Effects of mechanical and thermal activation on pozzolanic activity of kaolin containing mica
(Elsevier, 2016)
Kaolin from a Serbian deposit, characterized by high content of impurities, such as mica and quartz, disordered kaolinite and high specific surface area, was subjected to thermal and mechanical activation on a large scale. ...
Thermal stability and degradation of binuclear hexaaqua-bis(ethylenediamine)-(μ 2-pyromellitato)dinickel(II) tetrahydrate
(Springer, 2016)
Thermal degradation of ternary transition metal complex containing tetraanion of pyromellitic acid, pyr, and ethylenediamine, en, [Ni2(en)2(H2O)6(pyr)]·4H2O, 1, was investigated under non-isothermal conditions. The mechanism ...
Electronic structure and X-ray spectroscopic properties of YbNi2P2
(Elsevier, 2016)
X-ray absorption spectrum at the Yb L3 edge and X-ray emission spectra of Ni and P at the K and L2,3 edges have been studied experimentally and theoretically in the mixed valent compound YbNi2P2 with ThCr2Si2 type crystal ...
Stimulation map for control of functional grasp based on multi-channel EMG recordings
(Elsevier, 2016)
Transcutaneous activation of muscles with electrical stimulation has limited selectivity in recruiting paralyzed muscles in stroke patients. However, the selectivity could be increased by the application of smaller electrodes ...
Serbia Robotics Hall of Fame: the Impact of the Past
(Academic Mind, 2016)
The paper presents a list of the most influential works of Serbian robotics. The list has been synthesized using document citation data from the Elsevier Scopus database and it shows that the impact of Serbia, compared to ...
Assessment of CaTiO3, CaMnO3, CaZrO3 and Ca2Fe2O5 perovskites as heterogeneous base catalysts for biodiesel synthesis
(Elsevier, 2016)
Calcium-containing perovskites CaTiO3, CaMnO3, CaZrO3 and Ca2Fe2O5 were synthesized by calcination of mechanochemically treated stoichiometric mixtures of CaCO3 and either TiO2, MnO2, ZrO2 or Fe2O3 powders. X-ray diffraction ...
Synthesis and characterization of Pd nanocatalyst at tungsten carbide based support for fuel cells application
(Belgrade : Materials Research Society of Serbia, 2016)
Tungsten carbide was prepared by polycondensation of resorcinol and formaldehyde in the presence cetyltrimethylammonium bromide (CTABr) surfactant. Pd nanocatalyst at this support was synthesized by borohydride reduction ...
Influence of starting powder milling on structural properties, complex impedance, electrical conductivity and permeability of Mn–Zn ferrite
(Springer, 2016)
In this work we have analyzed how milling starting commercial Mn–Zn powder prior to the sintering process has an influence on electrical conductivity, relative permittivity and complex impedance in the frequency range from ...
New insights into BaTi1–xSnxO3 (0 ≤ x ≤ 0.20) phase diagram from neutron diffraction data
(International Union of Crystallography, 2016)
Neutron powder diffraction (NPD) was employed to further investigate the BaTi1−xSnxO3 (BTS) system previously studied by X-ray diffraction. The room-temperature phase compositions and crystal structures of BTS samples with ...
Optical and morpho-structural properties of ZnO nanostructured particles synthesized at low temperature via air-assisted USP method
(Springer Berlin Heidelberg, 2016)
Here, we report on the ZnO nanoparticles processing employing low-temperature (500 °C) ultrasonic spray pyrolysis (USP) method, using different Zn nitrate precursor solution concentrations (0.01, 0.1 and 1.0 M). Particle ...
