Example of the results presentation. a Neutron image of the monolith inside the continuous flow tubular reactor: the blue arrows indicate the water flow direction, the red lines indicate the monolith edges and the yellow square indicates the region of interest for images processing. b Color-scaled density map: LL supercritical water is reddish, GL supercritical water is yellowish and liquid water is blueish; the yellow square indicates the region of interest for the vertical density profile. c Water density profile: the three density regions of interest are marked by ρbefore, ρmonolith, and ρafter; the gray zones were not taken into consideration for density calculation, as they are image artifacts induced by the monolith edges and the reactor’s window for neutrons. d Tomographic reconstruction of the monolith region and e Computed histogram showing the volume fraction of densities ρmax and ρmin within the monolith region. Source data for c and e are provided as a Source Data file
