Symposium K, “Nanostructures, Thin Films and Bulk Oxides—Synthesis, Characterization and Applications” and Symposium RR, “Solution Synthesis of Inorganic Functional Materials” were held April 21–25 at the 2014 MRS Spring Meeting in San Francisco, California. Oxide materials from bulk down to nanostructures are used for applications in microelectronics, communications, sensing, energy, catalysis, nanophotonics, and optoelectronics. As the characteristic dimensions of oxide systems shrink into the nanometer range, there are increased technological challenges for synthesis, processing, and characterization to ensure high uniformity, reproducibility, and cost reduction. This symposium proceedings volume represents the recent advances in various areas of deposition, processing, characterization, and integration of functional oxide materials, with particular emphasis on the relationship among the structure, composition, stability and functional properties. The papers are divided into three sections: (1) ZnO Thin Films and Nanostructures, (2) Multiferroics, Magnetism, and Magnetic Materials and (3) Oxide Thin Films and Nanostructures.
