Specificity of the UPD of H to the structure of highly dispersed Pt on carbon support
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Home-made carbon cryogel synthesized by sol-gel polycondensation and freeze-drying is used as support for preparation of highly dispersed Pt catalyst that is made by a modified polyol synthesis method in an ethylene glycol ...
Polymorphism in liquid crystals from star-shaped mesogens
(Taylor & Francis Ltd, Abingdon, 2007)
Star-shaped molecules, based on a phloroglucinol core with three oligobenzoate arms, are powerful mesogens that can be combined to columnar liquid crystalline materials and soft organic crystals. The structural properties ...
Oxygen reduction at platinum nanoparticles supported on carbon cryogel in alkaline solution
(Srpsko hemijsko društvo, Beograd, 2007)
The oxygen reduction reaction was investigated in 0.1 M NaOH solution, on a porous coated electrode formed of Pt particles supported on carbon cryogel. The Pt/C catalyst was characterized by the X-ray diffraction (XRD), ...
Experimental evaluation of insecticides for Colorado potato beetle (Leptinotarsa decemlineata say) control in Serbia
(Int Soc Horticultural Science, Leuven 1, 2007)
Biological efficacy of the most frequently used and some newly-introduced insecticides for controlling Colorado potato beetle (Leptinotarsa decemlineata Say) in Serbia was evaluated in Indjija (in 2000 and 2003), Zemun ...
Studies of the efficacy of insecticides against pepper-infesting aphids (Aphididae)
(Int Soc Horticultural Science, Leuven 1, 2007)
Green peach aphid (Myzus persicae Sultzer) is permanently exposed to selection pressure by insecticidal treatments. This has resulted in the aphid populations to develop resistance to insecticides most applied in a number ...
Microstructural properties of PZT thin films deposited on LaNiO3-coated substrates
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
The modified polymeric precursor method (Pechini method) was successfully used for the preparation of epitaxial and polycrystalline ferroelectric Pb(Zr0.52Ti0.48)O-3 (PZT) thin films. Films were deposited on LaNiO3 (LNO) ...
Synthesis of pure and doped LaMnO3 powders from citrate precursors
(Trans Tech Publications Ltd, 2007)
In this work pure and doped LMO were prepared using modified Pechini method from lanthanum and manganese citrates. Lanthanum citrate was prepared starting from La2O3, while manganese citrate was prepared from Mn(NO3)(2). ...
Experimental evaluation of insecticide efficacy in controlling Brevicoryne brassicae L. in cabbage
(Int Soc Horticultural Science, Leuven 1, 2007)
Cabbage aphid (Brevicoryne brassicae L.) is an important and highly destructive insect pest of cabbage in Serbia. It is capable of inflicting serious crop losses on cabbage and other brassica crops in some seasons, especially ...
A method for detecting the effect of magnetic field on activity changes of neuronal populations of Morimus funereus (Coleoptera, Cerambycidae)
(Wiley-Liss, Hoboken, 2007)
Modification of a new method for detecting changes in the activities of neuronal population and the nearest neuron is described. Preliminary measurements of the influence of a static magnetic field (2 mT) on neuronal ...
Investigation of zinc stannate synthesis using photoacoustic spectroscopy
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2007)
Mixtures of ZnO and SnO2 powders, with molar ratio of 2:1, were mechanically activated for 40, 80 and 160 minutes in a planetary ball mill. The resulting powders were compacted into pellets and non-isothermally sintered ...
