Synopsis: The structure of a particular type of hollow cage higher fullerenes is described and their construction explained from a symmetry breaking mechanism starting from perfect icosahedral symmetry of to specific subgroups . This mechanism expands and completes previous results describing the existence of other groups of fullerenes ) based on the breaking of icosahedral symmetry of to the subgroups and . The mechanism is extended to describe the cases that generate carbon nanotubes.
Synopsis: Combined atomic and magnetic pair distribution function refinements have been performed against neutron scattering data from MnO, recovering the expected long-range-ordered antiferromagnetic state and supporting a scenario of monoclinic symmetry on a local length scale of 100 Å. This represents the first experimental application of the magnetic PDF method.
