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 ...
Technologically Sustainable Route for Metals Valorization from Jarosite-PbAg Sludge
(Minerals, 2021)
By-products from zinc hydrometallurgy are classified as hazardous waste with strong leaching toxicities. Even though numerous research papers are dedicated to valorizing valuable metals in it, the primary management route ...
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 ...
The analysis of forming PVB-SiO2 nanocomposite fibers by the electrospinning process / Analiza formiranja PVB-SiO2 nanokompozitnih vlakana pomoću elektrospining procesa
(Vojnotehnički institut, Beograd, 2011)
The poly (vinyl butyral)-silica (PVB-SiO2) nanofibers were obtained by the electrospinning process. The experiments were carried out with PVB solution in concentration of 10 wt.% where ethanol was used as the solvent. The ...

Conceptual design for treatment of mining and metallurgical wastewaters which contains arsenic and antimony
(Association of Metallurgical Engineers of Serbia, 2012)
This paper presents a preliminary design for treatment of mining and metallurgical wastewaters (MMW) from the basin of antimony 'Zajača', which contains high concentrations of arsenic and antimony. MMW have been investigated ...
The impact of manufacturing process on the content of hard triglycerides, hardness and thermal properties of milk chocolate
(Savez hemijskih inženjera, Beograd, 2012)
The rheological and physical properties of the chocolate mass depend on the ingredient composition as well as the manufacturing process. For the purpose of this work, a milk chocolate mass of identical composition and raw ...
