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 ...
Degradation behaviour of PCL/PEO/PCL and PCL/PEO block copolymers under controlled hydrolytic, enzymatic and composting conditions
(Elsevier Sci Ltd, Oxford, 2017)
Short-term hydrolytic and enzymatic degradation of poly(epsilon-caprolactone) (PCL), one series of triblock (PCL/PEO/PCL) and the other of diblock (PCL/PEO) copolymers, with a low content of hydrophilic PEO segments is ...
Cascade luminescence and antibacterial behavior of fluorapatite nanopowder co-doped with Pr3+, NO3− and CO32− ions
(Springer, 2023)
In this study, luminescence and antibacterial behavior of pure fluorapatite (FAp) and praseodymium-nitrate-carbonate co-doped fluorapatite (PrNCFAp) nanopowders were investigated. Uniform nanopowders were synthesized by ...
Decolorization of Azo Dye Through the Utilization of Microbial Fuel Cells Connected in Parallel Confiouration
(Chemical Society of Montenegro, 2023)
Microbial fuel cells (MFCs) are a promising technology that has the potential to solve environmental problems while simultaneously generating electricity. Thanks to the direct use of energy from the substrate and its ...

Heavy metal concentrations in the soil near illegal landfills in the vicinity of agricultural areas—artificial neural network approach
(Springer Nature, 2023)
Purpose To anticipate the impact of illegal landfills, development of new models should become a part of environmental risk management strategies. One of such approaches includes applications of the artificial neural network ...
Oil pollution in the vinicity of a heating plant in New Belgrade (Serbia) – influence on the quality of the surrounding soil and sediments
(ACE - Association of Chemistry and the Environment, 2015)
Petroleum products have been used for decades in the plants for district heating in Belgrade (Capital of Serbia). The most used derivative for this purpose is a heavy oil fuel. Additionally, raw petrol and eco-diesel are ...
Solid-state silica gel-catalyzed synthesis of fluorescent polysubstituted 1,4- and 1,2-dihydropyridines
(Great Britain : Royal Society of Chemistry, 2023)
We present the green, highly atom-economical, solid-state silica gel-catalyzed synthesis of polysubstituted
1,4- and 1,2-dihydropyridines (DHPs) from commercially available materials, amines and ethyl propiolate.
The DHP ...
Cysteine and cerium as green corrosion inhibitors for AA7049: Mixture vs. complexation
(Elsevier, 2022)
In this work new green corrosion inhibitors based on the synthesized cerium-cysteine complex on AA7049 aluminum alloy were analyzed and compared to the mixture of CeCl3 and cysteine in 0.1 M NaCl. The complex structures ...
Structure, configuration, conformation and quantification of the push pull-effect of 2-alkylidene-4-thiazolidinones and 2-alkylidene-4,5-fused bicyclic thiazolidine derivatives
(Oxford : Pergamon-Elsevier Science Ltd, 2010)
Structures of a series of push-pull 2-alkylidene-4-thiazolidinones and 2-alkylidene-4,5-fused bicyclic thiazolidine derivatives were optimized at the B3LYP/6-31G(d) level of theory in the gas phase and discussed with respect ...
