• Sommario/riassunto: A selection of papers many of which proved novel and thought-provoking and have had a considerable influence on the development of chemical engineering, chosen by Professor Danckwerts from research work conducted at Cambridge and Imperial College mainly during the years 1950-1954 and 1957-1973. They are divided into 6 sections with linking critical commentaries.
