Comparative study of the phenolic composition of seeds from grapes cv cardinal and alphonse lavallee during last month of ripening
(Chiriotti Editori, 2012)
During the last month of ripening, the phenolic composition of seeds from two widely distributed table grapes, cv Cardinal and Alphonse Lavallee, was determined by HPLC/DAD/ESI/MS. Besides, the concentrations of nutrients ...
A new insight into the mechanism of lead electrodeposition: Ohmic-diffusion control of the electrodeposition process
(Elsevier, 2013)
A new insight into the mechanism of lead electrodeposition from nitrate solutions is presented by analysis of the polarization characteristics and by scanning electron microscopic (SEM) analysis of the surface morphology ...
Organochlorine pesticides in the Tisza River (Serbia): Distribution and risk assessment / Pesticidi u reci Tisi (Srbija) : Distribucija i procena rizika
(Serbia : Matica srpska, 2019)
Paper provided the systematic data on the distribution and risk assess¬ment status of organochlorine pesticides (OCPs) in sediment of the Tisza River (Serbia). The α-HCH, endrin ketone and methoxychlor are the most commonly ...
Synthesis, characterization and biological activities of N-heteroaromatic hydrazones and their complexes with Pd(II), Pt(II) and Cd(II)
(Springer, Dordrecht, 2010)
Condensation derivatives of ethyl hydrazinoacetate with 2-formylpyridine and quinoline-2-carboxaldehyde were synthesized. Pd(II), Pt(II) and Cd(II) complexes with the 2-formylpyridine derivative and a Cd(II) complex with ...
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 ...
Comparative Spectroscopic Characterization of the Basic and the Higher Fullerenes
(Taylor & Francis Inc, Philadelphia, 2013)
The basic C-60 and C-70, and the higher fullerenes, mainly C-76 and C-84, were extracted by original procedures, with p-xylene and the mixture of xylenes from the samples of initial carbon soot, produced in electrical arc. ...
Detection limit for an adsorption-based mercury sensor
(Elsevier, 2013)
A novel readout procedure for the determination of detection limit at an adsorption-based mercury sensor is described. The procedure is based on the evaluation of the initial voltage slope in time evolution of adsorbed ...
Calculation of the Jahn-Teller parameters with DFT / Izračunavanje Jan-Telerovih parametara primenom teorije funkcionala gustine
(Serbian Chemical Society, 2019)
In this review, we present Density Functional Theory (DFT) procedure to calculate the Jahn-Teller (JT) parameters in a non-empirical way, which does not depend on the system at hand. Moreover, the Intrinsic Distortion Path ...
Stereospecific ligands and their complexes. Part X: Synthesis, characterization and in vitro antitumoral activity of platinum(IV) complexes with O,O '-dialkyl-(S,S)-ethylenediamine-N,N '-di-2-(4-methyl)pentanoate ligands
(Elsevier Science Sa, Lausanne, 2012)
Synthesis of four new platinum(IV) complexes 1-4, with bidentate N,N'-ligand precursors O,O'-dialkyl esters (alkyl = ethyl, n-propyl, n-butyl and n-pentyl), of (S,S)-ethylenediamine-N,N'-di-2-(4-methyl)pentanoic acid ...
Decrease of free fatty acid content in vegetable oil using silica supported ferric sulfate catalyst
(Elsevier Sci Ltd, Oxford, 2012)
A difficulty of biodiesel synthesis based on alkaline catalysts obviously exists if free fatty acids (FFAs) content in vegetable oil is above 0.5 wt.%. In this study, the ferric sulfate supported on silica (Fe-2(SO4)(3)/SiO2) ...
