Synopsis: Ternary intermetallics - 13 026 compounds contained in the database Pearson's Crystal Data - are discussed with respect to their components, structure types and stoichiometries.
Synopsis: The structure of a particular type of hollow-cage higher fullerene (C60+N24) is described and their construction explained from a symmetry-breaking mechanism starting from perfect icosahedral symmetry of C60 to specific subgroups A1 × A1. This mechanism expands and completes previous results describing the existence of other groups of fullerenes (C60+N10, C60+N18) based on the breaking of icosahedral symmetry of C60 to the subgroups H2 and A2. The mechanism is extended to describe the cases that generate carbon nanotubes.
Synopsis: A method from numerical algebraic geometry, called homotopy continuation, is used to determine small crystal structures of four or fewer atoms directly from a minimum set of diffraction intensities.
Synopsis: Combined atomic and magnetic pair distribution function (PDF) 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.
