Bronzing :: Bronzing (n.) The act or art of communicating to articles in metal, wood, clay, plaster, etc., the appearance of bronze by means of bronze powders, or imitative painting, or by chemical processes..

Zoochemistry :: Zoochemistry (n.) Animal chemistry; particularly, the description of the chemical compounds entering into the composition of the animal body, in distinction from biochemistry..

Electro-metallurgy :: Electro-metallurgy (n.) The act or art precipitating a metal electro-chemical action, by which a coating is deposited, on a prepared surface, as in electroplating and electrotyping; galvanoplasty..

Mechanical :: Mechanical (a.) Pertaining to, governed by, or in accordance with, mechanics, or the laws of motion; pertaining to the quantitative relations of force and matter, as distinguished from mental, vital, chemical, etc.; as, mechanical principles; a mechanical theory; mechanical deposits..

Calorimeter :: Calorimeter (n.) An apparatus for measuring the amount of heat contained in bodies or developed by some mechanical or chemical process, as friction, chemical combination, combustion, etc..

Formaldehyde :: Formaldehyde (n.) A colorless, volatile liquid, H2CO, resembling acetic or ethyl aldehyde, and chemically intermediate between methyl alcohol and formic acid..

Irritant :: Irritant (n.) Any agent by which irritation is produced; as, a chemical irritant; a mechanical or electrical irritant..

Voltaism :: Voltaism (n.) That form of electricity which is developed by the chemical action between metals and different liquids; voltaic electricity; also, the science which treats of this form of electricity; -- called also galvanism, from Galvani, on account of his experiments showing the remarkable influence of this agent on animals..

Separation :: Separation (n.) Chemical analysis.

Nucleus :: Nucleus (n.) A body, usually spheroidal, in a cell or a protozoan, distinguished from the surrounding protoplasm by a difference in refrangibility and in behavior towards chemical reagents. It is more or less protoplasmic, and consists of a clear fluid (achromatin) through which extends a network of fibers (chromatin) in which may be suspended a second rounded body, the nucleolus (see Nucleoplasm). See Cell division, under Division..

Hemin :: Hemin (n.) A substance, in the form of reddish brown, microscopic, prismatic crystals, formed from dried blood by the action of strong acetic acid and common salt; -- called also Teichmann's crystals. Chemically, it is a hydrochloride of hematin..

Chemolysis :: Chemolysis (n.) A term sometimes applied to the decomposition of organic substance into more simple bodies, by the use of chemical agents alone..

Stearolic :: Stearin (n.) One of the constituents of animal fats and also of some vegetable fats, as the butter of cacao. It is especially characterized by its solidity, so that when present in considerable quantity it materially increases the hardness, or raises the melting point, of the fat, as in mutton tallow. Chemically, it is a compound of glyceryl with three molecules of stearic acid, and hence is technically called tristearin, or glyceryl tristearate..

Diazotize :: Diazotize (v. t.) To subject to such reactions or processes that diazo compounds, or their derivatives, shall be produced by chemical exchange or substitution..

Vacuole :: Vacuole (n.) A small air cell, or globular space, in the interior of organic cells, either containing air, or a pellucid watery liquid, or some special chemical secretions of the cell protoplasm..

Composition :: Composition (n.) A mass or body formed by combining two or more substances; as, a chemical composition..

Mechanico-chemical :: Mechanico-chemical (a.) Pertaining to, connected with, or dependent upon, both mechanics and chemistry; -- said especially of those sciences which treat of such phenomena as seem to depend on the laws both of mechanics and chemistry, as electricity and magnetism..

Allotropy :: Allotropy (n.) The property of existing in two or more conditions which are distinct in their physical or chemical relations.

Nitrogen :: Nitrogen (n.) A colorless nonmetallic element, tasteless and odorless, comprising four fifths of the atmosphere by volume. It is chemically very inert in the free state, and as such is incapable of supporting life (hence the name azote still used by French chemists); but it forms many important compounds, as ammonia, nitric acid, the cyanides, etc, and is a constituent of all organized living tissues, animal or vegetable. Symbol N. Atomic weight 14. It was formerly regarded as a permanent noncon

Electrolysis :: Electrolysis (n.) The act or process of chemical decomposition, by the action of electricity; as, the electrolysis of silver or nickel for plating; the electrolysis of water..
