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 ...
The use of various dicarboxylic acids as a carbon source for the preparation of LiFePO4/C composite
(Elsevier Ltd., 2015)
Olivine-type LiFePO4 composite powders with carbon were synthesized by freeze drying and subsequent thermal annealing. The main purpose of the research is to explore how various dicarboxylic acids as carbon sources influence ...
The effect of the shape and size of the pores on the mechanical properties of porous HAP-based bioceramics
(Elsevier Sci Ltd, Oxford, 2011)
In this study, the influence of the shape and size of the pores on the mechanical properties of the obtained porous HAP-based bioceramics was investigated. The porous HAP-based bioceramics were obtained starting from ...
Microwave sintering of fine grained HAP and HAP/TCP bioceramics
(Elsevier Sci Ltd, Oxford, 2010)
The effect of microwave sintering conditions on the microstructure, phase composition and mechanical properties of materials based on hydroxyapatite (HAP) and tricalcium phosphate (TCP) was investigated. Fine grained ...
Preparation of TiO2/carbon nanotubes photocatalysts: The influence of the method of oxidation of the carbon nanotubes on the photocatalytic activity of the nanocomposites
(Elsevier Sci Ltd, Oxford, 2012)
A method for the preparation of efficient TiO2/multi-wall carbon nanotubes nanocomposite photocatalysts by precipitation of anatase TiO2 nanoparticles onto differently oxidized carbon nanotubes is presented. The precursor ...
Carboxylic acids and polyethylene glycol assisted synthesis of nanocrystalline nickel ferrites
(Elsevier Sci Ltd, Oxford, 2013)
Different synthesis methods for the preparation of nanocrystalline nickel ferrites are reported: the thermal decomposition of precursors, made of: (i) metal-nitrate salts with carboxylic acids (citric, malonic and tartaric), ...
Crystallization behavior and sintering of cordierite synthesized by an aqueous sol-gel route
(Elsevier Sci Ltd, Oxford, 2012)
The purpose of the research was to investigate crystallization behavior and sintering of cordierite synthesized by a low-price aqueous sol gel route starting from silicic acid and magnesium and aluminum salts. Viscous ...
Physical-mechanical and microstructural properties of alkali-activated fly ash-blast furnace slag blends
(Elsevier Sci Ltd, Oxford, 2015)
This paper investigated physical mechanical and microstructural properties of alkali-activated binders based on blends of fly ash (FA) and blast furnace slag (BFS). FA BFS blends were alkali-activated with sodium silicate ...
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 ...
Substrate preheating and structural properties of power plasma sprayed hydroxyapatite coatings
(Elsevier Sci Ltd, Oxford, 2016)
The aim of the present study was to investigate the influence of substrate preheating on the structural properties of hydroxyapatite coatings (HACs) deposited by using the high power (52 kW) laminar plasma jet. The deposition ...
