• Sommario/riassunto: This handbook and ready reference brings together all significant issues of practical importance for interested readers in one single volume. While covering homogeneous and heterogeneous catalysis, the text is unique in focusing on such important aspects as using different reaction media, microwave techniques or catalyst recycling. It also provides a comprehensive treatment of modern-day coupling reactions and emphasizes those topics that show potential for future development, such as continuous flow systems, water as a reaction medium, and catalyst immobilization, among others.

• Sommario/riassunto: At the turn of the 20th century, colleges and universities in the US (and in many other places) were convulsed with change, a change induced by the creation of the modern set of academic disciplines. Their emergence at that time fundamentally altered how universities were constructed and how they did their business. It is the model on which the academy of the 21st century operates. The contemporary college and university is a rich amalgam of disciplinary and interdisciplinary units, problems, approaches, and structures.
