โฆ Synopsis
An article in the April 1992 issue of Science Watch lists the top 25 Departments in the area of Chemical Engineering based on the number of citations per publication recorded in the ISI Science Indicators Database for the period 1984-1991; only those institutions publishing more than 70 articles, reviews and notes in journals covered in the chemical (engineering) subsection of Current Contents/Engineering, Technology and Applied Science have been included in the survey. It should be noted by those about to scurry off to consult Current Contents that Applied Catafysis is included in those pages but Journal of Catafysis is not.
There are a number of surprises in the listing in addition to the names of institutions which would be expected to feature. The following is a listing in order of citations per paper; the figures in brackets are in turn the total number of papers in the period, [1984][1985][1986][1987][1988][1989][1990], the total number of citations in that period and the number of citations per paper. (It should be noted that the average number of citations per paper for all the papers listed in the index was 1.8.)
