Application of direct tomography to a layered C/SiC sample. The left part of the image shows a photograph of the sample, measuring approximately 7 x 10 x 5 mm3. The part studied with X-rays was the indicated subvolume of 7 x 2 x 1 mm3. The result, a detailed 3D map of chemical bonds, is visualised here as a set of isosurfaces within the subvolume, shown on the right, where the different colours represent the different carbon bonds present in the sample.
