| The structure of ASU-16 - a germanium oxide material of exceptionally low framework density |
My research is mainly concerned the atomic and electronic structure and properties of crystalline inorganic solids. Recent work has particularly focused on the geometry of periodic frameworks and its importance in crystal chemistry. Immediate goals are to design possible topologies, to evaluate which of these would serve as the basis for materials of interesting and useful properties (e.g. gas adsorption and catalytic properties), and to discover routes for their synthetic realization. I, and my group, work closely on these topics with the group lead by Omar Yaghi at the University of Michigan ; we call ourselves the Materials Design and Discovery Group.
Recently a fruitful collaboration with Olaf Delgado-Friedrichs at the University of Tübingen has led to deeper insights into the taxonomy and nature of the nets underlying crystal topology.
I also have a long-standing collaboration with John Spence (ASU Physics) using electron diffraction to get accurate information on electron density in crystals and to interpret this in terms of bonding models.
