Functional 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.

Non-centrosymmetric (NCS) oxide materials are of significant interest because of their functional properties, for example, second-harmonic generating (SHG), piezoelectricity, ferroelectricity, and pyroelectricity. A number of design strategies have been discussed for creating NCS oxide materials. We have focused on using cations susceptible to second-order Jahn-Teller (SOJT) distortion. The distortion can occur in two different types of cations, d0 transition metals (Ti4+, V5+, Nb5+, Mo6+, etc.) and cations with stereoactive lone-pair (Se4+, Te4+, I5+, Tl+, Pb2+, etc.), and results in asymmetric coordination environments. In this dissertation, we report on the syntheses, crystal structures, characterization, functional properties, and their crystal structure-physical property relationships.

Symposium S, "Nanostructured Metal Oxides for Advanced Applications," was held April 1-5 at the 2013 MRS Spring Meeting in San Francisco, California. Metal oxides represent an appealing and assorted class of materials, whose properties cover the entire range from metals to semiconductors to insulators and almost all aspects of material science, chemistry and physics in a very broad application area. In the past few years, progress has been made on the synthesis, structural, physical, and chemical characterization of self-assembled and hierarchically-assembled metal oxide nanostructures that exhibit size-dependent properties. In these proceedings, attention is paid to the synthesis, structural and functional characterization of self-assembled nanostructures and architectures of all metal oxides with application potentials, with particular consideration given to the capability to tailor and control material properties via surface and structural modifications.

Metal Oxide Nanoparticles in Organic Solvents discusses recent advances in the chemistry involved for the controlled synthesis and assembly of metal oxide nanoparticles, the characterizations required by such nanoobjects, and their size and shape depending properties. In the last few years, a valuable alternative to the well-known aqueous sol-gel processes was developed in the form of nonaqueous solution routes. Metal Oxide Nanoparticles in Organic Solvents reviews and compares surfactant- and solvent-controlled routes, as well as providing an overview of techniques for the characterization of metal oxide nanoparticles, crystallization pathways, the physical properties of metal oxide nanoparticles, their applications in diverse fields of technology, and their assembly into larger nano- and mesostructures. Researchers and postgraduates in the fields of nanomaterials and sol-gel chemistry will appreciate this book’s informative approach to chemical formation mechanisms in relation to metal oxides.
