Analytical modeling of activation procedure applied in α-alumina thermo-mechanical synthesis
(Elsevier, 2015)
The impact of the mechanical processing parameters on the alumina grain-size distribution affiliated characteristics and on the γ to α phase transformation rate was investigated. The moderation in the alumina samples ...
Generalized Lorentz model description of electrical, dielectric, conductive and magnetic processes two-time relaxations in BaTiO3 ceramics with constitutive relations
(Belgrade : Serbian Ceramic Society, 2017)
In this study, generalized Lorentz model is considered in the framework of dielectric, conductive and/or magnetic responses of materials. Beside positive temperature coefficient of resistivity (PTCR) materials (current ...
Proton conducting fluorinated polymer nanomembrane for fuel cell applications
(Torino, 2012)
Polymer electrolyte fuel cells (PEFC) gained a lot of interest in recent years as a potential solution for an eco-friendly energy. Proton exchage membranes (PEM) are one of the main components of PEFC and require mechanical ...
Kinetics of crystallization process of bulk metallic glass FeCrMoGaPCB prepared by cooper mold casting
(Belgrade : Materials Research Society of Serbia, 2012)
Iron based alloys are the family of bulk metallic glasses (BMG) with a very high melting temperature (Tm) and highest critical cooling rates (Rc~103K/s) necessary to suppress nucleation of crystals during the casting ...
Study of dielectric behavior and electrical properties of hematite α-Fe2O3 doped with Zn
(Belgrade : International Institute for the Science of Sintering, 2012)
The effects of Zn-doping on the dielectric behavior and electrical properties of bulk α-Fe2O3 have been studied. X-ray diffraction analysis revealed the presence of two phases in all samples: hematite and spinel ZnFe2O4, ...
Ka održivom modelu naučnih biblioteka...u Srbiji
(2015)
Kroz pregled i analizu kontinuiranih napora da se u dva beogradska naučna instituta uspostavi održiv model funkcionisanja biblioteke, u radu se pokazuje da je inteligentno korišćenje postojećih elektronskih servisa i ...
Scanning electron microscopy study of changes in nanoparticles surface under in vitro simulated physiological conditions
(Belgrade : Materials Research Society of Serbia, 2013)
In this study we observed the changes in surface of nanoparticles of two different nanomaterials, cobalt-substituted hydroxyapatite (CoHAp) and calcium phosphate/poly-(DLlactide-co-glycolide) (CP/PLGA) that occurred under ...
Low temperature effects on up-conversion emission of Er3+/Yb3+ co-doped Y2O3
(Belgrade : Agencija FORMAT, 2012)
Over the past years, Rare Earth (RE3+) ions doped materials have been attracted a great deal of interest due to the potential application for optical temperature sensors. Luminescence properties of these materials are ...
Interaction of nanoparticles and biological fluids
(Belgrade : Materials Research Society of Serbia, 2014)
Recent studies have shown that the behavior of nanoparticles in in vivo conditions is not solely dependant on their physical properties, such are size and shape. The surface of nanoparticles in biological fluids interacts ...
