Chemistry typically is divided into several major sub-disciplines. There are also several main cross-disciplinary and more specialized fields of chemistry. Analytical chemistry is the analysis of material samples to gain an understanding of their chemical composition and structure. Analytical chemistry incorporates standardized experimental methods in chemistry. These methods may be used in all subdiciplines of chemistry, excluding purely theoretical chemistry. Biochemistry is the study of the chemicals, chem ...

Chemistry (derived from the Arabic word kimia, alchemy, where al is Arabic for the) is the science of matter that deals with the composition, structure, and properties of substances and with the transformations that they undergo. In the study of matter, chemistry also investigates its interactions with energy and itself (see physics, biology). Because of the diversity of matter, which is mostly composed of different combinations of atoms, chemists often study how atoms of different chemical elements interact to fo ...

Wasabi (Japanese: 山葵 or 和佐比; Wasabia japonica, Cochlearia wasabi, or Eutrema japonica) is a member of the cabbage family. Known as Japanese horseradish, its root is used as a spice and has an extremely strong flavor. Its hotness is different from that of the chile pepper, which burns the tongue; wasabi produces vapors that burn the sinus cavity instead. The plant grows naturally along stream beds in mountain river valleys in Japan. There are also other species used, such as W. koreana, and W. t ...

See text Acorus is a genus of monocot flowering plants. This genus was once placed within the family Araceae (aroids), but more recent phylogenies place it in its own family Acoraceae and order Acorales, of which it is the sole genus. Common names include Calamus and Sweet Flag. The name 'acorus' is derived from the Greek word 'acoron', a name used by Dioscorides, which in turn was derived from 'coreon', meaning 'pupil', because it was used in herbal medicin ...

Aluminium or aluminum (Symbol Al) (see the spelling section below) is a silvery and ductile member of the poor metal group of chemical elements. Its atomic number is 13. Aluminium is found primarily as the ore bauxite and is remarkable for its resistance to oxidation (due to the phenomenon of passivation), its strength, and its light weight. Aluminium is used in many industries to make millions of different products and is very important to the world economy. Structural components made from aluminium are vital to the aer ...

Carbon is a chemical element in the periodic table that has the symbol C and atomic number 6. An abundant nonmetallic, tetravalent element, carbon has several allotropic forms: Diamond (hardest known natural mineral). Structure: each atom is bonded tetrahedrally to four others, making a 3-dimensional network of puckered six-membered rings of atoms. Graphite (one of the softest substances). Structure: each atom is bonded trigonally to three other atoms, making a 2-dimensional network of flat s ...

In organic chemistry, butyl is a four-carbon alkyl substituent with chemical formula -C4H9. It is the substituent form of the alkane butane. For example: This is methyl tertiary butyl ether (an ether). The butyl group (which is tert-butyl, see below) is to the left of the oxygen atom; the rest of the molecule can be thought of as a methoxy group. There are four isomers of the butyl substituent. Butyl is the largest substituent for which trivial names are commonly u ...

In polymer chemistry and Process Engineering, curing refers to the toughening or hardening of a polymer material by cross-linking of polymer chains, brought about by chemical additives, ultraviolet radiation or heat. In rubber, the curing process is also called vulcanization. In food preparation, curing refers to various preservation and flavoring processes, especially of meat or fish, by the addition of a combination of salt, sugar and either nitrate or nitrite. Many curing processes also involve smoking. The etymology of the term is unclear, but it is thought to derive from the same Latin cura ...

For the battery, see alkaline battery The word alkali can mean:- In chemistry, an alkali is a specific type of base, formed as a carbonate, hydroxide or other ionic salt of an alkali metal or alkali earth metal element. The word alkali or the adjective alkaline are frequently used to refer to all bases, since most common bases are alkalis, although such use is really a synecdoche. In the western parts of the USA, natural soda or potash deposits (soda and potash themselves are both alkali salt ...

Alchemy is an early protoscientific and philosophical discipline combining the elements of chemistry, metallurgy, physics, medicine, astrology, semiotics, mysticism, and art. Alchemy has been practiced in ancient Egypt, India, and China, in Classical Greece and Rome, in the Islamic Empire, and then in Europe up to the 19th century — in a complex network of schools and philosophical systems spanning at least 2500 years. The alchemists did not follow what is now known as the scientific method, and much of the "knowledge" they p ...

An ion is an atom or group of atoms with a net electric charge. A negatively charged ion, which has more electrons in its electron shell than it has protons in its nucleus, is known as an anion, for it is attracted to anodes, and a positively charged ion, which has fewer electrons than protons, is known as a cation (pronounced cat-eye-on), for it is attracted to cathodes. An ion with a single atom is a monatomic ion and an ion with more than one is a polyatomic ion. The process of converting into ions and the stat ...

Science (from Latin scientia - knowledge) refers to a system of acquiring knowledge - based on empiricism, experimentation, and methodological naturalism - aimed at finding out the truth. The basic unit of knowledge is the theory, which is a hypothesis that is predictive. The term science also refers to the organized body of knowledge humans have gained by such research. Most scientists feel that scientific investigation must adhere to the scientific method, a process for evaluating empirical knowledge under the w ...

The thiol group is the sulfur analog of the hydroxyl group (-OH) found in alcohols. Since sulfur and oxygen belong to the same periodic table group, they share some similar chemical bonding properties. The chemistry of thiols is thus related to the chemistry of alcohols: thiols form thioethers, thioacetals and thioesters, which are analogous to ethers, acetals, and esters. Furthermore, a thiol group can react wi ...

Aluminium - Etymology / Nomenclature history. In 1808, Humphry Davy originally proposed the name alumium while trying to isolate the new metal electrolytically from the mineral alumina. In 1812 he changed the name to aluminum to match its Latin root. The same year, an anonymous contributor to the Quarterly Review objected to aluminum, and proposed the name aluminium. Aluminium, for so we shall take the liberty of writing the word, in preference to aluminum, which has a less class ...

The chemicals in wasabi that provide its unique flavor are the isothiocyanates, including: 6-methylthiohexyl isothiocyanate, 7-methylthioheptyl isothiocyanate and 8-methylthioocytl isothiocyanate. Research has shown that isothiocyanates have beneficial effects such as inhibiting microbe growth. This may partially explain why wasabi is traditionally served with seafood, which spoils quickly. However, if the quality of one's seafood is questionable, one should not eat it raw, with or without wasabi. It is ...
