Phase composition of Bi2O3 specimens doped with Ti, Zr and Hf
(Belgrade : Serbian Chemical Society, 2012)
Powder mixtures of α-Bi2O3 containing 2, 5 and 10 mole % of TiO2, ZrO2 or HfO2 were homogenized, heated at 820ºC for 24 h and quenched in air. X-ray powder diffraction technique was used to characterize the prepared samples. ...
The current distribution in an electrochemical cell. Part VII. Concuding remarks
(Serbian Chemical Society, 2002)
A new method for the determination of the ability of an electrolyte to distrubute uniformly current density in an electrochemical cell is proposed. It is based on the comparison of the current in cells in which the electrode ...
Metallic ion release from biocompatible cobalt-based alloy / Otpuštanje metalnih jona iz biokompatibilne legure kobalta
(Association of the Chemical Engineers of Serbia, 2014)
Metallic biomaterials, which are mainly used for the damaged hard tissue replacements, are materials with high strength, excellent toughness and good wear resistance. The disadvantages of metals as implant materials are ...
Application of the residual strength degradation model to carbon-epoxy composite
(Consultants Bureau/Springer, New York, 2008)
A residual strength degradation model for two orientations of fibers of carbon-epoxy composite is proposed. The model is constructed on the basis of an analysis of a gradual decrease in the residual strength of the composite ...
Numerical simulation of titanium alloy hip replacement implants behaviour under static and dynamic loads / Numerička simulacija implantata kuka od legure titanijuma pod statičkim i dinamičkim opterećenjima
(Savez hemijskih inženjera Srbije, 2023)
This paper presents development of numerical models for simulation of the behaviour of titanium alloy hip implants under static and dynamic loads, which is a part of extensive research involving the structural integrity ...
Određivanje efektivnog koeficijenta difuzije prilikom sušenja uzoraka od gline / Calculation of the effective diffusion coefficient during the drying of clay samples
(Srpsko hemijsko društvo, Beograd, 2012)
Cilj ovog rada je da se na primeru dve opekarske gline sa različitih lokaliteta odredi efektivni koeficijenat difuzije na osnovu eksperimentalno snimljenih krivih sušenja. Razvijen je metod i napravljena su dva kompjuterska ...
Thermal stability and degradation of Co(II), Cd(II), and Zn(II) complexes with N-benzyloxycarbonylglycinato ligand
(Springer, Dordrecht, 2010)
Thermal behavior of Co(II), Cd(II), and Zn(II) complexes with N-benzyloxycarbonylglycinato ligand was investigated using the results of TG, DSC and DTG analysis obtained at different heating rates (2.5 to 30 A degrees C ...
Synthesizing a new type of mullite lining
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2013)
Various possibilities for developing new mullite-based refractory linings that can be applied in a casting process were investigated and are presented in this paper. An optimization of the refractory-lining composition ...
Graphene Based Composite Hydrogel for Biomedical Applications
(Croatian Chemical Soc, Zagreb, 2017)
In this work, composite hydrogel consisting of poly(vinyl alcohol), graphene and silver nanoparticles, (Ag/PVA/Gr), was prepared by the immobilization of silver nanoparticles (AgNPs) in PVA/Gr hydrogel matrix in two steps. ...
Numerical and analytical modeling of elastic-plastic fracture mechanics parameters
(8th Conference of the Yugoslav Materials Research Society, 2007)
Structural integrity and service reliability depend on the fracture resistance of a material. Cracks in the material are the locations of stress concentration, and elastic-plastic deformation can occur causing the development ...
