Applications of co-crystals are varied and in the past decade this area of research has received tremendous attention from academia and industry alike. This book not only focusses on the effective design of co-crystals based on hydrogen- or halogen-bonds, but it also provides insights into practical synthesis and characterization of co-crystals. It also highlights the more recent but increasingly important practical applications of co-crystallization in, for example, pharmaceuticals, energetic materials, and separation technology. Postgraduate students and researchers new to applied co-crystal research and crystal engineering will find this a useful resource.
