Gold has traditionally been regarded as inactive as a catalytic metal. However, the advent of nanoparticulate gold on high surface area oxide supports has demonstrated its high catalytic activity in many chemical reactions. Gold is active as a heterogeneous catalyst in both gas and liquid phases, and complexes catalyse reactions homogeneously in solution. Many of the reactions being studied will lead to new application areas for catalysis by gold in pollution control, chemical processing, sensors and fuel cell technology. This book describes the properties of gold, the methods for preparing...

This is a rare collection of papers by leading authorities on addiction recovery. The distinguished list of contributors includes Alan Marlatt, George Vaillant, Stanton Peele, Jaak Panksepp, and Scott Tonigan. Although each represents different theoretical perspectives of addiction and recovery, all see recovery as more than mere abstinence. The first half of this book contains addresses from the Fourth International Meaning Conference, which focused on meaning and addiction. The second half of this volume uniquely focuses on the positive psychology of meaning and spirituality as an answer...

It includes only the parts of Geoffrey's "Historia" that are about Merlin or Arthur, omitting its lengthy histories of other kings, which do not interest today's readers. It breaks up Geoffrey's text into shorter chapters, and it adds...
