Composite membrane of niobium(V) oxide and cellulose acetate: Preparation and characterization
(Academic Press Inc Jnl-comp SubscriptionsSan Diego, 1997)
Recent Advances in Using Niobium Compounds as Catalysts in Organic Chemistry
(Bentham Science Publ Ltd, 2015-01-01)
Niobium is not found in nature in its free form, but usually in the form of oxides and usually with the tantalum element. The largest niobium reserves are in Brazil. The use of niobium compounds in organic synthesis has ...
The Growing Impact of Niobium in Organic Synthesis and Catalysis
(Aldrich Chemical Co Inc, 2012-01-01)
The growing interest in, and applications of, niobium compounds in organic synthesis and catalysis are surveyed, with a focus on their efficiency and versatility in several classical and broad organic reaction types. It ...
Preparation and characterization of niobium oxide coated cellulose fiber
(Academic Press Inc Jnl-comp SubscriptionsSan Diego, 1996)
Preparation and characterization of cellulose/hydrous niobium oxide hybrid
(Elsevier B.V., 2012-07-01)
A composite of cellulose extracted from bagasse with Nb2O5 center dot nH(2)O in three different proportions (16.67, 37.5 and 50.0 wt%) was prepared using the co-precipitation method. The materials were characterized by ...
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 ...
Adsorption of phosphoric acid on niobium oxide coated cellulose fiber: preparation, characterization and ion exchange property
(Sociedade Brasileira de Química, 2005)
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 ...
