Structural, electrical and magnetic properties of nickel manganite obtained by a complex polymerization method
(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 ...
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 ...
Physical-mechanical and microstructural properties of alkali-activated fly ash-blast furnace slag blends
(Elsevier Sci Ltd, Oxford, 2015)
This paper investigated physical mechanical and microstructural properties of alkali-activated binders based on blends of fly ash (FA) and blast furnace slag (BFS). FA BFS blends were alkali-activated with sodium silicate ...
Lead immobilization by geopolymers based on mechanically activated fly ash
(Elsevier Sci Ltd, Oxford, 2014)
In this paper, the effectiveness of geopolymers based on initial and mechanically activated fly ash in immobilization of lead was investigated. Fly ash (FA) was firstly mechanically and then alkali activated at room ...
Lead-free BaBi4Ti4O15 ceramics: Effect of synthesis methods on phase formation and electrical properties
(Elsevier Sci Ltd, Oxford, 2015)
The processing of ferroelectric BaBi4Ti4O15 (BBT) ceramics from powders prepared by conventional solid state reaction (SSR) and mechanochemical activation (MA) has been investigated. It was shown that MA synthesis reduces ...
Dielectric and ferroelectric properties of BST ceramics obtained by a hydrothermally assisted complex polymerization method
(Elsevier Sci Ltd, Oxford, 2015)
Ba0.8Sr0.2TiO3 (BST) powder, obtained by a hydrothermal treatment of precursor solution previously prepared by a complex polymerization method (HT-CPM), was uniaxially pressed and sintered at 1280 degrees C for 1-32 h. The ...
Antiferromagnetism and heat capacity of NaCo2-xCuxO4 ceramics
(Elsevier Sci Ltd, Oxford, 2017)
Polycrystalline samples of NaCo2-xCuxO4 (x=0, 0.01, 0.03 and 0.05) were synthesized in two different ways: 1) by a mechanochemically assisted solid-state reaction method (MASSR) and 2) by a citric acid complex method (CAC). ...
Magneto-electric properties of xNi(0.7)Zn(0.3)Fe(2)O(4) - (1-x)BaTiO3 multiferroic composites
(Elsevier Sci Ltd, Oxford, 2018)
Di-phase ceramic composites, with general formula xNi(0.7)Zn(0.3)Fe(2)O(4) - (1-x)BaTiO3(x = 0.9, 0.7, 0.5, 0.3, 0.1), were prepared by a mixing method. X-ray analysis, for powder and ceramics, indicated the formation of ...
