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 ...
Influence of annealing temperature on structural, optical and photocatalytic properties of TiO2-CeO2 nanopowders
(Elsevier Sci Ltd, Oxford, 2019)
TiO2-CeO2 nanopowders were synthesised by a ball-milling process and then annealed at temperatures from 500 degrees to 800 degrees C. X-ray diffraction and diffuse reflectance spectra were used in combination with temperature ...
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 ...
Gamma irradiation of graphene quantum dots with ethylenediamine: Antioxidant for ion sensing
(Elsevier, 2020)
Due to the low consumption of chemicals, the absence of toxic residual side products, the procedure simplicity and time-saving aspects, gamma irradiation offers advantages over the classical chemical protocols. We successfully ...
Preparation and characterization of clay-based porous ceramics with boric acid as additive
(Elsevier Sci Ltd, Oxford, 2014)
Intention of this work was to obtain porous silicon dioxide ceramics by using boric acid as an inexpensive additive at low forming pressure and low sintering temperature. Starting raw material, smectite clay from surface ...
Efficient photocatalytic hydrogen production over titanate/titania nanostructures modified with nickel
(Elsevier, 2019)
Nickel-modified titanate/TiO2 catalysts were prepared by deposition of nickel ions onto hydrothermally prepared titanate supports, followed by hydrogen temperature-programmed reduction. Two different nickel precursors ...
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 ...
Semiconducting cobalt oxide nanocatalyst obtained through an eco-friendly thermal decomposition
(Elsevier, 2023)
The combination of an intense absorption of visible light and p-type semiconducting nature makes spinel cobalt oxide (Co3O4) a very attractive material for various optoelectronic applications. However, the traditional ...
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 ...
