Thermal Resistance of Alkali Activated Binders Synthesized Using the Fly Ash and Steel Slag
(Belgrade : Materials Research Society of Serbia, 2015)
The thermal resistance of alkali-activated binders based on fly ash (FA), electric arc furnace slag (EAFS) and their FA/EAFS blends was assessed. Compressive strengths of samples before and after firing were measured. The ...
Periodically operated CSTRs with simultaneous modulation of feed concentration and flow-rate- Nonlinear frequency response approach
(10th European Congress of Chemical Engineering (ECCE 10), Nice, France, 2015)
Possible improvements of chemical reactor performance through periodic modulation of one or more inputs have been investigated for several decades. In our previous investigations we have introduced the nonlinear frequency ...
Delimično topljenje i centrifugiranje kao nova metoda pred-tretmana metaličnog granulata e-otpada: Preliminarni laboratorijski test
(Bor : Tehnički fakultet, 2012)
Ogromne količine otpada od električnih i elektronskih proizvoda (e-otpad) koje se u svetu
svakodnevno generišu ne prerađuju se na adekvatan način. Rast cena metala koji se beleži
poslednjih godina, glavni je razlog što ...
Assessment of the Composite Behavior of Different Ni/Cu Multilayer Composite Systems
(IEEE, New York, 2014)
Nickel and copper thin films were alternately electrodeposited from sulphamate and sulphate-based electrolytes respectively, on different substrates: polycrystalline cold rolled copper, single crystal (111)-oriented Si and ...
