Science Highlights

1. Professor Janos Hajdu, Uppsala University, Sweden. Professor Hajdu presented the

Scientific Highlight at the 2000 NSLS Users’ Meeting, “Femtosecond Imaging of

Biomoleculars with X-Ray s.”

2. Elaine DiMasi of the BNL Physics Department aligns a sample chamber at Beamline

X22A for x-ray scattering from clays to study changes in structure during a hydration process

that is controlled by temperature and water vapor pressure.

3. Jianzhong Zhang of SUNY at Stony Brook and Heather Goss of Haverford College

examine a high-pressure sample prior to X-ray diffraction at Beamline X17B 1.

4. Giovanni Gigante, Health & Medical Physics, University of Rome, performing energy

dispersive x-ray fluorescence analyses of paper samples treated for deacidification at Beamline

X26A in collaboration with BNL’s Department of Advanced Technology. Dr. Gigante was

also the 7000th user to perform research at the NSLS.

5. Mark Chance, Albert Einstein College of Medicine, during the 2000 NSLS Users’

Meeting. Mark is also a member of the NSLS Users’ Executive Committee and has served as

its Chair for the 2000-2001 year.

6. Robert Sweet, of the BNL Biology Department, is part of an international collaboration

that used freeze-trapping and protein crystallography to discover transition states in catalysis

by a molecule that is “the biological equivalent of a blow-torch.”

7. Michael Vaughan of SUNY at Stony Brook and Jeremy Smith of Earlhan College

examine large volume high-pressure apparatus at Beamline X17B 1.
