Biomarker and micropetrographic investigations of coal from the Krepoljin Brown Coal Basin Serbia
(Elsevier, 2013)
We investigated early diagenetic processes of the extractable organic matter from the Miocene freshwater sequence, which consists of coal fragments in clays, sandstones and shales alternating with continuous brown coal ...
The influence of water molecule coordination onto the water-aromatic interaction. Strong interactions of water coordinating to a metal ion
(Royal Soc Chemistry, Cambridge, 2013)
The interactions between water molecules (non-coordinating and coordinating) and aromatic rings were studied by analyzing data in the Cambridge Structural Database and by quantum chemical calculations. The results show the ...
Investigation of reaction between quercetin and Au(III) in acidic media: mechanism and identification of reaction products
(Royal Soc Chemistry, Cambridge, 2013)
The aim of the present paper was to investigate the reaction of quercetin, the flavonol very often used as a dietary supplement, with [AuCl4](-) ions. The reaction was studied spectrophotometrically using the equimolar ...
Characterization of PCBs from computers and mobile phones, and the proposal of newly developed materials for substitution of gold, lead and arsenic
(Springer Heidelberg, Heidelberg, 2013)
In this paper, we have analyzed parts of printed circuit board (PCB) and liquid crystal display (LCD) screens of mobile phones and computers, quantitative and qualitative chemical compositions of individual components, and ...
Evaluation of periodic processes with two modulated inputs based on nonlinear frequency response analysis. Case study: CSTR with modulation of the inlet concentration and flow-rate
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
In our previous work, a new, fast and easy, nonlinear frequency response method for analysing potential improvements of reactor performance by forced periodic operation was presented. This method, which is based on Volterra ...
Synthesis and characterization of bentonites rich in beidellite with incorporated Al or Al-Fe oxide pillars
(Elsevier, 2013)
Pillared clays (PILCs) based on bentonite clay from "Bogovina" (Serbia) were obtained using Al3+ and Fe3+ pillaring cations in different ratios. Thorough characterization of the starting material and PILCs was performed ...
Experimental Design in Formulation of Diazepam Nanoemulsions: Physicochemical and Pharmacokinetic Performances
(Wiley-Blackwell, Hoboken, 2013)
With the aid of experimental design, we developed and characterized nanoemulsions for parenteral drug delivery. Formulations containing a mixture of medium-chain triglycerides and soybean oil as oil phase, lecithin ...
Synthesis, characterization and biological activity of three square-planar complexes of Ni(II) with ethyl (2E)-2-[2-(diphenylphosphino) benzylidene]hydrazinecarboxylate and monodentate pseudohalides
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2013)
Three square-planar complexes of nickel(II) with the tridentate condensation derivative of 2-(diphenylphosphino)benzaldehyde and ethyl carbazate, and monodentate pseudohalides, have been synthesized. Their crystal structures ...
Preparation, characterization and photocatalytic activity of lanthanum and vanadium co-doped mesoporous TiO2 for azo-dye degradation
(Elsevier, 2013)
Titanium dioxide photocatalysts co-doped with lanthanum and vanadium were prepared by a facile microwave-assisted hydrothermal method and characterized by XRD, SEM, N-2 physisorption at 77 K and DRS. The characterization ...
