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, ...
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 ...
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 ...
Forced Periodic Operation: Effect of shapes for two simultaneously imposed modulations
(German reaction Engineering Meeting (DECHEMA), Wuerzburg, Germany, 2019)
The classical design of continuous chemical reactors exploits steady-state operation, which is optimized and maintained by appropriate control systems. Nevertheless, it is well-known that the reactor performance can be ...
Modified eggshell catalyst for transesterification of sunflower oil: The effects of catalyst loading on FAMEs content
(Belgrade : Serbian Chemical Society, 2019)
Modified highly active CaO catalyst (ESCHC-600) derived from waste chicken eggshells were prepared and used in the transesterification of sunflower oil. Eggshells were subjected to calcination-hydration-calcination (CHC) ...
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 ...
Biodegradation of selected PCBs by microorganisms isolated from PCBs polluted environment

Poster presented at: 39th International Symposium on Halogenated Persistent Organic Pollutants Dioxin, 25-30.08.2019, Kyoto, Japan.
Cobalt impregnated natural and acid modified montmorilloniteas catalysts in heterogeneous catalytic oxidation of nicotine in the presence of Oxone®
(Belgrade : Serbian Ceramic Society, 2019)
Nicotine i.e. (S)-3-(1-methylpyrrolidin-2-yl) pyridine is an alkaloid present in significant quantities in tobacco leaves and can be found in wastewaters as an aftermath of tobacco manufacturing. Natural Wyoming originated ...
Experimental measurements and theoretical simulations of alcohol and hydrocarbon binary systems / Eksperimentalna merenja i teorijske simulacije binarnih sistema alkohola i ugljovodonika
(Serbian Chemical Society, Belgrade / Srpsko hemijsko društvo, Beograd, 2019)
Experimental and theoretical methods were used to study two mixtures, 1-hexanol with nhexane and cis-3-hexen-1-ol with n-hexane. The experimental technics were used to determine excess molar volume and viscosity deviations ...
Effects of preparation conditions on the catalytic activity of chicken eggshell catalysts for the transesterification of oils to biodiesel
(DECHEMA e.V., 2019)
Eggshell based catalysts were synthesized by calcination (600 and 900 ºC, 4 h) of raw and rehydration (RH) modified (RH-temperature of 80 ºC, S/L ratio of 1/5, and RH-time of 6 h) eggshell. After RH-treatment, the sample ...
