Scanning electron microscopy analysis of changes of hydroxiapatite/poly-l-lactide with different molecular weight of PLLA after intraperitoneal implantation
(Acta Veterinaria, 2016)
Implantation of a biomaterial is one of the important trends in solving the problem of bone tissue loss. Calcium hydroxiapatite (HAp), as the most representative bone component is a serious candidate for such implantations. ...
Synthesis and Characterization of Hydroxyapatite/Fullerenol Nanocomposites
(Journal of Nanoscience and Nanotechnology, 2015)
Fullerenols are polyhydroxylated, water soluble derivatives of fullerene C60, with potential application in medicine as diagnostic agents, antioxidants or nano drug carriers. This paper describes synthesis and physical ...
Influence of mechanochemical activation on the sintering of cordierite ceramics in the presence of Bi2O3 as a functional additive
(Elsevier, 2012)
Due to its outstanding electrical characteristics, such as the low temperature expansion coefficient, low dielectric constant and good mechanical properties, cordierite, 2MgO⋅2Al2O3⋅ 5SiO2, is a very attractive high-temperature ...
Magneto-optical effects in 1-xAsx with x=0.01: Comparison with topo- logical insulator Bi1-xSbx with x=0.20
(Weinheim : Wiley, 2014)
In this work, we explore possible topological insulating state in bismuth doped with arsenic Bi1-xAsx. Infrared and magneto-optical spectroscopy are employed to probe the electrodynamic response of Bi1-xAsx with x = 0.01, ...
The influence of compaction pressure on the density and electrical properties of cordierite-based ceramics
(Belgrade : International Institute for the Science of Sintering, 2015)
Due to its characteristics, cordierite, 2MgO·2Al2O3·5SiO2, is a high-temperature ceramic material of a great scientific interest. Mechanical activation of the starting mixtures containing 5.00 mass% TiO2 was performed in ...
Characterization of pressure-less sintered MgO-Al2O3-SiO2-TeO2 system
(Belgrade : Materials Research Society of Serbia, 2017)
In this study, sintering of two systems was investigated in parallel, pure cordierite 2MgO:2Al2O3:5SiO2, and cordierite with addition of 5 mass % TeO2. Green bodies were prepared from powder mixtures mechanically activated ...
Influence of mechanical activation on the MgO-Al2O3-SiO2 system with TeO2
(Belgrade : Materials Research Society of Serbia, 2016)
Cordierite 2MgO+2Al2O3+5SiO2 is frequently used ceramic material, that is commonly used as a carrier of electrical components due to its low dielectric constant (~ 5), and low temperature thermal expansion coefficient ...
The Rare-Earths influences on doped BaTiO3-Ceramics Microstructure and Electric Characteristics
(Belgrade : Serbian Ceramic Society, 2016)
The influence of rare-earth additive content on microstructure and electric properties of doped BaTiO3 ceramics is investigated. The concentration of Er2O3 and Yb2O3 in the doped samples range from 0.01 to 1.0at % . The ...
Chemical Analysis of Mortars of Archeological Samples form Mediana
(Belgrade : Serbian Ceramic Society, 2016)
The aim of this study was mineralogical and chemical analysis of mortar from the floor, ceiling and wall of Stibadium B, from the archaeological site of Mediana. ICP-OES and FTIR-spectroscopy were used to determine chemical ...
Biomaterijali
(Beograd : Institut tehničkih nauka Srpske akademije nauka i umetnosti; Društvo za istraživanje materijala, 2010)
Početak XXI veka nesumnjivo je obeležen interdisciplinarnim i multidisciplinarnim naporima istraživača u različitim oblastima nauke. Jedna od najizrazitijih tendencija ovog tipa uočava se u biomedicinskim istraživanjima, ...
