The synthesis - structure relationship in the ZnO-Cr2O3 system
(Belgrade : International Institute for the Science of Sintering, 2004)
In this work the development of the spinel phase in the ZnO-Cr2O3 system was discussed from the viewpoint of the synthesis-structure relationship. The nanostructure evolution in particles obtained either via solution-based ...
Aerosol synthesis of pure and Pt-doped ZnO particles using nitrate and pdda-Pt(IV) complex solutions
(Cambridge Univ Press, New York, 2005)
Pure and Pt-doped ZnO nanophase particles were synthesized by ultrasonic spray pyrolysis. The particles were obtained through the decomposition of zinc nitrate and with a newly developed Pt(IV) complex with 1,3 ...
Aerosol route in processing of nanostructured phosphor materials
(Novi Sad : University of Novi Sad, Faculty of Technology, 2010)
Among the methods currently used for nanophase processing, synthesis through dispersion phase (aerosol) enables generation of ultrafine powders with controlled stoichiometry. It represents a 'bottom-up' chemical approach ...
The effect of pH of the sodium hypochlorite on smear layer removal / Uticaj pH vrednosti rastvora natrijum-hipohlorita na uklanjanje razmaznog sloja
(Srpsko lekarsko društvo - Stomatološka sekcija, Beograd, 2010)
Introduction. Canal irrigation is an important segment of endodontic treatment. The aim of this study was to assess the efficacy of 0.5% NaOCl solutions of different pH values on smear layer removal. Material and Methods. ...
Microstructural and morphological analysis of nanostructured alumina particles synthesized at low temperature via aerosol route
(Elsevier BV, 2008)
Nanometer-sized particles (1–100 nm) are of considerable interest for a wide variety of applications, ranking from catalyst to luminescence ceramics, due to their unique and improved properties primarily determined by size, ...
Probabilistički proračun gubitka stabilnosti tankih panela pod dejstvom kombinovanog opterećenja / Probabilistic approach to buckling analysis of thin panels subject to combined loads
(Beograd : Vojnotehnički institut, 2010)
This paper gives the procedure for the reliability calculation of mechanical components and structures. The stability (buckling) of a tin panel subjected to in-plane combined (normal and shearing) loads is considered in ...
Gd2O3:Eu3+ phosphor particles processed through aerosol route
(Elsevier BV, 2005)
In this work, the influence of the Eu3+ luminescence center concentration on the structural, morphological and spectroscopic properties of powders obtained by an aerosol method was studied. In the method, gadolinium and ...
Structural and Luminescence Properties of Gd2O 3:Eu3+ and Y3Al5O12:Ce3+ Phosphor Particles Synthesized via Aerosol
(The Electrochemical Society, 2005)
Opportunities for the synthesis of ultrafine spherical particles with uniformly distributed components and phases are of special importance when materials for photonic application are considered. In this study, the nanophase, ...
Structural properties of europia-doped-gadolinia synthesized through aerosol
(Elsevier BV, 2007)
High purity europium-doped gadolinia (Gd2O3:Eu3+) have been prepared using spray pyrolysis technique yielding nanostructured non-agglomerated particles with spherical morphology. Comparative microstructural analysis was ...
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 ...
