| die | 1. To pass from an animate to a lifeless state; to cease to live; to suffer a total and irreparable loss of action of the vital functions; to become dead; to expire; to perish; said of animals and vegetables; often with of, by, with, from, and rarely for, before the cause or occasion of death; as, to die of disease or hardships; to die by fire or the sword; to die with horror at the thought. "To die by the roadside of grief and hunger." (Macaulay) "She will die from want of care." (Tennyson) 2. To suffer death; to lose life. "In due time Christ died for the ungodly." (Rom. V. 6) 3. To perish in any manner; to cease; to become lost or extinct; to be extinguished. "Letting the secret die within his own breast." (Spectator) "Great deeds can not die." (Tennyson) 4. To sink; to faint; to pine; to languish, with weakness, discouragement, love, etc. "His heart died within, and he became as a stone." (1 Sam. Xxv. 37) "The young men acknowledged, in love letters, that they died for Rebecca." (Tatler) 5. To become indifferent; to cease to be subject; as, to die to pleasure or to sin. 6. To recede and grow fainter; to become imperceptible; to vanish; often with out or away. "Blemishes may die away and disappear amidst the brightness." (Spectator) 7. To disappear gradually in another surface, as where moldings are lost in a sloped or curved face. Synonym: To expire, decease, perish, depart, vanish. Origin: OE. Deyen, dien, of Scand. Origin; cf.

| van der Waals attraction | <chemistry> Electrodynamic forces arise between atoms, molecules and assemblies of molecules due to their vibrations giving rise to electromagnetic interactions, these are attractive when the vibrational frequencies and absorptions are identical or similar, repulsive when nonidentical. Other interactions originally proposed by van der Waals were included in this name, but these are usually separated into the Coulomb's force, the Keesom force and the London force. Only the last is of electrodynamic nature. Probably important in holding lipid membranes into that structure and possibly in other interactions, for example cell adhesion. Electrodynamic forces between large scale assemblies can be of relatively long range nature. (18 Nov 1997) |
| van der Waals' forces | First postulated by van der Waals in 1873 to explain deviations from ideal gas behaviour seen in real gases; the attractive force's between atoms or molecules other than electrostatic (ionic), covalent (sharing of electrons), or hydrogen bonding (sharing a proton); generally ascribed to dipolar and dispersion effects, π-electrons, etc.; these relatively nondescript force's contribute to the mutual attraction of organic molecules. Synonym: London forces. (05 Mar 2000) |
