Uticaj dopiranja niklom na optička, transportna i neka toplotna svojstva olovo-telurida
(Belgrade : University of belgrade, Faculty of Physics, 2005)
Ova teza je nastala kao rezultat ispitivanja optičkih, transportnih i pojedinih toplotnih svojstava legure PbTe(Ni). Korišćena su dva monokristalna uzorka sa različitim sadržajem Ni, prvi-0.29 % Ni i drugi-sa nešto većom ...

(8th World Biomaterials Congress 2008, WBC 2008; Amsterdam; Netherlands; 28 May 2008 - 1 June 2008, 2008)
Oxidation of metallic binder powder and its influence on mechanical properties metal-diamond composite
(Sendai : Japan Institute of Metals, 2000)
In this paper, the properties of metallic binders based on Co, Fe, bronze and their influence on mechanical characteristics of metallic binder-diamond composites, obtained by hot pressing of these powders, were analyzed. ...
Calcium Phosphate Ceramics Calcium Phosphate Ceramics - Bioresorbable Polymer Composite Biomaterials : from synthesis to applications : (1999-2007)
(Belgrade : Institute of Technical Science of SASA, 2007)
In the past several years, the accent of a number of scientific researches in the countries of the European Union, USA and Japan was focused on the field of biomaterials. Having the direct influence on the quality and ...
Investigation of ion-beam modified silicon by photoacoustic method
Thermal, elastic and electronic transport properties of ion-modified silicon samples were investigated by a photoacoustic frequency transmission technique. The experimental photoacoustic data vs the modulating frequency ...
Influence of the HAp ratio on the thermodynamic and kinetic parameters of PDMS/HAp composites cross-linking
(Contemporary Studies in Advanced Materials and Processes, 4th Yugoslav-Materials-Research-Society Conference, Sep 10-14, 2001, Herceg Novi, Yugoslavia, 2003)
Injectable and gas-permeable composite cements, polydimethylsiloxane/hydroxyapatite (PDMS/HAp), were synthesized using bi-component polysiloxane precursors (RTV-A and RTV-B), which react by hydrosilylation, and different ...
Structural and magnetic characterization of LiMn1.825Cr0.175O4 spinel obtained by ultrasonic spray pyrolysis
(Materials Research Bulletin, 2007)
Quaternary spinel oxide LiMn1.825Cr0.175O4 Powder was synthesized by using an ultrasonic spray pyrolysis method, without additional annealing. The crystal structure of the as-prepared powder was revealed by X-ray powder ...
Ground-state magnetism of chromium-substituted LiMn2O4 spinel
(Journal of Magnetism and Magnetic Materials, 2008)
Comparative crystal structure and magnetic properties studies have been conducted on quaternary powder spinel samples LiMn1.82Cr0.18O4 obtained by two different synthesis methods, glycine-nitrate (GN) and ultrasonic ...
Dielectric properties of BaTiO3 doped with Er203 and Yb203 based on intergranular contacts model
(Hoboken, NJ : John Wiley & Sons, 2009)
Taking into account that microstructure properties of barium-titanate based materials, expressed in grain boundary contacts, are of basic importance for electric properties of these material, in this study, the model of ...
Precursor particle size as the key parameter for isothermal tuning of morphology from nanofibers to nanotubes in the Na2-xHxTi nO2n+1 system through hydrothermal alkali treatment of rutile mineral sand
(Washington : American Chemical Society, 2009)
Morphology control in the (Na,H)2TinO2n+1 system has been achieved by introducing particle size as the key parameter during hydrothermal synthesis. The process is applied for the synthesis of TiO2-based nanofibers and ...
