Event-by-event mean p(T) fluctuations in pp and Pb-Pb collisions at the LHC
(European Physical Journal C. Particles and Fields, 2014)
Event-by-event fluctuations of the mean transverse momentum of charged particles produced in pp collisions at root s = 0.9, 2.76 and 7 TeV, and Pb-Pb collisions at root S-NN = 2.76 TeV are studied as a function of the ...
NMR relaxometric properties and cytotoxicity of Gd2O3 nanoparticle suspensions in an organic liquid
(Journal of Nanoparticle Research, 2014)
Gd2O3 nanoparticles and their agglomerates from approximately 10 to 80 nm in size suspended in an organic liquid were synthesized via polyol route. The reaction between diethylene glycol and added acetic acid, which occurred ...
Composite profile of the Fe K alpha spectral line emitted from a binary system of supermassive black holes
(Advances in Space Research, 2014)
We used a model of a relativistic accretion disk around a supermassive black hole (SMBH), based on ray-tracing method in the Kerr metric, to study the variations of the composite Fe K alpha line emitted from two accretion ...
RR interval-respiratory signal waveform modeling in human slow paced and spontaneous breathing
(Respiratory Physiology and Neurobiology, 2014)
Our aim was to model the dependence of respiratory sinus arrhythmia (RSA) on the respiratory waveform and to elucidate underlying mechanisms of cardiorespiratory coupling. In 30 subjects, RR interval and respiratory signal ...
Physicochemical investigation of some archaeometallurgical findings from locality Kmpije (Bor, Serbia)
(Journal of Thermal Analysis and Calorimetry, 2014)
Preliminary results of physicochemical investigation of some archaeometallurgical findings from Kmpije locality in vicinity of Bor (Serbia) are presented in this paper. Ancient samples of prehistoric origin were investigated ...
Elongated titania nanostructures as efficient photocatalysts for degradation of selected herbicides
(Applied Catalysis. B: Environmental, 2014)
Titanium dioxide nanotubes (TNT) were synthesized via hydrothermal method and calcined at various temperatures. The obtained calcined TiO2 nanomaterials with specific elongation orientation were characterized by transmission ...
Synthesis of ultra-thin oxide layer in laser-treated 3x (Al/Fe)/Si multilayer structure
(Journal of Materials Science, 2014)
The conditions of ultra-thin oxide films synthesized as the Al/Fe multilayer structures after the surface treatment with femtosecond laser radiation were studied. Thin films composed of three (Al/Fe) bilayers were deposited ...
Chemical speciation of metals in unpolluted soils of different types: Correlation with soil characteristics and an ANN modelling approach
(Elsevier, 2016)
The distribution of elements in soil fractions affects their mobility and availability and thus their potential beneficial or harmful impact on ecosystems, biota and humans. Different mineralogical and chemical characteristics ...
Sol-Gel Derived Eu3+-Doped Gd2Ti2O7 Pyrochlore Nanopowders
(Journal of Nanomaterials, 2015)
Herein we presented hydrolytic sol-gel synthesis and photoluminescent properties of Eu3+-doped Gd2Ti2O7 pyrochlore nanopowders. According to Gd2Ti2O7 precursor gel thermal analysis a temperature of 840 degrees C is identified ...
A novel reduction-oxidation synthetic route for hafnia
(Elsevier, 2016)
Amorphous hafnia (HfO2) powders were synthesized through a novel reduction oxidation route, in which, metal hafnium was reduced from hafnium tetrachloride (HfCl4) by sodium borohydride (NaBH4), and then oxidized in ambient ...
