| bleaching powder | A mixture of varying proportions of complexes of chlorine with calcium oxide and calcium hydroxide. Contains 24-37% available chlorine. Decomposes in moist conditions to liberate chlorine. Strong irritant due to chlorine vapors. Used for disinfecting drinking water, sewage etc.; in the bleaching of wood pulp, linen, cotton, straw, oils, soaps, and laundry; as an oxidiser; in destroying caterpillars; and as a decontaminant for mustard gas and similar substances. Synonym: bleaching powder. (05 Mar 2000) |

| goa powder | A bitter powder (also called araroba) found in the interspaces of the wood of a Brazilian tree (Andira araroba) and used as a medicine. It is the material from which chrysarobin is obtained. Origin: So called from Goa, on the Malabar coast, whither it was shipped from Portugal. Source: Websters Dictionary (01 Mar 1998) |
| powder | 1. The fine particles to which any dry substance is reduced by pounding, grinding, or triturating, or into which it falls by decay; dust. "Grind their bones to powder small." (Shak) 2. An explosive mixture used in gunnery, blasting, etc.; gunpowder. See Gunpowder. Atlas powder, Baking powder, etc. See Atlas, Baking, etc. Powder down, a boy formerly employed on war vessels to carry powder; a powder boy. Powder post. See Dry rot, under Dry. Powder puff. See Puff. Origin: OE. Poudre, pouldre, F. Poudre, OF. Also poldre, puldre, L. Pulvis, pulveris: cf. Pollen fine flour, mill dust, E. Pollen. Cf. Polverine, Pulverize. 1. To be reduced to powder; to become like powder; as, some salts powder easily. 2. To use powder on the hair or skin; as, she paints and powders. Source: Websters Dictionary (01 Mar 1998) |
| powder-posted | Affected with dry rot; reduced to dust by rot. See Dry rot, under Dry. (01 Mar 1998) |
| dover's powder | <alchemy> A powder of ipecac and opium, compounded, in the United States, with sugar of milk, but in England (as formerly in the United States) with sulphate of potash, and in France (as in Dr. Dover's original prescription) with nitrate and sulphate of potash and licorice. It is an anodyne diaphoretic. Origin: From Dr. Dover, an English physician. (04 Mar 1998) |
| james's powder | <medicine> Antimonial powder, first prepared by Dr. James, ar English physician. Synonym: fever powder. Source: Websters Dictionary (01 Mar 1998) |
| grating, diffraction | <microscopy> A series of narrow, close, equally spaced, diffracting slits or grooves capable of dispersing light into its spectrum. Diffraction gratings and their replicas are also used as standards in micrometry, especially in electron microscopy. (05 Aug 1998) |
| Convergent Beam Electron Diffraction | <microscopy> An electron probe is tightly focused on a transmission electron microscopy specimen and the resulting pattern of diffracted electrons is observed. The patterns contains information on the crystal symmetry and atomic and electronic structure of the sample. Regions as small as 0.2 nm may be examined. Acronym: CBED (05 Aug 1998) |
| X-ray diffraction | <investigation> Basis of powerful technique for determining the three dimensional structure of molecules, including complex biological macromolecules such as proteins and nucleic acids, that form crystals or regular fibres. Low angle X-ray diffraction is also used to investigate higher levels of ordered structure, as found in muscle fibres. (18 Nov 1997) |
| Selected Area Electron Diffraction | <technique> In this diffraction mode an aperture is used to define the area from which a diffraction pattern is to be recorded from a thin sample. This aperture is typically located in an image plane below the sample. Selected Area Electron Diffraction patterns are simple spot patterns and are of use in phase determination (lattice spacing measurement) and defect analysis (sample orientation). Acronym: SAED (05 Aug 1998) |
| diffraction | When a wave train passes an obstacle secondary waves are set up that interfere with the primary wave and give rise to bands of constructive and destructive interference. Around a point source of light, in consequence, is a series of concentric light and dark bands (coloured bands with white light), a diffraction pattern. (18 Nov 1997) |
| diffraction grating | <microscopy> An artificially produced periodic array of scattering centres capable of producing a pattern of diffracted energy, such as accurately ruled lines on a plane surface. (05 Aug 1998) |
| interference diffraction patterns | The patterns arising from the recombination of beams of light or other waves after they have been split and one set of rays have undergone a phase retardation relative to the other. Such patterns formed by simple objects give information on the correctness of the focus and the presence or absence of optical defects. (18 Nov 1997) |
| optical diffraction | A technique used to obtain information about repeating patterns. Diffraction of visible light can be used to calculate spacings in the object. (18 Nov 1997) |
| three-dimensional diffraction pattern | <optics> The diffraction pattern (of a point source) that appears in the three-dimensional space in and near the focal plane. For an aberration-free, diffraction- limited system, the slice of the diffraction pattern in the focal plane is the Airy disk and its surrounding diffraction rings. Above and below focus, the pattern changes periodically along the axis of the light beam so that bright and dark Airy-disk-like patterns appear alternately. The axial period of repeat is spaced twice as far apart as the radial period of repeat in the Airy disk and its diffraction rings (05 Aug 1998) |
