Chemical Engineering in Medicine and Biology

'lbere is much discussion today concerning "Bioengineering" (or "Biomedical Engineering"). It is not exactly clear what these names signify, particularly in chemical engineering. Some have suggested retreading the old war horse "Biochemical Engineering" (or was it "Biomedical Chemical Engineering). In an effort to demonstrate the on-going activities of chemical engineers in the life science area, we accepted the invitation of the Industrial and Engineering Division of the American Chemical Society to organize the 33rd Annual Chemical Engineering Symposium. We decided to call the symposium, Chemical Engineering in Medicine and Biology, and hence avoided the problem of having to decide which "bio" prefix to use. Many chemical engineers in the academic and industrial world were contacted. From these contacts and a good deal of publicity arose the Symposium. The two-day meeting was held at the University of Cincinnati in the Losantiville Room of the Student Union Building on October 20-21, 1966. Twenty-one papers were presented on topics relating chemical engineering to medicine and biology. Tile papers were representation al of the scope of the activities across the country with presenters coming from Washington, California, Massachusetts, New York, South Carolina, Wisconsin, Iowa, Pennsylvania, Michigan, Indiana and Texas. TOpics ranged over blood flow properties, diffusion in blood phenomena, ix INTRODUCTION X mass transfer in the eye, artificial kidney analysis, separation of bacteria by ion exchange, mathematical modeling of drug distribution, carbon dioxide respiration, photosynthetic kinetics, water in frozen tissues, electrophoretic separation of proteins, and outerspace re search on life support systems.
