Chemical composition and biological activity of Gaultheria procumbens L. essential oil
(Elsevier, Amsterdam, 2013)
The aim of this study was to examine chemical composition and biological activity of Gaultheria procumbens L essential oil (EO) against food spoilage and oral microorganisms. The components of EO were identified by GC-MS. ...
Novel Pt catalyst on ruthenium doped TiO2 support for oxygen reduction reaction
(Elsevier, Amsterdam, 2013)
Ruthenium doped titanium oxide support was synthesized. The support was characterized by BET (Brunauer, Emmett, Teller) and X-ray diffraction techniques (XRD). Determined specific surface area was 41 m(2) g(-1). XRD revealed ...
Synthesis and characterization Pt nanocatalysts on tungsten based supports for oxygen reduction reaction
(Elsevier Science Bv, Amsterdam, 2012)
Platinum nanocatalysts on two tungsten based supports have been synthesized and characterized as catalysts for oxygen reduction reaction in 0.5 mol dm(-3) HClO4 solution, at 25 degrees C. Tungsten based support assigned ...
Stability, characterization and functionality of proton conducting NiO-BaCe0.85-xNbxY0.15O3-delta cermet anodes for IT-SOFC application
(Elsevier Science Sa, Lausanne, 2014)
There are many of properties of anodes based on proton conductors, like microstructure, conductivity and chemical stability, which should be optimized. In this work we were dealing with the influence of niobium on the ...
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 ...
PZT-nickel ferrite and PZT-cobalt ferrite comparative study: Structural, dielectric, ferroelectric and magnetic properties of composite ceramics
(Elsevier Sci Ltd, Oxford, 2018)
Comparative study of different PZT-based composite materials ((x)PbZr0.52Ti0.48O3 + (1-x)CoFe2O4 and (x) PbZr0.52Ti0.48O3 + (1-x)Ni0.7Zn0.3Fe2O4 (x = 0.8 and 0.9)) is presented in the frame of structural, dielectric, ...
Reducing sheet resistance of self-assembled transparent graphene films by defect patching and doping with UV/ozone treatment
(Elsevier, Amsterdam, 2018)
Liquid phase exfoliation followed by Langmuir-Blodgett self-assembly (LBSA) is a promising method for scalable production of thin graphene films for transparent conductor applications. However, monolayer assembly into thin ...
Fractality and Self-organization in the Orthodox Iconography
(Wiley-Hindawi, London, 2016)
The authors consider the Orthodox iconography of Byzantine style aimed at examining the existence of complex behavior and fractal patterns. It has been demonstrated that fractality in icons is manifested as two types-descending ...
Dielectric and relaxor behavior of BaBi4Ti4O15 ceramics
(Elsevier Science Sa, Lausanne, 2010)
Barium bismuth titanate BaBi4Ti4O15 (BBiT) ceramics have been prepared using non-conventional solid-state reaction route based on mechanochemical synthesis during intensive milling. The X-ray diffraction method was used ...
p-Type copper aluminum oxide thin films for gas-sensing applications
(Elsevier Science Sa, Lausanne, 2015)
In this study we deposited new, ternary thin films of copper aluminum oxide with p-type and n-type behavior using RF magnetron sputtering for use as chemical gas sensors. p-Type materials are known to be good catalysts and ...
