Enzymatic synthesis of phenolic acid esters. / Enzimska proizvodnja estara fenolnih kiselina
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2016)
As secondary plant metabolites phenolic acids are common components of daily human diet. It is well established that these compounds have several physiological activities, amongst which the antioxidant activity is the most ...
Thermal properties of poly(urethane-ester-siloxane)s based on hyperbranched polyester
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Novel polyurethanes (PUs) were synthesized using hydroxy-terminated hyperbranched polyester (BH-20) and 4,4'-methylenediphenyl diisocyanate (MDI) as hard segments and hydroxy-terminated ethylene oxide-poly(dimethylsiloxa ...
Uticaj akumulativnog spajanja valjanjem (ARB) i konvencionalnog valjanja (CR) na korozionu stabilnost AA5083 legure / Influence of accumulative roll bonding (ARB) and conventional cold rolling (CR) on the corrosion stability of AA5083 alloy sheets
(Beograd : Srpsko hemijsko društvo, 2018)
Ispitivan je uticaj stepena i načina deformacije na korozionu stabilnost legure AA5083 koja
je procesirana konvencionalnim valjanjem (CR) i akumulativnim spajanjem valjanjem (ARB).
Koroziona stabilnost je praćena standardnim ...
Prediction and fuzzy synthetic optimization of process parameters in heavy clay brick production
(Elsevier Sci Ltd, Oxford, 2013)
Many factors influence final clay brick properties, since the raw materials used are highly heterogeneous. Statistical analysis is rarely used, according to literature, but it would improve understanding of the overall ...

The effect of boron incorporation on the structure and properties of glassy carbon
(Elsevier Ltd., 2011)
Boron was introduced into glassy carbon by chemical modification and by irradiating the precursor polymer with boron ions. Using chemical modification, a polymer with uniform distribution of boron in the bulk was obtained, ...
The evolution of hydrogen from proton irradiated glassy carbon
(Elsevier B.V., 2011)
Glassy carbon was irradiated with 15 key H(+) ion beam. It was observed that the implanted hydrogen is unstable in material and evolves as H, H(2) and H(2)O. Post-irradiation evolution of H, H(2) and H(2)O from proton ...
The infuence of starch hydrophilization on the mechanical properties of the biodegradable starch/EAA composites
(Lisbon : Instituto Superior Tecnico, 2019)
The aim of this study is to investigate the infuence of chemically modifed native starch on the
mechanical properties of composite materials. The starch (S) was modifed by diisopropyl D-tartarate (DIPT), ricinoleic acid ...
Influence of crack length on ductile fracture initiation in welded joints with one and two weld metals
(Trans Tech Publications Ltd, Durnten-Zurich, 2011)
Among various micromechanical models for ductile fracture analysis using local approach, those based on the Gurson plastic flow criterion have been intensively developed in the past three decades. However, their application ...
