Phase evolution in Ce-doped yttrium-aluminum-based particles derived from aerosol
(Elsevier Sci Ltd, Oxford, 2007)
The common nitrates precursor solution leading to the Y3Al5O12:Ce3+ (YAG:Ce) composition with 2 at.% of cerium, is ultrasonically atomised and introduced into the tubular flow reactor at 320 degrees C. Having in mind that ...
Evolution of the microstructure of disperse ZnO powders obtained by the freeze-drying method
(Elsevier Science Sa, Lausanne, 2004)
Freeze-drying, as a cryochemical powder processing method is applied in the synthesis of ZnO submicrometer to narrosized powders. The process involves rapid freezing of the sprayed precursor solution, drying under vacuum ...
Nature of structural changes in LSM-YSZ nanocomposite material during thermal treatments
(Elsevier Science Sa, Lausanne, 2004)
Nanocomposite powders in the system (La1-xSx)(a)MnO3-YSZ((1-y)) [LSM-YSZ], as an attractive cathode material for high operating solid oxide fuel cell (SOFC), were obtained through ultrasonic spray pyrolysis (1.7 MHz) method. ...
Tailoring of morphology and orientation of LaNiO3 films from polymeric precursors
(Elsevier Sci Ltd, Oxford, 2007)
The aim of this work was to prepare lanthanum nickel oxide (LaNiO3, LNO) thin films of different morphology and orientation. The precursor solutions were prepared by a chemical method from citric salts of lanthanum and ...
The nature of structural changes in nanocrystalline ZnO powders under linear heating conditions
(Elsevier Sci Ltd, Oxford, 2004)
The nature of exothermal and irreversible structural changes observed during linear heating of nanocrystalline ZnO powders was investigated using differential scanning calorimetry, X ray, SEM and TEM analysis. Nanocrystalline ...
Nanostructured Fe2O3/TiO2 thick films
(Programme and Book of Abstracts of The Second Conference of The Serbian Ceramic Society, 2013)
Thick films of nanostructured pure TiO2, -Fe2O3, Fe2O3/TiO2 (ratio 2:3 and 3:2) and a hetero-junction in the form of a TiO2 layer over a Fe2O3 layer have been fabricated by screen printing technology on a glass substrate. ...
Hydrothermal treatment of nanoanatase with alkali and alkaline earth hydroxides
(Institute for Multidisciplinary Research, University of Belgrade, 2013)
Nanoanatase powder was hydrothermally treated with LiOH, NaOH, KOH or
Ca(OH)2 at T = 120 ºC for 8 h. In all cases, the molar TiO2 : hydroxide ratio was
identical. The obtained samples were washed with distilled water, ...
Photocatalytic degradation of textile dye with hydrothermally modified nanoanatase
(Institut za multidisciplinarna istraživanja, Belgrade, Serbia, 2015)
The environmental friendly materials based on titanium oxides are often chosen
for the industrial application due to their extraordinary characteristics (biological
and chemical stability, good photocatalitic activity, ...
The d-wave in fish and the state of light adaptation
(General Physiology and Biophysics, 2007)
Comparative electroretinographic studies of the d-wave evoked with long duration photo stimuli in dark- and light-adapted fish species (three marine and three freshwater) were performed. At the end of prolonged photo-stimulation ...
Hydro-evaporation and hydrothermal synthesis of BiFeO3
