COME WATCH NIST'S FIRST ASTRONAUT LIFTOFF INTO ORBIT! THURSDAY, April 3, 1997, 2 p.m., Green Auditorium, Administration Building NIST engineer Gregory T. Linteris is scheduled to lift off on April 3 as one of two payload specialists aboard the Space Shuttle STS-83 low-gravity science mission. Linteris will conduct fire and combustion research during the 16-day, seven member STS-83 flight. The work--among more than 25 projects in fluid physics, materials science and combustion science scheduled--will be done aboard the Microgravity Science Laboratory, a facility within the shuttle's payload bay that permits scientists to examine the effects of microgravity on specific processes and to use the near-absence of gravity in orbit to perform research that cannot be done on Earth. Linteris is a fire and combustion scientist in the Building and Fire Research Laboratory's Fire Science Division.

NIST 96-97 Colloquium Series WHAT MADE BELL LABS GREAT Thomas A. Heppenheimer, Author FRIDAY, April 4, 10:30 a.m., Green Auditorium, Administration Building What made Bell Labs great? And why is it that the most revered industrial research center of all couldn't stay on top? During the 1930s there was close to zero demand for physicists in industry; yet the invention of the transistor was only a few years away. Mervin Kelly, director of research at Bell Labs, thus succeeded in hiring such recent graduates as William Shockley, Dean Wooldridge, and John Pierce. By offering academic freedom to the best of his scientists, along with the vast resources of the Bell system, Kelly built his lab into an unrivaled powerhouse. The Bell Labs story demonstrates what can be accomplished with an all-out technological assault on a broad domain of activities ripe for innovation. It shows the advantages of working on a grand scale where small improvements can add up to large profits, and it shows the importance of leadership from a visionary director. Bell Labs stuck to a single field--telecommunications--but used its size and privileged market position to explore that field to its furthest recesses. This approach was the key to its dominance--and to why that dominance didn't, and perhaps couldn't, last. P.S. Three of Heppenheimer's 6 books have been alternate selections of the Book-of-the-Month Club! Anyone requiring special assistance should contact Bill Ott, 975-4202. Colloquia are videotaped and available in the NIST Research Library.

Advance Notice Metallurgy Division, Magnetic Materials Group SPIN CONFIGURATIONS AND REVERSAL PROCESSES IN MAGNETIC MESOSTRUCTURES Dr. J. A. C. Bland Cavendish Laboratory, Cambridge, United Kingdom 10:30 a.m., Monday, April 7, 1997, Physics Conference Room (221/Bl65) Structures based on epitaxial magnetic films provide an opportunity to study the magnetic reversal processes under controlled conditions in which both the static spin configurations and field induced domain structures are strongly constrained by the reduced symmetry of the structure. These phenomena are important both for the insights they give into reversal processes in idealized conditions but also in understanding the size dependent behavior of micron scale devices based on thin film structures. Please invite anyone you feel may be interested in this informal seminar. For further information call Bill Egelhoff, 975-2542.

Advance Notice NIST Committee for Women Women's History Month THE EDUCATION OF THE YOUNG WOMAN ARTIST: RENAISSANCE TO CONTEMPORARY Jill Wexler-Greenstein, National Museum of Women in the Arts 2 p.m., Tuesday, April 8, 1997, Green Auditorium, Administration The NIST Committee for Women is proud to present Jill Wexler-Greenstein from the National Museum of Women in the Arts as our Speaker for Women's History Month which we are observing in April. Ms. Wexler-Greenstein will discuss the young woman artist from the renaissance to contemporary times. One artist that will be featured in her talk will be Maria Sibylla Merian, an early entymologist, who travelled to Surinam in 1699 where she studied and painted insects, birds, and plants. The U.S. Postal Service recently issued two stamps that depict two of the more than 70 images Merian created while on this expedition. The National Museum of Women in the Arts was established in Washington, DC in 1987 as the only museum in the world dedicated to recognizing and celebrating the achievements of women artists. Please join the NCW in this presentation to celebrate Women's History Month. For additional information please contact Catherine O'Connell, Vice President, NCW, 975-3123, e-mail: catherine.oconnell@nist.gov.

Advance Notice SPECIAL TOPICS IN STATISTICAL MECHANICS A Symposium in Honor of Raymond D. Mountain April 10-11, 1997, Lecture Room B, Administration Building The purpose of this symposium is two-fold: to bring together experts in statistical mechanics to discuss recent developments, and to celebrate Ray Mountain's sixtieth birthday. Ray has made numerous contributions to statistical mechanics, especially in elucidating the structure and dynamical behavior of liquids, glasses, and clusters as probed by light scattering and molecular-level computer simulations. The Symposium's twelve talks will touch on these and other topics, including inherent structures in liquids; water, ice, and hydrates; light scattering; smoke; friction; earthquake faults; protein folding; Monte Carlo time; and adsorption in zeolites. The speakers will include Michael Klein, University of Pennsylvania, Frank Stillinger, Bell Laboratories, Lucent Technologies, Inc., Paulette Clancy, Cornell University, Peter Cummings, University of Tennessee and Oak Ridge National Laboratory, Jan Sengers, University of Maryland, George Mulholland, NIST, Mark Robbins, Johns Hopkins University, William Klein, Boston University, Robert Zwanzig, National Institutes of Health, Anthony Haymet, University of Sydney, Francis Sullivan, Institute for Defense Analyses Center for Computing Sciences, and Berend Smit, University of Amsterdam. The symposium will start at 8:45 a.m. on Thursday, April 10 and end at 12:30 p.m. on April 11. There will be a dinner in Ray's honor on the evening of April 10. NIST employees who plan to attend are required to register and pay the $75 fee. For additional information contact Richard F. Kayser, 975-2483, e-mail: richard.kayser@nist.gov.

Advance Notice Polymers Division Distinguished Lecturer Series LIQUID-STATE PHASE BEHAVIOR IN POLYOLEFIN BLENDS Professor William W. Graessley Department of Chemical Engineering, Princeton University Thursday, April 10, 1997, 11:00 a.m., Polymers Building, Room B245 Polyolefins are saturated hydrocarbon polymers that are widely used in the form of blends. The components being non-polar, liquid-state phase behavior is governed by net interactions that are purely dispersive in origin, and hence expected to be always repulsive and relatively weak. Until recently, however, very little was known about the structural systematics of interaction strength. Using model polyolefins and neutron scattering, we have now gathered a fairly extensive body of data on such systems, and have also found in the course of the work a fair number of surprises. For example, solubility-parameter formalisms and cohesive energy-internal pressure relationships-schemes that work only qualitatively for monomeric mixtures-become remarkably quantitative for many component pairs. Strong net attractions are found for certain other pairs, and liquid-state phase behavior every bit as complex as that found in monomeric systems for still others. Local packing seemingly dominates the behavior, and the intermolecular part of the pair distribution function, as obtained in recent molecular simulations, appears to be crucial. For additional information call F. Khoury, 975-6753.

Advance Notice Chemical Science and Technology Laboratory INTERNATIONAL HEALTH MONITORING USING BIOLOGICAL AND CHEMICAL MARKERS Dr. Richard D. Thomas International Center for Environment and Health 10:30 a.m., Tuesday, April 15, 1997 Administration Building, Lecture Room A New advances in the understanding of biologic mechanisms are providing increased opportunities to identify and monitor biologic markers of exposure, effect, and susceptibility to chemical exposure. Biologic markers are indicators or signals in a biologic system that a chemical or other agent has had some impact on the system. Markers are measurable chemical, physiologic, or structural alterations within a system. Depending on the magnitude and location of the biological change, the marker may indicate normal physiologic response, potential health impairment, or advancing disease processes. This presentation will focus on the new technologies used in international health monitoring activities. For further information contact Dr. Barbara C. Levin, Chairman, CSTL Colloquium Committee, 975-6682, e-mail: barbara.levin@nist.gov.

Advance Notice THE SEMICONDUCTOR RESEARCH CORPORATION AND ITS RESEARCH PORTFOLIO IN PACKAGING AND INTERCONNECTION Dr. Ron Bracken, Director of the SRC Packaging Sciences Tuesday, April 15, 1997, 1:30 p.m. to 2:30 p.m., Lecture Room D, Administration Building Dr. Ron Bracken, Director of the SRC Packaging Sciences, will present a briefing for NIST staff outlining SRC's mission and their programs in packaging and interconnection sciences. This briefing is intended to acquaint NIST researchers with the SRC program and lay the foundation for further technical linkages between NIST and the SRC.

Advance Notice Physics Laboratory Optical Technology Division, Optical Properties and Infrared Technology Group PROPERTIES OF CRYSTALS WITH TAILOR MADE ISOTOPIC COMPOSITIONS Dr. Manuel Cardona Max-Planck-Institut für Festkörperforschung, Stuttgart, Germany Wednesday, April 23, 1997, 2:00 p.m., Building 221, Room B165 In the past few years, and due in part to the collapse of the Soviet Empire, macroscopic quantities of stable isotopes of many elements have become available at affordable prices. Relatively large single crystals of many materials, including high Tc superconductors and semiconductors, have been grown with tailor made isotopic compositions. They allow the investigation of the dependence of many basic physical properties on average isotopic mass and isotopic disorder. The talk will discuss effects on the lattice constant, phonon spectra, electronic states, thermal conductivity and others for simple diamond and zinc blend-type semiconductors. Possible applications of crystals with tailor made isotopic composition will also be presented.
