Some well-known Pb-based ferroelectric materials include PbTiO3 (PTO) and PbZrTiO3 (PZT) [1-2].
Based on a report in Nature, Ahart et al. [6] recommended designing other possible materials in PbTiO3 compound.
However, these results are acceptable in predicting new materials such as SnTO and GTO.

It is relevant for a variety of materials problems such as particle dispersion in castings, reinforcement of metal matrix composites etc.
The ESA Solidification and Quench Furnace (SQF) installed in the Materials Science Lab (MSL) on the International Space Station (ISS) is a Bridgeman-type furnace that can operate to a maximum temperature of 1050 °C.
Material composition measurement.
Nevertheless such modification will not change the general form of the model but the materials constant M.

Keywords: ZnO thin films; RF magnetron sputtering; Optical waveguide; X-ray diffraction.
Rutherford backscattering (RBS) is a standard technique in the analysis of materials, which is used for quantitative compositional analysis of thin films, such as layered structures, defect distribution and quantitative compositional measurements of surface impurities of heavy elements on substrates of lighter elements, including impurity profiles, damage depth profile, surface peak, and lattice location of dopant atoms.
It was found from the measured results that the indexes refractive of the films are less than of the bulk materials and under the condition of lower sputtering pressure, the indexes refractive of ZnO films is more closer to bulk crystal Refractive index (no = 1.98, ne = 2.00 at a wavelength of 633 nm) as the thickness of ZnO films gradually increase.

Once there is an oil spill accident, emergency command center gathers the physical, chemical materials of oil spill firstly, and to know the environmental sensitive area of this oil area, to gather real time and historical sea state, weather and hydrological data.
Physical method is applicable to a large amount of oil or oil emulsification, you can use mechanical equipment installed on emergency vessel to recycle oil, or using some absorbing materials; chemical method is applicable to a small amount of oil, the chemical agent includes dispersing agent, poly oil agent, fuel thickener, oil absorbent, etc; after preliminary oil recycling, under the condition of a small amount of oil, you can use biological method, but this method would take a long time.
It would absorb oil from water surface based on the flow characteristic of oil and oil-water mixture, the density difference of oil-water and materials’ absorbability to oil, oil-water mixture. 4) Oil absorption felt.

Introduction
Adhesion refers to an interface's capacity to resist mechanical separation, which describes a
property of material interfaces.
M is the film's biaxial modulus and is equal to E/(1-ν) for the bulk, polycrystalline material, where E is Young's modulus.
Equation (2) also predicts that a plot of hp vs 2h will be a straight line for a linearly elastic material, with the intercept proportional to residual stress in the film and the slope to the film modulus. 43 2 2 1)( − − += ahkhakhp (2) Results and discussion Measuring apparatus fabrication.
