of this book.

Chemical engineering is a dynamic and ever-growing profession, which is reflected by the variety of scales and topics covered by this book, ranging from education to material science. The purpose of this book is to create a platform for the exchange of different experimental techniques, approaches and lessons, in addition to new ideas and strategies in teaching labo‐ ratory unit operations to undergraduate chemical engineering students. It is recommended for instructors and students of chemical engineering and natural sciences who are interested in learning about different experimental setups and techniques, covering a wide range of scales, which can be applied to many areas of chemical engineering. Fundamental knowl‐

The first section in this book explores new studies in the pedagogy of laboratory unit opera‐ tions to chemical engineering undergraduate students. The second section presents applica‐ tions of various experimental methods and techniques to different areas of interest in chemical engineering, such as kinetic growth of metallic layers, preparation and separation of enantiomeric mixtures, and hydrodynamic characterization of stirred tanks, among others. It is hoped that this book will also appeal to academic and practicing professionals of many
