Ni-catalyzed asymmetric C-P cross-coupling reaction via Ni(I)/Ni(III) two-electron pathway

open access: yes, 2023
Nickel demonstrates excellent performance in C-C or C-X cross-coupling reactions involving a SET process. However, the Ni(I)/Ni(III) two-electron pathway, which does not require light irradiation, is still rare, particularly in the asym-metric version ...

Preparation and temperature cycling reliability of electroless Ni(P) under bump metallization [PDF]

open access: yes, 2007
The reliability of electroless Ni(P) under-bump metallization (UBM) was evaluated via temperature cycling and solder bump shear strength tests. Commercial diodes and dummy dies fabricated in-house were used as substrates for the electroless Ni(P) UBM ...

Occurrence data of nickel in feed and animal exposure assessment

open access: yesEFSA 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

open access: yesPhysical 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.

Concurrent arhinia and choanal atresia in a day old male kid

open access: yesBulgarian Journal of Veterinary Medicine, 2022
Arhinia is a congenital nasal developmental anomaly that is seldom reported in literature, and espe-cially not reported in domestic animals. This report describes a case of concurrent occurrence of con-genital arhinia and choanal atresia in a day-old ...

Glycerol Electrooxidation at Structured Nickel Electrodes and the Effect of Geometry on the Selectivity of Product

open access: yesChemElectroChem, Volume 12, Issue 17, September 1, 2025.
The geometry of additively manufactured nickel electrodes influences the selectivity of glycerol electrooxidation. An increased surface area at zero depth correlates with higher selectivity for C2 and C3 products, as well as improved Faradaic efficiency.
