The contributions in this volume cover methods for removal of particle contaminants on surfaces. Several of these methods are well established and have been employed in industrial applications for a long time. However, the ever- higher demand for removal of smaller particles on newer substrate materials is driving continuous development of the established cleaning methods and alternative innovative methods for particle removal. This book provides information on the latest developments in this topic area.

Rajiv Kohli

Dr. Rajiv Kohli is a leading expert with The Aerospace Corporation in contaminant particle behavior, surface cleaning, and contamination control. At the NASA Johnson Space Center in Houston, Texas, he provides technical support for contamination control related to ground-based and manned spaceflight hardware, as well as for unmanned spacecraft. His technical interests are in particle behavior, precision cleaning, solution and surface chemistry, advanced materials and chemical thermodynamics. Dr. Kohli was involved in developing solvent-based cleaning applications for use in the nuclear industry and he also developed an innovative microabrasive system for a wide variety of precision cleaning and micro-processing applications in the commercial industry. He is the senior editor of this book series “Developments in Surface Contamination and Cleaning”; the first ten volumes in the series were published in 2008, 2010, 2011, 2012, 2013 (Volumes 5 and 6), 2015 (Volumes 7 and 8), and 2017 (Volumes 9 and 10), respectively. The second edition of Volume 1 was published in 2016. Volume 11 and Volume 12 (this volume) are expected to be published in 2019. Previously, Dr. Kohli co-authored the book “Commercial Utilization of Space: An International Comparison of Framework Conditions”, and he has published more than 270 technical papers, articles and reports on precision cleaning, advanced materials, chemical thermodynamics, environmental degradation of materials, and technical and economic assessment of emerging technologies. Dr. Kohli was recognized for his contributions to NASA’s Space Shuttle Return to Flight effort with the Public Service Medal, one of the agency’s highest awards.
