The specific heat anomaly of ferroelectric Co-I-boracite, Co3B7O13I

Discovery and recovery of delta p-aminobenzoic acid

“…For the pure D2O system we observed poor wetting of the solid during initial attempts at loading the sample. A successful loading was performed where the pABA-d 4 sample was loaded with a pellet of frozen D2O. The D2O melted within the timeframe of loading the press onto the diffractometer which was confirmed through the lack of ice peaks in the diffraction patterns.…”

“…The investigation of solid-state polymorphs using temperature has become routine with the advent of variable temperature devices for analytical equipment such as calorimetry and diffraction. [3][4][5] Whilst significant improvements and developments of both hardware and software have been made, which permit laboratory based characterisation of the effects of pressure, there are still relatively few such studies reported to date. [6][7][8][9][10][11][12][13][14][15][16][17] Phase transformations of organic materials at high pressure can potentially be observed by purely compressing materials into new forms via a single crystal-to-single crystal mechanism, [18][19][20][21][22][23] or through reconstructive mechanisms that result in the degradation of the crystals.…”
