An investigation of the influence of synthesis conditions on the crystallite size, lattice parameter and lattice strain of ceriumdioxide nanoparticles synthesised by coprecipitation and sol-gel processes is presented. The effect of initial precursors, precipitation and calcination temperatures, aging time and molar concentrations of precursor solution on particle size and lattice parameter has been studied. The physicochemical characterisation was performed using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), and thermal analysis (TG-DTA). XRD profile indicates the presence of cubic fluorite-structured nanoceria particles. The average crystallite size of the samples determined by Debye-Scherrer formula ranges from 4.2 to 36.9 nm. Lattice parameters vary from 5.37 to 5.44 Å . Lattice strain of the samples was analysed using Williamson-Hall analysis since these relate to imperfections and distortions in the crystal structure. It is found that ceria reduces strain by lattice expansion which is pronounced in lower dimensions.

This chapter is an update of a review published by our group elsewhere in Patai's Series; in addition, in this volume, chapters present the recent advances in the deposition of metals and transition‐metal oxides, all derived from metal enolates. Materials featuring group 3 ‐ 12 elements have attracted great technological and scientific attention during the last decades because of their outstanding chemical and physical properties. They are widely used in industry, including a variety of catalyst supports, coatings, as dielectrics for semiconducting devices, and as sensors.

Thin Film Structures in Energy Applications

State-of-the-art solid oxide fuel cells (SOFC) are among the main candidates for clean energy technology due to their high efficiency, fuel flexibility, low air pollution, and minimal greenhouse gas emission. However, high operational temperature of SOFC is a greater challenge in commercialization of these devices for low cost and portable applications. High temperature operation of SOFC degrades its performance with aging, limits the selection of materials for fuel cell components, and increases the fabrication cost. Thus, there have been enormous efforts to improve the properties of existing materials and develop new materials for SOFC components in order to lower the operating temperature of SOFC. Recent advances in thin film technology have also been utilized to develop new materials with improved properties for SOFC. One of the key components in SOFC is the electrolyte and several research groups are working on developing new electrolyte materials. In this chapter, we will discuss the recent advances in thin film SOFC electrolytes. This extensive discussion includes the evolution of doped ceria, doped zirconia, and multilayer hetero-structured thin film electrolytes. The newly developed nanoscale thin films and multilayer hetero-structures with improved oxygen ionic conductivity will have significant impact on SOFC devices. Introduction Background of Solid Oxide Fuel Cells (SOFC)The latest U.S. energy reviews revealed that more than 80 % of the energy consumed in the world is still produced by non-renewable energy sources such as petroleum, natural gas, and coal [1]. Moreover, it is projected that world energy consumption will grow by 56 % from 2010 to 2040. Therefore, from a long-term energy perspective, clean energy technologies are needed to utilize primary energy
