CdS quantum dots sensitized TiO2 nanotubes by matrix assisted pulsed laser evaporation method
(Elsevier Sci Ltd, Oxford, 2016)
Within this study a matrix assisted pulsed laser evaporation technique was employed for deposition of CdS quantum dots onto TiO2 nanotubes. The number of laser pulses and laser fluence were varied to control the amount of ...
Influence of different pore-forming agents on wollastonite microstructures and adsorption capacities
(Elsevier Sci Ltd, Oxford, 2017)
In this study, porous macro- and micro-cellular wollastonite-based ceramics was synthesized. A ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as a starting material. After 20 min of ...
Barium titanate screen-printed thick films
(Elsevier Sci Ltd, Oxford, 2002)
Barium titanate (BT) thick films were prepared from mechanically activated powders based on BaCO3 and TiO2. After homogenization and milling in a high-energy vibro mill, the powders were calcined at 700 degreesC for 2 h ...
Optimization of bentonite clay mechano-chemical activation using artificial neural network modeling
(Elsevier Sci Ltd, Oxford, 2017)
The properties of seven montmorillonite-rich bentonites of different geological origin were investigated prior and subsequent to mechano-chemical processing in an ultra-centrifugal mill. The objective of the experiment was ...
Effect of consolidation parameters on structural, microstructural and electrical properties of magnesium titanate ceramics
(Elsevier Sci Ltd, Oxford, 2016)
The aim of this study is to explore the influence of the processing route on the structural and physical properties of bulk MgTiO3 ceramics. Commercially available MgO and TiO2 powders were mechanically activated in a ...
Structural investigation of mechanically activated nanocrystalline BaTiO3 powders
(Elsevier Sci Ltd, Oxford, 2011)
In this article, in order to obtain tetragonal nanocrystalline BaTiO3, structural investigations of mechanically activated BaTiO3 powder have been performed. A mercury porosimetry analysis and scanning electron microscopy ...
Isothermal sintering of barium-zinc-titanate ceramics
(Elsevier Sci Ltd, Oxford, 2011)
Mixtures of BaCO3-ZnO-TiO2 were mechanically activated using high-energy planetary ball mill during 20, 40 and 80 min. As the time of mechanical activation increased, the decrease in particle size was observed. The effect ...
Effects of mechanical activation and two-step sintering on the structure and electrical properties of cordierite-based ceramics
(Elsevier Sci Ltd, Oxford, 2016)
The mechanical activation can help reduce production costs and modify cordierite-based materials. In this study, the structure and electrical properties of the mechanically activated MgO-Al2O3-SiO2 system have been analyzed. ...
Morphology investigation of mechanically activated ZnO-SnO2 system
(Elsevier Sci Ltd, Oxford, 2008)
Powder mixtures of zinc oxide and tin oxide in the molar ratio, ZnO:SnO2 = 2: 1, were mechanically activated in a planetary ball mill in the time intervals of 0-160 min. The adsorption-desorption isotherms, specific surface ...
Efficient photocatalytic hydrogen production over titanate/titania nanostructures modified with nickel
(Elsevier Sci Ltd, Oxford, 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 ...
