DOWNLOAD EBOOKIntroduction and Literature Review: Different families of oxide ion conductors and their applications are discussed. Experimental and Characterisation Methods: The synthetic methods and characterisation techniques used throughout this thesis are described. Synthesis, Structure and Transport Properties of Bi2Zr2-xTixO7 Phases: The characterisation of Bi2Zr2-xTixO7 compounds is reported for the first time. An increase in conductivity of 3 orders of magnitude is found for the Zr- rich end member. Bi2Ti2O7, which adopts centrosymmetric space group Fd-3m has been found to be SHG active. Structure Solution of beta-Bi2Sn2O7 and Properties of Bi2Sn2O7 Based Materials: Analysis of synchrotron powder X-ray and powder neutron diffraction data has shown for the first time that beta-Bi2Sn2O7 is not cubic and has a monoclinic structure, most likely in space group Pc. The effect of doping in both Bi2Sn2O7 and Bi2ScNbO7 on their respective conductivities has been explored. Synthesis and Characterisation of Nd2Zr2O7: A range of average and local structural techniques have been used to demonstrate that Nd2Zr2O7 prepared by wet-chemistry routes adopts the fluorite-type structure, as opposed to the pyrochlore structure adopted by samples synthesised by solid state methods. Synthesis, Characterisation, Simulations and Properties of Bi6WO12 and Related Oxide Ion Conductors: We report for the first time details of DFT molecular dynamics simulations to probe the oxide ion conduction pathways in the oxide ion conductor Bi6WO12. Appropriate doping has led to enhancements in oxide ion conductivity. Simulations, Characterisation and Properties of New Bismuth Vanadate Oxide Ion Conductors: DFT molecular dynamics simulations carried out on Bi19V2O33.5 have revealed the O2- migration pathways in this material with exceptional ionic conductivity. The synthesis and characterisation of new doped bismuth vanadates with formula Bi19-xMxV2O33.5-x/2 (M = Ca2+ or Sr2+), also excellent oxide ion conductors, is reported. Overall Conclusions and Suggestions for Future Work: This briefly reviews the conclusions and makes suggestions for further work.

DOWNLOAD EBOOKNano-oxide materials lend themselves to applications in a wide variety of emerging technological fields such as microelectronics, catalysts, ceramics, coatings, and energy storage. However, developing new routes for making nano-based materials is a challenging area for solid-state materials chemists. This book does just that by describing a novel method for preparing them. The authors have developed a novel low-temperature, self-propagating synthetic route to nano-oxides by the solution combustion and combustible precursor processes. This method provides the desired composition, structure, and properties for many types of technologically useful nanocrystalline oxide materials like alumina, ceria, iron oxides, titania, yttria, and zirconia, among others.The book is particularly instructive in bringing readers one step closer to the exploration of nanomaterials. Students of nanoscience can acquaint themselves with the actual production and evaluation of nanopowders by this route, while academic researchers and industrial scientists will find answers to a host of questions on nano-oxides. The book also provides an impetus for scientists in industrial research to evaluate and explore new ways to scale up the production of nanomaterials, offering helpful suggestions for further research.

DOWNLOAD EBOOKMetal Oxide–Based Heterostructures: Fabrication and Applications provides information on synthesis strategies, structural and hierarchical features, morphological characteristics of metal oxide–based heterostructures, and their diverse applications. This book begins with an introduction to the various multidimensional heterostructures, synthesis aspects, and techniques used to control the formation of heterostructures. Then, the impact of synthesis routes on the formation of mixed metal oxide heterostructures and their properties are analyzed. The effect of nonmetal doping, metal doping, and composites of metal oxide heterostructures on the properties of heterostructures is also addressed and that also includes opportunities for optimization of the material’s performance for specific applications. Special attention is given to the surface characteristics of the metal oxide heterostructures and their impact on the material’s performance, and the applications of metal oxide heterostructures in various fields such as environmental remediation, sensing, organic catalysis, photovoltaics, light emitting materials, and hydrogen production. Introduces key principles for metal oxide heterostructures, their properties, key characteristics, and synthesis routes Emphasizes the relationship between synthesis strategies and material performance, including optimization strategies such as tailoring the material’s surface characteristics or structure Discusses metal oxide heterostructures and their application in lighting and displays, energy, environment, and sensing

DOWNLOAD EBOOKFunctional polar oxide materials occupy a very crucial position in modern technology. The polar oxide materials exhibit many technologically important properties like second-harmonic generation, piezoelectricity, pyroelectricity, and possibly ferroelectricity caused by their polar crystal structure. Though the structure-property relationship in polar oxide materials is well studied, the understanding of how the structural building units are joined to form a new polar crystal structure has been less sufficient. A synthetic approach using cations susceptible to second-order Jahn Teller (SOJT) distortion like octahedrally coordinated d0 cations (Ti4+, V5+, Mo6+) and lone-pair cations (Sn2+, Sb3+, Te4+) is successful in preparing new polar oxide materials. We were successful in preparing several new polar oxide materials, Zn2(MoO4)(AO3) (A = Se4+, Te4+) (P21), BiO(IO3) (Pca21), Li6(Mo2O5)3(SeO3)6 (Pmn21), Na2(WO3)3(SeO3)2H2O (P31c), and Na6(W6O19)(SeO3)2 (C2) and other centrosymmetric materials, Li2(MO4)(TeO3)2 (M = Mo6+, W6+) (P21/n). In this dissertation, we report the syntheses, crystal structures, physical properties, functional properties, and understanding of the structure-property relationship of the reported oxide materials.
