The Effect of Y2O3 Addition on Thermal Shock Behavior of Magnesium Aluminate Spinel
(Science of Sintering, 2009)
The effect of yttria additive on the thermal shock behavior of magnesium aluminate spinel has been investigated. As a starting material we used spinel (MgAl2O4)obtained by the modified glycine nitrate procedure (MGNP). ...
New non-orthogonality treatment for atmospheric boundary layer flow simulation above highly non-uniform terrains
(Thermal Science, 2016)
In this paper we validate an improved finite volume approximation of Reynolds averaged Navier-Stokes equations for simulation of wind flows in body-fitted grids generated by algebraic extrusion from digital terrain elevation ...
Structural Analysis of Guyed Mast Exposed to Wind Action
(Thermal Science, 2016)
The behavior of the mast is non-linear due to its slenderness and compliant guy-support system, having a tendency to lose stability and even crush suddenly. Wind load is one of the main factors affecting the stability of ...
Novel Fragmentation Model for Pulverized Coal Particles Gasification in Low Temperature Air Thermal Plasma
(Thermal Science, 2016)
New system for start-up and flame support based on coal gasification by low temperature air thermal plasma is planned to supplement current heavy oil system in Serbian thermal power plants in order to decrease air pollutions ...
Magnetic and Structural Studies of CoFe2O4 Nanoparticles Suspended in an Organic Liquid
(Journal of Nanomaterials, 2013)
We present a study of magnetic and structural properties of CoFe2O4 nanoparticles suspended in an organic liquid. Transmission electron microscopy shows that the nanoparticles have a narrow size distribution of average ...
Efficient As(V) removal by alpha-FeOOH and alpha-FeOOH/alpha-MnO2 embedded PEG-6-arm functionalized multiwall carbon nanotubes
(Chemical Engineering Research and Design, 2017)
A novel adsorbents, 6-arm amino polyethylene glycol functionalized multiwall carbon nanotubes (PEG/MWCNT) loaded with alpha-FeOOH (Fe/PEG/MWCNT), and hybrid alpha-FeOOH/alpha-MnO2 nano-deposit (Fe-Mn/PEG/MWCNT) were used ...
Electron paramagnetic resonance in Hg1-xMnxTe1-ySey
(Materials Science Forum, 2000)
Electron paramagnetic resonance has been studied in diluted magnetic semiconductor Hg1-xMnxTe1-ySey with y=0.01 and x=0.01, 0.03, 0.05, 0.14 and with y=0.075, x=0.14 in the temperature range 20-290 K. It is found that the ...
Impact of Co2 Concentration on Indoor Air Quality and Correlation with Relative Humidity and Indoor Air Temperature in School Buildings in Serbia
(Thermal Science, 2016)
Previous studies have shown that poorly ventilated classrooms can have negative impact on the health of children and school staff. In most cases, schools in Serbia are ventilated naturally. Considering their high occupancy, ...
Assessment Results of Fluid-Structure Interaction Numerical Simulation Using Fuzzy Logic
(Thermal Science, 2016)
A fuzzy approximation concept is applied in order to predict results of coupled computational structure mechanics and computational fluid dynamics while solving a problem of steady incompressible gas flow through thermally ...
Solid-phase extraction disk based on multiwalled carbon nanotubes for the enrichment of targeted pesticides from aqueous samples
(Journal of Separation Science, 2017)
A sensitive method for the determination of six varying polarity pesticides (imidacloprid, acetamiprid, carbendazim, simazine, linuron, and tebufenozide) based on a solid-phase extraction disk with multiwalled nanotubes ...
