Effect of traffic on the soil contamination with polycyclic aromatic hydrocarbons (PAHs)
(Taylor & Francis Ltd, Abingdon, 2008)
The level of the environment pollution with polycyclic aromatic hydrocarbons is mainly in correlation with degree of the region industrialization and the traffic density. The aim of this study was to determine the effect ...
New strain of 'Candidatus Phytoplasma ulmi' infecting Ulmus minor and U. laevis in Serbia
(Wiley, Hoboken, 2008)
Elm yellows (EY) phytoplasma (‘Candidatus Phytoplasma ulmi’) is the causal agent of a decline in American elms in North America, and in Eurasian elm species and hybrids in Europe (Lee et al., 2004). EY is known to infect ...
The effect of hydrogen co-deposition on the morphology of copper electrodeposits. II. Correlation between the properties of electrolytic solutions and the quantity of evolved hydrogen
(Elsevier Science Sa, Lausanne, 2008)
Formation of irregular deposits by electrodeposition from acid sulfate solutions of various H2SO4 concentrations was examined by the determination of the average current efficiency of hydrogen evolution and by the scanning ...
The ionic equilibrium in the CuSO4-H2SO4-H2O system and the formation of the honeycomb-like structure during copper electrodeposition
(Srpsko hemijsko društvo, Beograd, 2008)
The ionic equilibrium of the species in the CuSO4-H2SO4-H2O system was employed to systematize the conditions of copper electrodeposition leading to the formation of the honeycomb-like structure. The reason why CuSO4 ...
History and challenges of barium titanate: Part I
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2008)
Barium titanate is the first ferroelectric ceramics and a good candidate for a variety of applications due to its excellent dielectric, ferroelectric and piezoelectric properties. Barium titanate is a member of a large ...
A detailed XRD and FTIR analysis of Bi2O3 doped ZnO-SnO2 ceramics
(A Global Road Map for Ceramic Materials and Technologies: Forecasting the Future of Ceramics, Intern, 2008)
ZnO-SnO2 ceramics were prepared with a traditional powder mixed oxide route by mixing starting powders of ZnO and SnO2 in the molar ratio 2:1 and adding small amounts (0.5; 1.0; and 1.5 molar%) of Bi 2O3. These mixtures ...
Microstructural characterization of mechanicallyactivated ZnO powders
(Wiley, Hoboken, 2008)
In this paper, changes of microstructural characteristics of disperse systems during mechanical activation of zinc oxide (ZnO) have been investigated. ZnO powder was activated by grinding in a planetary ball mill in a ...
Structural characterization of mechanically milled ZnO: influence of zirconia milling media
(IOP Publishing Ltd, Bristol, 2008)
Zinc oxide nanoparticles were obtained by milling in a planetary ball mill with a zirconia milling assembly for up to 5 h in air. The samples were characterized by scanning electron microscopy, x-ray diffraction (XRD) and ...
Far infrared spectroscopy of Pb0.85Sn0.15Te alloy doped with Ni
(Carl Hanser Verlag, Munich, 2008)
Far infrared reflectivity spectra of single crystal Pb0.85Sn0.15Te doped with Ni were measured in the temperature range between 10 K and 300 K. Analysis of the experimental spectra was made using a fitting procedure based ...
