Spin state relaxation of iron complexes: The case for OPBE and S12g
(Serbian Chemical Soc, Belgrade, 2015)
The structures of nine iron complexes that show a diversity of experimentally observed spin ground states were optimized and analyzed using the Density Functional Theory (DFT). An extensive validation study of the new S12g ...
Comparisons of formic acid oxidation at supported Pt catalyst and at low-index Pt single crystal electrodes in sulfuric acid solution / Poređenje oksidacije mravlje kiseline na PT katalizatoru na nosaču i na niskoindeksnim PT monokristalima u sumpornoj kiselini
(Serbian Chemical Society, 2003)
The oxidation of formic acid was studied at supported Pt catalyst (47.5 wt%. Pt) and a low-index single crystal electrodes in sulfuric acid. The supported Pt catalyst was characterized by the TEM and HRTEM techniques. The ...
Vacuum Fluctuations in Optical Metamaterials Containing Nonlinear Dielectrics
(Polish Academy of Sciences, 2009)
We investigated the influence of zero-point fluctuations (vacuum fluctuations, optical quantum noise) to the optical response of electromagnetic metamaterials containing dielectrics with third-order Kerr-like nonlinearity. ...
Atomic partial charges for mixed chloroammine chromium(III) complexes fitted to the molecular electrostatic potential
(Elsevier, 2012)
Using the RESP procedure partial atomic charges for six isomers of a series of octahedral complexes [Cr(NH3)(6-x)(Cl)(x)]((3-x)+) (x = 0, 1, 2, 3) were least-square fitted to the molecular electrostatic potential (MEP) ...
Bacterially generated Fe2(SO4)3 from pyrite, as a leaching agent for heavy metals from lignite ash / Bakterijski generisani Fe2(SO4)3 iz pirita kao agens za luženje elektrofilterskog pepela termoelektrane iz procesa sagorevanja lignita
(Serbian Chemical Society, 2007)
Investigations of heavy metals from lignite ash, which is a coal combustion by-product, have for years been very interesting from different aspects of environmental protection. In this study, the possibility of microbiological ...
P-nitrophenol electro-oxidation on a btma(+)-bentonite-modified electrode
(Clay Minerals Soc, Chantilly, 2012)
Phenol and its derivatives arc regarded as 'priority pollutants' and p-nitrophenol (p-NP), in particular, is of great interest due to its toxicity and frequent presence in waste waters and fresh waters. Straightforward, ...
Fractal analysis of bentonite modified with heteropoly acid using nitrogen sorption and mercury intrusion porosimetry / Fraktalna analiza bentonita modifikovanog heteropoli kiselinom korišćenjem podataka sorpcione analize i živine porozimetrije
(Serbian Chemical Society, 2011)
Experimental adsorption isotherms were used to evaluate the specific surface area and the surface fractal dimensions of acid-activated bentonite samples modified with a heteropoly acid (HPW). The aim of the investigations ...
Influence of the phase composition of refractory materials on creep
(International Institute for the Science of Sintering, Beograd, 2006)
In this paper, the relationship between the creeping effect and mineralogical characteristics of the applied binding phase for various refractory materials (high-alumina materials, with high or low impurity content, tar ...
Evaluation of genotoxic potential of avarol, avarone, and its methoxy and methylamino derivatives in prokaryotic and eukaryotic test models
(Taylor and Francis Ltd, 2017)
In this study, mutagenic and genotoxic potential of anti-tumor compounds avarol, avarone, and its derivatives 3′-methoxyavarone, 4′-(methylamino)avarone and 3′-(methylamino)avarone was evaluated and compared to cytostatics ...
Properties and efficiency of a Pt/Al2O3 catalyst applied in a solid fuel thermo-accumulating furnace / Osobine i efikasnost Pt/Al2O3 katalizatora u termo-akomulacionoj peći na čvrsto gorivo
(Serbian Chemical Society, 2007)
A prototype of a solid fuel thermo-accumulating furnace has been developed. In order to achieve a higher combustion efficiency, a Pt/Al2O3 catalyst in the form of 3 ± 0.3 mm spheres was applied, which enabled further ...
