Cover Picture: Imaging Nanocarbon Materials: Soot Particles in Flames are Not Structurally Homogeneous (ChemPhysChem 14/2013)



original image

The cover picture shows nascent soot particles extracted from inside a flame and probed for the first time by helium-ion microscopy. When reliably characterized, nascent soot particles smaller than 15 nm reveal structural features that remained uncovered in earlier studies by transmission electron microscopy. The results suggest that nascent soot is structurally and chemically inhomogeneous. Even the smallest particles deviate from a spherical shape, as described on p. 3248 by H. Wang, K. Kohse-Höinghaus et al.
