Bray–Liebhafsky oscillatory reaction in a continuous-flow stirred tank reactor as the matrix system for determination of tyrosine
(Springer, 2022)
A kinetic method for the determination of l-tyrosine (Tyr) by analyte pulse perturbation, caused by different amounts of Tyr, in the Bray–Liebhafsky (BL) oscillatory reaction realized in a continuous-flow stirred tank ...
Oscillatory carbonylation of poly(ethylene glycol)methyl ether acetylene. Improved model of reaction mechanism
(Springer, 2022)
The study presents a mathematical model of Bruk Temkin-Gorodsky Novakovic (BT-GN) reaction system employing palladium-catalyzed oscillatory carbonylation reaction of mono alkyne-terminated poly(ethylene glycol) methyl ...
Chemical profile of Nepeta cataria L. var. citriodora (Becker) essential oil and in vitro evaluation of biological activities
(Lublin : Uniwersytetu Przyrodniczego Lublin, 2022)
Essential oil (EO) obtained by hydrodistillation in a Clevenger-type apparatus from aerial parts of Nepeta cataria L. var. citriodora (Becker), cultivated in Serbia was subjected to gas chromatography-mass spectroscopy ...
Ultra wideband bandpass filters with specified relative bandwidth
(Berlin : Walter de Gruyter GmbH, 2022)
Algorithm for the realization of the broad range of values of wide relative bandwidth (RBW) bandpass filter is introduced. Algorithm is based on periodic ideal cells each with short-ended stub. Theory is developed for a ...
Heat transfer by liquid convection in particulate fluidized beds / Пренос топлоте конвективним механизмом у партикулативно флуидизованом слоју
(Belgrade : Serbian Chemical Society, 2022)
In this work the theoretical model for heat transfer from a wall to aliquid-solid fluidized bed by liquid convective mechanism has been proposed.The model is based on thickness of boundary layer and film theory. The ...
QSRR model for predicting retention indices of geraniol chemotype of Thymus serpyllum essential oil
(Taylor & Francis, 2020)
A total of 26 experimentally obtained retention indices on a logarithmic scale (log RI) from
Thymus serpyllum essential oil were used to build a robust predictive model. The selected descriptors were
used as inputs of ...
The Application of Alumina for Electroanalytical Determination of Gallic Acid
(Springer, 2023)
A novel and simple electrochemical sensor for the determination of gallic acid is presented. The alumina sample was characterized by X-ray diffraction, FTIR, and particle size distribution analysis. The carbon paste electrode ...
Hardness and corrosion resistance of Zn−Mn/Al2O3 composite coatings produced by electrochemical deposition
(National Institute of Science Communication and Policy Research, 2022)
The aim of this study is development and characterization of the novel Zn-Mn/Al2O3 composite coatings. The coatings
were electrodeposited with constant current density on steel, from chloride solution, without any ...
Energy and emission properties of burley tobacco stalk briquettes and its combinations with other biomass as promising replacement for coal / Energetska i emisijska svojstva briketa od stabljika berlej duhana i njihovih kombinacija sa drugom biomasom kao obećavajuća zamjena za ugljen
(Walter de Gruyter GmbH, 2023)
As a tobacco producer, Serbia has to deal with large amounts of leftover tobacco stalks after harvesting. One option for this type of biomass is to burn it, but burning is not encouraged in Serbia, since the levels of its ...
Prediction of thermal and mechanical properties of acrylate-based composites using artificial neural network modeling / Predviđanje termičkih i mehaničkih svojstava kompozita na bazi akrilata korišćenjem modela veštačke neuronske mreže
(Association of Chemical Engineers of Serbia, 2023)
Poly(methyl methacrylate) (PMMA) has a broad spectrum of uses, especially in medical applications. The role of fine-grained alumina particles of PMMA composites was investigated in this study. The composites were based on ...
