Over the past decade, the research community has been paying particular attention to organic, inorganic and hybrid porous materials, mainly due to the plethora of promising applications offered by such architectures in areas as diverse as (nano)filtration and separation techniques, heterogeneous supported catalysis, template-assisted synthesis of nanomaterials, materials for phonic and thermic isolation as well as patterned nanomaterials for microelectronics and photovoltaics, as previously reported by numerous reviews in the field. This book provides current research on nanopores and nanoporous materials. Chapter One affords a critically selected survey of these elegant approaches toward functional nanoporous polymers and investigates their scope and limitations. Chapter Two focuses on the recent development on the nanoporous Montmorillonite clay and metal nanoparticles stabilisation on the clay by different procedures and their catalytic applications for fine chemicals synthesis. Chapter Three presents an overview of the developments in soft nanoporous organic materials by self-assembly of peptide, polyamide and polyimide moieties. Chapter Four examines nano-drilling processing with transmission electron microscope (TEM).
