Summer Internship Program Seeking Applicants The Division of Analytical Chemistry of the American Chemical Society is seeking applicants for the 1987 summer internship program. The program is aimed at introducing talented undergraduates to modern analytical chemistry. Students chosen to participate will be employed by industrial, government, or academic analytical laboratories, where they will carry out various phases of fundamental or applied research. Participating laboratories agree to hire one or more students during the summer. Applicants are screened and evaluated by the division's Professional Status Committee. Applications and reference letters of the most qualified students are sent to several participating laboratories. These organizations then select those individuals most suited to their needs. The Professional Status Committee acts as a broker, soliciting applications from both students and organizations. Salary and details of employment are negotiated between the organization and

the undergraduate student. To qualify for the program, students must have completed at least two years of college, preferably including an instrumental analysis course or its equivalent, and must have an interest in analytical chemistry. Ideally, students should be attending a fouryear college and be between their junior and senior years at the start of summer 1987. The Analytical Division will also accept applications from college seniors graduating in 1987 who have specifically demonstrated their interest in analytical chemistry by applying to graduate school with the intention of majoring in that area and from current graduate students in analytical chemistry. The deadline for receipt of student applications is Feb. 15,1987. Additional information and student application forms can be obtained from R. A. Osteryoung, Chairman, Professional Status Committee, ACS Division of Analytical Chemistry, c/o Department of Chemistry, State University of New York at Buffalo, Buffalo, N.Y. 14214. For the 1986 summer internship program, 53 completed student applications were received. Some were rejected on the basis of low grade point average, insufficient background in analytical chemistry, or restrictive geographic requirements. Efforts were made to place 39 students. Nineteen organizations initially indicated an interest in participating in the program. Of these, 10 placed one or more students, five were obliged to withdraw for budgetary reasons, and four were unable to make contact with an appropriate student. Eventually, 14 students were placed with 10 different organizations. Not all of the students who received offers accepted; a number had found positions on their own or were otherwise committed for the summer.

Newly Elected Division Officers for 1987 Four new officers of the Division of Analytical Chemistry of the American Chemical Society were elected recently. The current chairman is Mary Kaiser of Du Pont's polymer products department. The 1987 chairman-elect is Roland Hirsch. Hirsch attended Oberlin College and the University of Michigan and joined the faculty of Seton Hall University in 1965. His research has been primarily in ion exchange and chemometrics. His publications have covered topics in chromatography and liquid membrane ion-selective electrode potentiometry, analysis of variance, factor analysis, and topological analysis. He served as the secretary of the division from 1980 through 1983 and has been a member of the advisory board of ANALYTICAL CHEMISTRY. Hirsch

Society Conference in Cincinnati, Ohio, in September. The award is sponsored by Mettler Instrument Corporation to recognize and encourage individual achievement in the field of thermal analysis. Wiedemann studied at the College of Applied Technology, Kôthen, G.D.R., and at the University of Berne, Switzerland. He is responsible for special applications at Mettler Instrumente AG in Greifensee, Switzerland, including programs involving thermal analysis in archeology, historic objects, and mineralogy. He helped develop the first Mettler thermal system, the TA1, introduced in 1964, in addition to a number of subsequent thermal products.
CHEMRAWN IV An international conference and workshop entitled "Modern Chemistry and Chemical Technology Applied to the Ocean and Its Resources" will be held during the week of Oct. 4-9, 1987, at the Keystone Conference Center, Keystone, Colo. The conference is the fourth in the CHEMRAWN (Chemical Research Applied to World Needs) series, sponsored by the International Union of Pure and Applied Chemistry. One hundred scientists will participate, with 50 drawn from the pure and applied chemistry
community and 50 from the marine chemistry community. Five topic areas will be discussed at the meeting: free-radical chemistries, reactions at marine particle surfaces, seawater system models, and air-sea and sediment-sea interface chemistries. Cochairmen of the program committee are Allen J. Bard of the University of Texas at Austin and Edward Goldberg of the Scripps Institution of Oceanography. Derek W. Spencer of the Woods Hole Océanographie Institution is chairman of the organizing committee.
For Your Information Researchers have discovered a way to increase the sensitivity of nuclear magnetic resonance spectrometry (NMR) by a factor of 10,000, according to the National Science Foundation. The new technique, developed by a team headed by John S. Waugh at the Massachusetts Institute of Technology, requires cooling of samples to a temperature approximately 0.01 Κ above absolute zero.

The market for biosensors will grow from $8 million (1985) to $17 million by 1990 and to $200 million by the year 2000, according to a newly re leased report, "Biosensors and Chemi cal Sensors" (C-053, $1750), by Busi ness Communications Co., Inc. (9 Via duct Rd., Stamford, Conn. 06907). According to the company, the most commonly used biosensors are enzyme electrodes. Other classes of biosensors discussed in the report include tissuebased sensors and those based on transistors or other microelectronic components. The Integrated Sensors Center has been established at the University of California at Berkeley with a fiveyear grant from the Industry-Univer sity Cooperative Research Center pro gram of the National Science Founda tion (NSF). Other funding will be provided by industrial firms and other organizations that will play an active role in the center's research. The cen ter is expected to become self-sustain ing through industrial memberships within five years. According to NSF, the types of devices to be studied at the center include sensors that "deter mine blood-flow rates, pressure levels in automobiles, moisture in home heating systems, acceleration in air craft, and chemical content of poten tially dangerous substances."
