Concurrent arhinia and choanal atresia in a day old male kid

Bulgarian 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 ...

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

Metal complexes as potential ligands : the deprotonation of aminephenolate metal complexes [PDF]

, 2010
The cationic nickel, copper and zinc complexes of tris-(2-hydroxybenzyl)-aminoethylamine (H6TrenSal) have been deprotonated using potassium hydroxide. The nickel complex can be sequentially deprotonated to form a series of compounds namely, [(H6TrenSal ...

XPS study of the chemical structure of the nickel/silicon interface [PDF]

, 1980
The chemical nature of the Ni/Si, Ni/Ni_(2)Si and Si/Ni_(2)Si interfaces have been investigated using x‐ray photoelectron spectroscopy. Peak position, line shapes, and envelope intensities are used to probe the compositional structure of these systems ...

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 ...

Relativity and Magnetism in Ni-Pd and Ni-Pt Alloys

, 2002
We show that the differences in the magnetic properties of Ni-Pd and Ni-Pt alloys arise mainly due to relativity. In particular, we find that the local magnetic moment of Ni increases with the addition of Pd in Ni-Pd while it decreases with the addition ...

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 ...
