chemical principles of industrial proc esses. They covered such things as catalysts and equilibrium and how these variables can be manipulated to boost yields and ultimately improve the economics of a process. Later, industrial officials developed the ideas behind the large-scale technology in volved in the processes. For example, a Cyanamid official explained how the production of diphenylamine had pro gressed from an autoclave process to a vapor phase technique. These classroom-style meetings were then followed by plant visits to see the actual equipment used in vari ous processes. After the tours, plant managers dis cussed economic considerations of the processes. They covered raw ma terial costs, plant depreciation, and profit margins. Methods of distribut ing products, effects of technological advances on cost, human relations, and social implications of the plants were also talked about. When the formal institute program was completed, teachers and company officials evaluated the three-day ses sion. In general the group felt that the program was well worth the effort. The teachers said it gave them a chance to see fundamental principles of chemistry in use and a better under standing of the economics of the chemical industry. Some of the teachers were sur prised at the low profit ratios of the industry and the extent of overcapac ity. They said that they had not been exposed to this important phase of the industry until this time. Also, in meeting industry scientists face-toface, they had gained a knowledge of the varied activities in chemistry to help them in career guidance. One teacher found it difficult to pinpoint the benefits he had derived from the program, but he concluded that teachers could hardly attend the sessions without gaining an insight into the chemical industry that would be reflected in their classrooms in the future. The pilot institute was sponsored by the New York Chemical Industry Council in cooperation with Rutgers University. Dr. Harvey R. Russell, manager of education services at American Cyanamid and director of the institute, hopes that this year's program will inspire other colleges and universities to try similar programs with the industries in their areas.
Cornell's Materials Science Center Adds Analytical Labs A new facility that will emphasize ul tratrace analysis of high purity mate rials has just been completed at the Materials Science Center (MSC) of Cornell University, Ithaca, N.Y. The MSC labs will establish a lead ing research center devoted to trace analysis, says its director Dr. George H. Morrison. Not only does it have full-time chemists who are providing specialized analyses for MSC projects, it also has graduate students and post doctoral fellows working on research in trace methods of analysis. Among the many ultratrace tech niques now used at the labs are acti vation analyses, made in conjunction with Cornell's TRIGA reactor, spark source mass spectroscopy, emission spectroscopy, flame photometry, x-ray fluorescence, and various wet chemical methods. Thus, Dr. Morrison points out, students at the center gain expe rience in all areas of trace analysis. They also benefit from their contacts with scientists from the university de partments that are doing research on materials. A unique feature of the new labs is a solids mass spectrograph. This in strument has many novel refinements to make it more applicable for analyz ing high purity solids. It will provide electrical as well as photographic de tection. MSC Activities. Cornell's Materials Science Center is an interdisciplinary laboratory set up to promote research and training in all phases of the sci ence of materials. Its programs are supported by funds from the Ad vanced Research Projects Agency as well as the funds granted by other agencies and institutions for MSC re search. Currently, the departments of chemistry, engineering physics, ma terials science, and physics are en gaged in these projects. Some indi vidual members of the geology and electrical engineering staffs are also participating. Present research emphasis at the center is on solid state physics, with roughly 507c of the present staff work ing in this field. The primary effort is on physical processes rather than on specific detailed systems. MSC ex pects to develop its programs, exploit ing advances in solid state physics, chemistry, and mathematics for under standing and improving materials. MSC's broad objectives are:
• To raise materials research to the highest professional level by improv ing equipment, facilities, and space. • To produce scientists with greater perspectives in the broad field of ma terials and with a higher level of so phistication in using modem equip ment. MSC will provide funds to buy some badly needed major equipment for individual investigators. And it also expects to help finance a new physical sciences building.

BRIEFS More foreign students, faculty mem bers, and scholars were in the U.S. on educational assignments last year than in any previous year, according to "Open Doors 1962," just published by the Institute of International Educa tion, 800 Second Ave., New York 17, N.Y. The annual survey on interna tional exchange programs also indi cates that more U.S. students and faculty members were abroad for edu cational purposes.
Applications from young faculty members and graduate students in terested in continuing their study and research in the Soviet Union for all or part of the 1963-64 academic year will be accepted by the Inter-Univer sity Committee on Travel Grants, In diana University, Bloomington, Ind., through Nov. 16, 1962. Persons in all fields of study are encouraged to apply. Funds are available to cover all or part of the exchange partici pants' expenses, including family main tenance. For further information, write to deputy chairman Stephen Viederman of the committee.
Northeastern University has started construction of a new $2.2 million life sciences building on its Boston, Mass., campus. The structure will house classrooms, lecture halls, research and instructional labs, as well as the uni versity's new College of Pharmacy.
The Buhl Foundation of Pittsburgh, Pa., will support three international conferences on materials to be held in Pittsburgh in alternate years, starting in 1963. Dr. Edward R. Schatz, dean of research, Carnegie Institute of Technology, will direct the meetings.
