Hydrometallurgical recovery of tin and lead from waste printed circuit boards (wpcbs): limitations and opportunities
(Croatian Metallurgical Soc, Zagreb, 2016)
In this paper, possibility for selective Pb and Sn recovery, using three different solutions of NaOH, HCl and HNO3, from WPCBs containing low concentrations of Pb and Sn is presented. According to obtained results, over ...
Micromechanical model for fracture toughness prediction in Al-Zn-Mg-Cu alloy forgings
(Taylor & Francis Ltd, Abingdon, 2008)
An attempt has been made to model the plane-strain fracture toughness, KIc, in Al-Zn-Mg-Cu alloy forgings subjected to overageing. The proposed model, based on the multiple micromechanisms, reveals the quantitative relations ...
Decreasing of water absorptiveness of paper by coating nanofibrillated cellulose films
(Engineers Society for Corrosion, 2021)
Nanofibrillated films based on TEMPO-oxidized cotton linters were applied to reduce the hydrophilic properties of paper. For this purpose, aqueous dispersions of nanofibrillated cellulose of different composition: 1 and ...
Effect of material heterogeneity and constraint conditions on ductile fracture resistance of welded joint zones - Micromechanical assessment
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
The topic of this work is assessment of ductile fracture initiation and development in different zones of welded joint of a high strength low alloyed (HSLA) steel. A combined experimental-numerical procedure is applied for ...
Electrochemical properties of mixed WC and Pt-black powders / Elektrohemijska svojstva smeše prahova WC i Pt
(Serbian Chemical Society, Belgrade, 2008)
The electrochemical characteristics of a mixture of Pt-black and WC powders and its catalytic activity for methanol and formic acid oxidation were investigated in acid solution. XRD and AFM measurements revealed that the ...
Oxygen reduction on iron. Part III. An analysis of the rotating disk-ring electrode measurements in near neutral solutions
(Elsevier Science Sa, Lausanne, 1989)
The kinetics of oxygen reduction were studied on iron in borate and bicarbonate buffered solutions, pH 9.8, using the rotating disk-ring method. Under these conditions O2 reduction occurs both on the oxidized surface and ...
Optimization of galacto-oligosacharides synthesis using response surface methodology / Optimizacija sinteze galakto-oligosaharida pomoću metoda odzivnih površina
(Institute for Food Technology, Novi Sad, 2017)
Galacto-oligosaccharides (GOS) are important lactose-derived compounds, considered to be a prebiotics, based on abundant scientific evidence about their unique physical properties and physiological effects. This consequently ...
Modern encapsulation processes in food technology / Savremeni procesi inkapsulacije u tehnologiji hrane
(Društvo za ishranu Srbije, Beograd, 2014)
The encapsulation processes have been intensively studied in the recent years as possible alternative to conventional food technologies. Encapsulation of food active compounds is based on formation of protective layer(s) ...
