The 5th Frolic Goats High-Pressure Diffraction Workshop, held at the Adam Mickiewicz U. in Poznań, April 15-17, 2012, was attended by 36 crystallographers representing 5 countries. After an introduction to high-pressure techniques by A. Katrusiak, the lecturers spoke about methods of correcting high-pressure data measured for samples in a diamond-anvil cell (DAC) by X-ray diffraction (M. Kaźmierczak); high-pressure powder-diffraction crystallography (A. Budzianowski); high-pressure experiments at synchrotrons Michał Dobrowolski (ESRF); computation of interaction energy in molecular crystals (K. Dziubek and J. Marciniak); and graphical presentations of high-pressure structures (A. Katrusiak). Another session was dedicated to high-pressure results: transformed interactions in high-pressure (+)-sucrose polymorph (E. Patyk); the hidden polar phase of imidazole (D. Paliwoda); Carney's rule in chloroethanes (M. Podsiadło); remote switching of amine hydrophilicity (M. Andrzejewski); pressure-induced hydration in thiourea (A. Olejniczak); and a new high-pressure polymorph of KH₂PO₄, KDP (Weizhao Cai). The Workshop included hands-on laboratory exercises on DAC operation, alignment and loading, and diffraction experiments. A Frolic-Goats Spring Project has been announced, for encouraging the participants to start high-pressure experiments in their laboratories. The round-table discussion in the closing session was aimed at promoting the use of pressure in scientific investigations and collaboration involving high-pressure facilities.

The kayak excursion down the Warta River.

The workshop was sponsored by the Faculty of Chemistry, Agilent Technologies and Bruker Poland, and was organized under the auspices of the Polish Foundation of Science. The participants experienced extreme conditions during the kayak excursion down the Warta River from the Wielkopolski National Park to the historical centre of Poznań, 17 km down the Warta River, where strong winds and waves pushed kayaks upstream; otherwise it was warm and sunny in Poznań during the Workshop.
