Electron Delocalization in Electron-Deficient Alkenes and Push-Pull Alkenes
(Wiley-V C H Verlag Gmbh, Weinheim, 2017)
We have studied pi electron delocalization in electron- deficient alkenes and push- pull alkenes by means of natural bond orbital analysis at the B3LYP/6-311+ G(d,p) level. The study revealed that the rarely mentioned pi ...
Synthesis and performance of polymer based magnetic composite sensing element
(Inst Materials Physics, 2015)
The commercial multi-mode optical fiber was coated with magnetic composite material prepared using Nd-Fe-B permanent magnet powder dispersed in poly (ethylene-co-vinyl acetate)-EVA. Characterization of microstructure, ...
Return map analysis of the highly nonlinear Bray-Liebhafsky reaction model
(Springer Netherlands, 2016)
By numerically simulated Bray-Liebhafsky (BL) reaction under a continuously fed well stirred tank reactor (CSTR) conditions, we discussed the attractors and Poincar, 1D maps with respect to flow rate as the control parameter. ...

In this study, we compared the compositions, antimicrobial and potential antioxidant activities of essential oils of two Thymus endemic, wild-growing species - T. malyi Ronninger and T. lykae Degen et Jay. No information ...
Speciation of Trace and Major Elements from Coal Combustion Products of Serbian Power Plants (I)-"Kostolac A" Power Plant
(Taylor & Francis Inc, Philadelphia, 2011)
In order to examine association patterns and pollution potential of trace and major elements from coal ash, six composite samples of fresh, filter fly, and aged dump coal ash from "Kostolac A" power plant located 100 km ...
Response surface optimization for activation of bentonite using microwave irradiation
(Clay Minerals Soc, Chantilly, 2012)
Microwave irradiation as a means for heating bentonites during acid activation has been investigated in the past but it has never been optimized for industrial applications. The purpose of this study was to apply a factorial ...
Antimicrobial activity of essential oils and ethanol extract of Phlomis fruticosa L. (Lamiaceae)
(John Wiley and Sons LtdJohn Wiley and Sons Ltd., 2000)
The essential oils and an ethanol extract of Phlomis fruticosa L. were evaluated for antibacterial and antifungal activities. Seven bacterial and seven fungal species were used. Among them were human, animal and plant ...
Antioxidant activity of nine Fabaceae species growing in Serbia and Montenegro
(Elsevier, 2008)
The aim of this study was to investigate antioxidant capacity of nine Fabaceae species collected on the mountains of Serbia and Montenegro. Antioxidant assays with various reaction mechanisms were used, including total ...
Studying of liquid thermolysis products of various types of immature kerogen in sedimentary lacustrine rocks from the valjevo-Mionica basin, Serbia, and the effect of Pt4+ and Ru3+ ions on their yield and the hydrocarbon composition
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Liquid thermolysis products of various types of immature kerogen from sedimentary lacustrine rocks from the Valjevo-Mionica basin in Serbia were studied to evaluate the generation potential of kerogen contained in the ...
