Nonlinear properties and stability of SnO2 varistors prepared by evaporation and decomposition of suspensions
(Elsevier Sci Ltd, Oxford, 2005)
SnO2 varistors doped with CoO, Cr2O3 and Nb2O5 were prepared by evaporation and decomposition of suspensions. The composition of the varistors was optimized to improve electrical properties, such as nonlinearity, leakage ...
Synthesis and Biological Activities of Thio-avarol Derivatives
(Amer Chemical Soc, Washington, 2008)
Eleven new thio-avarol derivatives (3-13) were synthesized. Their antimicrobial, brine shrimp lethality, and free-radical scavenging activities and acetylcholinesterase inhibition, together with 12 already reported ...
Far infrared study of impurity local modes in palladium-doped PbTe and PbSnTe
(Elsevier Science Sa, Lausanne, 2009)
PbTe and Pb0.85Sn0.15Te single crystals. doped with Pd, were grown using the Bridgman method. Far infrared spectra were measured in the temperature range between 10 K and 300 K. The experimental spectra were numerically ...
Detection of hydrogen atom adduct of spin-trap DEPMPO. The relevance for studies of biological systems
(Amer Chemical Soc, Washington, 2005)
We proposed EPR spectroscopy using spin-trap DEPMPO as a novel method for the detection of a hydrogen atom (H-center dot) produced by chemical and biological systems. In complex EPR spectra of DEPMPO adducts in biological ...
Unique structural and transport properties of molybdenum chalcohalide nanowires
(Amer Physical Soc, College Pk, 2007)
We combine ab initio density functional and quantum transport calculations based on the nonequilibrium Green's function formalism to compare structural, electronic, and transport properties of Mo6S6-xIx nanowires with ...
Microstructural investigation of the PZT films prepared from the suspension of nanocrystalline powders
(Elsevier Sci Ltd, Oxford, 2004)
PZT thin films of composition Pb(Zr0.52Ti0.48)O-3 were prepared by a novel method from the suspension of nanocrystalline PZT powders. The powders were obtained by mechanochemical synthesis. Films were deposited on silicon ...
Strontium titanate films prepared by spray pyrolysis
(Elsevier Sci Ltd, Oxford, 2004)
Strontium titanate thin films were prepared by spray pyrolysis technique. Deposition parameters, such as solution concentration, time and temperature of deposition, and flow rate of carrier gas were optimized to obtain ...
Age-specific metal and accumulation patterns in different tissues of nase (Chodrostoma nasus) from the Medjuvrsje Reservoir
(Elsevier, Amsterdam, 2016)
Nase (Chodrostoma nasus L. 1758) specimens of four age classes (1(+) to 4(+)) were caught in July 2013 in the Medjuvrsje Reservoir. Concentrations of 14 metals and elements (Al, B, Ba, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Si, ...
Tailoring of morphology and orientation of LaNiO3 films from polymeric precursors
(Elsevier Sci Ltd, Oxford, 2007)
The aim of this work was to prepare lanthanum nickel oxide (LaNiO3, LNO) thin films of different morphology and orientation. The precursor solutions were prepared by a chemical method from citric salts of lanthanum and ...
Deposition of Pd nanoparticles on the walls of cathodically hydrogenated TiO2 nanotube arrays via galvanic displacement: A novel route to produce exceptionally active and durable composite electrocatalysts for cost-effective hydrogen evolution
(Elsevier Science Bv, Amsterdam, 2018)
Noble metal-based materials are inevitable components of cathodes for the hydrogen evolution reaction (HER) in future water electrolysis systems for clean hydrogen fuel production. However, designing active and durable ...
