Niobium pentoxide as radiopacifying agent of calcium silicate-based material: evaluation of physicochemical and biological properties
(2015)
Objectives The physicochemical properties and the tissue reaction promoted by microparticulated or nanoparticulated niobium pentoxide (Nb2O5) added to calcium silicate-based cement (CS), compared to MTA-Angelus™, were ...
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 ...
Ni-Nb mixed oxides: One-pot synthesis and catalytic activity for oxidative dehydrogenation of ethane
(Elsevier Science, 2014-06-20)
Ni–Nb mixed oxides were prepared by two methods, conventional evaporation method and combustion synthesis. With the latter technique, the mixed oxide can be quickly prepared from an aqueous solution of metal precursors ...
Cobalt(II) Hematoporphyrin IX immobilized in a cellulose acetate niobium(V) oxide composite membrane: preparation and oxygen reduction study
(Sociedade Brasileira de Química, 1998)
Spectroscopic studies of SnO2 doped with Cr, Co or Nb
(2003-03-15)
SnO2 ceramics doped with different amounts of Co, Cr or Nb were investigated using visible and infrared spectroscopy at room temperature. Based on the observed d-d transitions the valence states of incorporated dopants ...
Zirconium phosphate dispersed on a cellulose fiber surface: Preparation, characterization, and selective adsorption of Li+, Na+, and K+ from aqueous solution

SnO 2 ceramics with low electrical resistivity obtained by microwave sintering
(2011-08-01)
The main aim of this study was to develop dense and conducting SnO 2 ceramics without precipitated phases on the grain boundaries, which was verified using field emission scanning microscopy (FE-SEM) coupled with an ...
Nb-containing hematites Fe2-xNbxO3: The role of Nb5+ on the reactivity in presence of the H2O2 or ultraviolet light
(Elsevier B.V., 2009-03-31)
A series of Nb-containing hematites, Fe-2-xNbxO3 (%Nb = 0.00, 1.49, 5.00 and 9.24) was prepared using the conventional co-precipitation method. Mossbauer and temperature-programmed reduction (TPR) measurements suggested ...
Niobium Effects on the Recrystallization Behavior on a Full Austenitic 15Cr-15Ni Stainless Steel Investigated Using Adaptive Neural Networks (ANN)
(AMER SCIENTIFIC PUBLISHERSVALENCIA, 2012)
A new series of austenitic stainless steels-Nb stabilized, without Mo additions, non-susceptible to delta ferrite formation and devoid of intemetallic phases (sigma and chi), without deformation induced martensite is being ...
