PREFACE for the Third Edition.
There have been already 2 Editions of this book, Edition 1 (2002), Edition 2 (2010). Both these editions are out of print, but there is still ongoing interest to the subjects addressed in this book. We have decided to make the new Edition (3) instead of just printing additional copies of the Edition 2 for the few reasons.
Whereas theoretical background of these methods remains practically unchanged, many important papers have been published since last Edition publication, mostly on the applications of these methods. We are aware of 77 papers published by just users of our instruments. We have published several more papers by our own, bringing total number to 33. However, it is our instruments users’ contribution dominates sections that we have added to this new Edition. As a result Edition 3 exceeds previous Edition 2 by 25% and about 100 new references in bibliography...Read more
PREFACE for the Second Edition.
“Ultrasound for characterizing colloids” was first published in 2002. We decided to work on the second edition after two print runs were sold out and the book became unavailable. By the beginning of 2008, we gathered substantial justifications to prepare a new edition of the book instead of running an extra print of the first edition.
First of all, there were about 40 papers published by users of our instruments in various scientific journals. There was, in addition, about a dozen of our own papers and several papers published by other scientists in the field. These papers demonstrated the wide spectrum of applications for characterization methods by ultrasound..Read more
PREFACE for the First Edition
The roots of this book go back twenty years. In the early 1980’s Philip Goetz, then President of Pen Kem, Inc., was looking for new ways to characterize -potential, especially in concentrated suspensions. His scientific consultants, Bruce Marlow, Hemant Pendse and David Fairhurst, pointed towards utilizing electroacoustic phenomena. Several years of effort resulted in the first commercial electroacoustic instrument for colloids, the PenKem-7000. In the course of their work they learned much about the potential value of ultrasound and collected a large number of papers published over the last two centuries on the use of ultrasound as a technique to characterize a diverse variety of colloids. From this it became clear that electroacoustics was only a small part of an enormous new field.
Unfortunately, by that time Pen Kem’s scientific group broke apart; Bruce Marlow died, David Fairhurst turned back to design his own electrophoretic instruments, and Hemant Pendse concentrated his efforts on the industrial on-line application of ultrasound. In order to fill the vacuum of scientific support, Philip Goetz invited me to the US motivated by my experience and links to the well established group of my father, Prof. Stanislav Dukhin, then the Head of the Theoretical Department in the Institute of Colloid Science of the Ukrainian Academy of Sciences..Read more
