| paper | 1. A substance in the form of thin sheets or leaves intended to be written or printed on, or to be used in wrapping. It is made of rags, straw, bark, wood, or other fibrous material, which is first reduced to pulp, then molded, pressed, and dried. 2. A sheet, leaf, or piece of such substance. 3. A printed or written instrument; a document, essay, or the like; a writing; as, a paper read before a scientific society. "They brought a paper to me to be signed." (Dryden) 4. A printed sheet appearing periodically; a newspaper; a journal; as, a daily paper. 5. Negotiable evidences of indebtedness; notes; bills of exchange, and the like; as, the bank holds a large amount of his paper. 6. Decorated hangings or coverings for walls, made of paper. See Paper hangings, below. 7. A paper containing (usually) a definite quantity; as, a paper of pins, tacks, opium, etc. 8. A medicinal preparation spread upon paper, intended for external application; as, cantharides paper. Paper is manufactured in sheets, the trade names of which, together with the regular sizes in inches, are shown in the following table. But paper makers vary the size somewhat. In the manufacture of books, etc, a sheet, of whatever size originally, is termed, when folded once, a folio; folded twice, a quarto, or 4to; three times, an octavo, or 8vo; four times, a sextodecimo, or 16mo; five times, a 32mo; three times, with an offcut folded twice and set in, a duodecimo, or 12mo; four times, with an offcut folded three times and set in, a 24mo. Paper is often used adjectively or in combination, having commonly an obvious signification; as, paper cutter or paper-cutter; paper knife, paper-knife, or paperknife; paper maker, paper-maker, or papermaker; paper mill or paper-mill; paper weight, paper-weight, or paperweight, etc. Business paper, checks, notes, drafts, etc, given in payment of actual indebtedness; opposed to accommodation paper. Fly paper, paper covered with a sticky preparation, used for catching flies. Laid paper. See Laid. <botany> Paper birch, any wasp which makes a nest of paperlike material, as the yellow jacket. Paper weight, any object used as a weight to prevent loose papers from being displaced by wind, or otherwise. Parchment paper. See Papyrine. Tissue paper, thin, gauzelike paper, such as is used to protect engravings in books. Wall paper. Same as Paper hangings, above. Waste paper, paper thrown aside as worthless or useless, except for uses of little account. Wove paper, a writing paper with a uniform surface, not ribbed or watermarked. Origin: F. Papier, fr. L. Papyrus papyrus, from which the Egyptians made a kind of paper, Gr. Cf. Papyrus. Source: Websters Dictionary (01 Mar 1998) |
| paper chromatography | <technique> Separation method in which filter paper is used as the support. A type of chromatography in which the stationary phase is a sheet of special-grade filter paper. It is in all other aspects similar to thin-layer chromatography. Not a very sensitive method, but historically important as one of the first methods available for separating natural compounds.

| paper plate | A thin plate of ethmoid bone forming part of the medial wall of the orbit and the lateral wall for the ethmoidal labyrinth. Synonym: lamina orbitalis ossis ethmoidalis, lamina papyracea, orbital lamina of ethmoid bone, orbital layer of ethmoid bone, orbital plate, paper plate, papyraceous plate. (05 Mar 2000) |
| chromatography paper | Used in paper chromatography. Synonym: high quality filter paper. Congo red paper, paper impregnated with Congo red; used as a pH indicator, changing from blue-violet at 3.0 to red at 5.0. Filter paper, an unsized paper used in pharmacy and chemistry for filtering solutions; many varieties are used for paper chromatography. (05 Mar 2000) |
| cigarette-paper scars | Atrophic scar's in the skin at sites of minor lacerations over the knees, shins, and elbows of persons with Ehlers-Danlos syndrome. Synonym: papyraceous scars. (05 Mar 2000) |
| potassium nitrate paper | Paper impregnated with potassium nitrate that is ignited to produce fumes inhaled as treatment for asthma. Synonym: potassium nitrate paper, saltpeter paper. Occluding paper, an inked paper or ribbon interposed between natural or artificial teeth to determine tooth contacts. Synonym: articulating paper. (05 Mar 2000) |
| saltpeter paper | Paper impregnated with potassium nitrate that is ignited to produce fumes inhaled as treatment for asthma. Synonym: potassium nitrate paper, saltpeter paper.

| nitrocellulose paper | <apparatus> Paper with a high non-specific absorbing power for biological macromolecules. Very important as a receptor in blot transfer methods. Bands are transferred from a chromatogram or electropherogram either by blotting on nitrocellulose sheets or by electrophoretic transfer. The replica can then be used for sensitive analytical detection methods. (18 Nov 1997) |
| electrophoresis, paper | Electrophoresis in which paper is used as the diffusion medium. This technique is confined almost entirely to separations of small molecules such as amino acids, peptides, and nucleotides, and relatively high voltages are nearly always used. (12 Dec 1998) |
| Abbe test plate | <equipment> A long, wedge-shaped coverslip about 0.20 mm thick at one end and 0.10 to 0.12 mm at the other end coated chemically with a silver film on which are ruled horizontal lines. at each variation in thickness of 0.01 mm there are vertical lines. By means of oblique illumination and by focusing on different portions of the plate, it is possible to determine the optimum coverslip thickness for any objective and also, for microscopes with drawtubes, the tube length for best objective performance. The approximate freedom from spherical and chromatic aberrations can also be estimated. Small isolated bits of silver near the edges of the lines form good objects for the star test (05 Aug 1998) |
