Representativity of Air Quality Control in Limited Number of Grid Points
(Journal of Environmental Protection and Ecology, 2014)
In this study, we point to loss of accuracy in representing a field of air pollution concentration due to reduction of number of monitoring points or changes in their location. Using a Gaussian-type diffusion model, a high ...
Determination of glass temperature of polymers by inverse gas chromatography
(Journal of Chromatography A, 2008)
Inverse gas chromatography (IGC) is an attractive technique for polymer characterization due to possible simultaneous determination of various physicochemical properties of polymer systems merely from retention times of ...
Some Results of a Radon Survey in 207 Serbian Schools
(Romanian Journal of Physics, 2013)
In this paper the results of radon concentration measurements performed in 207 schools in 7 communities of Southern Serbia are presented. The annual radon concentration varied from 17 Bqm(-3) to 428 Bqm(-3) with a median ...
Gallium-68 Labeled Iron Oxide Nanoparticles Coated with 2,3-Dicarboxypropane-1,1-diphosphonic Acid as a Potential PET/MR Imaging Agent: A Proof-of-Concept Study
(Contrast Media and Molecular Imaging, 2017)
The aim of this study was to develop a dual-modality PET/MR imaging probe by radiolabeling iron oxide magnetic nanoparticles (IONPs), surface functionalized with water soluble stabilizer 2,3-dicarboxypropane-1,1-diphosphonic ...
Non-isothermal crystallization kinetics of the heavy-group lanthanide dititanates
(Optical Materials, 2017)
The systematic investigation of crystallization kinetics of heavy-group lanthanide dititanate pyrochlores, HL2Ti2O7 (HL=Lu, Tm, Er, Ho, Y, Dy, and Tb) is presented. Materials are prepared by the Pechini-type polymerized ...
Electrochemical synthesis of nanosized hydroxyapatite/graphene composite powder
(Carbon Letters, 2015)
Electrochemical synthesis was employed to prepare a novel hydroxyapatite/graphene (HAP/Gr) composite powder suitable for medical applications as a hard tissue implant (scaffold). The synthesis was performed in a homogeneous ...
Characterization of cereal flours by fluorescence spectroscopy coupled with PARAFAC
(Food Chemistry, 2017)
This paper presents parallel factor analysis (PARAFAC) of fluorescence of cereal flours. Excitation emission matrices (EEMs) of different cereal flours (wheat, corn, rye, rice, oat, spelt, barley and buckwheat) were measured ...
Visible light absorption of surface modified TiO2 powders with bidentate benzene derivatives
(Microporous and Mesoporous Materials, 2015)
TiO2 powders with different specific surface area were prepared using reproducible, sol gel synthetic route and their ability to form hybrids with catechol and 5-amino salicylic acid was compared with the commercially ...
Analysis of Eu3+ Emission from Mg2TiO4 Nanoparticles by Judd-Ofelt Theory
(Advances in Condensed Matter Physics, 2015)
Eu3+ doped Mg-2 TiO4 (2 at% of Eu) nanoparticles which are 5 to 10 nm in diameter are prepared by Pechini-type polymerized complex route followed with the calcination in the temperature range from 400 degrees C to 700 ...
Charge-transfer complex formation between TiO2 nanoparticles and thiosalicylic acid: A comprehensive experimental and DFT study
(Optical Materials, 2017)
Under normal conditions, titanium dioxide does not absorb visible light photons due to large band gap. Nevertheless, when titanium dioxide nanoparticles (TiO2 NPs) are surface-modified with thiosalicylic acid (TSA), their ...
