Porous cordierite-supported polyethyleneimine composites for nickel(II) and cadmium(II) ions removal
(Desalination Publ, Hopkinton, 2020)
Industrial/technological growth is directly connected with environmental pollution, but its influence can be minimized through pollution abatement approaches such as the treatment of industrial wastewater. In this study, ...
ANN prediction of the efficiency of the decolourisation of organic dyes in wastewater by plasma needle
(Srpsko hemijsko društvo, Beograd, 2020)
In this paper, the results of decolourisation of Reactive Orange 16 (RO 16), Reactive Blue 19 (RB 19) and Direct Red 28 (DR 28) textile dyes in aqueous solution by plasma needle are presented. Treatment time, feed gas flow ...
Synthesis, solvent interactions and computational study of monocarbohydrazones
(Springer International Publishing Ag, Cham, 2020)
Carbohydrazones are compounds that are increasingly studied due to their wide potential biological activity. Monocarbohydrazones (mCHs), as one of the carbohydrazone derivatives, so far have been poorly investigated. For ...
Possibility of achieving an acceptable response rate of gas-filled surge arresters by substitution of alpha radiation sources by selection of electrode material and the electrode surface topography
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
The possibility of substituting the usage of a radioactive a-source to improve the characteristics of the gas surge arrester is considered in this paper. The solution to this problem is sought in the engineering of the ...
Analysis of thermophysical properties of binary systems containing ethyl acetate and 1-propanol or 1-butanol
(Savez hemijskih inženjera, Beograd, 2020)
The aim of this research is the experimental determination of density, viscosity, refractive index and speed of sound for binary mixtures of the ester ethyl acetate and alcohols. Experimental measurements were carried out ...
Sensitivity analysis of the variational model for the particulate expansion of fluidized beds
(Taylor & Francis Inc, Philadelphia, 2020)
Fluidization experiments were performed by using spherical and non-spherical particles to examine the sensitivity of the variational model to three input parameters: U-mf, epsilon(mf) and U-t. Several correlations for U-mf, ...
Thermo-responsive hydrogels based on poly(N-isopropyl- acrylamide) and hyaluronic acid cross-linked with nanoclays
(Srpsko hemijsko društvo, Beograd, 2020)
Semi-interpenetrating polymer networks (SIPN) based on thermo-responsive poly(N-isopropylacrylamide) (PNIPA) and water-soluble sodium salts of linear hyaluronic acid (Na-HA) were physically cross-linked with synthetic ...
Improvement and modification of the energy-dispersive X-ray fluorescence method for the determination of metal elements in cement leachates - A chemometric approach
(Journal of the Serbian Chemical Society, 2020)
A modification of an analytical procedure for the energy-dispersive X-ray fluorescence (EDXRF) quantification of ten chemical elements (As, Ba, Cd, Co, Cr, Cu, Mo, Ni, Pb and Zn) in the leachates obtained from cement binders ...
Influence of cold-rolling deformation and annealing temperature on the grain growth of al-4%mg-mn alloy
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2020)
The propensity of an alloy toward an abnormal grain growth (AGG) severely limits the annealing temperature range, capability for hot forming, and deteriorates mechanical properties. In this work, the results of a study of ...
Thin-layer chromatography on reversed phase in the characterization of retention behaviour, lipophilicity, and pharmacokinetics of cyanoacetamide derivatives
(Journal of the Chilean Chemical Society, 2020)
Biological activity of a molecule is closely related to its lipophilicity. This significant parameter was determined for a group of potentially bioactive N-(4-phenylmonosubstituted)-2-cyanoacetamides applying thin-layer ...
