Annealing and Doping Concentration Effects on Y2O3: Sm3+ Nanopowder Obtained by Self-Propagation Room Temperature Reaction
(Science of Sintering, 2013)
In this report, structure, morphology and luminescence of Y2O3:Sm3+ nanoparticles prepared by self-propagating room temperature reaction are presented. This new, simple and cost effective synthesis allows obtaining desired ...
Thermographic properties of Sm3+-doped GdVO4 phosphor
(Physica Scripta, 2012)
Rare-earth orthovanadates are important hosts for the luminescence of rare earth activators with considerable practical applications in the artificial production of light. In this paper we investigated the possibility for ...
Optical Properties of Y2O3:Eu3+ Red Emitting Phosphor Obtained via Spray Pyrolysis
(Acta Physica Polonica. Series A: General Physics, Physics of Condensed Matter, Optics and Quantum Electronics, Atomic and Molecular Physics, Applied Physics, 2009)
In the present work we explored the possibility of obtaining Y2O3:Eu3+ mu m-size particles by an ultrasonic spray pyrolysis method. As-prepared sample constitutes of spherical, hollow particles with an average size of 1 ...
Analysis and Prediction of Vibrations of Ball Bearings Contaminated By Open Pit Coal Mine Debris Particles
(Tehnicki Vjesnik = Technical Gazette, 2017)
Analysis of the relevant literature has shown that only few researches are dealing with the bearings dynamic behaviour in real environmental conditions where high concentration of solid contaminant particles is evident. ...
Corrosion Resistance of High Pressure Torsion Obtained Commercially Pure Titanium in Acidic Solution
(Tehnicki Vjesnik = Technical Gazette, 2017)
The enhancement of commercially pure titanium (cpTi) mechanical properties, which is required for its medical application, can be achieved by grain refinement obtained by severe plastic deformation. In addition to mechanical ...
Nonlinear dynamics of microtubules and series expansion unknown function method
(Chinese Journal of Physics, 2017)
Microtubules (MTs) are the most important part of cytoskeleton. In this paper we deal with two basic nonlinear differential equations coming from the two known models describing nonlinear dynamics of MTs. These equations ...
Clinicopathological characteristics and survival in Serbian patients with renal cell carcinoma: a retrospective analysis
(Journal of BUON, 2017)
Purpose: Indications of kidney cancer outcome in lower-income countries are based on an incidence/mortality ratio due to lack of survival information. This study was conducted to provide outcome data in Serbian patients ...
The Application of Experimental Design Methodology for the Investigation of Liquid Radioactive Waste Treatment
(Nuclear technology and radiation protection, 2017)
The sorption properties of waste facade, brick, and asphalt sample towards Sr(II), Co(II), and Ni(II) ions from single and multicomponent solutions were investigated. The highest sorption capacity was found for Ni(II) ions, ...
Graphene/MoS2 heterostructures as templates for growing two-dimensional metals: Predictions from ab initio calculations
(Physical Review Materials, 2017)
Preparation of single-atom-thick layers of ordinary metals has been a challenging task since their closely packed atoms lack layered structure with highly anisotropic bonding. Using computational modeling based on density ...
Synthesis and crystal structure of 1,2,3,4-tetrahydro-9-aminoacridine tetrachlorozincate(II) monohydrate
(Journal of the Serbian Chemical Society, 2010)
In the reaction of ZnCl(2) with tacrine hydrochloride in water novel tetracoordinated (C(13)H(15)N(2))(2)[ZnCl(4)]-H(2)O complex was obtained and characterized by elemental analysis, molar conductivity and X-ray analysis. ...
