The poster session at the Users' Meeting attracted nearly 50 entries. Topics presented ran the gamut from macromolecular structures to software for processing X-ray fluorescence data to GISAXS analysis of block copolymer structures. A team of 5 judges evaluated the posters and, after considerable discussion and some tough decision-making, awarded two $100 prizes:
The Best Scientific Achievement prize went to “Jahn and Teller Play with Nano-Chessboards at CHESS”, by S.M. O'Malley, P.L. Bonanno, K.H. Ahn, A.A. Sirenko, A. Kazimirov, S. Park, and S.-W. Cheong; the Sirenko group hails from New Jersey Institute of Technology. The poster explained how a ZnMnGaO4 film consisting of a checkerboard of nanorods of two different spinel phases could be self-assembled, analyzed, and understood in terms of the packing between matching surfaces of the different domains. This is not an area of expertise of any of the judges, but one of the poster's authors was on hand to clearly explain it to passersby. The award was presented by a representative from Brush-Wellman, which kindly sponsored the prize.
For Best Technical Achievement, the winning poster was “3D Program for Modeling the Capillary Far-field Pattern”, by H.-S. Lee, T. Szebenyi, S. Cornaby, and D. Bilderback, of CHESS. It described a Matlab program for simulating the image of the X-ray source produced in the far field by a focusing capillary, using the shape parameters from a real capillary; this will be a useful addition to the resources of the capillary development project headed by Bilderback. The program will aid in evaluating the quality of existing capillaries, as well assisting in the design of new ones. The award was handed out by a representative of the sponsor, Minarik Corporation.
