The difference between insulators and semiconductors is only that the forbidden band gap between the valence band and conduction band is larger in an insulator, so that fewer electrons are found there and the electrical conductivity is lower.

It consists of at least two main parts, the " base ", which is the part that makes contact with the device being cooled, usually made of a high conductivity metal such as aluminum or copper and in some cases silver as is found in many newer blocks.

The detailed mechanisms of this type of failure have been studied extensively by Merchant for metal cutting, and the principles found can be directly applied to coatings.

In certain obscure magical writings of Egyptian origin ἀβραξάς or ἀβρασάξ is found associated with other names which frequently accompany it on gems ; it is also found on the Greek metal tesseræ among other mystic words.

This word is usually conceded to be derived from the Hebrew ( Aramaic ), meaning " Thou art our father " ( אב לן את ), and also occurs in connection with Abrasax ; the following inscription is found upon a metal plate in the Carlsruhe Museum:

When this discovery was followed up in 1870, on the neighbouring Santorin ( Thera ), by representatives of the French School at Athens, much pottery of a class now known immediately to precede the typical late Aegean ware, and many stone and metal objects, were found.

A map of Cyprus in the later Bronze Age ( such as is given by J. L. Myres and M. O. Richter in Catalogue of the Cyprus Museum ) shows more than 25 settlements in and about the Mesaorea district alone, of which one, that at Enkomi, near the site of Salamis, has yielded the richest Aegean treasure in precious metal found outside Mycenae.

The most common oxidation state of carbon in inorganic compounds is + 4, while + 2 is found in carbon monoxide and other transition metal carbonyl complexes.

Stromeyer found the new element as an impurity in zinc carbonate ( calamine ), and, for 100 years, Germany remained the only important producer of the metal.

The metal was named after the Latin word for calamine, since the metal was found in this zinc compound.

* All six strings are made from nylon, or nylon wrapped with metal, as opposed to the metal strings found on other acoustic guitars.

The number of ligands that react with a central metal atom can be found using the 18-electron rule, saying that the valence shells of a transition metal will collectively accommodate 18 electrons, whereas the symmetry of the resulting complex can be predicted with the crystal field theory and ligand field theory.

The expected increase of fuel efficiency of the engine ( caused by the higher temperature, as shown by Carnot's theorem ) could not be verified experimentally ; it was found that the heat transfer on the hot ceramic cylinder walls is higher than the transfer to a cooler metal wall.

Heavy metals ( Tl, Cd, Hg, ...) are often found as trace elements in common metal sulfides ( pyrite ( FeS < sub > 2 </ sub >), zinc blende ( ZnS ), galena ( PbS ), ...) present as secondary minerals in most of the raw materials.

A silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements on Earth.

Examples include staged multi-caches ; underwater caches, caches located 50 feet ( 15 m ) up a tree, caches found only after long offroad drives, caches on high mountain peaks, caches located in challenging environments ( such as Antarctica or north of the Arctic Circle ), and magnetic caches attached to metal structures and / or objects.

A lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in zirconium minerals.

Very rarely the element can be found as grains of native ( free ) metal, but these are not of commercial importance.

Soon it was found that it was better to coat the exterior of the jar with metal foil ( Watson, 1746 ), leaving the ( accidentally ) impure water inside acting as a conductor, connected by a chain or wire to an external terminal, a sphere to avoid losses by corona discharge.

Addenbrook ( 1922 ) found that in a dissectible jar made of paraffin wax, or glass baked to remove moisture, the charge remained on the metal plates.

The free element ( metal ) is not found naturally on Earth, as it is highly reactive ( though once produced, it is coated in a thin layer of oxide ( see passivation ), which partly masks this reactivity ).

In contrast to the more strict definition proposed by IUPAC, which requires a d-block metal and a sandwich structure, the term metallocene and thus the denotation-ocene, is applied in the chemical literature also to non-transition metal compounds, such as Cp < sub > 2 </ sub > Ba, or structures where the aromatic rings are not co-planar, such as found in manganocene or titanocene dichloride ( Cp < sub > 2 </ sub > TiCl < sub > 2 </ sub >).
