Co-doping as a strategy for tailoring the electrolyte properties of BaCe0.9Y0.1O3-delta
(Elsevier Sci Ltd, Oxford, 2019)
The properties of single-doped BaCe0.9Y0.1O3-delta and materials co-doped with 5 mol % of different cations (In3+, Zr4+ and Nb5+) with the general formula BaCe0.85Y0.1M0.05O3-delta were compared to examine the influence ...
Improvement of barium titanate properties induced by attrition milling
(Elsevier Sci Ltd, Oxford, 2012)
Barium titanate powder was prepared by soft chemical process from polymeric precursors (modified Pechini process). The synthesized barium titanate (BT) powder was nanosized and the factor of agglomeration (F-agg) pointed ...

(Elsevier Sci Ltd, Oxford, 2014)
Structural, electrical and magnetic properties of nickel manganite ceramics obtained by sintering fine powders prepared by a complex polymerization method are given in this work. The phase composition of the synthesized ...
Enhanced stability in CO2 of Ta doped BaCe0.9Y0.1O3-delta electrolyte for intermediate temperature SOFCs
(Elsevier Sci Ltd, Oxford, 2013)
The influence of Ta concentration on the stability of BaCe(0.9-)xTa(x)Y(0.1)O(3-delta) (where x=0.01, 0.03 and 0.05) powders and sintered samples in CO2, their microstructure and electrical properties were investigated. ...
Ex-situ sensitization of ordered TiO2 nanotubes with CdS quantum dots
(Elsevier Sci Ltd, Oxford, 2015)
Ordered titania nanotubes (pore diameter approximate to 90 nm and wall thickness approximate to 10 nm) were obtained by the anodization technique and used for the ex-situ deposition of cadmium sulfide quantum dots (CdS ...
Nanostructured Fe2O3/TiO2 thick films: Analysis of structural and electronic properties
(Elsevier Sci Ltd, Oxford, 2015)
Thick films using starting nanopowders of TiO2 (anatase 99.7%) and alpha-Fe2O3 (hematite) mixed in the weight ratios 60:40 and 40:60 for thick film paste were fabricated by screen printing technology on an alumina substrate. ...
Multiferroic (NiZn) Fe2O4-BaTiO3 composites prepared from nanopowders by auto-combustion method
(Elsevier Sci Ltd, Oxford, 2015)
Nickel zinc ferrite (NZF) and barium titanate (BT) were prepared by auto-combustion synthesis as an effective, simple and rapid method. Multiferroic composites with the general formula yNi(1-x)Zn(x)Fe(2)O(4)-(1-y)BT (x=0.3, ...

(Elsevier Sci Ltd, Oxford, 2016)
Visible-light active mesoporous N,S-doped and co-doped anatase TiO2 powders were synthesized by non-hydrolytic sol-gel route, starting from TiCl4 and Ti((OPr)-Pr-i)(4) dissolved in cyclohexane or dimethyl sulfoxide, later ...
Donor-acceptor joint effect in barium titanate systems
(Elsevier Sci Ltd, Oxford, 2015)
Modified Pechini process was used to prepare nanopowders of barium titanate (BT) co-doped with different concentrations of niobium and manganese. Influence of dopants on the grain growth inhibition and microstructure ...
Nanoindentation study of nickel manganite ceramics obtained by a complex polymerization method
(Elsevier Sci Ltd, Oxford, 2016)
The chemical synthesis of nickel manganite powder was performed by a complex polymerization method (CPM). The obtained fine nanoscaled powders were uniaxially pressed and sintered at different temperatures: 1000-1200 degrees ...
