Comparative study of CeO2 nanopowders obtained by the hydrothermal method from various precursors
(Elsevier Sci Ltd, Oxford, 2015)
The effects of common precursors used in the synthesis of CeO2 nanopowders were investigated, and the structural and spectral properties of the resulting products were compared. Two cerium (III) salts, i.e., Ce(NO3)(3)center ...
New Antitumour Natural Products from Marine Red Algae: Covering the Period from 2003 to 2012
(Bentham Science Publ Ltd, Sharjah, 2015)
This review covers the 2003-2012 literature data published for natural products originating from marine red algae. The focus is on new antitumour substances, together with details related to the organism sourced. It ...
Photocatalytic degradation of alprazolam in water suspension of brookite type TiO2 nanopowders prepared using hydrothermal route
(Elsevier Science Sa, Lausanne, 2015)
Two series of nanocrystalline brookite-type powders have been synthesized by using combined sal gel hydrothermal method with titanium tetrachloride (TiCI4) as a precursor and hydrothermal temperature and reaction time ...
In vitro anti-quorum sensing activity of phytol
(Taylor & Francis Ltd, Abingdon, 2015)
Anti-quorum sensing activity of the diterpene phytol was evaluated in vitro for the first time. This compound (at three sub-MIC concentrations - 0.5, 0.25 and 0.125 MIC, respectively) reduced the formation of Pseudomonas ...
Ultra-high breakdown field varistors prepared from individually synthesized nanoprecursors
(Elsevier Sci Ltd, Oxford, 2015)
Previously synthesized nanocrystalline ZnO doped with cobalt and manganese, Bi2O3 and Sb2O3 were the precursors for high voltage varistors preparation. Varistor ceramics were sintered at 750 degrees C, 770 degrees C or 900 ...
Low frequency noise characteristics of BaTiO3-NiFe2O4 composites at phase transition
(Institute of Electrical and Electronics Engineers Inc., 2015)
In this work we present detailed investigation of low frequency noise characteristics of BaTiO3-NiFe2O4 ceramic composites of different percentage of NiFe2O4. At the particular temperatures (that gets under the broad maximum ...
Kinetics of the oxygen evolution reaction on NiSn electrodes in alkaline solutions
(Elsevier Science Sa, Lausanne, 2015)
In order to examine the intrinsic catalytic activity and durability of the electrodeposited NiSn alloy electrodes and the electrodeposited Ni as a reference electrode material for the oxygen evolution reaction (OER) in ...
Ni-(Ebonex-supported Ir) composite coatings as electrocatalysts for alkaline water electrolysis. Part I: Hydrogen evolution
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
The hydrogen evolution reaction (HER) was studied at electrodeposited Ni and Ni-(Ebonex/Ir) composite coatings in 1 mol dm(-3) NaOH solution at 25 degrees C. The Ni-(Ebonex/Ir) coatings were electrodeposited from a nickel ...
Mechanochemically assisted solid-state and citric acid complex syntheses of Cu-doped sodium cobaltite ceramics
(Elsevier Science Sa, Lausanne, 2015)
In the last decade, the sodium cobaltite ceramic became a promising candidate for potential thermoelectric applications, because of its large thermopower and low resistivity. In this work, polycrystalline samples of ...
Ex-situ sensitization of ordered TiO2 nanotubes with CdS quantum dots
(Elsevier Sci Ltd, Oxford, 2015)
Ordered titania nanotubes (pore diameter approximate to 90 nm and wall thickness approximate to 10 nm) were obtained by the anodization technique and used for the ex-situ deposition of cadmium sulfide quantum dots (CdS ...
