Solvent, structural, quantum chemical study and antioxidative activity of symmetrical 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides
(Springer, New York, 2018)
15 symmetric 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides were synthesized in this work. Their structures were characterized using IR, H-1 and C-13 NMR, and UV-Vis spectroscopy. DFT calculations indicated ...
High temperature transesterification of soybean oil with methanol using manganese carbonate as catalyst
(Savez hemijskih inženjera, Beograd, 2018)
The manganese carbonate catalyst, prepared by precipitation method, was used in transesterification of soybean oil under subcritical condition of methanol. Catalyst samples were characterized by X-ray diffraction (XRD), ...
Estimation of Cadmium uptake by tobacco plants from laboratory leaching tests
(Taylor & Francis Inc, Philadelphia, 2018)
The objective of the present study was to determine the impact of cadmium (Cd) concentration in the soil on its uptake by tobacco plants, and to compare the ability of diverse extraction procedures for determining Cd ...
Ad-hoc intercomparison of four different radon exhalation measurement methods
(Oxford Univ Press, Oxford, 2018)
It is indicated that the exposure to radon originating from the building materials is not negligible and the radon exhalation measurement should get more attention in the future. The experience with four different methods ...
Alumina Particles Doped With Ferric as Efficient Adsorbent for Removal of Reactive Orange 16 from Aqueous Solutions
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
Ferric oxide doped alumina particles were prepared via the sol-gel method and their performance as Reactive Orange 16 adsorbent was evaluated. The concentrations of the Reactive Orange 16 were monitored using a UV-Vis ...
Cleaner and energy efficient production: a case study
(Gheorghe Asachi Technical University of Iasi, Romania, 2018)
A project called 'Cleaner Production' is conducted in the organization of the Cleaner Production Centre of Serbia at the Faculty of Technology and Metallurgy, University of Belgrade and the United Nations Industrial ...
Polyaniline stabilization of magnetic particles and immobilization of alpha-amylase
(Savez hemijskih inženjera, Beograd, 2018)
Magnetic particles (MAG), obtained by standard procedure of coprecipitation of Fe2+ and Fe3+ in an excess of ammonia, and polyaniline modified magnetic particles MAG-PANI were used as carriers for immobilization of a-amylase ...
Processing and characterization of UHMWPE composite fibres with alumina particles in poly(ethylene-vinyl acetate) matrix
(Sage Publications Ltd, London, 2018)
Processing of hybrid composites represents a challenge for engineers where the aim is to establish compatibility among several materials. The aim of this study is to evaluate the effects of different sizes and morphologies ...
In vivo investigation of soft tissue response of novel silver/poly(vinyl alcohol)/ graphene and silver/poly(vinyl alcohol)/chitosan/graphene hydrogels aimed for medical applications - the first experience
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2018)
In this paper, we have shown for the first time the soft tissue response of novel silver/poly(vinyl alcohol)/graphene (Ag/PVA/Gr) and silver/poly(vinyl alcohol)/chitosan/graphene (Ag/PVA/CHI/Gr) nanocomposite hydrogels ...
Antimicrobial Activity of Thiocarbohydrazones: Experimental Studies and Alignment-Independent 3D QSAR Models
(Wiley-VCH Verlag Gmbh, Weinheim, 2018)
Due to the rise of microbial strains resistant to conventional therapies, there is an urgent need for finding the new antimicrobial chemotypes. Heterocyclic compounds such as thiocarbohydrazones (TCHs) are able to interact ...
