An example of suppression of spurious stop-bands of EBG band-stop filter
(Udruženje za mikrotalasnu tehniku i tehnologiju i IEEE MTT-S Chapter-a Srbije, Beograd, 2011)
Based on the well known theory of infinite periodic structures, analytical theory of EBG (electromagnetic band gap) cells suppressing 6 higher (spurious) stop-bands is developed. Using such cells in a cascade the ...
New method for monitoring of the oxygen reduction process in aqueous solutions / Nova metoda za monitoring procesa redukcije kiseonika u vodenim rastvorima
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2009)
Composite electrode material based on NaX zeolite and silver dispersed both inside zeolite cavities and between the zeolite crystals, in nitrogen purged 0.1M NaOH solution, yielded the cyclic voltammograms corresponding ...
Calculation of the Jahn-Teller parameters with DFT / Izračunavanje Jan-Telerovih parametara primenom teorije funkcionala gustine
(Serbian Chemical Society, 2019)
In this review, we present Density Functional Theory (DFT) procedure to calculate the Jahn-Teller (JT) parameters in a non-empirical way, which does not depend on the system at hand. Moreover, the Intrinsic Distortion Path ...
Immobilization of biocatalysts for enzymatic polymerizations: Possibilities, advantages, applications
(Elsevier Sci Ltd, Oxford, 2012)
Biotechnology also holds tremendous opportunities for realizing functional polymeric materials. Biocatalytic pathways to polymeric materials are an emerging research area with not only enormous scientific and technological ...
Do altered activities of superoxide dismutases and the level of NF-κB modulate the effects of gamma radiation in HeLaS3 cells?
(Serbian Chemical Society, 2007)
Most experimental models, including cell culture studies, have demonstrated that over-expression of manganese superoxide dismutase (MnSOD) in cells bearing a carcinoma phenotype has anti-proliferative and tumour suppression ...
Structural and electrochemical properties of nesting and core/shell pt/tio2 spherical particles synthesized by ultrasonic spray pyrolysis
(MDPI, 2020)
Pt/TiO2 composites were synthesized by single-step ultrasonic spray pyrolysis (USP) at different temperatures. In an in-situ method, Pt and TiO2 particles were generated from tetra-n-butyl orthotitanate and chloroplatinic ...
Degradation of anionic surfactants using the reactor based on dielectric barrier discharge
(Serbian Chemical Soc, Belgrade, 2016)
Two anionic surfactants (sodium lauryl sulfate - SDS and sodium dodecylbenzenesulfonate - SDBS) were treated with dielectric barrier discharge. Loss of surfactant activity, decrease in chemical oxygen demand (COD) and total ...
Bioremediation of groundwater contaminated with petroleum hydrocarbons applied at a site in Belgrade (Serbia) / Bioremedijacija podzemnih voda zagađenih naftnim ugljovodonicima primenjena u blizini termo-energetskog postrojenja u Beogradu
(Belgrade : Serbian Chemical Society, 2020)
Due to their extensive use, petroleum hydrocarbons are among the most common groundwater contaminants. Compared to the traditional methods of physical pumping of contamination from the aquifer and subsequent treatment ...
Microcystins: Potential risk factors in carcinogenesis of primary liver cancer in Serbia
(University of Novi Sad, Department of Geography, Tourism and Hotel Management, 2011)
The Primary Liver Carcinoma (PLC) is one of the most common malignant diseases in the world. In Central Serbia during the period from 2000 to 2006 the average incidence was 16.9/100 000 that complies to the European ...
The influence of chemical composition on microstructure, hardness and electrical conductivity of Ag-Bi-In alloys at 100 degrees C
(Serbia : Association of Metallurgical Engineers of Serbia AMES, 2017)
Considering possible applications and scarceness of literature data, Ag-Bi-In system was investigated in terms of microstructure, mechanical and electrical properties of ternary alloys from an isothermal section at 100 °C. ...
