Example of a diffraction experiment on an Ni-Hec clay mineral. The sample is first dried in situ at 150°C under vacuum, and then brought down to a temperature of 50°C and subjected to a pressure cycle of CO2. (a) Contour plot of the evolution of a Bragg reflection as a function of time ([d = 2\pi/q]), pressure and temperature given by the panels to the right. (b) The Bragg reflection curves C1, C2 and C3 given from three marked positions in the contour plot. (c) 2D diffraction pattern of the clay mineral.
