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 ...
Absorption boost of TiO2 nanotubes by doping with N and sensitization with CdS quantum dots
(Elsevier Sci Ltd, Oxford, 2017)
A process of obtaining N-doped TiO2 nanotubes sensitized by CdS nanoparticles is presented, including detailed characterizations performed along the synthesis. Transparent TiO2 films consisting of nanotubes, 2.5 mu m long ...
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 ...
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) ...
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 ...
Nanoindentation study of nickel manganite ceramics obtained by a complex polymerization method
(Elsevier Sci Ltd, Oxford, 2016)
The chemical synthesis of nickel manganite powder was performed by a complex polymerization method (CPM). The obtained fine nanoscaled powders were uniaxially pressed and sintered at different temperatures: 1000-1200 degrees ...
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 ...
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 ...
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 ...
