Preparation of ultrathin PZT films by a chemical solution deposition method from a polymeric citrate precursor
(Elsevier Sci Ltd, Oxford, 2010)
Ultrathin PZT film was prepared using a chemical solution deposition method from polymeric citrate precursors. The PZT solution was spin-coated on an amorphous silica layer formed on a Si(l 0 0) substrate. The films were ...
Electrical properties of lanthanum doped barium titanate ceramics
(Elsevier Science Inc, New York, 2011)
Pure and lanthanum doped barium titanate (BT) ceramics were prepared by sintering pellets at 1300 degrees C for 8 h, obtained from nanopowders synthesized by the polymeric precursor method. XRD results showed formation of ...
Structural, ferroelectric and magnetic properties of BiFeO3 synthesized by sonochemically assisted hydrothermal and hydro-evaporation chemical methods
(Elsevier Sci Ltd, Oxford, 2016)
BiFeO3 powders were synthesized by sonochemically assisted hydrothermal and hydro-evaporation methods. The X-ray diffraction confirmed the presence of secondary phases, Bi25FeO39 and Bi2Fe4O9, in as prepared BiFeO3 powders. ...
Core-shell carbon fiber"Co1.5Mn1.5O4 mesoporous spinel electrode for high performance symmetrical supercapacitors
(Elsevier, Amsterdam, 2020)
We report a mesoporous composite system consisting of carbon fiber cores surrounded with Co1.5Mn1.5O4 spinel nanocrystal shells, synthesized by a simple two-step process involving single-nozzle co-electrospinning and ...
Microstructural evolution and electric properties of mechanically activated BaTiO3 ceramics
(Elsevier Sci Ltd, Oxford, 2007)
Ceramic materials with a perovskite related structures such as non-doped and doped barium titanate ceramics are attracting much interest for their application as capacitor dielectrics, resistors, thermal sensors, etc. Since ...
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 ...
Significance of silicon uptake, transport, and deposition in plants
(Oxford Univ Press, Oxford, 2020)
Numerous studies have shown the beneficial effects of silicon (Si) for plant growth, particularly under stress conditions, and hence a detailed understanding of the mechanisms of its uptake, subsequent transport, and ...
High-performance hydrogen evolution electrocatalysis using proton-intercalated TiO2 nanotube arrays as interactive supports for Ir nanoparticles
(Royal Soc Chemistry, Cambridge, 2020)
Developing ultraefficient electrocatalytic materials for the hydrogen evolution reaction (HER) with low content of expensive platinum group metals (PGMs) via low-energy-input procedures is the key to the successful ...
Electrochemical oxidation of ethanol on palladium-nickel nanocatalyst in alkaline media
(Elsevier, Amsterdam, 2016)
Pd-Ni/C catalyst was synthesized employing a borohydride reduction method. The high area Ni was first dispersed on the carbon support and then modified by Pd nanoparticles. Transmission electron microscopy confirmed ...
Germanium-68 as an Adequate Tracer for Silicon Transport in Plants. Characterization of Silicon Uptake in Different Crop Species
(Amer Soc Plant Biologists, Rockville, 2007)
A basic problem in silicon (Si) uptake studies in biology is the lack of an appropriate radioactive isotope. Radioactive germanium-68 (Ge-68) has been used previously as a Si tracer in biological materials, but its suitability ...
