Printed Antenna Array with Flat-Top Radiation Pattern
(Berlin : Walter De Gruyter Gmbh, 2018)
printed antenna array consisting of 10 wide-band symmetrical pentagonal dipoles is presented. The feed network of impedance transformers is employed to provide appropriate amplitude and phase distribution necessary to ...
Fluidized bed combustion of pesticide-manufacture liquid wastes / Sagorevanje tečnog otpada fabrike pesticida u fluidizovanom sloju
(Serbian Chemical Society, 2010)
Industrial liquid wastes can be in the form of solutions, suspensions, sludges, scums or waste oil and have organic properties. The objective of this work was to demonstrate the technical feasibility of a fluidized bed as ...
Differences in coating mechanism of structurally different aluminosilicates observed through the thermal analysis
(Springer, 2018)
Systematic modification of three structurally different minerals (zeolite, mica, and vermiculite) was carried out with the aim of determining the modification mechanism and exposing the hydrophobic surface that can be used ...
A study of the structural and morphological properties of Ni-ferrite, Zn-ferrite and Ni-Zn-ferrites functionalized with starch
(Elsevier Sci Ltd, Oxford, 2018)
Zinc-ferrite, nickel-ferrite and mixed nickel-zinc ferrites were successfully synthesized via the thermal decomposition method from acetylacetonate complexes. To control the particle size and enhance dispersibility in an ...

Negative Refractive Index Metasurfaces for Enhanced Biosensing
(MDPI, 2011)
In this paper we review some metasurfaces with negative values of effective refractive index, as scaffolds for a new generation of surface plasmon polariton-based biological or chemical sensors. The electromagnetic properties ...
Electrocatalysis of hydrogen evolution reaction on tri-metallic Rh@Pd/Pt(poly) electrode
(Oxford : Pergamon-Elsevier Science Ltd, 2018)
Hydrogen evolution reaction (HER) was investigated in alkaline solution on tri-metallic Rh"Pd/Pt(poly) electrode, prepared by spontaneous deposition of Rh on top of Pd/Pt(poly) electrode with intermediate Pd coverage of ...
Comparison of liquid and liquid-gas phase plasma reactors for discoloration of azo dyes: Analysis of degradation products
(Wiley-V C H Verlag Gmbh, Weinheim, 2018)
Three plasma systems are used for decomposition of two organic textile dyes. The highest discoloration efficiency over 90% is reached in the water falling film DBD when maximal energy of 270 and 450kJL(-1) is applied into ...
