The oxidation of niobium and niobium/copper alloys.

, 1971
The oxidation of niobium and dilute niobium/copper alloys has been studied at 76 mm of oxygen in the temperature range 548-749°C, and at 0.76-760 mm of oxygen at 690°C. It has been shown that additions of copper decreased the oxidation resistance of niobium and that the oxidation reaction obeyed the modified parabolic law before breakaway ...

Selective synthesis of phosphate mono-esters with an acidic modified niobium oxide catalyst

Tetrahedron Green Chem
The atom-efficient esterification of phosphoric acid was investigated for the selective synthesis of phosphate mono-esters using an acid treated niobium oxide catalyst, avoiding the use of amines as is common in literature.

Polar Wurtzite NbAlN: A Transition‐Metal Nitride Alloy for Polarization‐Engineered GaN Heterostructures

Advanced Materials, EarlyView.
A novel polar wurtzite alloy, NbAlN, is demonstrated as a transition‐metal‐containing polar barrier for GaN heterostructures. Nb atoms form coherent nanoscale enrichment within the wurtzite lattice without disrupting metal polarity. This study demonstrates that transition metals can be integrated into polar nitrides to enable polarization‐related ...
