Energy dispersive x-ray analysis

== Description ==
Energy dispersive X-ray microanalysis (EDX) can be used to determine which elements are present in a sample. 
A scanning electron microscope (SEM) is usually used in EDX. An electron beam falls on the sample generating a small amount of X-rays. The X-rays can identify the various elements which are present in the sample. 
EDX can show whether a sample contains, for example, chemical elements such as lead, copper, arsenic, tin, antimony, cobalt and chromium. However, this is not sufficient to show which molecular or crystalline forms have been used. EDX must be used in conjunction with other examination or molecular analysis in order to find out which chemical compounds are present. 
== Synonyms and related terms ==

== Description ==
A relatively small oak, Quercus robur, grown abundantly in parks and on roadsides in England. English oak has a coarse, but straight grain that is usually a rich brown color. Flat sawn timber has a distinctive figuring while radial cut lumber has silver grain lines. The wood has a high gallic acid content that will corrode iron and other contacting metals. English oak is widely used in furniture, paneling, railway sleepers, cabinet, musical instruments, and ship building. The bark is used for tanning and dyeing.

English pink

== Description ==
1) Another name for Dutch pink, a natural yellow lake pigment. Although English pink was considered inferior by some because it was paler and coarser in consistency (Harley 1982). This term fell into disuse by the end of the 18th century. 
2) A pastel reddish white color ceramic pigment. English pink, or chrome-tin pink, was developed about 1790 by a potter in Staffordshire. The color is produced when chromic oxide and tin oxide fuse in the presence of lime. The color is dependent on particle size and is not always uniform. Pink can also be formed by the combination of chromium and zircon oxides. Chrome-tin pink was occasionally used as a pale pink artists color.

English poplar

== Description ==
A hardwood tree, Populus nigra, of the willow family native to Europe. Classified as a black poplar because of its bark color, the English poplar is a medium to large sized deciduous tree reaching 20-30 m with trunks averaging 1.5 m. Poplar leaves are diamond shaped and green on both sides. The typical tree grows quickly and is very specifc to species and growing locations. In general, poplar produces a soft, lightweight wood that is easy to work. The yellowish white wood has a fine, uniform grain but it is prone to warping. It is primarily used for paneling, light construction, packing crates and paper pulp. A yellowish dye can be extracted from the fresh leaves of the poplar. On wool, it produces a brass color with a chrome mordant and a yellow-brown color with an alum mordant. The extract does not dye cotton.
== Synonyms and Related Terms ==
Populus nigra; peuplier noir (Fr.); álamo negro (Esp.); choupo negro (Port.); pioppo nero (It.); black poplar; Lombardy poplar
== Physical and Chemical Properties ==
* Color: Heartwood is light brown; sapwood in pale yellow to white
* Grain/Texture: Grain is straight to slightly interlocked. Medium texture with low luster.
* Durability: Not resistant to rot or insect attack.
* Density = 25 ppcf
==Working Properties==
* Easy to work with hand and machine tools
* Sharp cutters are necessary when planing to avoid fuzzy surfaces.
* Wood has a tendency to warp and distort during drying. 
* Glues and finishes well.

English walnut

== Description ==
A deciduous hardwood tree, Juglans regia, known for its timber and its nuts. The English walnut is native to Europe and parts of Asia. The wood from the English walnut tree is a uniform, deep brown color with a medium texture and a close, straight grain. It is strong but easy to work and polishes to a high gloss. Walnut wood is used for furniture, veneers, cabinets, paneling and gum stocks. Burrs, called oyster veneers, are especially prized in the furniture trade. Other portions of the tree also have commercial value. The nut kernels are used for cooking and the pale yellow fast-drying oil expressed from the nuts is used for artists paints. Tannins and dyes are extracted from the walnut hulls and shells that produces a brown color. Ground nut shells have been used as a soft abrasive and a plastic filler.
== Synonyms and Related Terms ==
Juglans regia; noyer (Fr.); nogal (Esp.); nogueira (Port.); noce (It.); French walnut; Queen Ann's cabinet wood; Persian walnut; oyster veneer
== Physical and Chemical Properties ==

* Bark=light gray with flattened ridges in diamond shaped pattern 
* Leaves=pinnate with 5 to 7 ovate leaflets (15 to 20 cm long). 
* Fruit=round, edible nut (5 cm diameter) with bright green husk, matures in fall. 
* Wood has low acidity. 
* Density = 38-48 ppcf
==Working Properties==
* Easy to work provided the grain is straight and regular. Planer tearout can sometimes be a problem when surfacing pieces with irregular or figured grain. 
* Glues, stains, and finishes well, (though walnut is rarely stained).

Enstatite

== Description ==
A pyroxene mineral composed of magnesium silicate. Enstatite was first described by G.A. Kenngott in 1855. It occurs naturally in metamorphic rocks and meterorites. The mineral is usually a gray, pale green, or brown in color although a gemstone quality emerald green variety occurs rarely. Weathered enstatite can have a metallic luster and is called bronzite. Enstatite can alter to form steatite. Steatite may also be heated to form enstatite.

Enzyme

== Description ==
A unique class of componds that originate in living cells and are capable of catalyzing specific chemical reactions in other organic compounds. More than 1000 enzymes have been identified. Most are proteins, but a few newly discovered ones are ribonucleic acids. Enzymes are classified by the types of reactions they catalyze: 
1) Hydrolases (proteolytic enzymes) accelerate reactions with water, 
2) Oxidoreductases regulate oxidation and reduction reactions usually by acting as an oxygen acceptor or donor, 
3) Transferases aid in the transferring of specific functional groups, 
4) Lyases remove or add specific functional groups, 
5) Ligases combine one or more molecules and 
6) Isomerases can racemize compounds. 
Enzymes have long been used for fermentation and more recently have been used to remove stains and to breakdown and solubilize otherwise insoluble materials.
