Nick translation [ 1 ] (or head translation ), developed in 1977 by Peter Rigby and Paul Berg, is a tagging technique in molecular biology in which DNA polymerase I is used to replace some of the nucleotides of a DNA sequence with their labeled analogues, creating a tagged DNA sequence which can be used as a probe in f... | https://en.wikipedia.org/wiki/Nick_translation |
Nickel(II) chromate (NiCrO 4 ) is an acid-soluble compound, red-brown in color, with high tolerances for heat. It and the ions that compose it have been linked to tumor formation and gene mutation, particularly to wildlife. [ 2 ]

Nickel(II) iodide is an inorganic compound with the formula NiI 2 . This paramagnetic black solid dissolves readily in water to give bluish-green solutions, [ 1 ] from which crystallizes the aquo complex [Ni(H 2 O) 6 ]I 2 (image above). [ 2 ] This bluish-green colour is typical of hydrated nickel(II) compounds. Nickel... | https://en.wikipedia.org/wiki/Nickel(II)_iodide |
Nickel (II) nitrate is the inorganic compound Ni(NO 3 ) 2 or any hydrate thereof. In the hexahydrate, the nitrate anions are not bonded to nickel. Other hydrates have also been reported: Ni(NO 3 ) 2 . 9H 2 O, Ni(NO 3 ) 2 . 4H 2 O, and Ni(NO 3 ) 2 . 2H 2 O. [ 3 ]

Nickel(II) perchlorate is a collection of inorganic compounds with the chemical formula of Ni(ClO 4 ) 2 (H 2 O) x . Its colors of these solids vary with the degree of hydration. For example, the hydrate forms cyan crystals, the pentahydrate forms green crystals, but the hexahydrate (Ni(ClO 4 ) 2 ·6H 2 O) forms blue cry... | https://en.wikipedia.org/wiki/Nickel(II)_perchlorate |
Nickel (III) oxide is the inorganic compound with the formula Ni 2 O 3 . It is not well characterized, [ 1 ] and is sometimes referred to as black nickel oxide . Traces of Ni 2 O 3 on nickel surfaces have been mentioned. [ 2 ] [ 3 ]
Nickel (III) oxide has been studied theoretically since the early 1930s, [ 4 ] support... | https://en.wikipedia.org/wiki/Nickel(III)_oxide |
The Nickel Directive was a European Union directive regulating the use of nickel in jewellery and other products that come into contact with the skin. Since 1 June 2009, it has been subsumed into the REACH Regulation , specifically item 27 of Annex XVII to that regulation. Nevertheless, the term Nickel Directive is sti... | https://en.wikipedia.org/wiki/Nickel_Directive |
Nickel allergy is any of several allergic conditions provoked by exposure to the chemical element nickel . Nickel allergy often takes the form of nickel allergic contact dermatitis ( Ni-ACD ), a form of allergic contact dermatitis (ACD).

Nickel aluminide refers to either of two widely used intermetallic compounds, Ni 3 Al or NiAl, but the term is sometimes used to refer to any nickel–aluminium alloy. These alloys are widely used because of their high strength even at high temperature, low density, corrosion resistance, and ease of production.
