This book was released on 2024-06-19 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cerium - Chemistry, Technology, Geology, Soil Science and Economics illustrates the global interest in rare earth elements. The first section on potential new mining resources focuses on the global issues of rare earth element scarcity and procurement pollution because of rare earth element ion exchange deposits. The section on the technology and utilization of rare earth elements addresses research on the usage of rare earth elements in emerging technologies involving medicine, digital technology, and chemistry. The research also presents the rapid development of emerging technologies that require rare earth elements and the social issues that arise because of these technologies.

Book excerpt: Cerium is one of the most important lanthanide elements based on its characteristics and wide range of related applications. Cerium is the second element in the lanthanide series, and mostly can be found in either +3 or +4 ionisation states. It can be considered one of the rare earth elements with relatively low toxicity and a lot of biological applications depending on its redox (reduction-oxidation) process between the +3/+4 ionisation states and oxygen storage capability. This book focuses on the cerium compounds such as oxides and silicides, with detailed studies about its structures, characterisations and related applications. Chapter One mainly presents some optical characteristics of stoichiometric ceria nanoparticles whether undoped or doped with some other lanthanide elements. Then, some applications of ceria nanoparticles, such as optical nanosensors and solar cell coaters, are discussed based on optical characteristics of CeO2-x. Chapter Two studies the catalytic activity of cerium dioxide (CeO2) included within nanophase (nanocomposite) metal-oxide systems such as Al2O3/cordierite carriers and prototypes of anode materials for SOFCs (based on stabilised zirconia), within different processes of environmental catalysis. CeO2 increases stability of the Ni-Al2O3 catalysts by suppressing surface carbonisation and enhancing resistance to poisoning by sulphur compounds. Cerium dioxide as a modifying additive within the ZnOCuOCeO2/Al2O3/cordierite catalysts is shown to stabilise their operation in the decomposition of methanol by suppressing surface carbonisation, thereby facilitating hydrogen formation as the target product. In Chapter Three, another cerium-dependent compound cerium silicide (CeSix) and its nanowires were investigated over a broad range of different cerium monolayers on Si(110)-16×2 surfaces via scanning, tunnelling, microscopy and spectroscopy. The growth progress of the CeSix nanowires undergoes a coverage-dependent metal-insulator-metal electronic transition, which has never been found in other rare-earth silicide nanowires. Moreover, the insulating CeSix nanowires have been structurally and electronically studied, without lattice distortions with large Coulomb repulsion energy between the filled and empty surface bands. Thus, the insulating phase of atomically precise CeSix nanowires is an electronically driven phase because of its temperature and structure independence. Chapter Four is mainly concerned with some biological applications of ceria nanostructures through the treatment of diseases characterised by increased oxidative stress levels. This chapter offers a study of consumption and occupational exposures, and consequently its toxicology properties are discussed due to the recent applications of nanoceria as a high priority material for toxicological evaluations.
