FACULTY NEWS

With support from the National Science Foundation, MIT inaugurates a Summer Institute in Materials Science and Material Culture (SIMSMC). Fifteen faculty members from liberal arts colleges around the country, representing fields from art history to physics, will participate in the first two-week SIMSMC in June 2002. The job of the Summer Institute is to encourage and assist faculty at liberal arts colleges in introducing materials science and engineering to their undergraduate curricula. As an example of how such curricular innovation can be accomplished, archaeological science will be shown to be an effective vehicle for combining materials science and the human sciences. DMSE Faculty involved with the project include Heather Lechtman, Sam Allen, Linn Hobbs, and Dorothy Hosler.

OBITUARY

Paul Gordon, BS 1939, MS and PhD 1949, acclaimed scientist, engineer, and educator, died on June 7, 2001 of an aortic aneuryism. A memorial service was held at the Illinois Institute of Technology on November 2. Dr. Gordon had an impact on scientific community and on U.S. national defense. He had an impact on the Chicago area through the building up of the Department of Metallurgical and Materials Engineering at the Illinois Institute of Technology, where he was a professor from 1949 to 1951 and from 1954 until the time of his death. From 1966 to 1976 he was chairman of the department. Prior this long stint at I.I.T., he was a professor at the Fermi Institute at the University of Chicago from 1950 to 1954.

Dr. Gordon was born in Hartford, Connecticut on January 1, 1918, the middle of three children of Charles and Anna Goldstein. He worked his way through college with many simultaneous jobs (such as doing the laundry of others in the dorms at MIT), attending Wesleyan University for two years and then MIT, receiving his BSc. degree in 1939 and his masters and doctorate in metallurgy in 1949, all from MIT. He married Evelyn Rubin, of Boston, in 1941 and they had two children.

At the beginning of World War II, Paul Gordon volunteered for the Navy, but was rejected, being told that the Navy had no need for metallurgists. It was around this time that he changed his last name from Goldstein to Gordon. Dr. Gordon subsequently taught at M.I.T. and worked as a group leader on the Manhattan Project during the war and was in charge of physical metallurgy for the Atomic Energy Commission at MIT after the war. Over the next decade or so he continued to do research for the Atomic Energy Commission. Raised amid communities of left-wing Jewish intellectuals, both of the Gordons sympathized with progressive political and social causes, actively supporting Henry Wallace for President in 1948. However, there were real dangers during the "McCarthy period," especially for Jewish scientists involved in nuclear research efforts who also had progressive political sympathies—signing petitions supporting Wallace was enough to cast one under suspicion.

Dr. Gordon's career in Chicago comprised dedicated, effective, and acclaimed teaching, extensive service to his department at IIT, research and publishing, and consulting to industry as an engineer and to the courts as an expert witness. His scientific specialties were the deformation and failure of metals as in metal machines, devices, and structures; sub-microscopic phase transformations and property-structure relationships in metals; and , generally, the power, mystery, and effects of the theories of thermodynamics. He published many articles and seminar papers, conrtibuted to numerous books, produced many proprietary scientific reports and results of investigations-well over one hundred total publications. In 1963 his book, Principles of Phase Diagrams in Materials Systems, was published. A Japanese-language edition was published in 1971. He worked in close, productive relationships with many colleagues and students. He conducted some 900 investigations of metals failures—including the devastating collapse of a CTA "L" track support in 1978—from prosthetic implants and devices, to tools, hooks, fasteners, automotive parts, appliances, jacks, ladders, presses, pressure vessels, and welded parts, to cranes, airplanes, railroads, bridges, buildings, and other structures. He provided expert court testimony in some 40 cases. He was a scientific consultant to the Ryerson steel company for several decades. Some of his investigations were in the normal, everyday, macrocosmic world of accidents. For example, he investigated the crash of two Sikorsky helicopters, the collapse of a Kmart roof, the crash of a Forest Service DC-3, a failed surgical implant, a failed scaffold, and an exploded transmission in a dragster. On the other hand, the molecular and the subatomic comprised the world where he carried out his research, such as, in 1945, "The Transformation of Retained Austenite in High Speed Steel at Sub-Atmospheric Temperatures," "Edge-Nucleated, Growth-Controlled Recrystallization of Copper" (1955), and "The Mechanisms of Crack Nucleation and Propagation in Metal-Induced Embrittlement of Metals" (1982). Other unpublished, commissioned reports cover a wide range, from the magnetic susceptibility of uranium alloys to the cracking of stainless steel mutators in ice cream machines.

Among his many academic and scientific honors, there were two he was most proud of. In 1957 he received the Mathewson Gold Medal, awarded by the AIME (American Institute of Mining, Metallurgical and Petroleum Engineers) for the best scientific paper of the previous three years. In 1993 he received the Albert Easton White Distinguished Teacher Award of the American Society of Metals International. In addition, he was exceptionally dedicated to establishing and maintaining the world-renowned quality of the Department of Metallurgical Engineering at IIT for five decades. Dr. Gordon's colleagues and students considered him to have an unusually brilliant and incisive scientific mind. His journey, from an unprivileged but happy childhood in a family with no money but three lively brainy children, to become a patriarch of a major scientific community in academia, is inspiring.

Paul Gordon is survived by his son, Dana Gordon, of New York City, and his daughter, Janelle Higgins, of Fairfax, California, and by three grandchildren.

UHLIG LAB SEMINAR 29 November 2001 Chipman Room 8-314 10:00 am
COMPOSITION, STRUCTURE AND ELECTROCHEMICAL PROPERTIES OF ANODIC OXIDES ON COPPER
Hans-Henning Strehblow
Institut fuer Physikalische Chemie Heinrich-Heine-Universitaet, Duesseldorf, Germany

ABSTRACT A short introduction to XPS and ISS studies on the composition of passive layers on pure metals and binary alloys is given. As an example the passive layer on Cu is discussed more in detail. The formation of OH adsorption layers and the initial and later stages of anodic oxidation have been studied on Cu(111) single crystal surfaces with STM. In 0.1 M NaOH Cu forms OH- adsorption layers for E > - 0.67 V (SHE) whereas oxide formation occurs at E > - 0.25 V. The adsorption of OH- and oxide formation can be followed in situ with STM. At sufficiently negative potentials even time-resolved investigations become possible. OH adsorption goes along with a surface reconstruction. Oxide formation starts with small non-crystalline grains which develop into oxide crystals in a later stage. These details are discussed on the basis of previous results on the chemical composition of the passive layer in alkaline solutions and its semiconducting properties obtained from XPS, UPS, and electrochemical and photoelectrochemical investigations.
