X-ray absorption by nanometer sized soot particles in an ethylene flame has been studied using a beam from the ESRF synchrotron. This absorption appears to lead to the destruction of the particles. Application of this phenomenon to the release of molecules from the surface of interstellar dust grains is discussed.
