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 ...
Roles of stolbur phytoplasma and Reptalus panzeri (Cixiinae, Auchenorrhyncha) in the epidemiology of Maize redness in Serbia
(Springer, Dordrecht, 2007)
Maize redness (MR), a disease causing midrib, leaf and stalk reddening and abnormal ear development in maize, has been reported from Serbia, Romania and Bulgaria for 50 years. Recent epiphytotics reduced yields by 40%-90% ...
Boron uptake by the root cortex symplast of tomato and pea plants: evidence for low-boron-induced active transport
(Csiro Publishing, Clayton, 2007)
The objective of this research was to test the hypothesis of the existence of an active boron ( B) uptake into the cortical cells induced by low B supply. The uptake of B was characterised in two tomato ( Lycopersicon ...
Screen printed PLZT thick films prepared from nanopowders
(Elsevier Sci Ltd, Oxford, 2007)
The gap between the bulk materials and thin films can be filled with thick films suitably designed and appropriate processed. Thick films of complex system like lead-lanthanum-zirconium titanate (PLZT) is difficult to ...
Spectroscopic study of spinel ZnCr2O4 obtained from mechanically activated ZnO-Cr2O3 mixtures
(Elsevier Sci Ltd, Oxford, 2007)
A mixture of starting ZnO and Cr2O3 powders in equimolar quantities was mechanically activated by grinding using a high energy vibro-mil I for 0, 40 and 80 min. The spinet ZnCr2O4 was prepared from activated mixtures by a ...
Short-term interactions between nitrate and iron nutrition in cucumber
(Csiro Publishing, Collingwood, 2007)
Cucumber (Cucumis sativus L.) plants were precultured for 7 days in either optimal (10 mu M) or low (0.5 mu M) Fe conditions and then grown for further 5 days in a N-free nutrient solution with (+Fe) or without (-Fe) 10 ...
Effect of ageing on optical and thermal properties of YBa2Cu3O7-delta
(Carl Hanser Verlag, Munich, 2007)
Photoacoustic phase and amplitude spectra of YBa2Cu3O7-delta samples synthesised 18 years ago were measured and numerically analysed. The value of thermal diffusivity obtained on the aged samples was lower than the values ...
