Plasma resonance in TiO, VO and NbO

Journal of Solid State Chemistry, 1970
Reflectance spectra of TiO, VO, and NbO have been recorded. All these oxides show reflectance minima due to plasma edges. The energy corresponding to the reflectance minimum in TiO varies with stoichiometry (in the homogeneity range) and this phenomenon has been related to the transport properties of these oxides.

Superconductivity in the TiO and NbO systems

Journal of Low Temperature Physics, 1972
This paper presents electrical resistivity and superconductivity studies for the B1 (NaCl) structure oxides of titanium, vanadium, and niobium. In samples of nominal composition TiO x , VO x , and NbO x ,x was varied from 0.8 to 1.2.

Amorphous NbO films prepared by reactive evaporation

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1990
Reactive evaporation technique was employed to produce amorphous NbO thin films directly. It was revealed that the sheet electrical resistance of the amorphous NbO films was much greater than that of the crystalline counterpart. The thermal stability of the amorphous NbO films was studied by in situ annealing, and the crystallization temperature of the

Incorporation of bifunctional aminopyridine into an NbO-type MOF for the markedly enhanced adsorption of CO2 and C2H2 over CH4

Inorganic Chemistry Frontiers, 2019
An NbO-type MOF based on an aminopyridine-heterobifunctionalized diisophthalate linker was synthesized, displaying markedly enhanced C2H2 and CO2 adsorption over CH4 compared to its parent compound.

Neutron radiation damage in NbO single crystals

Radiation Effects, 1977
Abstract The effect of neutron irradiation and subsequent recovery has been studied for NbO single crystals of a defective NaCl structure containing 25% vacancies of niobium and oxygen. A very large increase (about 1%) in the lattice constant is observed after irradiation of 1.5 × 1019 and 1 × 1020 nvt (> 1 MeV).

Azobenzene Decorated NbO-Type Metal-Organic Framework for High-Capacity Storage of Energy Gases.

Inorganic Chemistry, 2019
Herein, a microporous NbO-type framwork (FJI-H23) that showed outstanding surface area (3740.4 m2·g-1) was fabricated by utilizing an azobenzene-derived carboxylate ligand. As anticipated, FJI-H23 can store 2.35 wt % H2 at 77 K up to 1 bar.

The potassium niobyl cyclotetrasilicate K2(NbO)2Si4O12

Journal of Solid State Chemistry, 1992
Abstract The single-phase compound K2(NbO)2Si4O12 was prepared by solid-state reaction. It crystallizes in the tetragonal system, space group P4bm with a = 8.7404(8)A and c = 8.136(1)A, Z = 2. The structure was determined from 484 reflections collected with a Nonius CAD4 diffractometer with MoKα radiation.

NbO/Nb2O5 core–shells by thermal oxidation

Journal of the European Ceramic Society, 2013
Abstract Niobium oxides have been reported as an alternative to tantalum, and its oxide, for the production of capacitors, but these materials still require a further and exhaustive study. Understanding the dynamics of the oxidation process from NbO to Nb 2 O 5 is essential to explain and control the properties of a niobium oxide based capacitors ...
