Non-ambient crystallography - is extreme becoming common?

The authors reflect on the publication of various studies regarding non-ambient crystallography in the journal "Acta Crystallographica Section B." Topics discussed include the invention of the main device for high-pressure crystallography in study by C. E. Weir and colleagues, the analysis made by G. J. Piermarini and colleagues on the high-pressure phase of benzene, and the research by P. J. Chupas and colleagues on powder diffraction.
