Triethanolamine as an efficient cosolvent for biodiesel production by CaO-catalyzed sunflower oil ethanolysis: An optimization study
(Hemijska industrija, 2019)
Triethanolamine was applied as an efficient „green“ cosolvent for biodiesel production by CaO-catalyzed ethanolysis of sunflower oil. The reaction was conducted in a batch stirred reactor and optimized with respect to the ...
Structural and electrical properties of geopolymer materials based on different precursors (kaolin, bentonite and diatomite)
(Skopje : Institute of Chemistry, Faculty of Natural Sciences and Mathematics, Ss. Cyril & Methodius University, 2019)
Geopolymers (GP) were successfully synthesized from metabentonite (MB), metadiatomite (MD) and metakaolinite (MK). Characterization of their phase structure and microstructure was performed by XRD, FTIR, SEM/EDX methods. ...
Nanocomposite Zn2SnO4/SnO2 Thick films as a Humidity Sensing Material
(IEEE, 2019)
Nanocomposite Zn2SnO4/SnO2 powder was obtained by solid state synthesis from homogenized starting nanopowders of ZnO and SnO2 mixed in the 1:1 molar ratio, structurally and morphologically characterized using X-ray diffraction ...
A novel type of building material derived from the by-products of steel making industry
(Belgrade : Materials Research Society of Serbia, 2019)
Electric arc furnace slag (EAFS) and electric arc furnace dust (EAFD) are the waste materials generated during the iron and steel scrap remelting in electric arc furnace. EAFS is non-hazardous material which has found its ...
Structure, morphology and photocatalytic properties of CoxMg1-xFe2O4 (0<x<1) spinel ferrites obtained by sol-gel synthesis
(Belgrade : Materials Research Society of Serbia, 2019)
Nanocrystalline cobalt magnesium ferrites with varying cobalt and magnesium content (CoxMg1-xFe2O4, 0<x<1) were synthesized using the sol-gel self-combustion method with citric acid as fuel, followed by calcination at 700 ...

Valorization of walnut shell ash as a catalyst for biodiesel production
(Elsevier, 2020)
The catalytic activity of the walnut shell ash was investigated in the biodiesel production by the sunflower oil methanolysis. The catalyst was characterized by the TG-DTA, XRD, Hg porosimetry, N2 physisorption, SEM, and ...
Evolution of the microstructure of disperse ZnO powders obtained by the freeze-drying method
(Lausanne : Elsevier Science, 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 ...
Morphological and structural characterization of spinel MgAl2O4
(Belgrade : Serbian Ceramic Society, 2019)
Magnesium aluminate has spinel structure and very good mechanical, chemical, and thermal properties. Owing to these properties, it has a wide range of applications including refractory ceramics, optically transparent ceramic ...
