Physico-chemical and mechanical properties and antibacterial activity of silver/poly(vinyl alcohol)/graphene nanocomposites obtained by electrochemical method
(Elsevier, 2016)
Silver/poly(vinyl alcohol) and silver/poly(vinyl alcohol)/graphene nanocomposites in different forms (colloid dispersion, thin films and hydrogel discs) were synthesized by electrochemical reduction of Ag+ ions at constant ...
Effects of Li+ co-doping on properties of Eu3+ activated TiO2 anatase nanoparticles
(Optical Materials, 2017)
Sol-gel technique for the synthesis of anatase TiO2 at 420 degrees C produces nanocrystals of 10-20 nm in size with Ti4+ in crystal volume and Ti3+ at terminal planes of the crystal. The study of Li+ co-doping effects on ...
Changes of Color and Fluorescence of Resin Composites Immersed in Beer
(Journal of Esthetic and Restorative Dentistry, 2016)
ObjectiveThe aim of this study was to evaluate changes of color and fluorescence of resin based composite exposed to beer. Materials and Methods84 samples (13 mm in diameter and 1.5 mm thick) of microhybrid composite Gradia ...
Indoor CO2 measurements in Serbian schools and ventilation rate calculation
(Energy, 2014)
The indoor air quality in schools is very important for health and learning abilities of children. The primary indoor CO2 source in classrooms is the respiration of school building occupants. Also, CO2 comes from outside ...
Numerical Simulation of Air Jet Attachment to ConvexWalls and Application to UAV
(Lecture Notes in Computational Science and Engineering, 2015)
In this paper, we present a numerical study of the wall jet flow over a convex surface, viz. the Coanda wall jet, and its application to a conceptual Unmanned Aerial Vehicle (UAV) design which uses the Coanda effect as a ...
On the improved finite volume procedure for simulation of turbulent flows over real complex terrains
(Journal of Computational Physics, 2015)
This article presents a new and substantially improved finite volume procedure for simulation of incompressible flows on non-orthogonal grids. Cell-centered least-squares gradients are obtained in a robust and highly ...
Modeling air concentration of fly ash in Belgrade, emitted from thermal power plants TNTA and TNTB
(Process Safety and Environmental Protection, 2017)
The aim of the study was to estimate if dust/fly ash emitted into the atmosphere from chimneys and the ash disposal sites of the thermal power plants Nikola Tesla A and B in Obrenovac could increase the concentration of ...
On the use of small and cheaper sensors and devices for indicative citizen-based monitoring of respirable particulate matter
(Elsevier, 2015)
Respirable particulate matter present in outdoor and indoor environments is a health hazard. The particle concentrations can quickly change, with steep gradients on short temporal and spatial scales, and their chemical ...
Experimental and Numerical Investigation of the Primary Fragmentation of a Lignite during Fluidized-Bed (FB) Devolatilization
(Energy and Fuels, 2015)
The paper presents a comparison between experimental and model results of primary fragmentation of a lignite coal in a fluidized bed (FB). In the experiments, the char particle size distribution and the general indicators ...
The boiler concept for combustion of large soya straw bales
(Energy, 2009)
In one of the largest agricultural companies in Serbia, with over 2000 ha of soya plantations, there are 4000 t/year of baled soya straw produced. Soya straw biomass is planned to be used as a renewable energy source for ...
