History and Challenges of Barium Titanate: Part II
(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 ...
Anticancer Properties of Ganoderma Lucidum Methanol Extracts In Vitro and In Vivo
(Routledge Journals, Taylor & Francis Ltd, Abingdon, 2009)
Anticancer activities of various extracts of the medicinal mushroom, Ganoderma lucidum, have been widely demonstrated and are mainly associated with the presence of different bioactive polysaccharides and triterpenoids. ...
Occurrence and Distribution of Grapevine Yellows Caused by Stolbur Phytoplasma in Montenegro
(Wiley, Hoboken, 2009)
In August 2008, grapevine yellows (GY)-like symptoms were observed in vineyards near Podgorica, Montenegro. A survey of the grape growing area of Montenegro was conducted to identify and determine the distribution of ...
Intrinsic resistivity of sintered nickel manganite vs. powder activation time and density
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2008)
In this work the DC resistivity of sintered nickel manganite NiMn2O4 (NTC thermistor material) was studied as a function of additional powder activation time in a planetary ball mill (0, 5, 15, 30, 45 and 60 min). The ...
Electrical and transport properties of nickel manganite obtained by Hall effect measurements
(Springer, Dordrecht, 2009)
Intrinsic resistivity and carrier transport parameters of sintered nickel manganite samples (NTC thermistor grade) were determined using a Hall effect measurement system based on the van der Pauw method. Powder mixtures ...
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 ...
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 ...
Synthesis of BaTiO3 from a mechanically activated BaCO3-TiO2 system
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2008)
In this article the solid state reaction of BaTiO3 formation from a mechanically activated BaCO3-TiO2 system has been investigated. An equimolar mixture of BaCO3 and TiO2 powders was activated in a planetary ball mill in ...
Temperature dependence of fractal dimension of grain boundary region in SnO2 based ceramics
(Springer, New York, 2006)
Fractal dimensions of grain boundary region in doped SnO2 ceramics were determined based on previously derived fractal model. This model considers fractal dimension as a measure of homogeneity of distribution of charge ...
Study of Barium Bismuth Titanate Prepared by Mechanochemical Synthesis
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2009)
Barium-bismuth titanate, BaBi4Ti4O15 (BBT), a member of Aurivillius bismuth-based layer-structure perovskites, was prepared from stoichiometric amounts of barium titanate and bismuth titanate obtained via mechanochemical ...
