An alternative route for valorization of valuable metals from jarosite residue / Alternativna metoda za valorizaciju vrednih metala iz jarosit ostatka
(Savez inženjera i tehničara Srbije, Beograd, 2019)
This paper aims to consider the treatment of jarosite residue using a different reducing agents, aluminum, magnesium, and carbon. The jarosite residue is not standard-it contains higher amounts of Pb and Ag, as well as in, ...
Swelling kinetics and impregnation of PLA with thymol under supercritical CO2 conditions / Kinetika bubrenja PLA i njegova impregnacija timolom upotrebom natkritičnog uglenik(IV)-oksida
(Savez inženjera i tehničara Srbije, Beograd, 2016)
The present work was aimed to study swelling kinetics of polylactic acid (PLA) and its impregnation with thymol in supercritical carbon dioxide (scCO2) medium. The influences of temperature and soaking time on the swelling ...
Merenje vibracija mrežom bežičnih senzora
(Savez inženjera i tehničara Srbije, Beograd, 2012)
Nedestruktivno praćenje stanja građevinskih objekata se bazira na merenju vibracija objekata pri dinamičkim ispitivanjima ili u toku njihove eksploatacije. U ovu svrhu se sve više koriste mreže bežičnih senzora koje čine ...
