Microindentation hardness testing of different composite systems with thin electrodeposited nickel and copper films
(Belgrade : Military Technical Institute, 2012)
Thin Ni and Cu films with fine-grained structures have been electrodeposited from self-made sulphamate-based and sulphate-based electrolytes, respectively. DC electrodeposition of Ni films was performed on single crystal ...
THE EFFECT OF ENCAPSULATED AMOUNT OF CAFFEINE ON THE MECHANISM OF ITS RELEASE FROM HYDROGELS BASED ON POLY(METHACRYLIC ACID) AND CASEIN
(University of Szeged, 2022)
Researchers are making everyday efforts to develop new drugs or improve present ones in order
to enhance therapies of various diseases, especially serious ones like cancer. Drug delivery
systems (DDS) are one of the ...
Pretreatment of used vegetable oil using CaO and CaO-ZnO for biodiesel production
(Czech Society of Chemical Engineering, 2014)
Enzymatic Synthesis of Aliphatic Esters of Phenolic Acids and Evaluation of Their Antioxidant Properties
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
The esterification activity of the commercial immobilized lipase CALB towards cinnamic acids and its derivative has been studied. Using cinnamic acid as substrate, the reaction rate constants (1.95 h-1 mM-1 for ethanol and ...
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 ...
Dekolorizacija antrahinonskih boja peroksidazom iz rena imobilisanom na kaolin
(Beograd, Srpsko hemijsko društvo, 2014)
Antrahinonske boje su veoma značajne za tekstilnu industriju i, odmah nakon azo boja, imaju najveću primenu. Nažalost, kao i azo boje, i antrahinonske boje predstavljaju ozbiljan problem zagađenja životne sredine. Većina ...
Effect of substrate type on microhardness of multilayer thin film composite system
(Belgrade : Military Technical Institute, 2014)
Thin metallic multilayer films consisting of nanometer layer thickness deposited on different substrates have shown promising mechanical, electrical and magnetical properties, especially for applications in fabrication of ...
Design of Multi-pressure Organic Rankine Cycles for Waste Heat Recovery in Site Utility Systems
(Elsevier Science Bv, Amsterdam, 2014)
This work addresses the design of Organic Rankine Cycle (ORC) processes used for power generation from low-grade heat available in site utility systems. The Exergy Composite Curves approach is used within a systemic ...
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 ...
