Photochemical processes for removal of carbamate pesticides from water / Fotohemijski procesi za uklanjanje karbamatnih pesticida iz vode
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2019)
A large number of pesticide active ingredients have been registered and marketed for pest control purposes around the world. Most pesticides, including carbamates are resistant to chemical and natural photochemical ...
The characterization of ternary Zn-Ni-Co alloy coatings electrochemically deposited on steel from sulfate solution / Karakterizacija prevlaka trojnih legura Zn-Ni-Co na čeliku elektrolitički taloženih iz sulfatnog rastvora
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
In this work the electrochemical deposition of ternary Zn-Ni-Co alloy coatings on steel from sulfate, additive-free electrolyte, was investigated. The ratio of metal cations [Co2+]/[Ni2+] in the plating solution was analysed, ...
Modelling and optimization of surfactant sensor response characteristics for the use in surface water and wastewater analysis / Modelovanje i optimizovanje održivih karakteristika tenzidnog senzora za korišćenje pri analizi površinskih i otpadnih voda
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
The theoretical model of potentiometric titration curves of sodium dodecyl sulfate (anionic surfactant) was proposed and the response parameters of two surfactant sensors (commercial and self-made) were investigated. The ...
Effect of process parameters on the phase transformation kinetics in copper-based alloys and composites
(Metallurgical & Materials Engineering, 2020)
Copper-based alloys and composites, owing to their convenient properties, are being considered essential materials in various industries. Since copper possesses an ability to develop high corrosion resistance, putting it ...
The effect of cooling rate of slag from primary copper production in the valorization of copper in the flotation process
(Savez inženjera metalurgije Srbije, Beograd, 2015)
Technological procedure of slow cooling slag from primary copper production is applied in the purpose of copper recovery in the level of 98.5% to blister. This technological procedure is divided into two phases, first slow ...
Properties of cotton yarns after oxidation of potassium permanganate in an acidic environment / Svojstva pamučne pređe posle oksidacije kalijum-permanganatom u kiseloj sredini
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
The impact of nonselective cellulose oxidation (cotton fibre) by potassium permanganate in acidic environment, with or without additional treatment by sodium metabisulfite, on change of sorption (silver ions sorption), and ...
Investigation of copper(i) sulphide leaching in oxidative hydrochloric acid solution
(Savez inženjera metalurgije Srbije, Beograd, 2015)
Present work is focused on the copper (I) sulphide leaching with sodium chloride in hydrochloric acid solution and with introduction of gaseous oxygen. Chemical reactions of leaching and their thermodynamic probabilities ...
Simulation of velocity profile inside turbulent boundary layer
(Association of Metallurgical Engineers of Serbia, 2020)
The second-order differential equation with a general polynomial solution [1], is adapted for simulation of complex velocity profile inside the turbulent boundary layer. Consequently, the simulation strategy is suggested.
Indentation behaviour of 'soft film on hard substrate' composite system type / Ponašanje kompozitnih sistema tipa 'mek film na tvrdom supstratu' na testu utiskivanja
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
This investigation has been carried out in order to analyse and compare the hardness response of different composite systems of the same type, named 'soft film on hard substrate' composite system. Composite systems of mono- ...
CO tolerant Pt/Ru0.7Ti0.3O2 nanocatalyst for hydrogen oxidation reaction / Pt/Ru0,7Ti0,3O2 kao nanokatalizator za oksidaciju vodonika i njegova tolerancija na CO
(Engineering Society for Corrosion, Belgrade, Serbia, 2018)
The oxidation of pure H2 and H2/CO mixture (100 ppm CO) was investigated on Pt nanocatalyst supported on Ru0.7Ti0.3O2 (Pt /Ru0.7Ti0.3O2) by linear sweep voltammetry at a rotating disc electrode in 0.1 M HClO4. The results ...
