Thermal diffusivity and electron transport properties of NTC samples obtained by the photoacoustic method
(Elsevier Science Sa, Lausanne, 2006)
Thermal diffusivity and electron transport parameters of sintered NTC samples were determined by the photoacoustic (PA) technique. Powder mixtures composed of MnO, NiO, CoO and Fe2O3 were milled to nanometer particle size. ...
Evaluation of kinetic data for crystallization of TiO2 prepared by hydrolysis method
(Springer, Dordrecht, 2000)
The formation of TiO2 prepared by hydrolysis method was presented. Thermodynamics and kinetics of anatase crystallization reaction were investigated. Differential method of kinetic data evaluation in non-isothermal conditions ...
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 ...
Study on bi-layered ceramics powders prepared by the mechanochemical synthesis
(Elsevier Science Sa, Lausanne, 2009)
Bi-layered structured ferroelectric materials-bismuth titanate, Bi4Ti3O12 (BIT) and barium-bismuth titanate, BaBi4Ti4O15 (BBT) powders were prepared by homogenization and sintering of mixture of stehiometric quantities of ...
Microstructural evolution and electric properties of mechanically activated BaTiO3 ceramics
(Elsevier Sci Ltd, Oxford, 2007)
Ceramic materials with a perovskite related structures such as non-doped and doped barium titanate ceramics are attracting much interest for their application as capacitor dielectrics, resistors, thermal sensors, etc. Since ...
Uptake of iron (Fe-59) complexed to water-extractable humic substances by sunflower leaves
(Taylor & Francis Inc, Philadelphia, 2003)
A research was carried out to evaluate the leaves' ability to utilize Fe supplied as a complex with water-extractable humic substances (WEHS) and the long-distance transport of Fe-59 applied to sections of fully expanded ...
Infrared reflectance of single-crystal jarandolite, CaB3O4(OH)3
(Twickenham : Mineralogical Soc., 2007)
Polarized far- and mid-infrared reflectance spectra were measured at room temperature for the new mineral species jarandolite, CaB3O4(OH)(3), for the two principal directions. Thirty three vibration modes for (E) over right ...
Phase evolution in Ce-doped yttrium-aluminum-based particles derived from aerosol
(Elsevier Sci Ltd, Oxford, 2007)
The common nitrates precursor solution leading to the Y3Al5O12:Ce3+ (YAG:Ce) composition with 2 at.% of cerium, is ultrasonically atomised and introduced into the tubular flow reactor at 320 degrees C. Having in mind that ...
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% ...
Monosaccharide-H2O2 reactions as a source of glycolate and their stimulation by hydroxyl radicals
(Elsevier Sci Ltd, Oxford, 2006)
An analysis of the H2O2-induced breakdown and transformation of different keto-monosaccharides at physiological concentrations reveals that glycolate and other short-chained carbohydrates and organic acids are produced. ...
