Magnetic field influence on silicon surface periodic structures obtained by plasma flow action
(25th International Conference on Microelectronics, MIEL 2006 - Proceedings, 2006)
External magnetic field influence on silicon submicron surface periodic structures obtained by the action of nitrogen supersonic quasistationary compression plasma flow (CPF) is studied. CPF is generated by magnetoplasma ...
Hardness response and adhesion of thin copper films on alloy substrates
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear engineering, 2017)
Microhardness test is the most commonly used
method for assessing the mechanical properties of thin films.This testing method uses controlled contact at a single point of an indenter and chosen material which induces the ...
Oxygen reduction on polycrystalline Au modified by nanosized Pd islands
(Belgrade : Institute of Technical Sciences of the Serbian Academy of Sciences and Arts, 2011)
Oxygen reduction reaction was studied on polycrystalline gold, Au(poly), modified by nanosized palladium islands. Linear sweep voltammetry measurements were performed using rotating Au-disk electrode in oxygen saturated ...
Oxygen Reduction on Polycrystalline Pt Electrode Modified by Acetonitrile in Neutral Electrolyte
(Nice : International Society of Electrochemistry, 2010)
Oxygcn reduction was studied on pure polyclrystalline PI electrode and on one modified by chemisorbed acetonitrile in neutral solutions containing sulphate or chloride anions. Measurements were performed on polycrystalline ...
EBG band-stop filter with suppression of 3 spurious stop-bands
(Final Program and Book of Abstracts - iWAT 2010: 2010 International Workshop on Antenna Technology:, 2010)
Based on the well known theory of infinite periodic structures, analytical theory of EBG (electromagnetic band gap) cells suppressing 3 higher (spurious) stop-bands is developed. Using such cells in a cascade the ...
Predikcija brzine vetra na teritoriji Libije primenom veštačkih neuronskih mreža
(Univerzitet u Beogradu - Mašinski fakultet, 2018)
Libija je zemlja bogata naftom i prirodnim gasom čije učešće u proizvodnji električne energije je preko 90%.
Međutim, sve više su u upotrebi i obnovljivi izvori energije, kao što je energija vetra. U Libiji postoji ...
Adsorption-desorption phase noise in RF MEMS/NEMS resonators
(10th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting, 2011)
In this paper the analysis is presented of the dependence of adsorption-desorption phase noise in MEMS/NEMS resonators of their resonant frequency, operating pressure and temperature. Results of the analysis are useful for ...
Cirkularna ekonomija: primena zelene hemije u privrednom sektoru
(Beograd : Univerzitet u Beogradu - Ekonomski fakultet, Centar za izdavačku delatnost, 2023)
U današnjem svetu, suočeni smo sa sve većim izazovima u očuvanju životne sredine i potrebom za održivim razvojem. Koncept cirkularne ekonomije, od teorijskih analiza prešao je i u praktičnu primenu širom Evrope. Međutim, ...
Investigation of interface and surface energy states in semiconductors by PA method
(European Physical Journal: Special Topics, 2008)
The photoacoustic (PA) signal should generally change with the extent of damage, in the form of surface energy states (SES) or interface energy states (IES). For a mechanically, chemically or particles processed (Ar-plasma ...
Incorporating a Lowpass Filter into a Very Wide Bandpass Filter to Suppress Harmonics
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear angineering, 2021)
This paper presents an algorithm for suppression of higher harmonics in response of the very wide bandpass filter (WBPF). Lowpass filter (LPF) is incorporated into the very wide bandpass filter to suppress harmonics. The ...
