Figure 4
The upper left panel shows the visible fluorescence from the focused X-ray micro-beam as it traverses through the sample recess of the diamond anvil in the hydrothermal diamond anvil cell (HDAC). The remaining panels show a sequence of images captured from a video recording of the WO3 + H2O sample in the HDAC at 873 K. The upper right panel shows the sample at 11:15:16 before exposure to the X-ray beam. With the X-ray beam turned on, a dark colloidal precipitate streak is clearly visible at the bottom of the recess at 11:15:36 in the lower left panel. The lower right panel shows that the previously formed precipitate has dissolved into the supercritical fluid, after the X-ray beam is turned off.
