Occurrence data of nickel in feed and animal exposure assessment
EFSA Journal, Volume 17, Issue 6, June 2019., 2019 Abstract Nickel (Ni) is a silvery‐white, hard, ductile metal existing in oxidation states; in biological systems, Ni2+ is the prevalent form. All analytical results used to estimate animal dietary exposure were reported as Ni', without providing information on specific chemical species. Considering the data provided by Member states, among FoodEx level

On the nature of Ni⋯Ni interaction in a model dimeric Ni complex
Physical Chemistry Chemical Physics, 2011 A new dinuclear complex (NiC(5)H(4)SiMe(2)CHCH(2))(2) (2) was prepared by reacting nickelocene derivative [(C(5)H(4)SiMe(2)CH=CH(2))(2)Ni] (1) with methyllithium (MeLi). Good quality crystals were subjected to a high-resolution X-ray measurement. Subsequent multipole refinement yielded accurate description of electron density distribution.

The effects of some agrotechnical measures on the uptake of nickel by maize plants [PDF]
Journal of the Serbian Chemical Society, 2009 Nickel is a non-essential element in the nutrition of the majority of plant species and can be toxic to plants when its concentration in soils is high. Several soil properties have an effect on the uptake of this heavy metal by plants.
