EAS Award Nominations The Eastern Analytical Symposium (EAS) requests nominations for its 1992 awards in the fields of analyti cal chemistry, near-IR spectroscopy, chromatography, and magnetic resonance. Each of these awards recog nizes an individual who has helped to shape those re spective fields. Award winners will be presented with a plaque at the November 11—15 meeting in Somerset, NJ. In addition, the winner of the Award for Achieve ments in the Fields of Analytical Chemistry will receive a $1000 stipend. Nominations, consisting of a biographical sketch and a letter that specifies the nominee's accomplishments, should be sent to Chair, EAS Awards Committee, EAS Inc., P.O. Box 633, Montchanin, DE 19710-0633. Dead line is August 1.
1992 Bomem-Michelson Award The Bomem—Michelson Award is given annually at the Pittsburgh Conference to a scientist who has advanced the techniques of vibrational, molecular, Raman, or elec tronic spectroscopy. Contributions may be theoretical or experimental. The award consists of a medal and $2500. Nominees must be at least 37 years of age and active ly working. Nominating and seconding letters, a curricu lum vitae, and descriptions of specific research efforts should be sent to William Fateley, Department of Chem istry, Kansas State University, P.O. Box 688, Manhat tan, KS 66502 (913-532-6298). Deadline is May 1.

Graduate Student Symposium The 9th annual Graduate Symposium at the State Uni versity of New York at Buffalo will be held May 22-23. This event offers graduate students from any university a chance to present their research to an audience from the academic and industrial sectors. This year, for the first time, the proceedings will be published. Attendance is free, and the cost of two luncheons, a reception, and accommodations is covered by donations. This year's symposium will also feature talks by
M. Bonner Denton, University of Arizona, and Stephen Kaye, Oak Ridge National Laboratory. In addition, Roland Hirsch from the National Institutes of Health will conduct a workshop on proposal writing. An employ ment clearinghouse will also be held. For more information, contact JoAnn Zagrobelny, Chemistry Dept., Acheson Hall, SUNYAB, Buffalo, NY 14214 (716-831-3615, Bitnet: V097MXM7@UBVMS).
Super Transistors A team of researchers from Sandia National Laborato ries and the University of Wisconsin—Madison reports that they have developed transistors made with new high-temperature superconductors. These transistors could offer higher speeds, reduced noise, lower electrical loss, and higher efficiencies for applications such as electronic communications and signal processing than do current devices. The new transistors, labeled superconducting flux flow transistors (SFFTs), are described as the supercon ducting analogue of the commonly used field-effect tran sistor (FET). According to the researchers, the SFFT is the first transistor constructed entirely with hightemperature superconducting materials. The SFFT output voltage is controlled by changing input current (as compared with an FET, whose output current is controlled by varying the input voltage). In put current passes into a control line which, acting like a gate, changes the magnetic field in the active region of the device. These variations modulate the output volt age, providing gain at very high frequencies. The best material found to date for the SFFTs are the thalliumbased superconductors, which retain superconductivity up to 125 Κ and demonstrate high critical currents. The Sandia—Wisconsin team has already built a num ber of circuits with their superconducting transistors, including amplifiers, oscillators, phase shifters, and mixers. The most promising applications, they say, are in microwave and millimeter-wave circuitry.
