Waste hemp and flax fibers and cotton and cotton/polyester yarns for removal of methylene blue from wastewater: Comparative study of adsorption properties / ОТПАДНА ВЛАКНА КОНОПЉЕ И ЛАНА И ПРЕЂЕ ПАМУКА И ПАМУК/ПОЛИЕСТЕРА ЗА УКЛАЊАЊЕ МЕТИЛЕНСКО ПЛАВОГ ИЗ ОТПАДНЕ ВОДЕ: УПОРЕДНА АНАЛИЗА АДСОРПЦИОНИХ КАРАКТЕРИСТИКА
(Serbian Chemical Society, 2023)
Waste hemp and flax fibers, and cotton and cotton/polyester yarns, available in large quantities from the textile industry, were used as cheap and effective sorbents for the removal of methylene blue from wastewater. Waste ...
Optimization of the extraction of antioxidants from stinging nettle leaf using response surface methodology
(Macedonian Journal of Chemistry and Chemical Engineering, 2022)
The aim of this study was to optimize the parameters for the extraction of total flavonoids from stinging nettle leaf. Comparison of the effects of different solvents on total flavonoid content showed that, regardless of ...
AERMOD air dispersion modeling and health risks of gas and oil fueled heating plant emissions
(VINČA Institute of Nuclear Sciences, 2023)
A significant part of the population in Serbia relies on central heating systems during
the winter months, with around fifty heating plants in operation across the country.
Common fuels used in these plants primarily ...
To Professor Petar Pfendt, In calidum, et plurium retributivus memoriae: FTIR-ATR analysis of post stamps of the Principality of Serbia issued in 1866 and 1868 and their forgeries
(Journal of the Serbian Chemical Society, 2022)
In order to further define the potential use of FTIR-ATR spectroscopy, as a non-destructive and reliable technique, for the analysis of the characteristics of post stamps, certified originals of the Principality of Serbia ...
Mass transfer in inverse fluidized beds / Prenos mase u inverzno fluidizovanom sloju
(Serbian Chemical Society, 2023)
In this work, the coefficient of fluid-wall mass transfer in an inverse fluidized bed was determined using the adsorption method. The experiments were carried out in a column with a diameter of 45 mm with spherical and ...
Thermo-mechanical analysis of linear welding stage in friction stir welding Influence of Welding Parameters
(VINČA Institute of Nuclear Sciences, 2022)
The influence of friction stir welding parameters on thermo-mechanical behavior of the material during welding is analyzed. An aluminum alloy is considered (Al 2024 T351), and different rotating and welding speeds are ...
Microstructure, hardness and fracture resistance of P235TR1 seam steel pipes of different diameters / Otpornost prema lomu, tvrdoća i mikrostruktura šavnih cevi različitog prečnika izrađenih od čelika P235TR1
(Association of the Chemical Engineers of Serbia, 2023)
Steel pipelines in industrial plants consist of different elements, including seamless and/or welded (seam) pipes. Properties of welded pipes, including their fracture behaviour, depend on the characteristics of both, the ...
INFLUENCE OF ELECTRODEPOSITION REGIME AND Sn:Pd RATIOS IN Sn-Pd ELECTROCATALYSTS ON ETHANOL OXIDATION REACTION / ВЛИЈАНИЕ НА РЕЖИМОТ НА ЕЛЕКТРОДЕПОЗИЦИЈАТА И НА ОДНОСИТЕ НА Sn:Pd ВО Sn-Pd-ЕЛЕКТРОКАТАЛИЗАТОРИТЕ ВРЗ ОКСИДАЦИЈАТА НА ЕТАНОЛОТ
(Society of Chemists and Technologists of Macedonia, 2023)
A series of bimetallic Sn-Pd catalysts were prepared by a template-free two step electrodeposition method. According to this method, Sn was electrodeposited firstly in potentiostatic or galvanostatic regime on Cu electrodes ...
INFLUENCE OF GASEOUS LASER IN CONTINUOUS-WAVE AND PULSE REGIMES ON BIOMATERIAL CHARACTERISTICS / УТИЦАЈ ГАСНИХ ЛАСЕРА У КОНТИНУАЛНОМ И ИМПУЛСНОМ РЕЖИМУ НА КАРАКТЕРИСТИКЕ БИОМАТЕРИЈАЛА
(Vinca Inst Nuclear Sci, 2023)
Aromatic plants and laser beam wavelength in the red range of visible spectra (623.8 nm), most commonly used for treating plant species, were selected. As there is not much information in the references, it is necessary ...
Overpotential controls the morphology of electrolytically produced copper dendritic forms / Пренапетост контролише морфологију електролитички произведених дендритичних форми бакра
(Belgrade : Serbian Chemical Society, 2019)
The morphologies of copper dendritic forms obtained in both potentiostatic and galvanostatic regimes of electrolysis with various amounts of the electricity were analyzed by the scanning electron microscopy (SEM) technique. ...
