The influence of fly ash characteristics and reaction conditions on strength and structure of geopolymers
(Elsevier Sci Ltd, Oxford, 2015)
Reactivity of Class F fly ash (FA), development of strength, and structure of FA-based geopolymers, depending on the reaction conditions, were examined in this paper. The results of SEM/EDS and NMR analyses revealed that ...
Optimization of extraction of stinging nettle leaf phenolic compounds using response surface methodology
(Elsevier, Amsterdam, 2015)
A full three level factorial design was implemented for optimization of extraction parameters in order to maximize total phenolic (TP) yield from stinging nettle leaf. Factors considered were percentage of methanol in ...
Interactions of Molecules with cis and trans Double Bonds: A Theoretical Study of cis- and trans-2-Butene
(Wiley-VCH Verlag Gmbh, Weinheim, 2016)
Noncovalent interactions of cis- and trans-2-butene, as the smallest model systems of molecules with cis and trans double bonds, were studied to find potential differences in interactions of these molecules. The study was ...
In vitro control of multiplication of some food-associated bacteria by thyme, rosemary and sage isolates
(Elsevier Sci Ltd, Oxford, 2012)
Antibacterial activity of thyme, rosemary and sage isolates obtained by supercritical fluid extraction and hydrodistillation was investigated on Geobacillus stearotermophillus, Bacillus cereus, Bacillus subtilis var. niger, ...
Forecasting of Greenhouse Gas Emissions in Serbia Using Artificial Neural Networks
(Taylor & Francis Inc, Philadelphia, 2013)
Serbia is attempting to synchronize its development with the basic assumptions of sustainable development and, consequently, data about environmental impact are necessary. The main goal of this study was to investigate and ...
Effective valorisation of distillery stillage by integrated production of lactic acid and high quality feed
(Elsevier, Amsterdam, 2015)
Utilization of distillery stillage from bioethanol production for lactic acid and feed production was studied. The lactic acid fermentation of the stillage was performed by Lactobacillus rhamnosus ATCC 7469 and maximal ...
Impact of plasma treatment on acoustic properties of natural cellulose materials
(Springer, Dordrecht, 2019)
Low-temperature plasma is widely used in many surface treatment technologies for modifications of the physical properties of different polymeric materials. In the present work, we have examined the modification of acoustical ...
Volumetric, viscometric, spectral studies and viscosity modelling of binary mixtures of esters and alcohols (diethyl succinate, or ethyl octanoate plus isobutanol, or isopentanol) at varying temperatures
(Academic Press Ltd- Elsevier Science Ltd, London, 2017)
Density, viscosity and refractive index of four binary mixtures consisting of diethyl succinate or ethyl octanoate + 2-methyl-1-propanol or 3-methyl-1-butanol have been measured at atmospheric pressure and over the temperature ...
Determination of pharmaceuticals and pesticides in river sediments and corresponding surface and ground water in the Danube River and tributaries in Serbia
(Springer, Dordrecht, 2015)
The aim of this study was the development of analytical methods for the simultaneous determination of 25 selected pharmaceuticals, metabolites, and pesticides, belonging to the various chemical classes, in river sediments ...
Influence of a Low Content of PEO Segment on the Thermal, Surface and Morphological Properties of Triblock and Diblock PCL Copolymers
(Springer, Dordrecht, 2016)
Two series, one of triblock (PCL/PEO/PCL) and the other of diblock (PCL/PEO) copolymers were prepared by ring-opening polymerization of epsilon-caprolactone catalized with tin(II) octoate and by using dihydroxy or monohydroxy ...
