Conceptual design for treatment of mining and metallurgical wastewaters which contains arsenic and antimony
(Association of Metallurgical Engineers of Serbia, 2012)
This paper presents a preliminary design for treatment of mining and metallurgical wastewaters (MMW) from the basin of antimony 'Zajača', which contains high concentrations of arsenic and antimony. MMW have been investigated ...
Mechanochemically synthesized CaO·ZnO catalyst for biodiesel production
(20th International Congress of Chemical and Process Engineering, CHISA 2012 and 15th Conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction, PRES 2012, 2012)
The transesterification of triglycerides (vegetable oil) with methanol using CaO·ZnO mixed oxides catalyst were conducted to produce Fatty Acid Methyl Esters (FAME), i.e. biodiesel. The catalysts were used in the methanolysis ...
Raman spectroscopy of bismuth silicon oxide single crystals grown by the Czochralski technique
(IOP Publishing Ltd, Bristol, 2013)
In this work, single crystals of bismuth silicon oxide (BSO; Bi12SiO20) have been grown by the Czochralski method. The growth conditions were studied. The critical diameter and the critical rate of rotation were calculated. ...

Solvatochromic and quantum chemical investigations of newly synthesized succinimides: substituent effect on intramolecular charge transfer
(Springer Wien, Wien, 2013)
Two series of 1-aryl-3-phenyl- and 1-aryl-3,3-diphenylpyrrolidine-2,5-diones were synthesized and their solvatochromic properties were studied in a set of 15 solvents of different polarity. The effect of specific and ...
A Study of Applicability of Nonlinear Frequency Response Method for Investigation of Gas Adsorption Based on Numerical Experiments
(Amer Chemical Soc, Washington, 2013)
A study of the applicability of the Nonlinear Frequency Response (NFR) approach for investigation of equilibrium and kinetics of gas adsorption, based on numerical simulations, is presented. Pressure responses of a batch ...
Particle velocities in quasi two-dimensional water fluidized beds of spherical particles
(Elsevier, Amsterdam, 2013)
Particle velocities have been measured in two-dimensional water fluidized beds of mono-sized spherical glass particles d(p) = 1.94, 2.98, 4.00 and 6.00 mm in diameter. For each particle size, a separate column was constructed ...
