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 ...
Modelling and Multi-Criteria Analysis of Anaerobic Digestion Process to Get Upgraded Methane from Bio-Residues in the City of Reykjavik
(MDPI, 2019)
Anaerobic digestion of urban organic wastes, farming slurries or sewage sludge is a
common practice in waste treatment plants. In the city of Reykjavik, the organic waste fraction
constituted by 60% of biomass and 40% ...
Intensification of a chemical reactor for methanol synthesis through forced periodic operations- Evaluation based on Nonlinear Frequency Response Analysis
(2nd International Process Intensification Conference, Leuven, Belgium, 2019)
In this work, the NFR method is implemented for evaluation of possible improvement for the reaction of methanol synthesis by hydrogenation of CO and CO2, using a standard Cu/ZnO/Al2O3 catalyst. For start, a forced periodically ...
Prečišćavanje otpadnih voda primenom ozonizacije / Purification of waste water using ozonization
(Beograd : Beogradska politehnika, 2019)
Usled razvoja industrije i rastom populacije tokom poslednjih godina javljaju se
problemi u vezi sa otpadnim vodama iz proizvodnje koje je neophodno rešavati na ekološki i
ekonomičan način. Sve otpadne vode iz postrojenja ...
A consideration of the use of ICTM SP-12 pressure sensor for ultrasound sensing
(Belgrade : ETRAN SocietyBelgrade : Akademska misao, 2019)
A consideration study for the application of the pressure sensor SP-12 developed and produced by ICTM CMT as an ultrasound sensor is given. The interaction of ultrasound with the sensor’s membrane was analytically described, ...
Analysis of Intrinsic Stochastic Fluctuations of the Time Response of Adsorption-Based Microfluidic Bio/Chemical Sensors: the Case of Bianalyte Mixtures
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Real-time in situ operation of bio/chemical sensors assumes detection of chemical substances or biological specimens in samples of complex composition. Since sensor selectivity cannot be ideal, adsorption of particles other ...
Morphological variation within the Placoneis elginensis (W.Gregory) E.J.Cox species complex
(Belvaux, Luxembourg : Luxembourg Institute of Science and Technology, 2019)
Freshwater diatom species Placoneis elginensis (W.Gregory) E.J.Cox was originally described in 1856 as Pinnularia elginensis W.Gregory. Because it is often confused with other species, its distribution requires closer ...
Degradation of organophosphorus insecticide by chlorine dioxide / Degradacija organofosfornog insekticida pomoću hlor-dioksida
(Serbian Chemical Society, Belgrade / Srpsko hemijsko društvo, Beograd, 2019)
In this paper, the degradation of organophosphorus insecticide (malathion) with chlorine dioxide was investigated. Degradation was studied in deionized water. Optimization of degradation conditions was examined under light ...

(Bulgarian Federation of Speleology, 2019)
Cyanobacteria and algae, ecological, and parameters
of biofilm developed at rock substratum
at the entrance of Samar Cave (Serbia),
were analysed seasonally. Of 141 taxa, Cyanobacteria
were dominant (coccoid forms ...
Exploring anatomy of experiment with DFT: Quantitative structure-activity relationship of Substituted arylazo pyridine dyes in Photocatalytic reaction
(University of Pardubice, 2019)
A series of arylazo pyridone dyes was synthesized by changing the type of the substituent
group in the diazo moiety, ranging from strong electron-donating to strong electronwithdrawing
groups. The structural and electronic ...
