This volume is the status report of the international community of practitioners
of x-ray microscopy. It contains the reviews and work presented at the 6th
International Conference on X-Ray Microscopy held in Berkeley, 2-6 August 1999.
The techniques are being applied to biological imaging where, for example,
special labeling can reveal the location of specific proteins in cells, while
cryogenic sample handling prevents x-ray damage to cells. These techniques can
also be used to analyze objects on a 10 nm size scale, allowing the study of
their physical and chemical state. For example, chemical processes in the
environment can be examined on the surfaces of microscopic particulate
