ANN prediction of the efficiency of the decolourisation of organic dyes in wastewater by plasma needle
(Srpsko hemijsko društvo, Beograd, 2020)
In this paper, the results of decolourisation of Reactive Orange 16 (RO 16), Reactive Blue 19 (RB 19) and Direct Red 28 (DR 28) textile dyes in aqueous solution by plasma needle are presented. Treatment time, feed gas flow ...
Effects of waste sulfur content on properties of self-compacting concrete
(Consejo Superior Investigaciones Cientificas-Csic, Madrid, 2020)
Self-compacting concrete (SCC) contains fine mineral fillers such as limestone powder. The idea of this study was to partially replace limestone with waste sulfur since it is hydrophobic, insoluble in water and therefore ...
Thermo-responsive hydrogels based on poly(N-isopropyl- acrylamide) and hyaluronic acid cross-linked with nanoclays
(Srpsko hemijsko društvo, Beograd, 2020)
Semi-interpenetrating polymer networks (SIPN) based on thermo-responsive poly(N-isopropylacrylamide) (PNIPA) and water-soluble sodium salts of linear hyaluronic acid (Na-HA) were physically cross-linked with synthetic ...
Physical simulation of finish rolling of microalloyed steels in isothermal conditions / Simulacija završnog valjanja mikrolegiranog čelika u izotermalnim uslovima
(Association of the Chemical Engineers of Serbia, 2022)
The aim of this work was to establish a temperature of finish rolling stage of Nb/Ti microalloyed steel containing 0.06 wt.% C, 0.77 wt.% Mn, 0.039 wt.% Nb and 0.015 wt.% Ti, using physical simulation. Samples were subjected ...
Supercritical CO2 extraction of steroidal sapogenins from fenugreek (tngonella foenum-graecum l.) Seed
(Savez hemijskih inženjera, Beograd, 2020)
Supercritical CO2 extraction was applied on fenugreek (Trigonella foenum-graecum L., Fabaceae) seeds with the aim to define optimal process conditions to obtain the maximal extract yields content of steroidal sapogenins. ...
Origins of Polycyclic Aromatic Hydrocarbons in Sediments from the Danube and Sava Rivers and Their Tributaries in Serbia
(Hard, Olsztyn 5, 2020)
This study focussed on a comprehensive investigation on the state of pollution and identification of potential sources of contamination of some river sediments in Serbia by polycyclic aromatic hydrocarbons (PAHs), and is ...
On the Question of Energy and Power Potentials of the Electrode Materials in the Rechargeable Cells
(International Journal of Electrochemical Science, 2021)
The paper considers galvanostatic discharge of different rechargeable cells. In the first part of the paper, the useful mathematical equations for the calculation of voltage, capacity, capacitance, energy, and power is ...
A survey on the characterization and biological activity of isatin derivatives
(Srpsko hemijsko društvo, Beograd, 2020)
The derivatives of isatin have already been known to display a variety of biological activities. Therefore, the studies on their activity and its relation to structure have recently become a popular subject for investigation. ...
Transport properties and permeability of textile materials / Transportna svojstva i propustljivost tekstilnih materijala
(Savez hemijskih inženjera Srbije, 2023)
Heat and mass transfer through textile fabrics play a crucial role in achieving optimal thermal comfort perception by a person. The governing properties of textile fabrics by which they influence heat and mass transfer ...
Utilization of agro-industrial by-products as substrates for dextransucrase production by Leuconostoc mesenteroides T3: process optimization using response surface methodology
(Hemijska industrija, 2021)
Dextransucrase (DS) is a glucosyltransferase (E. C. 2.4.1.5) that catalyzes the transfer of glucosyl residues from sucrose to dextran polymer and liberates fructose. This enzyme isassociated with a wide application range ...
