The 1913 Liberty Head nickel is an American five-cent piece which was produced in extremely limited quantities unauthorized by the United States Mint, making it one of the best-known and most coveted rarities in American numismatics.In 1972, one specimen of the five cent coin became the first coin to sell for over US$100,000; in 1996, another specimen became the first …

Nickel wurde erstmals 1751 von Axel Frederic Cronstedt rein dargestellt und nach dem Mineral Kupfernickel (schwedisch kopparnickel, heute Nickelin) benannt, in dem er das bis dahin unbekannte Metall fand.. Mit der Bezeichnung Kupfernickel belegten die mittelalterlichen Bergleute das Erz, das zwar aussah wie Kupfererz, aus dem sich aber kein Kupfer gewinnen …

Nickel sulfide is an inorganic compound with the formula NiS. It is a black solid that is produced by treating nickel(II) salts with hydrogen sulfide.Many nickel sulfides are known, including the mineral millerite, which also has the formula NiS.Aside from being useful ores, nickel sulfides are the products of desulfurization reactions, and are sometimes used as catalysts.

The SAE steel grades system is a standard alloy numbering system (SAE J1086 - Numbering Metals and Alloys) for steel grades maintained by SAE International.. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels. These efforts were similar and overlapped significantly.

Sodium–nickel chloride (Zebra) battery. A lower-temperature variant of molten-salt batteries was the development of the ZEBRA (originally, "Zeolite Battery Research Africa"; later, the "Zero Emissions Batteries Research Activity") battery in 1985, originally developed for …

Un oxyde [1], [2] est un composé de l'oxygène avec un élément moins électronégatif que lui, c'est-à-dire tous sauf le fluor [a] et lui-même. Le terme « oxyde » désigne également l'ion oxyde O 2−. Un oxyde contenant une proportion d'oxygène moins élevée ou plus élevée qu'un oxyde normal est appelé respectivement sous-oxyde [3] ou peroxyde [4], [5], [6].

Iron-56 (56 Fe) is the most common isotope of iron.About 91.754% of all iron is iron-56. Of all nuclides, iron-56 has the lowest mass per nucleon.With 8.8 MeV binding energy per nucleon, iron-56 is one of the most tightly bound nuclei. Nickel-62, a relatively rare isotope of nickel, has a higher nuclear binding energy per nucleon; this is consistent with having a higher mass-per …
