Visible-light active mesoporous, nanocrystalline N,S-doped and co-doped titania photocatalysts synthesized by non-hydrolytic sol-gel route
(Elsevier Sci Ltd, Oxford, 2016)
Visible-light active mesoporous N,S-doped and co-doped anatase TiO2 powders were synthesized by non-hydrolytic sol-gel route, starting from TiCl4 and Ti((OPr)-Pr-i)(4) dissolved in cyclohexane or dimethyl sulfoxide, later ...
Microstructure of new composite electrocatalyst and its anodic behavior for chlorine and oxygen evolution
(Elsevier Sci Ltd, Oxford, 2012)
The first layer of active coating made from a rutile-structured solid solution of ruthenium and titanium dioxides having an average crystal grain size of 30 nm was thermally deposited on an adequately prepared titanium ...
The dependence of the photocatalytic activity of TiO2/carbon nanotubes nanocomposites on the modification of the carbon nanotubes
(Elsevier Sci Ltd, Oxford, 2014)
Nanostructural TiO2/modified multi-wall carbon nanotubes photocatalysts were prepared by hydrolysis of Ti(iso-OC3H7)(4) providing chemical bonding of anatase TiO2 nanoparticles onto oxidized- or amino-functionalized ...
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 ...
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 ...
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 ...
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) ...
C-doped TiO2 nanotubes with pulsed laser deposited Bi2O3 films for photovoltaic application
(Ceramics International, 2022)
Anodization was used to obtain a nanotubular TiO2 photoanode on F-SnO2 glass. Subsequent annealing in the CH4 atmosphere promoted the C-doping and improved the crystallinity of the TiO2 nanotubes. The pulsed laser deposition ...
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 ...
