Prebiotici i mehanizam njihovog dejstva
(Beograd: Udruženje mikrobioologa Srbije, 2012)
Prebiotici su nesvarljivi sastojci hrane, koji u nepromenjenom obliku dospevaju u kolon, selektivno stimulišući rast i metaboličku aktivnost jedne ili ograničenog broja bakterijskih vrsta i na taj način poboljšavaju zdravlje ...
The effect of Ni content on passivation of copper anodes with non-standard chemical composition
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
In this paper are presented the results of the first appearance of full pasivation during the treatment of the waste sulphuric-acid solution generated in the conventional copper electrorefining process. The copper anodes ...
Mechanochemical Preparation of CaO·ZnO – catalyst for Fatty Acids Methyl Esters Synthesis
(Belgrade : Serbian Ceramic Society, 2012)
One of the catalysts that show excellent activity in the methanolysis of vegetable oil under moderate reaction conditions is the mixture of CaO and ZnO oxides. In this study CaO•ZnO catalyst was synthesized by mechanochemical ...
