Niobium oxide films deposited by reactive sputtering: Effect of oxygen flow rate
(2019-01-01)
Reactive sputtering is a versatile technique used to form compact films with excellent homogeneity. In addition, it allows easy control over deposition parameters such as gas flow rate that results in changes on composition ...
Plasma electrolytic oxidation up to four-steps performed on niobium and Nb-Ti alloys
(2022-05-25)
Plasma electrolytic oxidation (PEO) of up to four steps were performed on Niobium (Nb), and binary Niobium-Titanium alloys (Nbx-Ti, x = 50%, 90 wt.%), and the resulting oxidized surfaces were compared to their respective ...

Exploring the properties of niobium oxide films for electron transport layers in perovskite solar cells
(2019-01-01)
In this work, niobium oxide films were deposited by reactive magnetron sputtering under different oxygen flow rate and applied as electron transport layer in perovskite solar cells. It was found that the deposition made ...
Cytotoxicity and bioactivity of calcium silicate cements combined with niobium oxide in different cell lines
(2017-01-01)
The aim of this study was to evaluate the cytotoxicity and bioactivity of calcium silicate-based cements combined with niobium oxide (Nb2O5) micro and nanoparticles, comparing the response in different cell lines. This ...
