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

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

ChemElectroChem, 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.

Ni‐Based Catalysts for 5‐Hydroxymethylfurfural Electrooxidation Coupled with Hydrogen Production

ChemElectroChem, Volume 12, Issue 13, July 3, 2025.
The co‐electrolysis of H2O and 5‐hydroxymethylfurfural (HMF) using Ni‐based catalysts, under alkaline conditions, co‐produces low‐carbon hydrogen and furandicarboxylic acid. This review delves into the electrooxidation mechanism of HMF electrooxidation, presents recent advancements in the performance of Ni‐based catalysts and highlights the effects of ...

Surface Properties of p‐GaN and Formation of Nickel Metal Contacts

Advanced Materials Interfaces, Volume 12, Issue 13, July 14, 2025.
The amount of C, O, and Mg–O bonds on the surface of p‐GaN can be reduced while still maintaining the surface morphology by potassium hydroxide (KOH) wet chemical treatment. Heating this surface with Ni on top in ultra‐high vacuum (UHV) results in a crystalline Ga‐Ni alloy and diffusion of Ga, which creates vacancies close to valence band leading to ...
