Reuse of waste sulfur as a binding agent in concrete
(Association for Promotion of Holistic Approach to Environment, 2018)
Mainly due to the strict global environmental regulations regarding the oil and gas
refining processes, which limit the maximum quantity of sulfur in combustibles, the
availability of waste sulfur has been considerably ...
Mixed-mode resins: taking shortcut in downstream processing of raw-starch digesting α-amylases
(Serbian Biochemical Society (Belgrade), 2015)
Bacillus licheniformis 9945a α-amylase (BliAmy) has been described as potent enzyme for raw starch hydrolysis. Starch represents an inexpensive source for production of glucose, maltose syrups and fructose which are widely ...
Chromium, Nickel, and Cobalt in soils of Srem and C. Banat
(Ecological Movement of Novi Sad, 2017)
This paper reports the concentration and sources of chromium, nickel and cobalt in soil samples from the Srem and Central Banat (Vojvodina, Serbia). Different methods were applied to identify the sources of elements and ...
Superior photocatalytic properties of carbonized PANI/TiO2 nanocomposites
(Elsevier, 2017)
A simple bottom-up method for the preparation of novel and very efficient photocatalytic nanocomposite system based on carbonized form of polyaniline (PANI) and colloidal TiO2 nanocrystals has been developed. The carbonized ...
Binary oxide ceramics for enhanced phenols degradation under simulated Solar light
(Wiley, Hoboken, 2018)
Solvothermal synthesis of ZrO2-TiO2 binary oxides and pure counterparts at 150 degrees C in water/isopropanol media is presented. Titanium (IV) isopropoxide and zirconium (IV) propoxide were used as precursors. XRD and TEM ...
Nutritive and biological values of some Pyrus varieties growing in Serbia
(University of Belgrade - Falulty of chemistry, 2011)
The aim of this study was to characterize twelve different allochthonous varieties of Pyrus species grown on the territory of Serbia. These are: Beurre Clairgeau, Abbate Fetel, General Leclerc, Beurre Bosc, Conference, ...
The particle size distribution of Ag powders obtained by chemical and electrochemical processes of synthesis
(Bor, Serbia : University of Belgrade, Technical Faculty in Bor, 2017)
The particle size distribution and the specific surface area (SSA) of silver powders obtained by chemical and electrochemical processes of synthesis have been analyzed . Silver particles produced by a chemical reaction ...
The influence of the size and surface modification of TIO2 nanoparticles on the rheological properties of alkyd resin / Uticaj veličine nanočestica TIO2 i njihove površinske modifikacije na reološka svojstva alkidne smole
(Association of Chemical Engineers of Serbia, 2013)
Spherical TiO2 particles of different size were dispersed in alkyd resin based on soybean oil. Four samples of TiO2 particles were used, three commercial and one obtained by acid catalyzed hydrolysis of titanium ...
Structural, optical and photodegradation properties of pure and Fe-doped titania nanoparticles probed using simulated Solar light
(Elsevier Sci Ltd, Oxford, 2016)
We report the successful, low temperature synthesis of pure and Fe-doped titania nanoparticle (NP) powders, using organic Ti- and Fe-precursors. The properties of the synthesized titania based materials were obtained using ...
Preparation and Properties of Short Oil Alkyd Resin/TiO2 Nanocomposites Based on Surface Modified TiO2 Nanoparticles
(Hoboken : Wiley, 2018)
Alkyd resin/TiO2 nanocomposites (NC) were prepared from short oil alkyd resin and TiO2 nanoparticles (NPs) surface modified with in situ formed imine ligand, based on 3,4-dihydroxybenzaldehyde and oleylamine, or with three ...
