Modeling of kinetics of pertechnetate removal by amino-functionalized glycidyl methacrylate copolymer
(Springer Verlag, 2012)
Technetium-99 comprises a significant health risk, since edible plants can bioaccumulate and convert it to more lipophilic species that cannot be excreted through urine. Batch kinetics of pertechnetate removal from aqueous ...
Speciation of Sr-90 and other metal cations in artificially contaminated soils: the influence of bone sorbent addition
(Springer Heidelberg, Heidelberg, 2013)
The influence of bone sorbent addition onto distribution of Sr-90 in artificially contaminated soil was preliminary studied to assess the possibility of biogenic apatite utilization for reduction of Sr-90 mobility and ...
The Galvanostatic Reduction on Modified Platinum Electrode and Determination of Trinitrotoluene in Neutral Solution
(Esg, Belgrade, 2013)
The study of the electrochemical reduction on acetonitrile modified platinum electrode and determination of trinitrotoluene (TNT) in neutral solution by simple galvanostatic technique is presented here. The obtained ...
The electrochemical behavior of PtRu- and Pt-modified zeolite X in alkaline solution
(Springer, New York, 2013)
Zeolite NaX was modified by Pt and Pt/Ru nanodispersed metallic clusters. The procedure of impregnation with acetylacetonate salt/acetone solution was applied. Scanning electron microscope analysis confirmed partial zeolite ...
Characterisation of New Bacillus circulans Strain Isolated from Oil Shale
(Croatia : University of Zagreb, Faculty of Food Technology and Biotechnology, 2012)
A new strain of Bacillus sp. was obtained during experiments of oil shale demineralization, which were carried out in order to get 'pure' organic matter (kerogen). The demineralization efficiency of newly isolated strain ...
Configurational, LFDFT and NBO analysis of chromium(III) complexes of edta-type ligands
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
A new hexadentate chromium(III) complex, Na[Cr(1,3-pd3ap)]center dot 3H(2)O, containing an unsymmetrical edta-type ligand, the 1,3-propanediamine-N,N,N'-triacetate-N'-3-propionate ion (1,3-pd3ap), has been prepared, ...
Mechanistic investigation and DFT calculation of the new reaction between S-methylisothiosemicarbazide and methyl acetoacetate
(Springer/Plenum Publishers, New York, 2013)
A study on the synthesis and mechanistical aspects of formation of 3-methyl-5-oxo-3-pyrazolin-1-carboxamide (MOPC) starting from S-methylisothiosemicarbazide hydrogen iodide and methyl acetoacetate was performed. In the ...
Synthesis, characterization, and antifungal activity of nystatingum arabic conjugates
(Wiley-Blackwell, Malden, 2013)
Nystatin, a polyene tetraene antibiotic widely used in the treatment of mycoses, was coupled with oxidized polysaccharide gum Arabic, by forming Schiff base structures between amine groups of antibiotics and aldehyde groups ...
Halogen bonding in complexes of proteins and non-natural amino acids
(Elsevier Sci Ltd, Oxford, 2013)
In this work, we have analyzed the influence of halogen bonding to the stability of 44 complexes of proteins and non-natural amino acids. Fluorine- and chlorine-containing non-natural amino acids are more prevalent in the ...
Fluctuations of the mass adsorbed on microcantilever sensor surface in liquid-phase chemical and biochemical detection
(Elsevier, 2012)
We present a simple mathematical model of adsorbed mass fluctuations in microcantilever sensors operating in liquids, taking into account the effects of the transfer process of analyte molecules from a solution to the ...
