Structural, morphological and optical study of nanostructured TiO2/Fe2O3 thick film
(Bor : Technical Faculty, 2013)
Thick films of nanostructured TiO2 (60 wt%) and alpha-Fe2O3 (40 wt%) were fabricated by screen printing technology on an alumina substrate. Samples were sintered in the temperature range 750-1350oC in air. Thick film paste ...
La-doped and La/Mn-co-doped Barium Titanate Ceramics
(Acta Physica Polonica A, 2013)
Barium titanate ceramics doped with 0.3 mol.% lanthanum and co-doped with 0.3 mol.% lanthanum and 0.05 mol.% manganese were investigated. The powders were prepared by a modified polymeric precursor method based on the ...
Different immobilization methods of soybean hull peroxidase on macroporous glycidyl methacrylate copolymers
(MTG - Topgraf Velika Gorica, 2013)
Wastewater treatment is a current and important environmental issue. Phenolic compounds most of which are
toxic and many even carcinogens, found in various polluted waters are non-biodegradable and present a serious
health ...
Mechanochemical synthesis of bismuth ferrite
(Univerzitet u Beogradu - Tehnički fakultet u Boru, Beograd, 2013)
A powder mixture of Bi2O3 and Fe2O3 was mechanically treated in a planetary ball mill in an air from 30 to 720 minutes. It was shown that the mechanochemical formation of BiFeO3 (BFO) phase was initiated after 60 min and ...
On strain-rate sensitivity and size effect of brittle solids: transition from cooperative phenomena to microcrack nucleation
(Springer Nature, 2013)
An idealized brittle microscale system is subjected to dynamic uniaxial tension in the medium-tohigh
strain-rate range (˙ε ∈ [100 s−1, 1×107 s−1]) to investigate its mechanical response under constrained
spatial and ...
Classification and fingerprinting of different berries based on biochemical profiling and antioxidant capacity
(Empresa Brasil Pesq Agropec, Brasilia Df, 2013)
The objective of this work was to evaluate the biochemical composition of six berry types belonging to Fragaria, Rubus, Vaccinium and Ribes genus. Fruit samples were collected in triplicate (50 fruit each) from 18 different ...
Spin-transfer torque at finite bias from density functional theory and non-equilibrium Green's functions
(American Physical Society, 2013)
The spin-transfer torque (STT) exerted on a magnetic layer by a spin-polarized current represents a powerful handle to manipulate the magnetization. This
can make magnetic random access memories a reality. We have now ...
Thermal and dissolved oxygen properties and fish assemblages of the Zlatar Reservoir
(The Serbian Water Pollution Control Society, 2013)
Silicon mediates iron acquisition by Strategy 1 plants
(Serbian Plant Physiology Society; Institute for Biologica l Research ,,Sinisa Stankovic", University of Belgrade, Bulevar despota Stefana 142, 11060 Belgrade, Serbia, 2013)
Silicon (Si) and iron (Fe) are respectively the second and the fourth most abundant minerals in the earth's crust. While the essentiality of Fe is discovered at the middle of the 19111 century, Si is still not fully accepted ...
Morphological and crystallographic characteristics of electrodeposited lead from a concentrated electrolyte
(Royal Soc Chemistry, Cambridge, 2013)
Electrodeposition of lead from a concentrated nitrate solution was examined by scanning electron microscopy (SEM) and by X-ray diffraction (XRD) analysis of the obtained powder particles. Single crystals of the (111) ...
