The surface structure of (110) faceted strontium titanate nanoparticles synthesized via solvothermal method has been resolved using high-resolution electron microscopy (HREM). We demonstrate that the surface is a titania-rich structure containing tetrahedrally coordinated TiO4 units similar to the family of (n × 1) reconstructions observed on (110) surfaces of bulk crystalline strontium titanat...

Strontium titanate (SrTiO 3) is one of the best studied substances showing a displacive phase transition [1]. At ambient temperature, it exhibits a cubic perovskite structure with the space group Pm3m. On cooling, a Brillouin zone-boundary softmode drives the second-order transition to an antiferrodis-tortive phase at T C = 105 K. The primary order parameter is the antiphase rotation of TiO 6-o...

INTRODUCTION The extent of wound contamination in gunshot injuries is still a topic of controversial debate. The purpose of the present study is to develop a model that illustrates the contamination of wounds with exogenous particles along the bullet path. MATERIAL AND METHODS To simulate bacteria, radio-opaque barium titanate (3-6 μm in diameter) was atomized in a dust chamber. Full metal ja...

In this work, the inductively coupled plasma etching technique was applied to etch the barium titanate thin film. A comparative study of etch characteristics of the barium titanate thin film has been investigated in fluorine-based (CF4/O2, C4F8/O2 and SF6/O2) plasmas. The etch rates were measured using focused ion beam in order to ensure the accuracy of measurement. The surface morphology of et...

Barium strontium titanate exhibits ferroelectric or paraelectric behavior that depends upon the composition and other factors, making it suitable for several applications. We have adopted conventional solid-state reaction route to synthesize magnesium-substituted barium with magnesium concentration (Mg = 0, 0.005, 0.010, 0.015). X-ray diffraction has confirmed perovskite cubic single phase. The...

The determination of barium and strontium directly from sea water by isotope dilution mass spectrometry proves to be an efficient, precise, and virtual blank free procedure. Results for an eastern Pacific profile confirm a regularly increasing barium concentration from 5 to 23 ,clg/kg at 2500 m, but strontium concentrations appear to be nearly homogeneous below 50 m at 7.6 f 0.1 I;lg/kg with a ...

We report the observation of intense extreme ultraviolet (EUV) emission from incandescently heated atomic hydrogen and atomized strontium. Typically the emission of extreme ultraviolet light from hydrogen gas is achieved via a discharge at high voltage, a high power inductively coupled plasma, or a plasma created and heated to extreme temperatures by RF coupling (e.g. > 10 6 K) with confinement...

Ferroelectric barium titanate nanoparticles (BTO NPs) may play critical roles in miniaturized passive electronic devices such as multi-layered ceramic capacitors. While increasing experimental and theoretical understandings on the structure of BTO doped have been developed over past decade, majority investigation was carried out thin-film materials; therefore, doping effect remains unclear. Esp...

Optical properties of sol-gel deposited Barium Strontium Titanate (BaxSr1-xTiO3, BST) thin films were studied to determine their suitability as light sensors. Crystallized BST formed by annealing in air at 700 °C for 1 h. Lattice parameters and grain sizes determined all the compositions. The band gap refractive index values samples from optical transmission spectra different Band compositions ...
