Preparation and characterization of Me2O3-CeO2 (Me = B, Al, Ga, In) mixed-oxide catalysts
(Amer Chemical Soc, Washington, 2007)
The present work is focused on the synthesis and characterization of ceria-based mixed oxides. Ceria was combined with the other oxides from group III, with the intention of improving the catalytic properties I of thus ...
Influence of mechanical activation on the structure of ultrafine BaTiO3 powders
(Elsevier Science Sa, Lausanne, 2009)
The influence of mechanical activation in a planetary ball mill on the change of the structure of BaTiO3 powders has been investigated. The particle size distribution of the nonactivated and activated samples was measured ...
Fermentation characteristics of novel Coriolus versicolor and Lentinus edodes kombucha beverages and immunomodulatory potential of their polysaccharide extracts
(Elsevier, 2021)
Medicinal mushrooms, Coriolus versicolor and Lentinus edodes are extremely attractive as nutraceuticals. Here we used fruiting bodies to prepare novel kombucha beverage. Microbiological, physicochemical and chemical ...
Electrical properties of screen printed BaTiO3 thick films
(Elsevier Sci Ltd, Oxford, 2004)
The deposition of thick film pastes by screen-printing is a relatively simple and convenient method to produce thicker layers with thickness up to 100 mum. In the present work, the barium titanate thick films were prepared ...
Effect of N deficiency on leaf growth and cell wall peroxidase activity in contrasting maize genotypes
(Springer, Dordrecht, 2004)
Two maize genotypes differing in leaf elongation rate (high-LER and low-LER) were used for the investigation of the effects of nitrogen deficiency on leaf growth and development and activity of enzyme cell wall peroxidase ...
Influence of thermal treatment on phenolic compounds and antioxidant properties of oak acorns from Serbia
(Elsevier Sci Ltd, Oxford, 2007)
The aim of the present work was to investigate and compare phenolic compounds and antioxidant activity of methanol extracts of Quercus robur and Quercus cerris acorn kernels obtained before and after thermal treatment. ...
Energy efficiency optimization of combined ventilation systems in livestock buildings
(Elsevier Science Sa, Lausanne, 2010)
Good ventilation system in livestock buildings is necessary for removing excess moisture and heat and for improving building environment in general. Natural ventilation does not require energy consumption and on the other ...
Resistance of Listeria monocytogenes, Escherichia coli O157:H7 and Campylobacter jejuni after exposure to repetitive cycles of mild bactericidal treatments
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
While maintaining nutritional and sensorial attributes of fresh foods mild processing technologies generally deliver microbiologically perishable food products. Currently little information exists on possible increase in ...
Energy consumption for different greenhouse constructions
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
In this paper the influence of greenhouse construction on energy efficiency in winter lettuce production was estimated for four different double plastic covered greenhouses in Serbia region. Plastic coverings were introduced ...
LaMO3 (M = Mg, Ti, Fe) perovskite type oxides: Preparation, characterization and catalytic properties in methane deep oxidation
(Elsevier, Amsterdam, 2008)
Two new series of perovskite-type oxides LaMO3 (M = Mg, Ti, Fe) with different ratio Mg/Fe (MF) and Ti/Fe (TF) in the B cation site were prepared by annealing the precursor, obtained by the mechanochemical activation (MCA) ...
