I read Maureen Rouhi’s “Minimalist Chemistry” article with interest (C&EN, Oct. 3, 2011, page 41). The more I read the article, however, the more I thought, “What is so new with the procedures being described?” The techniques of microscale chemistry have been being used for years in the U.S.
I personally have presented three papers at ACS national meetings on this subject. At North Central College in the early 1980s we were using plastic well plates with 12 wells in our introductory courses. There are many advantages to using the well plates for electrochemistry, acid-base, qualitative screening, and many other tests. Some instructors in our DuPage County High Schools are even using the 96-well plates.
In the early 1980s, the National Microscale Center at Merrimack College began presenting National Science Foundation workshops in organic, general, and inorganic chemistry. These one-week workshops were well received and helped many educators incorporate the techniques in their classes. A literature search of the use of small-scale chemistry reveals that instructors were beginning to use the smaller scales in their classes and also cut quantities in the early 1930s. John Yoe of the University of Virginia published several papers in the 1930s. I have even attended ACS national meeting sessions where the presenters brought adequate supplies for the attendees to participate in the small-scale reaction demonstrations.
I am happy that Japanese educators are being creative and continuing to teach under stressful situations, but to publish their techniques as new or unique is not quite true. I feel that the author should have mentioned some of the earlier work done in the U.S. for a number of years.
