| electrostatic analyser | <radiobiology> A device which filters an electron beam (band-pass), permitting only electrons within a narrow energy (velocity) range to pass. (09 Oct 1997) |
| electrostatic confinement | <radiobiology> An approach to fusion based on confining charged particles by means of electric fields, rather than the magnetic fields used in magnetic confinement. (09 Oct 1997) |
| electrostatic field | <radiobiology> The region surrounding an electric charge in which another charge experiences a force. (16 Dec 1997) |
| electrostatic force | <radiobiology> Like charges in close proximity produce forces of repulsion between them. Consequently if two surfaces bear appreciable and approximately equal densities of charged groups on their surfaces appreciable forces of repulsion may occur between them. The range of these forces is determined in the main by the ionic strength of the intervening medium, forces being of minimal range at high ionic strength. The forces are effective over approximately twice the double layer thickness. See: DLVO theory. (18 Nov 1997) |
| electrostatic lens | <physics> A lens employing a permanent magnet to produce a potential field capable of deflecting electron rays to form an image of an object. (cf. Electromagnetic lens). (05 Aug 1998) |
| electrostatic unit | The unit in an absolute system (CGS) of unit's utilizing static electricity; e.g., statampere, statcoulomb, statfarad, stathenry, statvolt. (05 Mar 2000) |
| electrostatic wave | <radiobiology> Longitudinal oscillations appearing in a plasma due to a perturbation of electric neutrality. For a cold unmagnetised plasma, or at large wavelengths, the frequency of these waves is by definition the plasma frequency. (09 Oct 1997) |
| acylmercaptan bond | A high energy bond formed by the condensation of a carboxyl group (-COOH) and a mercaptan (or thiol) group (-SH); widely formed in the course of intermediary metabolism, notably in the oxidation of fats, where the -SH is part of coenzyme A and the -COOH is part of the fatty acid being oxidised. (05 Mar 2000) |
| apolar bond | <chemistry> The attractive force between molecules due to the close positioning of non-hydrophilic portions of the two molecules. (09 Oct 1997) |
| bond | 1. That which binds, ties, fastens,or confines, or by which anything is fastened or bound, as a cord, chain, etc.; a band; a ligament; a shackle or a manacle. "Gnawing with my teeth my bonds in sunder, I gained my freedom." (Shak) 2. The state of being bound; imprisonment; captivity, restraint. "This man doeth nothing worthy of death or of bonds." 3. A binding force or influence; a cause of union; a uniting tie; as, the bonds of fellowship. "A people with whom I have no tie but the common bond of mankind." (Burke) 4. Moral or political duty or obligation. "I love your majesty According to my bond, nor more nor less." (Shak) 5. A writing under seal, by which a person binds himself, his heirs, executors, and administrators, to pay a certain sum on or before a future day appointed. This is a single bond. But usually a condition is added, that, if the obligor shall do a certain act, appear at a certain place, conform to certain rules, faithfully perform certain duties, or pay a certain sum of money, on or before a time specified, the obligation shall be void; otherwise it shall remain in full force. If the condition is not performed, the bond becomes forfeited, and the obligor and his heirs are liable to the payment of the whole sum. 6. An instrument (of the nature of the ordinary legal bond) made by a government or a corporation for purpose of borrowing money; as, a government, city, or railway bond. 7. The state of goods placed in a bonded warehouse till the duties are paid; as, merchandise in bond. 8. The union or tie of the several stones or bricks forming a wall. The bricks may be arranged for this purpose in several different ways, as in English or block bond (Fig. 1), where one course consists of bricks with their ends toward the face of the wall, called headers, and the next course of bricks with their lengths parallel to the face of the wall, called stretchers; Flemish bond (Fig.2), where each course consists of headers and stretchers alternately, so laid as always to break joints; Cross bond, which differs from the English by the change of the second stretcher line so that its joints come in the middle of the first, and the same position of stretchers comes back every fifth line; Combined cross and English bond, where the inner part of the wall is laid in the one method, the outer in the other. 9. <chemistry> A unit of chemical attraction; as, oxygen has two bonds of affinity. It is often represented in graphic formulae by a short line or dash. See Diagram of Benzene nucleus, and Valence. Arbitration bond. See Arbitration. Bond crediter, a debt contracted under the obligation of a bond. Bond (or lap) of a slate, the distance between the top of one slate and the bottom or drip of the second slate above, i. E, the space which is covered with three thicknesses; also, the distance between the nail of the under slate and the lower edge of the upper slate. Bond timber, timber worked into a wall to tie or strengthen it longitudinally. Synonym: Chains, fetters, captivity, imprisonment. Origin: The same word as band. Cf. Band, Bend.

| bond length | This is the distance between the nuclei of two atoms which have formed bonds with each other. (09 Oct 1997) |
| electrostatic bond | a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains to electron to form a negative ion |
