Effect of niobium dopant on fatigue characteristics of BiFeO3 thin films grown on Pt electrodes
(Elsevier B.V. Sa, 2009-06-24)
Pure BiFeO3 (BFO) and Nb-doped (BFN) thin films were fabricated by the soft chemical method. The films were polycrystalline when deposited on Pt/Ti/SiO2/Si substrate and annealed at 500 degrees C for 2 h. X-ray diffraction ...
Broadband NIR emission in novel sol-gel Er3+-doped SiO 2-Nb2O5 glass ceramic planar waveguides for photonic applications
(2013-01-01)
This paper reports on the sol-gel preparation and structural and optical characterization of new Er3+-doped SiO2-Nb 2O5 nanocomposite planar waveguides. Erbium-doped (100-x)SiO2-xNb2O5 waveguides were deposited on ...
Influência da adição de nióbio sobre a usinabilidade de ferro fundido cinzento perlítico na operação de torneamento
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA PRODUÇÃOPrograma de Pós-Graduação em Engenharia de ProduçãoUFMG, 2021-03-12)
The attempt to reduce weight, by reducing the cross sections of components, linked to an increasing demand for greater thermal efficiency, requires more efforts in the development of gray cast iron. Therefore, metallurgical ...
Electrodeposition and characterization of Cu-Nb composite coatings
(ELSEVIER SCIENCE SA, 2010)
Copper coatings containing well-distributed Nb particles were obtained by co-electrodeposition in an acidic sulfate bath. Nb particle concentration in the bath was the most significant factor for the incorporation of Nb ...
