Microelectronics miniaturization and fractal electronic frontiers
(Belgrade : Serbian Ceramic Society, 2013)
The intergrain ceramic structures are very complex and difficult to describe by using traditional analytical methods. In this study, in order to establish grain shapes of sintered ceramics, new approach on correlation ...
Far-infrared spectroscopy of PbTe doped with iron
(Belgrade : Serbian Chemical Society, 2002)
Far infrared reflection spectra, at room and liquid nitrogen temperature, of PbTe single crystals doped with iron are presented. Plasma minima were observed at about 160 cm–1 and 180 cm–1 for room and liquid nitrogen ...
Rare earth dual-doped multifunctional hydroxyapatite particles for potential application in preventive medicine
(2018)
Composite biomaterials based on nano hydroxyapatite (HAp) are the subject of numerous studies in reconstructive medicine. Multifunctional and nanoparticulate systems based on HAp and biodegradable polymers are successfully ...
ZnO varistors prepared by direct mixing of constituent phases
(Sendai : Japan Institute of Metals, 2000)
ZnO varistors with non-linearity coefficients reaching 50 and low values of the leakage current (approximately 0.01 A/m2), were obtained by a method referred to as `direct mixing of constituent phases'. The method is based ...
Low temperature sensitivity of upconversion emission in Y2O3:Yb,Tm and Y2O3:Yb,Ho powders
(2nd International Conference on Optical, Electronic and Electrical Materials, 5-7 August 2012, Shanghai, China, 2012)
In recent years trivalent rare earth doped materials have received significant attention for optical temperature sensors. In these materials ratio of fluorescence emissions from different energy levels exhibit strong ...
BaTiO3 – ceramics and Fractal Microstructure Analyses
(Belgrade : Serbian Ceramic Society, 2014)
Ceramics grain structure is difficult to describe by using traditional analytical methods based on Euclidean geometry. Using the fractal geometric/analytic methods instead, the new approach is offered in this paper. There ...
Thermoluminescence from europium doped gadolinium oxide aerosols
(2007)
Poster presented at the International Roundtable on Advanced Wide Band Gap Materials for Radiation Detectors - MATRAD 2007, June 17 till June 20, 2007 in Sinaia, Romania
Microstructure and EDS Contact Surfaces Characterization for Statistical Analysis of Doped BaTiO3-Ceramics
(Belgrade : Serbian Ceramic Society, 2012)
Barium-titanate based ceramics belongs to one of very important group of functional ceramics that can be used on a large scale of applications. The properties of BaTiO3 based ceramics are fundamentally correlated with grain ...
Dense spherical rare oxide particles synthesis via spray pyrolysis of polymeric precursor solution
(Belgrade : Institute of Technical Sciences of SASA, 2010)
Europium-doped (Y0.5Gd0.5)2O3 phosphor powder is synthesized via spray pyrolysis of polymeric precursor solution obtained by dissolving the stoichiometric amount of corresponding metal nitrates in ethylenediaminetetraacetic ...
Synthesis and characterization of bioactive glass doped with lithium and strontium ions
(Belgrade : Institute of Technical Sciences of SASA, 2018)
Bioactive glasses have been used for over three decades in biomedical applications owing to high bioactivity, biocompatibility, as well as the possibility to stimulate regeneration of the bone. The aim of this work was to ...
