Infrared reflectance of single-crystal jarandolite, CaB3O4(OH)3
(Twickenham : Mineralogical Soc., 2007)
Polarized far- and mid-infrared reflectance spectra were measured at room temperature for the new mineral species jarandolite, CaB3O4(OH)(3), for the two principal directions. Thirty three vibration modes for (E) over right ...
Dielectric and ferroelectric properties of BaTi1-xSnxO3 multilayered ceramics
(Research Trends in Contemporary Materials Science, 8th Conference of the Yugoslav-Materials-Research-Society (Yu-MRS), Sep 04-08, 2006, Herceg Novi, Montenegro, 2007)
Multilayered BaTi1-xSnxO3 (BTS) ceramics with different Ti/Sn ratios were produced by pressing and sintering at 1420 degrees C for 2 hours. X-ray diffractometry, scanning electron microscopy and energy dispersive spectroscopy ...
Ispitivanje sinterovane cink-kalaj-oksidne keramike fotoakustičnom spektroskopijom
(Beograd : Savez hemijskih inženjera, 2007)
Prahovi ZnO i SnO2 pomešani u molamom odnosu 2:1 mehanički su aktivi- rani u planetamim mlinu sa kuglama u intervalu od 10 do 160 minuta. Do- bijene smeše presovane su i izotermski sinterovane na 1300 °C, dva sata. Uzorci ...
Preparation and Characterization of Poly(D,L-Lactide-co-Glycolide) Nanoparticles Containing Ascorbic Acid
(Hindawi, 2007)
This paper is covering new, simplistic method of obtaining the system for controlled delivery of the ascorbic acid. Copolymer poly (D,L-lactide-co-glycolide) (DLPLG) nanoparticles are produced using physical method with ...
Biphasic calcium phosphate coated with poly-d,l-lactide-co-glycolide biomaterial as a bone substitute
(Elsevier, 2007)
A calcium phosphate/poly-d,l-lactide-co-glycolide (BCP/DLPLG) composite biomaterial was synthesized in the shape of spherical granules (150–200 m) and nanostructured particles (30–40 nm) by an emulsification/evaporation ...
Comparison between different LiFePO4 synthesis routes
(Research Trends in Contemporary Materials Science, 8th Conference of the Yugoslav-Materials-Research-Society (Yu-MRS), Sep 04-08, 2006, Herceg Novi, Montenegro, 2007)
Olivine-type lithium iron phosphate (LiFePO4) powders were synthesized applying three different methods: solid state reaction at high temperature, ultrasonic spray pyrolysis, and sonochemical treatment. The samples were ...
Influence of Urea as Homogeneous Precipitation Agent on Sonochemical Hydroxyapatite Synthesis
(Zurich : Trans Tech Publications, 2007)
The main purpose of the present work was to investigate the influence of urea concentration on hydroxyapatite (HAp) synthesis. Calcium nitrate and ammoniumdihydrogenphosphate were used as Ca and P sources. A homogeneous ...
Aerosol synthesis and characterization of nanostructured particles of Y3Al5O12:Ce3+ and Y2O3:Eu3+
(Belgrade : Association of the Chemical Engineers of Serbia, 2007)
Nanostructured YAG:Ce3+ and Y2O3:Eu3+ were synthesized by low temperature (320°C) aerosol synthesis-LTAS and high temperature (900°C) aerosol synthesis-HTAS, respectively. The synthesis included aerosol generation from a ...
Gd2O3:Eu System: Structural Study of the Influence of Luminescence Center Concentration
(Zurich : Trans Tech Publications, 2007)
In this paper, the influence of the Eu3+ center concentration on the structural and morphological properties of the Gd2O3 system obtained by Spray Pyrolysis have been studied. The processing route includes aerosol formation ...
Effect of ageing on optical and thermal properties of YBa2Cu3O7–δ
(International Journal of Materials Research, 2007)
Photoacoustic phase and amplitude spectra of YBa 2 Cu 3 O 7 – δ samples synthesised 18 years ago were measured and numerically analysed. The value of thermal diffusivity obtained on the aged samples was lower than the ...
