Stephan Hruszkewycz Tuesday, September 25 • 4 Pm • Tech L211
THE MATERIALS SCIENCE AND ENGINEERING DEPARTMENT COLLOQUIUM SERIES PRESENTS: Stephan Hruszkewycz Assistant Physicist, Argonne National Laboratory Opportunities for materials science with coherent x-ray diffraction imaging Recent progress in 3D coherent x-ray diffraction imaging methods can enable high resolution structural imaging of nano-structured crystalline materials under operating conditions. In this talk, I discuss developments in Bragg coherent diffraction imaging (BCDI) that aim to broaden the envelope of materials science problems that can be addressed with the technique. Following an introduction of the basic principles of the method, two specific topics will be discussed: 1) BCDI at high x-ray energies that provide dramatic penetrating ability, 2) Bragg ptychography that enable imaging of targeted sub- volumes of a crystal. Both approaches will be discussed in the context of materials science problems that can be addressed in-situ at next-generation synchrotron storage rings including the Upgraded Advanced Photon Source project now underway at Argonne National Laboratory. Stephan Hruszkewycz is a staff scientist in the Materials Science Division at Argonne National Laboratory. His research focuses on developing and using coherent x-ray scattering techniques to interrogate nanoscale materials structure and dynamics under working conditions to reveal structure-property relationships. Currently he is using strain- sensitive coherent Bragg diffraction to image subtle strain fields in nanoscale crystals for photonic and quantum information applications. These research thrusts are pursued at high-brightness synchrotron sources with state-of-the-art coherence-preserving beamlines, including those at the Advanced Photon Source, NSLS-II, and LCLS, and aim to broaden the applicability of coherent diffraction imaging within both the broader materials science community. -
MEMOIRS Row Standing on the Stern, Venetian Style, from the Lido, Where I Lived, to the School in Venice, Where I Studied
BRUNO BENEDETTO ROSSI April 13, 1905–November 21, 1993 BY GEORGE W. CLARK The initial motivation of the experiment which led to this discovery [of Sco X-1] was a subconscious feeling for the inexhaustible wealth of nature, a wealth that goes far beyond the imagination of man. That feeling was possi- bly generated by experiences in my previous work on cosmic rays; more likely it was inborn and was the reason why, as a young man, I went into the field of cosmic rays. In any case, whenever technical progress opened a new window into the surrounding world, I felt the urge to look through this window, hoping to see something unexpected.1 BEGINNINGS RUNO ROSSI WAS BORN April 13, 1905, in Venice, the el- Bdest of three sons of Rino Rossi and Lina Minerbi. His father was an electrical engineer whose successful career began with work on the electrification of Venice. He wrote in his autobiography2 that his father loved science and would have chosen it for a career except for practical consider- ations. He attributes to his father the influence that turned what may have been an “inborn tendency toward science . into a lifelong commitment.” He recalled: perfectly clear winter mornings when the air was so unusually transparent that the Alps surrounding Venice became clearly visible and appeared in- credibly close (Fata Morgana if you are a child or a poet, anomalous atmo- spheric refraction if you are a scientist). On those mornings I would try to find a sandalo (a small gondola) and, accompanied by a friend, I would 3 4 BIOGRAPHICAL MEMOIRS row standing on the stern, Venetian style, from the Lido, where I lived, to the school in Venice, where I studied. -

Biographical Memoirs, VOLUME 85 PUBLISHED 2004 BY THE NATIONAL ACADEMIES PRESS WASHINGTON, D.C. Photo by Anthony di Gesu, La Jolla, California WILLIAM DAVID MC ELROY January 22, 1917–February 17, 1999 BY J. WOODLAND HASTINGS ILLIAM DAVID MCELROY, a biologist who made ground- Wbreaking discoveries in bioluminescence and was an administrator of great talent, died of respiratory failure at Scripps Memorial Hospital in San Diego, California, at the age of 82. He was an innovative and internationally promi- nent scientist and administrator, with a continuing agenda for experimental projects and research support for all areas of science, both basic and applied. At the time of his death McElroy was a professor emeritus at the University of California, San Diego, having served as its chancellor from 1972 to 1980. He was on the faculty at the Johns Hopkins University, where from 1946 until 1969 he was the founding director of the McCollum-Pratt Institute, and from 1956 to 1969 the chairman of the biology depart- ment. He was a member of many professional scientific societies and served as president of several, including three of the largest: the American Society of Biological Chemists, the American Institute of Biological Sciences, and the 116,000- member American Association for the Advancement of Science. He served on the President’s Science Advisory Committee under both Kennedy and Johnson (1962-1966), was elected to the National Academy of Sciences in 1963, was director of the National Science Foundation under Nixon 3 4 BIOGRAPHICAL MEMOIRS (1969-1972), and was a member of the President’s Committee on the National Medal of Science Award (1972). -

October 2006 Issue 132 AAS NEWSLETTER A Publication for the members of the American Astronomical Society PRESIDENT’S COLUMN J. Craig Wheeler, [email protected] August is a time astronomers devote to travel, meetings, and writing papers. This year, our routine is set 4-5 against the background of sad and frustrating wars and new terror alerts that have rendered our shampoo Calgary Meeting suspect. I hope that by the time this is published there is a return to what passes for normalcy and some Highlights glimmer of reason for optimism. In this summer season, the business of the Society, while rarely urgent, moves on. The new administration 6 under Executive Officer Kevin Marvel has smoothly taken over operations in the Washington office. The AAS Final transition to a new Editor-in-Chief of the Astrophysical Journal, Ethan Vishniac, has proceeded well, with Election some expectation that the full handover will begin earlier than previously planned. Slate The Society, under the aegis of the Executive Committee, has endorsed the efforts of Senators Mikulksi and Hutchison to secure $1B in emergency funding for NASA to make up for some of the costs of shuttle 6 return to flight and losses associated with hurricane Katrina. It remains to be seen whether this action 2007 AAS will survive the budget process. The Executive Committee has also endorsed a letter from the American Renewals Institute of Physics supporting educators in Ohio who are fending off an effort there to include intelligent design in the curriculum. 13 Interestingly, the primary in Connecticut was of relevance to the Society. -

In this document, we describe how detailed studies of stellar dynamics deep in the potential well of a galaxy offer several exciting directions in the coming decade. First, it will be possible to obtain precision measurements of the Galaxy’s central potential, providing both a unique test of General Relativity (GR) and a detection of the extended dark matter distribution that is predicted to exist around the SMBH. Tests of gravity have not previously been pos- sible on scales larger than our solar system, or in regimes where the gravitational energy of a body is >∼1% of its rest mass energy. -
