DESCRIPTION:*Nick Funnell\, ISIS Neutron and Muon Source*\n_PEARL – high
  pressure and neutrons_\n\n PEARL is the dedicated high-pressure powder di
 ffractometer at the ISIS neutron and muon facility\, designed around the l
 arge-volume Paris-Edinburgh press which is capable of applying multi-gigap
 ascal pressures\, whilst simultaneously exploring a wide temperature range
 . The use of pressure is an unrivalled thermodynamic tool for exploring th
 e phase behaviour of materials\; it provides the ability to access new\, o
 therwise unobtainable\, phases\; tune material functionality\; and push cr
 ystal structures to the limit of their stability.\n\nThis talk will presen
 t the current capabilities available on the PEARL instrument as well as on
 going developments for planned future use in the user programme. Lastly\, 
 some select examples of recent work on the instrument will be given.\n\n*K
 atharina Märker\, Dept. of Chemistry\, University of Cambridge*\n_Structu
 re determination of organic nanotubes by DNP-enhanced solid-state NMR spec
 troscopy_\n\nMagic-angle spinning solid-state NMR is a powerful technique 
 for structural studies\, but often faces limitations due to its intrinsica
 lly low sensitivity. Recent ground-breaking developments in the field of d
 ynamic nuclear polarization (DNP) have enabled sensitivity enhancements of
  solid-state NMR experiments by several orders of magnitude\, opening up e
 xciting new possibilities for this field.\nThe power of DNP-enhanced solid
 -state NMR for structure determination of organic solids at their natural 
 isotopic abundance will be demonstrated in this talk. The increased sensit
 ivity enables carbon-carbon and carbon-nitrogen interatomic distance measu
 rements without the need of 13C and/or 15N isotopic enrichment. It will be
  shown that such dipolar recoupling based experiments provide invaluable i
 nformation for structure determination\, some of which would be nearly imp
 ossible to obtain with isotopically labeled samples.
