Whereas your degree of selecting and tackling more challenging questions will each be included in the outcome, such a batch is due within a week from the completion of a chapter. You will then have access to solutions in Dyson 213 by presenting a picture I.D.David N. Rahni is Professor of Analytical Chemistry and, the founder and former Director of Graduate Program in Environmental Science at Pace University, Pleasantville,New York. In addition, he serves as an adjunct professor in both the LL.M. Environmental Law Program at the Pace University School of Law, and the Department of Dermatology at the New York Medical College. He is the 1999 Chair-Elect, and 2000Chair of the American Chemical Society’s New York Section. He was selected the 1996 Distinguished Scientist by the American Chemical Society’s Westchester Section. During 1993-94, he was J. William Fulbright Senior Research Scholar at the Technical University of Denmark (DTU) and visiting professor at the University of Oxford, UK. He was also awarded a visiting professorship to DTU, Denmark by the Royal Danish continuedChemistry 111 Lecture Outline page 4Research Academy for the summer 1994, where he offered a three-day workshop on surface characterization methodology. In the past, he has served as an adjunct professor of chemistry at Manhattanville College, has held visiting scientist positions with the IBM Thomas J. Watson Research Center and Ciba-Geigy Research Division, and has either been a visiting professor or given extended lectures at the II University of Rome, the University of Florence, National University of Mexico, Universities of Southampton, Leeds, Loughborough, London, Copenhagen, and the Danish Orsted Institute. He has also served as a visiting United Nations TOKTEN Scholar in the third world, presenting lectures and assisting in curriculum development in, among others, Tehran, Guilan, and the National Universities of Iran (summer 1992, and 1995). He has provided consultationservices to many industries, and served extensively as expert witness on legal matters. Heis versed in the challenges faced by the higher education in the new millenium.Professor Rahni, has earned his Ph.D./Postdoctoral studies in Analytical Chemistryin Professor G.G. Guilbault’s research laboratory at the (LSU) University of New Orleans(1985-86), his M.S. in Chemistry at Eastern New Mexico University (1980), and his B.Sc. in Chemistry at the National University of Iran (1979). He has published or presented extensively (~one hundred twenty) in such diverse fields as immobilized enzyme electrochemical sensors for clinical, environmental and industrial assays,
