Active hip orthosis for assisting the training of the gait in Hemiplegics
(Kragujevac : University of Kragujevac, Faculty of Science, 2018)
The gait restoration is a significant component of the rehabilitation of patients with hemiplegia after central nervous system lesion. The typical symptom of the disability is the lack of hip extension during the stance ...
Sintering of mechanically activated Zno-TiO 2 powders
(Springer, 2008)
Zinc oxide and titanium dioxide powders mixed in an equimolar ratio are mechanically activated in a planetary ball mill and sintered under nonisothermal and isothermal conditions. Nonisothermal sintering is studied using ...
Mechanical properties and microstructure fractal analysis of refractory bauxite concrete
(Belgrade : International Institute for the Science of Sintering, 2015)
The surface topography analysis via fractals as a means of explanation of composite materials mechanical and microstructural characteristics has hardly been reported so far. This study proposes a method of fractal analysis ...
Choline chloride-based deep eutectic solvents in CaO-catalyzed ethanolysis of expired sunflower oil
(Elsevier, 2018)
Choline chloride (ChCl)-based deep eutectic solvents (DESs) with different amides or polyols as hydrogen bond donors were tested as cosolvents in the ethanolysis of expired sunflower oil catalyzed by either calcined or ...
The influence of alkaline cations on the mechanism and kinetics of dehydration of polymeric phthalatocuprate(II) dihydrates
(Elsevier, 2017)
Thermal dehydration of two heterometallic complexes containing dianion of phthalic acid, pht, Na2[Cu(pht)2] · 2H2O, 1, and K2[Cu(pht)2] · 2H2O, 2, was investigated under non-isothermal conditions. Mechanism and kinetics ...
Structure and Properties of Nanocrystalline Tetragonal BaTiO3 Prepared by Combustion Solid State Synthesis
(Belgrade : ETRAN, 2020)
Barium titanate (BaTiO3) attracts high scientific and technological attention due to good dielectric and electromechanical properties. Although BaTiO3 is one of the most frequently investigated ferroelectric materials, the ...
The influence of fluorine doping on the structural and electrical properties of the LiFePO4 powder
(Elsevier, 2017)
Low intrinsic electronic conductivity is the main disadvantage of LiFePO4 when used as a cathode material in lithium ion batteries. The paper offers experimental proofs of the theoretical prediction that fluorine doping ...
Structural and magnetic properties of nanocrystalline bismuth manganite obtained by mechanochemical synthesis
(Springer Netherlands, 2011)
We have studied the formation of BiMnO3 (BMO) nanocrystalline perovskite powder produced by high-energy milling of the constituent oxides. The crystal structure and the amount of crystalline and amorphous phases in the ...
Multiferroic Heterostructure BaTiO3/ε-Fe2O3 Composite Obtained by in situ Reaction
(Belgrade : International Institute for the Science of Sintering, 2021)
Solid-state reaction between BaTiO3 and Fe2O3 was used to produce a multiferroic heterostructure composite. Commercial BaTiO3 and Fe(NO3)3•9H2O were suspended in ethanol for 30 minutes in an ultrasound bath. The prepared ...
Far infrared study of impurity local modes in palladium-doped PbTe and PbSnTe
(Elsevier, 2009)
PbTe and Pb0.85Sn0.15Te single crystals, doped with Pd, were grown using the Bridgman method. Far infrared spectra were measured in the temperature range between 10 K and 300 K. The experimental spectra were numerically ...
