Highly ordered macroporous gamma-alumina prepared by a modified sol-gel method with a PMMA microsphere template for enhanced Pb2+, Ni2+ and Cd2+ removal
(Elsevier Sci Ltd, Oxford, 2017)
The adsorption performance of three-dimensionally ordered macroporous (3DOM) gamma-alumina was investigated for enhanced Pb2+, Ni2+ and Cd2+ removal. The synthesis was based on a modified sol-gel method using a colloidal ...
The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
(Elsevier Sci Ltd, Oxford, 2019)
Magnesium aluminate, MgAl2O4 and other alumina-based spinels are ceramics with high hardness, high melting point and mechanical strenght. Spinels can also be used as dielectrics in microwave applications. The goal of this ...
Re-formation of metastable epsilon-Fe2O3 in post-annealing of Fe2O3/SiO2 nanostructure: Synthesis, computational particle shape analysis in micrographs and magnetic properties
(Ceramics International, 2017)
Several Fe2O3/SiO2 nanostructures were synthesized by the combination of the microemulsion and a sol-gel methods. Based on X-ray powder diffraction (XRD) and magnetic measurements (giant coercivity similar to 2.13 T) we ...
Tuning of BiFeO3 multiferroic properties by light doping with Nb
(Elsevier Sci Ltd, Oxford, 2018)
Bulk ceramic samples of BiFeO3 were light doped (up to 1%) with Nb5+ in the place of Fe3+ (B-site doping) and their multiferroic properties were investigated using XRD, SEM, polarization (PMTS) and magnetization (SQUID) ...
Bioactive glass-ceramics prepared by powder sintering and crystallization of polyphosphate glass containing strontium
(Elsevier Sci Ltd, Oxford, 2017)
Melt-quenching method was employed for obtaining a glass-ceramic with the following composition 42P(2)O(5). 40CaO.5SrO.10Na(2)O.3TiO(2) (mol%) glass. The crystallization and sintering behavior of glass have been studied ...
Mg/Cu co-substituted hydroxyapatite - Biocompatibility, mechanical properties and antimicrobial activity
(Elsevier Sci Ltd, Oxford, 2019)
The aim of this study was to improve the mechanical properties and to optimize antimicrobial activity of hydroxyapatite (HAP) by simultaneous doping with Mg and Cu ions in order to obtain material that would be able to ...
Dry-pressed anodized titania nanotube/CH3NH3PbI3 single crystal heterojunctions: The beneficial role of N doping
(Elsevier Sci Ltd, Oxford, 2019)
Highly ordered, anodically grown TiO2 nanotubes on titanium supports were annealed in ammonia atmosphere in order to incorporate nitrogen doping ( lt = 2 at.%) in the titanium oxide lattice. FESEM micrographs revealed ...
Change in structural, ferroelectric, and magnetic properties of bismuth ferrite induced by doping with gadolinium
(Elsevier Sci Ltd, Oxford, 2019)
Bismuth ferrite, BiFeO3, was doped with a wide range of concentrations (0-30%) of Gd in order to investigate structural, ferroelectric, and magnetic properties and their correlation. Powder samples of Bi1-xGdxFeO3 (x = ...
Optimized preparation of alumina based fillers for tuning composite properties
(Elsevier Sci Ltd, Oxford, 2018)
Alumina based particles were prepared from aluminium chloride hydroxide as starting material by sol-gel technique. One series of particles was doped with ferrous oxide. Both series of particles were calcinated at three ...
Influence of annealing treatment on magnetic properties of Fe2O3/SiO2 and formation of epsilon-Fe2O3 phase
(Ceramics International, 2017)
Magnetic properties of Fe2O3/SiO2 samples were studied after being produced by sol-gel synthesis and formation of epsilon-Fe2O3 polymorph. Samples were thermally treated, using different annealing temperatures and annealing ...
