Microstructural morphology effects on fracture resistance and crack tip strain distribution in Ti-6Al-4V alloy for orthopedic implants
(Elsevier Sci Ltd, Oxford, 2014)
The effects of microstructural morphology on the fracture behavior of Ti-6Al-4V ELI (extra-low impurity) alloy in two different heat treatment conditions were examined. Alloy was solution treated above (beta ST) and below ...
Randomly oriented twin domains in electrodeposited silver dendrites
(Serbian Chemical Society, 2015)
Silver dendrites were prepared by electrochemical deposition. The structures of the Ag dendrites, the type of twins and their distribution were investigated by scanning electron microscopy (SEM), Z-contrast high angle ...
Ductile fracture resistance of the weld metal and heat affected zone in a HSLA steel welded joint
(19th European Conference on Fracture: Fracture Mechanics for Durability, Reliability and Safety, ECF 2012, 2012)
Ductile damage development in welded joints of high strength low alloyed (HSLA) steel NIOMOL 490K was examined experimentally and analyzed using the micromechanical approach. Single-edge notched bend (SENB) specimens, cut ...
Polymeric zinc complexes with 2,2 '-dipyridylamine and different benzenepolycarboxylato ligands: Synthesis, structure, characterization and antimicrobial activity
(Elsevier Ltd., 2016)
A series of new zinc complexes containing the 2,2'-dipyridylamine (dipya) ligand and anions of four benzenepolycarboxylic (BPC) acids, namely phthalic (H(2)pht), isophthalic (H(2)ipht), terephthalic (H(2)tpht) and pyromellitic ...
Controlled release of lipase from Candida rugosa loaded into hydrogels of N-isopropylacrylamide and itaconic acid
(Elsevier Science Bv, Amsterdam, 2012)
The series of poly(N-isopropylacrylamide-co-itaconic acid) hydrogels, with lipase from Candida rugosa as a model protein, were synthesized by free radical copolymerization. The composition of hydrogels was varied by monomers ...

The influence of the content of hemicelluloses on moisture sorption and effective relative dielectric permeability of alkali modified jute woven fabrics / Uticaj sadržaja hemiceluloza na sorpciju vlage i efektivnu relativnu dielektričnu propustljivost alkalno modifikovane tkanine od jute
(Beograd : Serbian Chemical Society, 2018)
In this investigation, the influence of alkali modification conditions on the chemical composition, i.e. content of hemicelluloses, moisture sorption and effective relative dielectric permeability of jute woven fabric were ...
CELULOZA: OD PRIRODE DO MATERIJALA VISOKIH PERFORMANSI / CELLULOSE: FROM NATURE TO HIGH PERFORMANCE MATERIALS
(Beograd : Tehnološko-metalurški fakultet Univerziteta, Centar celulozno-papirne, ambalažne i grafičke industrije Srbije, 2017)
Celuloza kao najzastupljeniji bioobnovljivi polimer dobija na značaju kako zbog ekonomskih razloga i mnogobrojnih mogućnosti primene, tako i zbog sve veće pažnje koju prirodnim resursima i održivom razvoju poklanjaju naučna ...
Uticaj parametara neselektivne oksidacije na sadržaj funkcionalnih grupa u celuloznim vlaknima / Influence of the nonselective oxidation conditions onto functional groups content in cellulose fibers
(Beograd : Srpsko hemijsko društvo, 2012)
In this paper, the influence of oxidation with hydrogen peroxide onto functional groups content in natural cellulose fibers was studied. Changes in fibers obtained at various modification conditions were evaluated by ...
Thermal stability of porcine pepsin influenced by Al(III) ion: DSC study
(Pleiades Publishing, 2011)
Differential scanning calorimetry (DCS) has been used to determine thermodynamic profile of pepsin and the in vitro effect of Al(III) ions. Thermograms of pepsin unfolding in the presence and absence of aluminum were used ...
