Review: The approaches for estimation of limit of detection for ICP-MS trace analysis of arsenic
(Talanta, 2012)
The analytical properties of an analytical method must be evaluated through validation protocols. Beside specificity and/or selectivity, linearity of calibration, repeatability and accuracy, the most important parameters ...
Voltammetric Investigation of Inclusion Complexes of the Selected Succinimides with beta-Cyclodextrin and (2-Hydroxypropyl)-beta-Cyclodextrin
(Slovensko Kemijsko Drustvo, Ljubljana, 2019)
The inclusion complexes of the selected, potentially biologically active, succinimides with beta-cyclodextrin (beta CD) and (2-hydroxypropyl)-beta-cyclodextrin (HP beta CD) were prepared. The formation of the inclusion ...
Influence of the structural changes on cavitation resistance of Al18SiCuMg alloy produced by rheocasting process / Uticaj strukturnih promena na kavitacionu otpornost Al18SiCuMg legure proizvedene reokasting procesom
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
The influence of stirring speeds of 1000 and 1500 r/min on the microstructure of Al18SiCuMg alloy was investigated. The smaller size of Si particles of rheocast sample obtained by higher cooling rate and higher stirring ...
Synthesis of CaO-SiO2 compounds and their testing as heterogeneous catalysts for transesterification of sunflower oil
(Elsevier Science Bv, Amsterdam, 2019)
The powder mixtures of calcium oxide (CaO) and silica gel (SiO2) in molar ratios of 1:1, 1.5:1, 2:1 and 3:1 were mechanochemically treated with the addition of water, and were subsequently calcined with a goal of synthesizing ...
A study of the barrier properties of polyethylene coated with a nanocellulose/magnetite composite film
(Srpsko hemijsko društvo, Beograd, 2016)
The morphological, thermal and barrier properties of low-density polyethylene/polycaprolactone-modified nanocellulose hybrid materials were investigated in this study. Nanocellulose/magnetite (NC-Fe3O4) nanocomposite and ...
Improved HER activity of Ni and stainless steel electrodes activated by NiCoMo ionic activator - A combined DFT and experimental study
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
In this paper we discussed various factors contributing to the improvement of hydrogen evolution reaction (HER) activity of Ni and stainless steel electrodes activated by in situ addition of NiCoMo activators, using a ...
Characterization and usefulness of corn cob as biosorbent for Pb2+, Cu2+ and Zn2+ ions removal from aqueous solutions / Karakterizacija i primena oklaska kukuruza za biosorpciju Pb2+, Cu2+ i Zn2+ jona iz vodenog rastvora
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
The objective of this study was to investigate corncob as biosorbent for heavy metals removal from aqueous solutions. All biosorption experiments were performed in batch system. The biosorbent were caracterized by thermal ...
Sepiolite functionalized with N-[3-( trimethoxysilyl)propyl]-ethylenediamine triacetic acid trisodium salt. Part II: Sorption of Ni2+ from aqueous solutions
(Srpsko hemijsko društvo, Beograd, 2016)
The sorption of Ni2+ on sepiolite functionalized by covalent grafting of N-[3-(trimethoxysilyl) propyl] ethylenediamine triacetic acid trisodium salt, MSEAS, was studied in batch experiments as a function of the initial ...
Cfd analysis and flow model reduction for surfactant production in helix reactor
(Savez hemijskih inženjera, Beograd, 2015)
Flow pattern analysis in a spiral Helix reactor is conducted, for the application in commercial surfactant production. Step change response curves (SCR) were obtained from numerical tracer experiments by three-dimensional ...
Vegetable oil as a feedstock for biodiesel synthesis
(Vegetable Oil: Properties, Uses and Benefits, 2016)
Limited reserves of fossil fuels as well as the growing concern for the environment, has led to a worldwide search for renewable energy sources, among which biodiesel, a mixture of fatty acid methyl esters (FAME), is one ...
