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 ...
Grain growth during sintering of batio3 with lif
(Taylor & Francis Ltd, Abingdon, 1996)
The sintering behavior of BaTiO3 with LiF showed that it was possible to sinter barium titanate at temperatures below 1000 degrees C. Different combinations of the sintering powders were prepared by adding 1 to 5 w% LiF ...
Isopiestic Determination of the Osmotic and Activity Coefficients of the {yNaH(2)PO(4)+(1-y)KH2PO4}(aq) System at T=298.15K
(Springer/Plenum Publishers, New York, 2019)
Isopiestic measurements have been made for aqueous mixtures of NaH2PO4 and KH2PO4 at T=(298.15 +/- 0.01) K, at NaH2PO4 ionic strength fractions y=(0, 0.19108, 0.38306, 0.58192, and 1), assuming that both electrolytes ...
Boom-bust like dynamics of invasive black bullhead (Ameiurus melas) in Lake Sava (Serbia)
(Wiley, Hoboken, 2019)
The life-history traits and population dynamics of the black bullhead Ameiurus melas (Rafinesque) were studied monthly from August 2009 to December 2012 in Lake Sava in Belgrade (Serbia). This period included a mass mortality ...
Evaluation of genotoxic potential in the Velika Morava River Basin in vitro and in situ
(Elsevier Science Bv, Amsterdam, 2018)
The Velika Morava River is the greatest national Serbian river and the significant tributary of the Danube River. The major problems in the Velika Morava River Basin (VMRB) represent untreated industrial and municipal ...
Updated functional segregation of retinal ganglion cell projections in the tectum of a cyprinid fishfurther elaboration based on microelectrode recordings
(Springer, Dordrecht, 2019)
Single-unit responses of retinal ganglion cells (GCs) were recorded extracellularly from their axonal terminals in the tectum opticum (TO) of the intact fish (goldfish, carp). The depths of retinal units consecutively ...
Substituent Effects on the Patterns of Intermolecular Interactions of 3-Alkyl and 3-Cycloalkyl Derivatives of Phenytoin: A Crystallographic and Quantum-Chemical Study
(Amer Chemical Soc, Washington, 2019)
A series of five derivatives of the anticonvulsant drug phenytoin was synthesized, and their crystal structures were determined. The relationship between the molecular and crystal structure of the investigated compounds ...
Magneto-electric properties of xNi(0.7)Zn(0.3)Fe(2)O(4) - (1-x)BaTiO3 multiferroic composites
(Elsevier Sci Ltd, Oxford, 2018)
Di-phase ceramic composites, with general formula xNi(0.7)Zn(0.3)Fe(2)O(4) - (1-x)BaTiO3(x = 0.9, 0.7, 0.5, 0.3, 0.1), were prepared by a mixing method. X-ray analysis, for powder and ceramics, indicated the formation of ...
Electrostatically driven energy shift of molecular orbitals of benzene and nicotine in carbon nanotube gaps
(Springer, Dordrecht, 2021)
The requirement for controllable frontier orbital energy shift in single-molecule devices based on electronic (tunneling) transport yielded several rules for device design that lean on molecular level pinning to the ...
