the basic Roman unit of weight; after 268 BC it was about 5,076 English grains or equal to 0.722 pounds avoirdupois (0.329 kg). This pound was brought to Britain and other provinces where it became the standard for weighing gold and silver and for use in all commercial transactions. The abbreviation lb for pound is derived from libra. One-twelfth of the libra, the Roman uncia, is the ancestor of the English ounce
in physical chemistry, a colloid (aggregate of very fine particles dispersed in a continuous medium) in which the particles are solid and the dispersion medium is fluid. If the dispersion medium is water, the colloid may be called a hydrosol; and if air, an aerosol. Lyophobic (Greek: "liquid-hating") sols are characterized by particles that are not strongly attracted to molecules of the dispersion medium and that are relatively easily coagulated and precipitated. Lyophilic ("liquid-loving") sols are more stable and more closely resemble true solutions. Many sols are intermediate between lyophobic and lyophilic types. Compare gel.
