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 ...
Comparative study of CeO2 nanopowders obtained by the hydrothermal method from various precursors
(Elsevier Sci Ltd, Oxford, 2015)
The effects of common precursors used in the synthesis of CeO2 nanopowders were investigated, and the structural and spectral properties of the resulting products were compared. Two cerium (III) salts, i.e., Ce(NO3)(3)center ...
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 ...
Sr,Mg co-doping of calcium hydroxyapatite: Hydrothermal synthesis, processing, characterization and possible application as dentin substitutes
(Ceramics International, 2022)
The aim of this study was to investigate the influence of binary Sr, Mg ion-doping compared to the single-ion doping effects on the phase composition and morphology of hydrothermally obtained calcium hydroxyapatite (HAP) ...
Mechanical properties and thermal shock resistance of anorthite ceramics obtained by slip casting
(Elsevier Ltd., 2024)
Anorthite ceramics (CaAl2Si2O8) was obtained by slip casting of water suspension of kaolin (Al2O3·2SiO2·2H2O) and CaCO3 as a source of CaO. A relative density of 87 % of the theoretical density was achieved after a 3-h-long ...
alpha-Tricalcium phosphate/fluorapatite based composite cements: Synthesis, mechanical properties, and biocompatibility
(Elsevier Sci Ltd, Oxford, 2020)
Composite cements based on alpha-tricalcium phosphate (alpha-TCP) and nanostructured fluorapatite (FAp), alpha-TCP/FAp, appropriate for dental usage as root canal filling material, have been prepared with the improved ...
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 ...
Effect of YAG content on creep resistance and mechanical properties of Al2O3-YAG composite
(Elsevier Sci Ltd, Oxford, 2020)
Comprehensive study on effect of YAG amount on densification, creep resistance and room-temperature mechanical properties of Al2O3-YAG composite pressureless sintered at 1600 degrees C was conducted. The main goal was to ...
Structural and morphological characterization of iron-doped sol-gel derived mullite powders
(Elsevier Sci Ltd, Oxford, 2020)
The structural and morphological properties of iron-doped mullite powders are the subject of the present study. The powders of undoped and iron-doped mullite in the composition range of 3-15 wt% Fe2O3 were synthesized by ...
Synthesis of pure and La-doped anatase nanopowders by sol-gel and hydrothermal methods and their efficiency in photocatalytic degradation of alprazolam
(Elsevier Ltd., 2014)
Pure and La3+ doped titanium dioxide (TiO2) nanopowders were obtained by sol gel and hydrothermal methods. A precursor was titanium tetrachloride and concentrations of dopants were 0.5 and 1.0 mol%. Procedures of both ...
