We acknowledge that as understanding expands, the number of unknowns
also grows. We hope this book will help industrial and academic scientists,
chemists, and engineers who are performing fundamental and applied
research attain lucid understanding of foaming mechanisms and materials
that will lead to great achievements. The volume can also be used as a
textbook at the graduate level and a reference book for undergraduate
courses on foams. We believe this book will generate a tremendous interest
in developing new processes, technologies, and applications in the area of
manufacturing foams.
