Simple manufacturing and metal type-dependent properties of M3(OH)2V2O7•nH2O (M; Co, Ni, Cu, Zn) nanostructures [PDF]

Nanochemistry Research, 2020
M3(OH)2V2O7·nH2O ( M : Co, Ni, Cu, Zn) nanostructures were synthesized by a simple and economic chemical precipitation route. For Co and Ni compounds, very small (~9 nm), irregularly shaped and poor crystalline nanoparticles occurred, probably due to ...

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
