Removal of methyl tertiary butyl ether from wastewaters using photolytic, photocatalytic and microbiological degradation processes
(Elsevier Science Bv, Amsterdam, 2007)
Contamination of groundwater by methyl tertiary butyl ether (MTBE), that is detected in wastewater of petrochemical industry, is an increasing problem to water supply companies. The subjects of this research were the methods ...
Mechanochemical synthesis of gamma-Bi2O3
(Amsterdam : Elsevier, 2004)
A series of gamma-Bi2O3 phases doped with Zn, Si, Pb and Fe was prepared by mechanochemical treatment of corresponding oxide mixtures with a nominal composition 6Bi(2)O(3) (.) MOx (MOx = ZnO, SiO2, PbO) and 12Bi(2)O(3) (.) ...
Comparative analysis of laboratory accreditation in Bulgaria, Lithuania, Slovakia and Serbia and Montenegro
(Springer-Verlag, 2005)
The development of an internationally recognized laboratory accreditation process, accompanied by a mutual recognition agreement (MRA), is an issue of great interest in Central and Eastern European countries. This paper ...
Morphology, internal structure and growth mechanism of electrodeposited Ni and Co powders
(Springer, New York, 2006)
In this paper the morphology (SEM analysis), the internal structure (cross-section analysis) and the growth mechanism of Ni and Co powders electrodeposited from ammoniacal electrolyte are investigated. It is shown that ...
Improvement of Ethanol Fermentation of Corn Semolina Hydrolyzates with Immobilized Yeast by Medium Supplementation
(University of Zagreb, 2009)
The possibilities of improving ethanol fermentation of enzymatically obtained corn semolina hydrolyzates with alginate-immobilized yeast Saccharomyces cerevisiae var. ellipsoideus by medium supplementation with mineral ...
Nanosilica/PMMA composites obtained by the modification of silica nanoparticles in a supercritical carbon dioxide-ethanol mixture
(Springer, New York, 2009)
Nanosilica/poly(methyl methacrylate) (PMMA) composites are used to improve the mechanical properties of neat PMMA polymer. In order to obtain superior mechanical properties, it is essential to achieve good bonding between ...
Electrocatalytic behaviour of MoPt3 intermetallic phase for hydrogen evolution in acid solution
(Ecole Polytechnique de Montreal, 2004)
Metallurgicaly prepared MoPt3 intermetallic compound has been investigated as electrocatalyst for the cathodic evolution of hydrogen (HER) in 0.5 mol dm-3 HClO4 solution at 298 K. The HER on activated and non-activated ...
