Rapid crystallization of LiFePO4 particles by facile emulsion-mediated solvothermal synthesis
(Powder Technology, 2012)
Lithium iron phosphate powders were obtained by solvothermal treatments of quaternary emulsions Triton X-100/cyclohexane/n-hexanol/water at low temperature (180 degrees C), with or without stirring. Such synthesis conditions ...

(Journal of Alloys and Compounds, 2010)
The influence of the heat treatment on the structural and magnetic properties of the nanoparticle La0.7Ca0.3MnO3 compound has been studied. The starting single-phase sample was prepared by the glycine nitrate method without ...
Room temperature ferromagnetism in Cu2+ doped TiO2 nanocrystals: The impact of their size, shape and dopant concentration
(Elsevier, 2016)
Cu2+ doped TiO2 nanocrystals were synthesized using dispersions of titania nanotubes in the presence of Cu2+ ions as a precursors. The morphologies of nanotubular titania precursors and resulted Cu2+ doped TiO2 nanocrystals ...
Combustion synthesis as a novel approach in preparation of polycrystalline Y2Cu2O5
(Journal of Alloys and Compounds, 2013)
Polycrystalline samples of Y2Cu2O5 were for the first time sintered from precursors obtained by two combustion routes - the glycine-nitrate method (sample S1) and a modified self-propagating high-temperature synthesis ...
Thermal stability of Ce1-xBixO2-delta (x=0.1-0.5) solid solution
(Journal of Alloys and Compounds, 2013)
Single phase solid solution Ce1-xBixO2-delta with the composition of x = 0.1-0.5 were successfully synthesized at room temperature using simple and fast Self Propagating Room Temperature procedure (SPRT). Thermal stability ...
Influence of MgO addition on the synthesis and electrical properties of sintered zinc-titanate ceramics
(Journal of Alloys and Compounds, 2009)
Starting mixtures of ZnO, TiO(2) and MgO (0, 1.25 and 2.5 wt.% MgO) powders were mechanically activated for 15 min in a planetary ball mill. The powders obtained were sintered non-isothermally to temperatures between 800 ...
Stereospecific ligands and their complexes. Part XV. Synthesis, characterization and cytotoxicity of novel platinum(IV) complexes with some esters of ethylenediamine-N,N -di-S,S-(2,2 -dibenzyl)acetic acid. Crystal structure of O,O -dipropyl-ethylenediamine-N,N -di-S,S-(2,2 -dibenzyl)acetate dihydrochloride
(Inorganica Chimica Acta, 2013)
The synthesis of ethylenediamine-N,N-di-S,S-(2,2-dibenzyl)acetic acid (H-2-S,S-eddba) and its ethyl-, propyl-, butyl-esters (R-2-S,S-eddba) are reported here. The esters were used for synthesis of the corresponding ...
