1 The researchers think that silicate perovskite — the more prevalent source of iron in the lower mantle — should also exhibit the spin transition zone, although they have not tested it yet.

2 In this article, the crystal structure of perovskite photocatalyst is presented.

3 The general methods of making perovskite functional ceramics are solid phase reaction and oxalate decompound.

4 As we know, the studies of perovskite manganite oxides have attracted much renewed attention in strongly correlated electron system since the discovery of colossal magnetoresistance(CMR) effect.

5 Perovskite type oxide material, piezoelectric element using the same, liquid discharge head and liquid discharge apparatus, and manufacturing method.

6 In this study, LaNiO3 perovskite catalysts were prepared by citrate method and used for carbon dioxide(CO2) methanation.

7 More recently, the perovskite manganite compounds, A1-xBxMnO3 have received much attention because of their gigantic magnetoresistance (GMR) and charge ordering properties.

8 Single crystals of sodium tungsten bronzes with cubic perovskite structure were grown by fused sale electrolysis. The crystals have a metallic conducting behavior.

9 The pattern of XRD illustrated that the pure perovskite tetragonal had been obtained for all samples.

10 Perovskite oxide th in films and heterojunctions have been fabricated by laser molecular beam epitaxy controlled in atomic scale.

11 Purpose - To synthesise calcium titanate with a perovskite structure as an anticorrosion pigment for metal protecting paints.

12 It is very different to fabricate pure perovskite phase materials without the appearance of pyrochlore phase in lead based ferroelectric relaxors studies.

13 The Ni catalysts were obtained in situ during the reaction from the oxides as the precursors in which nickel species were homogeneously incorporated in the perovskite structure.

14 XRD showed that both of the PZT films have perovskite structure. The one on LNO bottom adopts(100)preferred orientation and the one on LNO/LSTO bottom adopts random orientation.

15 The high sustainability against coke formation may be partly due to the mobile oxygen as well as due to the presence of alkaline earth metals in the perovskite supports.

16 Combined red mud phase is mainly composed of quartz and calcium aluminum melilite, followed by albite, andradite garnet,(www.Sentencedict.com) and perovskite garnet.

17 XRD analysis of these samples indicated this series of polycrystalline samples possess perovskite structure at room temperature.

18 The XRD analysis shows that the LSGM samples possess orthorhombic perovskite structure.

19 Considering energy level splitting by public electron in the crystal interface, the response frequency relationship of perovskite in micro-wave range is found out.

20 Chapter 1: The general review of the history and present research situation of the perovskite manganite physics and thin films is given.

21 The results showed that the PST thin films would possess the perovskite phase and excellent ferroelectric properties with proper technology.

22 X — Ray Diffraction ( XRD ) spectra indicate that these compounds are single perovskite in structure.

23 Based on the results from both experimental petrology and mineral physics, scientists have worked out silicate perovskite as the major phase in the lower mantle.

24 In Chapter One, several main magnetoresistance effects and the colossal magnetoresistance effect of perovskite manganites are introduced.

25 Many kinds of well-crystallized nanometer or submicron Ti -based perovskite ceramic powders were already synthesized successfully by sol-hydrothermal method at lower temperatures.
