GEOSPATIAL MAPPING OF ECOLOGICAL RISK FROM POTENTIALLY TOXIC ELEMENTS IN SOIL IN THE PANNONIAN-CARPATHIAN BORDER AREA SOUTH OF THE DANUBE
(Carpathian Association of Environment and Earth Sciences, 2022)
This study collected agricultural surface soil samples from 200 sites in the district of Braničevo, located in the Carpathian Mountains – Pannonian Basin south of the Danube River (Serbia). The main objective was to determine ...
Sorption of Cu2+ and Co2+ from aqueous solutions onto sepiolite: An equilibrium, kinetic and thermodynamic study / Sorpcija jona bakra i kobalta iz vodenih rastvora na sepiolitu, ispitivanje ravnoteže, kinetike i termodinamike sorpcije
(Serbian Chemical Society, Belgrade, 2011)
The efficiency of natural sepiolite for the removal of Cu2+ and Co2+ from aqueous solution was determined using the batch method. The sorption experiments were performed as a function of the initial metal concentration, ...
A new technological solution for the manufacture of a borer for iron notch opening at the blast furnace plant / Primena aluminotermijskog postupka izrade i zavarivanja vrha burgija koje se koriste za otvoranje visoke peći tokom ispusta gvožđa
(Institut za istrazivanja i projektovanja u privredi, 2004)
A new technology for the manufacture of a borer by alumino-thermal method, system design for performing alumino-thermal reaction, as well as required quality of termite steel, is disclosed in this paper. In addition to ...
Crack propagation in 3PB specimen made from welded joint
(1st Virtual European Conference on Fracture - Vecf1, 2020)
Crack propagation in 3PB specimen has been investigated experimentally by using Digital Image Correlation (DIC) technique. For this purpose, specimens were taken from butt welded plates, made of P460NL1 micro-alloyed steel. ...
Investigation of thermodynamic properties and phase equilibria in Ag-In-Sn system / Ispitivanje termodinamičkih veličina i faznih ravnoteža u sistemu Ag-In-Sn
(Savez inženjera i tehničara Srbije, Beograd, 2006)
Lead - free soldering became very popular in the whole world, because of high ecological demands in industry. Most of alternative alloys have high content of tin, and some of them are already used in electronic industry. ...
Hydrometallurgical process for extraction of metals from electronic waste, part II: Development of the processes for the recovery of copper from printed circuit boards (PCB)
(Savez inženjera metalurgije Srbije, Beograd, 2011)
Rapid technological development induces increase of generation of used electric and electronic equipment waste, causing a serious threat to the environment. Waste printed circuit boards (WPCBs), as the main component of ...
Possibilities of recycling of magnesium and magnesium alloys
(Savez inženjera metalurgije Srbije, Beograd, 2004)
In this paper are presented results of experimental investigation of processing of non oil-contaminated metal scrap based on magnesium and its alloys. These are the firs investigations of magnesium scrap recycling in Serbia ...
Corrosion Stability of Corrosion Products on an Archaeological Iron Artefact
(Alexandru Ioan Cuza University Publiching House Iasi-Romania, 2012)
A spearhead of archaeological and cultural significance has been found and analysed in
Serbia. In the corrosion products of the artefact, the dominant phases were goethite (α-
FeO(OH)) and magnetite (Fe3O4) whose presence ...
Hydrogenation of oil produced by naphtha steam pyrolysis: Determination of catalyst activity / Hidrogenovanje pirolitičkog ulja nastalog u procesu pirolize primarnog benzina - određivanje aktivnosti katalizatora
(Association of Chemical Engineers of Serbia, 2000)
Residual pyrolysis oil (RPO) produced as a by-product of naphtha steam pyrolysis was hydrogenated (160-280°C; 60 bar; trickle-bed reactor with Co-Mo/y-AlgOs) with the aim of suppressing the polymerization of the unsaturated ...
Conservation of the Archaeological Finds from Roman Period
(UNIVERSITY OF TIMISOARA, 2012)
A degree of preservation of iron artefacts depends on the type of underground environment and the type of
corrosion products formed on their surface. This paper analyses the conditions of an archaeological artefact made ...
