متن کاملMicroanalysis of Niobium in Iron Meteorites
Introduction: Niobium and tantalum are generally regarded to be lithophile incompatible elements occurring in chondritic relative proportions in planetary materials [1]. Precise Nb/Ta data have indicated that Nb may be depleted in the Earth's mantle [2, 3] which may be evidence for sequestering in an eclogite reservoir [2], or for its removal into the core [3, 4]. Metal-silicate partitioning ex...

متن کاملThrough-Hole, Self-Ordered Nanoporous Oxide Layers on Titanium, Niobium and Titanium–Niobium Alloys in Aqueous and Organic Nitrate Electrolytes
In the past decades, a variety of self-aligned functional oxides have successfully been grown on a wide range of metals using electrochemical, self-organizing anodization. The earliest reports on highly ordered oxide structures included porous aluminum oxide layers grown by optimized anodization of Al in oxalic acid. These nanoporous oxides found a considerable number of direct applications, su...
متن کاملElectron Pairing in Ferroelectric Niobium and Niobium Alloy Clusters
Cryogenic molecular beam experiments show that the ferroelectric dipole moments of small niobium clusters with an even number of valence electrons n are typically greater than those with odd n. This is verified in alloy clusters NbNXM where X = Al, Au, O, Mn, Fe, and Co; N ≤ 100;M ≤ 3. Like in superconducting alloys, Mn doping quenches the effect while Al and Au enhance it, suggesting a relatio...
