Effect of tungsten carbide in carbon Pt catalyst support on electrochemical oxygen reduction in acid solution / Uticaj prisustva volfram-karbida u ugljeničnom nosaču Pt nanočestica na elektrohemijsku redukciju kiseonika u kiselom rastvoru
(Association of Chemical Engineers of Serbia, 2013)
Tungsten carbide was synthesized by calcination of carbon cryogel with embedded tungsten in a form of metatungstate. This material was used as a support for Pt nanoparticles. XRD pattern of W-C support indicated the presence ...
Adsorption of lipase from Candida rugosa on multi walled carbon nanotubes
(Korean Society of Industrial Engineering Chemistry, 2013)
In this work lipase from Candida rugosa was adsorbed on unmodified surface of multi walled carbon nanotubes (raw-MWCIsIT). The effects of immobilization time, initial enzyme concentration and buffer ionic strength on enzyme ...
Cation-pi interactions in high resolution protein-RNA complex crystal structures
(Elsevier Sci Ltd, Oxford, 2013)
In this work, we have analyzed the influence of cation-pi interactions to the stability of 59 high resolution protein-RNA complex crystal structures. The total number of Lys and Arg are similar in the dataset as well as ...
Tailoring the supercapacitive performances of noble metal oxides, porous carbons and their composites / Rasvetljavanje superkondenzatorskih odlika oksida plemenitih metala, poroznih ugljeničnih materijala i njihovih kompozita
(Serbian Chemical Society, 2013)
Porous electrochemical supercapacitive materials, as an important type of new-generation energy storage devices, require detailed analysis and knowledge of their capacitive performances under different charging/discharging ...
N-{[2-(4-Phenyl-piperazin-1-yl)-ethyl]-phenyl}-arylamides with Dopamine D-2 and 5-Hydroxytryptamine 5HT(1A) Activity: Synthesis, Testing, and Molecular Modeling
(Wiley-V C H Verlag Gmbh, Weinheim, 2013)
The ratio of affinities toward the dopamine D-2 and the 5-hydroxytryptamine 5-HT1A receptors is one of the important parameters that determine the efficiency of antipsychotic drugs. Here, we present the synthesis of ortho-, ...
Kinetics of sunflower and used vegetable oil methanolysis catalyzed by CaO center dot ZnO
(Elsevier Sci Ltd, Oxford, 2013)
The kinetics of heterogeneous methanolysis of sunflower oil and used vegetable oil were studied at different temperatures, ranging from 60 to 96 degrees C using CaO center dot ZnO as catalyst (2 wt% on the basis of oil) ...
Electrocatalytic properties of Pt-Bi electrodes towards the electro-oxidation of formic acid / Elektrokatalitička svojstva Pt-Bi elektroda u oksidaciji mravlje kiseline
(Serbian Chemical Society, 2013)
Formic acid oxidation was studied on two Pt-Bi catalysts, i.e., Pt2Bi and polycrystalline Pt modified by irreversible adsorbed Bi (Pt/Biirr) in order to establish the difference between the effects of Biirr and Bi in the ...
Effect of four lichen acids isolated from Hypogymnia physodes on viability of rat thymocytes
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Four lichen acids, physodalic acid (F1), physodic acid (F2), 3-hydroxyphysodic acid (F3), and isophysodic acid (F4), were isolated from Hypogymnia physodes methanol extract using preparative reversed-phase high performance ...
Energy-momentum dispersion relation of plasmarons in bilayer graphene
(Amer Physical Soc, College Pk, 2013)
The relation between the energy and momentum of plasmarons in bilayer graphene is investigated within the Overhauser approach, where the electron-plasmon interaction is described as a field theoretical problem. We find ...
Integer quantum Hall effect in single-layer graphene with tilted magnetic field
(Amer Inst Physics, Melville, 2013)
Analytical expression for the Hall conductivity sigma(yx) in graphene is derived in more general case, in which magnetic field is not perpendicular to the plane of the sample. The derivations were carried out using ...
