The influence of fluorine doping on the structural and electrical properties of the LiFePO4 powder
Low intrinsic electronic conductivity is the main disadvantage of LiFePO4 when used as a cathode material in lithium ion batteries. The paper offers experimental proofs of the theoretical prediction that fluorine doping ...

Rietveld analysis of XRD patterns of mechanically activated Fe:BaTiO3 powder mixtures sintered at 1200°C
Analytical modeling of activation procedure applied in α-alumina thermo-mechanical synthesis
The impact of the mechanical processing parameters on the alumina grain-size distribution affiliated characteristics and on the γ to α phase transformation rate was investigated. The moderation in the alumina samples ...
The use of various dicarboxylic acids as a carbon source for the preparation of LiFePO4/C composite
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 ...
Dry-pressed anodized titania nanotube/CH3NH3PbI3 single crystal heterojunctions: The beneficial role of N doping
Highly ordered, anodically grown TiO 2 nanotubes on titanium supports were annealed in ammonia atmosphere in order to incorporate nitrogen doping (≤2 at.%) in the titanium oxide lattice. FESEM micrographs revealed nanotubes ...
Dielectric characteristics of donor-acceptor modified BaTiO3 ceramics
Sm/Mn codoped BaTiO3 ceramics were investigated for their microstructure and dielectric characteristics. The powders were prepared by the conventional solid state procedure. The concentration of Sm2O3 as a donor dopant has ...
Optimization of bentonite clay mechano-chemical activation using artificial neural network modeling
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 ...
Fractal approach to BaTiO3-ceramics micro-impedances
A new approach, based on fractal geometry and correlation between microstructure-nanostructure and rare-earth properties and other additives doped BaTiO3-ceramics and electronics properties, is applied. The grain contacts ...
Influence of different pore-forming agents on wollastonite microstructures and adsorption capacities
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 ...
Influence of ageing of milled clay and its composite with TiO2on the heavy metal adsorption characteristics
The aim of the present study was to investigate the effect of ageing of mechanochemically synthesized clay and its TiO2composite on the simultaneous removal of Pb(II), Cd(II), Cu(II) and Zn(II) ions from acidic aqueous ...
