Non-isothermal crystallization kinetics of Y(2)Ti(2)O7
(Powder Technology, 2017)
The crystallization kinetics of Y2Ti2O7 powders prepared by a Pechini-type polymerized complex route was studied using differential thermal analysis under non-isothermal conditions. Apparent activation energies of ...
Particle size effects on the structure and emission of Eu3+: LaPO4 and EuPO4 phosphors
(Journal of Luminescence, 2018)
This paper provides the detailed study of (nano) particles size effect on structural and luminescent properties of LaPO4: Eu3+ synthesized by four different methods: high temperature solid-state, co-precipitation, reverse ...
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 ...
Evaluation of Staining-Dependent Colour Changes in Resin Composites Using Principal Component Analysis
(Scientific Reports, 2015)
Colour changes in Gradia Direct (TM) composite after immersion in tea, coffee, red wine, Coca-Cola, Colgate mouthwash, and distilled water were evaluated using principal component analysis (PCA) and the CIELAB colour ...
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 ...
Pm and Co2 Variability and Relationship in Different School Environments
(Chemical Industry and Chemical Engineering Quarterly / CICEQ, 2015)
Indoor air quality (IAQ) is very important for children health and well-being, since children are particularly vulnerable and sensitive to the presence of air pollutants. This study was performed in two naturally ventilated ...
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, ...
