Nobel laureate to lecture at Ontario’s newest university April 21, 2004 Oshawa, Ont. - Dr. John C. Polanyi, Nobel laureate in Chemistry (1986), and one of Canada’s most distinguished scientists, will deliver a public lecture on May 6 at Ontario’s newest university, the University of Ontario Institute of Technology. The Faculty of Science’s inaugural Distinguished Lecture, “ How Discoveries Are Made and Why It Matters ,” is an enlightened presentation by Dr. Polanyi based on his talk as part of a Canada-Sweden centennial celebration of the Nobel Prize held at the University of Toronto in 2001. In this inspiring discourse, Dr. Polanyi will share his valuable experiences and perspectives on discovery and the world of science. Dr. Polanyi was awarded the 1986 Nobel Prize in Chemistry for developing a new field of research in chemistry – reaction dynamics – which has provided a much more detailed understanding of how chemical reactions take place. Dr. Polanyi studied at the University of Manchester, England, where he obtained his B.Sc. in 1949, a MSc in 1950, a PhD in 1952, and a DSc in 1964. From 1952-1954 he was a Postdoctoral Fellow at the National Research Council Laboratories in Ottawa, and Research Associate at Princeton University from 1954-1956.

HPS280 History of Science Professor John C. Polanyi A Brief Biography Prof. John C. Polanyi is the son of renowned chemist and scientific philosopher, Michael Polanyi. Prof. J. C. Polanyi completed his PhD at Manchester University in England. He went on to take postdoctoral fellowships at the National Research Council in Canada (1952-54) and then Princeton University (until 1956). He returned to Canada in 1956 to become a lecturer at University of Toronto and is currently a faculty member in the Department of Chemistry. In 1986 he received the Nobel Prize in Chemistry, sharing the prize, worth just over $400,000 Cdn., with Dudley Herschbach of Harvard University and Yuan Lee of the University of California at Berkeley. Prof. Polanyi began the research, for which he received the Nobel Prize, soon after he came to Toronto in 1956. He was interested in analyzing the motions and distribution of energy of the molecules formed during collisions resulting from chemical reactions in gases and at surfaces. In addition to the recognition afforded him by the Swedish Academy of Sciences (SAS - it is the SAS from whom laureates receive official news of their prize), Prof. Polanyi has also been made a Companion of the Order of Canada, a Fellow of the Royal Societies of Canada and London, and the National Academy of Sciences in the United States.

Polanyi , and Duncan Rogers Department of Chemistry, University of Toronto, Toronto, Ontario M5S 3H6 Canada This is an abstract for a presentation given at the Eighth Foresight Conference on Molecular Nanotechnology There will be a link from here to the full article when it is available on the web. Electron- and photon-induced reaction of chlorobenzene (ClPh) [ref. 1], 1,2-dichlorobenzene (1,2-diClPh) and 1,4-dichlorobenzene (1,4-diClPh) [ref. 2] adsorbed on silicon (Si(111)7x7) has been shown by Scanning Tunneling Microscopy (STM) to result in 'Localized Atomic Reaction' (LAR), imprinting Cl as chemically-bound Cl-Si on the surface. For the ClPh adsorbate, voltage pulses of -4V from the STM tip served to demonstrate LAR restricted to the region of electron impact. Delocalized electron impact, customarily used in this laboratory, imprinted the pattern of 'parent' ClPh(ad) on the surface as 'daughter' Cl-Si. The imprint was found to be on the same area of the unit cell as the parent ClPh(ad), but at an
