Left: radiographic image of maltodextrin particles (x = 3.55 mm, c = 0.05 w/w) with the respective transmission scale;

Right: tomographic image of the maltodextrin particle (x = 3.55 mm, c = 0.05 w/w) at a height of 1.55 mm (red line in the left image) with the absorption scale (a.u.); the particle edge is represented by the red dotted line; the green line indicates the actual position of the drying front.

Photo (a) and a fast neutron image (b) of the Li-fueled reactor, post-operation. The flat and dark-field corrected radiographic image reveals a heat exchanger coil, the upper highly oxidized region (dark-gray), and the lower, primarily non-oxidized, elemental Li-rich portion (light gray). The image was taken over four minutes of exposure time. The red line represent roughly the beam size at the detector position.

Figure 7. X-μCT- (A) and n-μCT-based (B) mesiodistal virtual sections through the buccal cusps of the lower molar SMF-8888. The white arrows indicate the positions of two pulp horns barely discernible on the X-ray image (A) but clearly rendered by the neutron-based record (B). The dotted line in (B) highlights the enamel-dentine boundary, not visible in (A).

Figure 4.

(a) The horizontal cut through the tomography image of the partially dried sample (after 11.5 h of drying) reveals the dry zones. The light-gray regions contain water and maltodextrin (it is noted that maltodextrin and heavy water are not distinguished from this image).

(b) Schematic illustration of the different zones that are distinguished from the tomography image. The red arrows depict the expansion direction of the dry zones.

1: accumulation of maltodextrin inside the peripheral maltodextrin belt;

2: peripheral sublimation zone with fractal front;

3: ring of frozen water and maltodextrin;

4: sublimation fingering zone.
