The purpose of this volume, therefore, is to collect state -of- the-art procedures for construction and design of nanoparticles and porous materials, where their applications might be most appropriate To that end, synthesis and characterization procedures are presented The ultimate test is their practical utilization in world" environments that exist at the gas and liquid interfaces of these materials. ..
