F. R. Hartleycentric PBL with teacher friendly forms and rubrics includedThis second edition of Project-Based Learning (PBL) presents an original approach to Science, Technology, Engineering and Mathematics (STEM) centric PBL. We define PBL as an “ill-defined task with a well-defined outcome,” which is consisten

Preparation of the Supports,ort on demand. It may not be difficult to arrange for a given particle size to be produced, but once we begin to consider factors such as the distribution of donor sites, then the characterisation becomes much more vague. Thus, when considering the preparation of functionalised supports a great deal

Introduction of Metals onto Supports,ysts involved ion-exchange resins in which a cationic metal complex ion was linked electrostatically to the support, the majority of supported metal complex catalysts involve covalent bonds between the metal and the support. Accordingly, after a brief look at ion-exchange based catalysts, this chapt

Characterisation of Supported Catalysts, wide range of analytical and spectroscopic techniques have been applied to the problem. No one technique can do more than illuminate one facet of the structure. A typical characterisation procedure would involve a careful record of the conditions under which the supported catalyst had been prepared

Dimerisation, Oligomerisation, Polymerisation, Disproportionation and Isomerisation of Olefins and ned with dimerisation, oligomerisation and polymerisation, all of which involve the creation of new carbon—carbon bonds and require catalysts. These reactions, particularly polymerisation, are major commercial reactions, which has spurred interest in looking for new and better catalysts. In describi
