Geochemistry of Ni in the Cretaceous-Tertiary succession Fiskeler (Fish Clay) at Stevns Klint (Denmark): cheto-smectite of the black marl [PDF]
Journal of the Serbian Chemical Society, 2006 The Cretaceus-Tertiary (KT) boundary at Stevns Klint (the Højerup succession), Fiskeler, consists of a thin red clay layer overlain by a thick one of black marl. These two layers are made up mainly from cheto-smectite and biogenic calcite. The black marl

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 ...

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 \(R\)
