Zirconium dioxide nanopowders with incorporated Si4+ions asefficient photocatalyst for degradation of trichlorophenol usingsimulated solar light
(Elsevier, 2016)
We present a hydrothermal method for synthesis of zirconia nanopowders: pure and with incorporatedSi4+ions. Zirconyl chloride and tetraethyl orthosilicate were used as precursors. As prepared powderswere annealed at 600◦C ...
Effect of PEO molecular weight on sunlight induced photocatalytic activity of ZnO/PEO composites
(Elsevier, 2016)
ZnO spheroidal nanoparticles, synthesized by microwave processing, were used for preparation of composites with polyethylene oxide (PEO). The phase purity and crystal structure of the composites were investigated by X-ray ...
Alkali-Aggregate Reactions in Concrete
(Atlantis Press, 2016)
In most concretes, aggregates are more or less chemically inert. However, some aggregates react with the alkali hydroxides in concrete, causing expansion and cracking over a period of many years. This alkali-aggregate ...
Structural and magnetic properties of mechanochemically synthesized LaFe1-xCrxO3 (x = 0.5 and 0.75)
(Belgrade : Materials Research Society of Serbia, 2016)
Perovskite oxides with the composition LaFe1-xCrxO3 (x = 0.5 and 0.75) have been studied. The samples have been prepared using the mechanochemical treatment. A mixture of crystalline La(OH)3, Fe2O3 and Cr2O3 powders in ...
Automatic devices for electrochemical water treatment with cooling of electrolyte
(Association of the Chemical Engineers of Serbia, 2016)
The most common disinfectants for water treatment are based on chlorine and its compounds. Practically, water treatments with chlorine compounds have no alternative, since they provide, in comparison to other effective ...
