Nanofibers on the rise! The cover picture shows that individual carbon nanofibers can by grown from a mixture of amorphous carbon and Ce0.8Gd0.2O1.9/Ni nanoparticles by using an electron beam in a 300 kV transmission electron microscope, without any gaseous carbon source, and external heating. In their Communication on p. 2591 ff., W. Zhang and L. T. Kuhn demonstrate that an electron beam can bridge physical mixing to chemical bonding in a designed porosity. The induced strong metal-support interaction effect can result in a local arrangement of carbon atoms in the amorphous carbon.
