Effect of annealing atmosphere on phase formation and electrical characteristics of bismuth ferrite thin films
(Pergamon-Elsevier B.V. Ltd, 2009-08-05)
Bismuth ferrite thin films were deposited on Pt/Ti/SiO(2)/Si substrates by a soft chemical method and spin-coating technique. The effect of annealing atmosphere (air, N(2) and O(2)) on the structure and electrical properties ...
Biomimetic apatite formation on Ultra-High Molecular Weight Polyethylene (UHMWPE) using modified biomimetic solution
(Springer, 2009-06-01)
Modifications were performed on a biomimetic solution (SBF), according to previous knowledge on the behavior of ions present in its composition, in order to obtain apatite coatings onto Ultra-High Molecular Weight Polyethylene ...
Efficient microwave-assisted hydrothermal synthesis of CuO sea urchin-like architectures via a mesoscale self-assembly
(Royal Soc Chemistry, 2010-01-01)
For the first time, we provide evidence for both heterogeneous nucleation at the mesoscopic scale and the progression of the non-classical crystallization process during the microwave synthesis of cupric oxide (CuO) with ...
Electrochemical Behavior of a Glassy Carbon Electrode Chemically Modified with Nickel Pentacyanonitrosylferrate in Presence of Sulfur Compounds
(Wiley-Blackwell, 2011-06-01)
The glassy carbon electrode was modified with a nickel pentacyanonitrosylferrate film by electrodeposition of Ni and subsequent derivatization with NaPCNF. The film was characterized by XPS and electrochemical methods. ...
Size effects of polycrystalline lanthanum modified Bi4Ti3O12 thin films
(Pergamon-Elsevier B.V. Ltd, 2008-01-08)
The film thickness dependence on the ferroelectric properties of lanthanum modified bismuth titanate Bi3.25La0.75Ti3O12 was investigated. Films with thicknesses ranging from 230 to 404 nut were grown on platinum-coated ...
An efficient microwave-assisted hydrothermal synthesis of BaZrO3 microcrystals: growth mechanism and photoluminescence emissions
(Royal Soc Chemistry, 2010-01-01)
The effect of different synthetic conditions (both template and chloride precursor concentration) on the morphologies of BaZrO3 microcrystals was systematically investigated. Three different templates, polyethylene glycol ...
Surface Passivation of Nanoporous TiO2 via Atomic Layer Deposition of ZrO2 for Solid-State Dye-Sensitized Solar Cell Applications
(Amer Chemical Soc, 2009-10-22)
We report here the utilization of atomid layer deposition to passivate surface map states in mosoporous TiO2 nanoparticles for solid state dye sensitized solar cells based on 9,9'-spirobifluorene (spiro-OMeTAD). By depositing ...
Relevance of Electronic Effects on the Yield of CO2 from Methanol Oxidation
(Amer Chemical Soc, 2012-01-17)
The yields of products of methanol oxidation (HCHO, HCOOH, and CO2) were studied for carbon-supported PtRu nanoparticles having different amounts of alloyed and oxide phases. It is demonstrated that the increase in the Pt ...
Platinum-coated nanostructured oxides for active catalytic electrodes
(Elsevier B.V., 2011-10-25)
In this work we propose the use of platinum-coated nanostructured oxides for improving the redox rate of active electrodes for applications in catalysts for water splitting, fuel cells, organic depollution, etc. In order ...
Up-conversion properties of lanthanide-organic frameworks and how to track ammunitions using these materials
(Royal Soc Chemistry, 2012-01-01)
This manuscript reports the first example of up-conversion properties involving Yb3+ and Tb3+ ions in five isostructural Lanthanide-Organic Frameworks (LnOFs), herein designated as UCMarker-1 to UCMarker-5, respectively, ...
