The synthesis of single phase WC nanoparticles/C composite by solid state reaction involving nitrogen-rich carbonized polyaniline
(Elsevier Sci Ltd, Oxford, 2013)
Single phase tungsten carbide nanoparticles (WC-NPs), (mean particle diameter 5.4 nm), distributed over carbonized polyaniline (C-PANT) nanotubes/nanosheets were synthesized by a solid state reaction between WO3 and ...
Microstructure of LaNiO3 thin films obtained by the spin-on technique from citrate precursors
(Elsevier Sci Ltd, Oxford, 2008)
The morphology of perovskite LaNiO3 (LNO) thin films is a very important feature considering the fact that they could be used as an electrode material in ferroelectric devices. In this work, LNO films were prepared from ...
The NaxMnO2 materials prepared by a glycine-nitrate method as advanced cathode materials for aqueous sodium-ion rechargeable batteries
(Elsevier, 2021)
Cathodic material for sodium-ion rechargeable batteries based on NaxMnO2 were synthesized by glycine nitrate method and subsequent annealing at high temperatures. Different crystal structures with different morphologies ...
Biomimetic synthesis and properties of cellular SiC
(Elsevier Sci Ltd, Oxford, 2014)
Biomorphous beta-SiC ceramics were produced from several species of wood such as ash, wild cherry, black alder, Persian walnut, sessile oak and European hornbeam. The wood was pyrolysed, impregnated with tetraethyl ...
Effect of boric acid on the porosity of clay and diatomite monoliths
(Elsevier Sci Ltd, Oxford, 2016)
Porous silica ceramics were obtained at low forming pressure (40-80 MPa) and low sintering temperature (850-1300 degrees C) for 4 h in air. Boric acid was used as a low-cost additive, in the amount of 2 wt%. Relatively ...
Porous ceramic monoliths based on diatomite
(Elsevier Sci Ltd, Oxford, 2015)
Porous silica ceramics were obtained at low forming pressure and low sintering temperature by using diatomaceous earth as a silica source and boric acid as an inexpensive additive. The starting raw material, diatomite from ...
A study of the structural and morphological properties of Ni-ferrite, Zn-ferrite and Ni-Zn-ferrites functionalized with starch
(Elsevier Sci Ltd, Oxford, 2018)
Zinc-ferrite, nickel-ferrite and mixed nickel-zinc ferrites were successfully synthesized via the thermal decomposition method from acetylacetonate complexes. To control the particle size and enhance dispersibility in an ...
Morphology investigation of mechanically activated ZnO-SnO2 system
(Elsevier Sci Ltd, Oxford, 2008)
Powder mixtures of zinc oxide and tin oxide in the molar ratio, ZnO:SnO2 = 2:1, were mechanically activated in a planetary ball mill in the time intervals of 0-160 min. The adsorption-desorption isotherms, specific surface ...
Microwave assisted hydrothermal synthesis of (Fe,Co)(3)O-4 nanoparticles in the presence of surfactants and effects of Co/Fe ratio on microstructure and magnetism
(Elsevier Sci Ltd, Oxford, 2018)
Microstructure and magnetic properties of nanoparticles can be tailored by optimising the synthesis procedure and changing chemical composition. In this study, a two-step procedure, i.e., coprecipitation in the presence ...
