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 ...
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 ...
Specificity of the UPD of H to the structure of highly dispersed Pt on carbon support
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Home-made carbon cryogel synthesized by sol-gel polycondensation and freeze-drying is used as support for preparation of highly dispersed Pt catalyst that is made by a modified polyol synthesis method in an ethylene glycol ...
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 ...
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 ...
Effects of the air pollutant SO2 on leaves: Inhibition of sulfite oxidation in the apoplast by ascorbate and of apoplastic peroxidase by sulfite
(American Society of Plant Biologists, 1992)
After SO2 has entered leaves of spinach (Spinacia oleracea) through open stomata and been hydrated in the aqueous phase of cell walls, the sulfite formed can be oxidized to sulfate by an apoplastic peroxidase that is ...
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 ...
Pt/C doped by MoOx as the electrocatalyst for oxygen reduction and methanol oxidation
(Elsevier Science Bv, Amsterdam, 2008)
The oxidation of methanol and reduction of oxygen were studied on MoOx-Pt/C nano-catalysts prepared by the polyole method combined by MoOx post-deposition. The catalysts were characterized by TEM and EDX. The presented ...
Preparation and characterization TiOx-Pt/C catalyst for hydrogen oxidation reaction
(Royal Soc Chemistry, Cambridge, 2009)
The hydrogen oxidation reaction (HOR) was studied at the home made TiOx-Pt/C nanocatalysts in 0.5 mol dm(-3) HClO4 at 25 degrees C. Pt/C catalyst was first synthesized by modified ethylene glycol method (EG) on commercially ...
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 ...
