Shape and aspect ratio analysis of anisotropic magnetic nanochains based on TEM micrographs
(Ceramics International, 2018)
Due to advances in electron microscopy and to the development of novel nanoparticle structures with different morphologies and the dependence of physical properties on the nanoparticle morphology, there is a need for a ...
Efficient photocatalytic hydrogen production over titanate/titania nanostructures modified with nickel
(Ceramics International, 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 new endodontic mixture based on calcium aluminate cement obtained by hydrothermal synthesis
(Ceramics International, 2019)
The synthesis of a new endodontic mixture based on calcium aluminate cement is reported. Physico-chemical and mechanical properties of the mixture were investigated before and after various hydration periods. Phase analysis ...
Niobium and zinc doped titanium-tin-oxide solid-solution ceramics: Synthesis, structure and electrical characterization
(Ceramics International, 2018)
This paper describes the processing, microstructure, optical and electrical properties of the nanocrystalline (NC) niobium and zinc doped titanium-tin-oxide (TTO:NZ) based ceramics. Variety of techniques was employed (X-ray ...
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
(Ceramics International, 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 ...
Tracking of the electronic re-ordering in Fe3O4/OA nanoparticles using magnetometry
(Ceramics International, 2019)
We performed structural and magnetic investigation of Fe3O4/OA nanoparticles prepared by solvothermal method. Based on XRD, TEM and FTIR examination, investigated sample contained monodisperse, 5 nm-sized spherical magnetite ...
Green and facile microwave assisted synthesis of (metal-free) N-doped carbon quantum dots for catalytic applications
(Ceramics International, 2019)
Industrialization today leads to a significant increase in the environmental pollution, with number of phenols, pesticides, paints, solvents and other organic pollutants with potentially carcinogenic effect in natural ...
A comparative study of photocatalytically active nanocrystalline tetragonal zyrcon-type and monoclinic scheelite-type bismuth vanadate
(Ceramics International, 2018)
Monoclinic scheelite-type BiVO4 is currently considered as one of the most promising non-titania photocatalysts, wheras tetragonal zircon-type BiVO4 is still poorly understood. Herein, a new and simple synthetic approach ...
Synthesis, characterization and sintering of Gd2Hf2O7 powders synthesized by solid state displacement reaction at low temperature
(Ceramics International, 2018)
Pyrochlore compound (Gd2Hf2O7) powder was prepared by reacting gadolinium nitrate and hafnium chloride with NaOH during solid state displacement reaction at low temperature (SSDR). The SSDR process at room temperature ...
Improved coloristic properties and high NIR reflectance of environment-friendly yellow pigments based on bismuth vanadate
(Ceramics International, 2018)
Herein, fine powders of yellow pigments based on BiVO4 were successfully prepared in two crystalline forms, tetragonal zircon-structured and monoclinic scheelite-structured, through a ethylene glycol-assisted method subjected ...
