may amount to a substantial fraction of the net current in a tokamak reactor, thus lengthening the pulse time or decreasing the power needed for current drive. (09 Oct 1997) |
| calcium current | Inflow of calcium ions through specific calcium channels. Critically important in release of transmitter substance from presynaptic terminals. (18 Nov 1997) |
| galvanic current | See: direct current, galvanism. (05 Mar 2000) |
| radio frequency current drive | <radiobiology> Plasma waves in the radio-frequency range can be used to push plasma particles in such a way that current forms in the plasma, this is a method of non-inductive current drive which would allow for steady-state fusion reactors to operate. (09 Oct 1997) |
| gating current | <physiology> Small currents in the membrane just prior to the increase in ionic permeability, due to the movement of charged particles within the membrane. So called because they open the gates for current flow through ion channels. (20 Mar 1998) |
| M current | <physiology> Flow of potassium ions through M channels. (26 Mar 1998) |
