Oil pollution in the vinicity of a heating plant in New Belgrade (Serbia) – influence on the quality of the surrounding soil and sediments
(ACE - Association of Chemistry and the Environment, 2015)
Petroleum products have been used for decades in the plants for district heating in Belgrade (Capital of Serbia). The most used derivative for this purpose is a heavy oil fuel. Additionally, raw petrol and eco-diesel are ...
Magnetic Anisotropy in "Scorpionate" First-Row Transition-Metal Complexes: A Theoretical Investigation
(Wiley-V C H Verlag Gmbh, Weinheim, 2015)
In this work we have analyzed in detail the magnetic anisotropy in a series of hydrotris(pyrazolyl)borate (Tp(-)) metal complexes, namely [VTpCl](+), [CrTpCl](+), [MnTpCl](+), [FeTpCl], [CoTpCl], and [NiTpCl], and their ...
The effect of steric repulsion on the torsional potential of n-butane: a theoretical study
(Oxford : Pergamon-Elsevier Science Ltd, 2015)
The origin of the rotational barriers in n-butane and gauche conformational energy, the prototypes of steric repulsion, has been re-examined by using energy decomposition analysis. The Pauli repulsion was found to be an ...
Influence of sintering temperature on low level laser (LLL) destruction of low cement high alumina refractory concrete
(Elsevier, 2015)
Low level laser (LLL) was applied to induct destruction of the low cement high alumina refractory concrete (LCC) samples. Three different series of samples were used in the experiment: a reference one dried at 105 degrees ...
Experimental and theoretical investigation of octahedral and square-planar isothiocyanato complexes of Ni(II) with acylhydrazones of 2-(diphenylphosphino)benzaldehyde
(Oxford : Pergamon-Elsevier Science Ltd, 2015)
Octahedral and square-planar isothiocyanato complexes of Ni(II) with the condensation derivative of 2-(diphenylphosphino)benzaldehyde and Girard's T reagent were synthesized and characterized by elemental analysis, IR ...
Exploitation of neglected horseradish peroxidase izoenzymes for dye decolorization
(Elsevier Sci Ltd, Oxford, 2015)
Horseradish peroxidase (HRP) is enzyme first described more than 200 years ago and yet there are still some aspects of this potent enzyme to be tackled. Researchers were focused on most abundant isoenzyme HRP CIA while ...
Efikasnost primene modela određivanja koeficijenta biorazgradnje otpadnih voda / Efficiency of the model application to determine the coefficient of biodegradation of wastewater
(Udruženje za tehnologiju vode i sanitarno inženjerstvo / Association for water technology and sanitary engineering, 2015)
u laboratorijskim uslovima, teško se može sagledati kinetika biorazgradnje i odrediti potrebni kinetički parametri za projektovanje postrojenja za prečišćavanje otpadnih voda. Iz tih razloga u ovom radu prikazana je primena ...
Novi tehnološki postupak za dobijanje fosfatnog đubriva iz apatita dejstvom Acidithiobacillus sp. u prisustvu pirita
(University of Belgrade - Institute of Chemistry, Technology and MetallurgyBelgrade : Brem group d.o.o., 2015)
U cilju rada sa autohtonim mikroorganizmom koji je prirodno optimizovan na klimatske uslove i rast na piritu, izolovan je i okarakterisan hemolitoautotrofni mikrorganizam Acidithiobacillus sp. B2 iz jezera Robule (Bor, ...
Synthesis and performance of polymer based magnetic composite sensing element
(Inst Materials Physics, 2015)
The commercial multi-mode optical fiber was coated with magnetic composite material prepared using Nd-Fe-B permanent magnet powder dispersed in poly (ethylene-co-vinyl acetate)-EVA. Characterization of microstructure, ...
Sonophotocatalytic degradation of dye CI Acid Orange 7 by TiO2 and Ag nanoparticles immobilized on corona pretreated polypropylene non-woven fabric
(Elsevier, 2015)
This study discusses the possibility of using corona pre-treated polypropylene (PP) non-woven fabric as a support for immobilization of colloidal TiO2 and Ag nanoparticles in order to remove dye C.I. Acid Orange 7 from ...
