Produktbeschreibung

LANTHANIDE AND ACTINIDE CHEMISTRY Lanthanides and actinides, also known as "f elements," are a group of metals which share certain important properties and aspects of electronic structure. They have a huge range of applications in the production of electronic devices, magnets, superconductors, fuel cells, sensors, and more. The cursory treatment of these important metals in most inorganic chemistry textbooks makes a book-length treatment essential. Since 2006, Lanthanide and Actinide Chemistry has met this need with a thorough, accessible overview. With in-depth accounts of the lanthanides, actinides, and transactinides, this book is ideal for both undergraduate and postgraduate students in inorganic chemistry or chemical engineering courses. Now updated to reflect groundbreaking recent research, this promises to continue as the essential introductory volume on the subject. Readers of the second edition of Lanthanide and Actinide Chemistry will also find: * New and expanded subject areas including lanthanide enzymes, single-molecule magnets, luminescence and upconversion, organometallic and coordination chemistry; and many more. * Up-to-date information on the myriad modern applications of f-elements * Lists of objectives and learning goals at the start of each chapter Lanthanide and Actinide Chemistry is ideal for advanced undergraduates and graduate students in f-element chemistry, inorganic chemistry, or any related field. INORGANIC CHEMISTRY ADVANCED TEXTBOOK This series reflects the pivotal role of modern inorganic and physical chemistry in a whole range of emerging areas, such as materials chemistry, green chemistry and bioinorganic chemistry, as well as providing a solid grounding in established areas such as solid state chemistry, coordination chemistry, main group chemistry and physical inorganic chemistry.
