Korean Journal of Mathematics, 2016 Summary: Let \(R\) be a ring. It is well-known that \(R\) is \(NI\) if and only if \(\sum_{i=0}^nRa_iR\) is a nil ideal of \(R\) whenever a polynomial \(\sum_{i=0}^na_ix^i\) is nilpotent, where \(x\) is an indeterminate over \(R\). We consider a condition which is similar to the preceding one: \( \sum_{i=0}^nRa_iR\) contains a nonzero nil ideal of \(R\)

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.
