Electrical and thermal properties of poly(methylmetacrylate) composites filled with electrolytic copper powder
(Elsevier, 2017)
The results of experimental studies of the properties of composite materials based on poly(methylmetacrylate) (PMMA) matrices filled with electrolytic copper powder, having very high dendritic structure, are presented in ...
Enhancement of thermoelectric properties induced by Cu substitution in NaCo2O4
(4th Conference of the Serbian Society for Ceramic Materials, 2017)
In this work polycrystalline samples of NaCo2–xCuxO4 (x = 0, 0.01, 0.03, 0.05)
were obtained from the powder precursors synthesized in two different ways: 1) by a
mechanochemically assisted solid-state reaction method ...
The effect of gadolinium substitution on the structural, ferroelectric and magnetic properties of bismuth ferrite ceramics
(Institut za multidisciplinarna istraživanja, Kneza Višeslava 1, 11000 Belgrade, Serbia, 2017)
Bi1-xGdxFeO3 (x = 0.01; 0.05; 0.075; 0.09; 0.10; 0.20; 0.30) powders were synthesized by hydro-evaporation method. The optimization of sintering conditions indicated that temperature of 870 °C and time of 6 hours (after ...
Subclinical hypothyroidism in gravide albino oxford rats cause delayed osteogenic differentiation in newborns
(Faculty of Veterinary Medicine, University of Zagreb, Croatia, 2017)
The effects of maternal hypothyroidism on the development and function of different
organs of their offspring are well known. It is unclear how its subclinical form affects some
of these processes, including endochondral ...
TEM study of basal-plane inversion boundaries in Sn‐Doped ZnO
(Ruđer Bošković Institute and Croatian Microscopy Society, Rovinj (Croatia), 2017)
Various dopants are known to produce inversion boundaries (IBs) in ZnO, causing polarity inversion across the interface. These are found either in basal or pyramidal planes and can be of head-to-head or tail-to-tail ...
Creating aperiodic photonic structures by synthesized Mathieu-Gauss beams
(Physical Review A, 2017)
We demonstrate a kind of aperiodic photonic structure realized using the interference of multiple Mathieu-Gauss beams. Depending on the beam configurations, their mutual distances, angles of rotation, or phase relations ...
Strontium-doping effects in solution derived lead-free ferroelectric K(0.5)Na(0.5)NbO3 thin films
(E-MRS 2017 Spring Meeting & Exhibit, May 22 to 26, 2017, Strasbourg, France, 2017)
Potassium sodium niobate, K0.5Na0.5NbO3 (KNN) is an environment-friendly lead-free alternative to highly efficient lead-based piezoelectrics. The poor functional properties of the KNN thin films prepared by chemical solution ...
Synthesis and photocatalytic activity of N-doped TiO2/composites
(University of Belgrade, Institute for Multidisciplinary Research, 2017)
N-doped TiO2/carbon composites (N-TiO2/HTC) were synthesized by
hydrothermal carbonization using glucose, titanium isopropoxide and melamine, as
a carbon, titanium and nitrogen precursors, respectively. In order to achieve ...
Imaging and regional distribution of copper, zinc, manganese and iron in sclerotic hippocampi of patients with mesial temporal lobe epilepsy
(Biohemijsko društvo Srbije, 2017)
Mesial temporal lobe epilepsy (mTLE) represents the most common subtype of human
focal epilepsies and perhaps the best-characterized disorder of this type 1
. Hippocampal
sclerosis (HS) is the most common histopathologic ...
