Background of This Series

Dispersing Powders in Liquids, by Ralph D. Nelson, Jr. (Elsevier Science Publishers B.V., 1988) was originally published to accompany courses that the author taught to industrial technologists over a two-decade period. The book was quite popular. All copies of the first edition were sold, the publisher re-issued it in 1993, and most of the second printing were also sold. In 2001 the publisher gave the copyright back to the author, who has now given Educational Resources for Particle Technology a license to post an updated version on the Web as a series of articles.

Ralph D. Nelson, Jr. earned a BA in chemistry from Colby College and a PhD in physical chemistry from Princeton University and was then appointed as an NSF-NRC Postdoctoral Fellow at the National Bureau of Standards for two years. For seven years he taught physical chemistry at Georgetown University, Middlebury College, Brown University, and West Virginia University, then earned an MSE in chemical engineering at West Virginia University.

He joined the DuPont Company in 1974 and spent twenty-five years in technical assistance to manufacturing and as an internal consultant in particle technology, retiring in 1998 as a Senior Research Associate. He wrote Dispersing Powders in Liquids (Elsevier, 1988 and 1995) and has taught continuing education courses at the Center for Professional Advancement, the Univ. of Florida, and within DuPont. He is now the managing editor of Educational Resources for Particle Technology -- a new venture in the on-line, just-in-time, free-of-charge delivery of tutorials in particle technology.
