Design of symmetric planar fishnet metamaterials for optical wavelength range
(27th International Conference on Microelectronics, MIEL 2010 - Proceedings, 2010)
In this work we analyze fishnet-type optical metamaterials with full electromagnetic symmetry, fabricated in an ultrathin, freestanding film (self-supported nanomembrane). We utilized the finite element method to simulate ...
Alumina production from purified Bayer liquor / Proizvodnja glinice iz pročišćene Bayerove otopine
(Hrvatska: Hrvatsko društvo kemijskih inženjera i tehnologa
(HDKI), 2019)
Removal of some impurities from Bayer liquor, such as zinc compounds, allows obtaining alumina with low content of impurities incorporated in the crystalline structure. Impurities in alumina influence the quality of products ...

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 ...

Periodically operated CSTRs with simultaneous modulation of feed concentration and flow-rate- Nonlinear frequency response approach
(10th European Congress of Chemical Engineering (ECCE 10), Nice, France, 2015)
Possible improvements of chemical reactor performance through periodic modulation of one or more inputs have been investigated for several decades. In our previous investigations we have introduced the nonlinear frequency ...
Evaluation of possible performance improvement through periodic operation for the reaction of acetic acid anhydride hydrolisis
(European Symposium on Chemical Reaction Engineering (ESCRE 2015), Munich, Germany, 2015)
The nonlinear frequency response (NFR) method is a relatively new, fast and easy, analytical method for evaluating the performance of forced periodically operated chemical reactors. The method has been introduced in our ...
Resonant frequency and phase noise of nanoelectromechanical oscillators based on two-dimensional crystal resonators
(Elsevier, 2014)
This study presents a theoretical analysis of one of the most promising nanoelectromechanical (NEMS) components - A NEMS oscillator. The analyzed oscillator contains a stretched circular plate, fabricated of two-dimensional ...
Exploiting the Nonlinear Frequency Response Method to Evaluate the Potential of Forced Periodic Operation of Reactors
(German reaction Engineering Meeting (DECHEMA), Wuerzburg, Germany, 2016)
Forced periodic operation of chemical reactors possess significant potential to improve numerous performance criteria. The corresponding analysis of reaction systems and the estimation of the magnitude of possible performance ...
Biodiesel synthesis over green catalyst: The effect of thermal treatment of CaO/Zeolite precursor on catalytic activity
(Belgrade : Serbian Chemical Society, 2019)
The green CaO/Zeolite catalyst for methanolysis of fatty oils was synthesized entirely from the waste materials. CaO derived from chicken eggshell was loaded onto fly ashbased zeolite catalyst carrier by the wet impregnation ...
