INFLUENCE OF DOPING ION VALENCE AND SIZE ON PROPERTIES OF BiFeO3 MATERIALS
(Institute for Multidisciplinary Research, University of Belgrade Kneza Višeslava 1, 11000 Belgrade, Serbia, 2017)
Bismuth ferrite (BiFeO3) is one of the most promising single multiferroic materials, and for sure the most studied one. It expresses specific magnetic and electric properties well above the room temperature. However, the ...
Photodegradation of organic dye using BiFeO3 particles synthesized by ultrasound route
(Institut za multidisciplinarna istraživanja, Kneza Višeslava 1, 11000 Belgrade, Serbia, 2017)
BiFeO3 precursor powder was synthesized by ultrasound asissted sol–gel route
at relatively low temperature, starting from Bi-nitrate, Fe-nitrate, and ethylene
glycol. Structural, optical, and photocatalytic properties ...
Improved multiferroic properties of Nb doped BiFeO3
(Solid-State Science & Research Meeting, 2017)
Pure BiFeO3 (TN = 370 °C and TC = 826–845 °C) exhibits poor ferroelectric (high electrical conductivity) and weak ferromagnetism. In this study, up to 1% Nb5+ was introduced to replace Fe3+ (B-site doping) since it could ...
Investigation of structural and functional properties of doped BaTiO3 thin films for potential application in tunable microwave devices
(ECerS2017 July 9–13, 2017, Budapest, Hungary, 2017)
Ferroelectric behavior of perovskites makes these materials very popular for various applications
in microelectronics. Barium titanate is one of the most popular representatives
of perovskites and probably the most ...
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 ...
ENHANCED LOCAL PIEZOELECRTIC RESPONSE IN Mn- DOPED (K0.5Na0.5)0.99Sr0.01NbO3 FILMS
(Institute for Multidisciplinary Research, University of Belgrade, 2017)
The interest for the lead-free materials rapidly increased after 2003, when the
legislation against the use of lead-based piezoelectric materials in electronics had
passed. Among the numerous lead-free materials, special ...
Hemosporidije, krvni paraziti kod divljih ptica pevačica u Srbiji
(Sekcija za zoonoze SVD-a, Veterinarski specijalistički institut "Pančevo", 2017)
Diversity and prevalence of Haemosporidian blood microorganisms in wild birds are rather well studied across Western Europe from Sweden to Spain, while little has been known about the distribution and the ecology of avian ...
BiFeO3 THIN FILMS: INFLUENCE OF DOPING ON STRUCTURE AND PROPRETIES
(Faculty of Technology, University of Novi Sad Bul. cara Lazara 1, 21000 Novi Sad, Serbia, 2017)
Thin films of BiFeO3 and doped BiFeO3 were prepared by chemical solution deposition method. Because of low electrical resistivity of BiFeO3 which often prevents it to exhibit ferroelectric properties, several elements were ...
Improved properties of doped BaCe0.9Y0.1O3-δ as a proton conducting electrolyte for IT-SOFC
(Društvo za keramičke materijale Srbije, 2017)
The proton conductivity is an exclusive property of mixed oxides with
perovskite structure and large unit cell volume, such as BaCeO3 or SrCeO3. Doping
with aliovalent cations (Y3+) that replace Ce4+ induces formation ...
B-site doping as a strategy for tailoring BiFeO3 properties
(Društvo za keramičke materijale Srbije, 2017)
Ferroelectric, magnetic and structural properties of BiFe1–xNbxO3 (x = 0.002,
0.005 and 0.01) ceramics were investigated in order to study the influence of B-site
doping of multiferroic BiFeO3. It is known that pure ...
