| We are conducting research within theoretical surface science.

| It is important to know and understand the detailed atomic structure
  of a surface in order to know the conditions for a chemical reaction
  at a surface.

Here the structure of steps in two directions on rutile TiO2 is
considered.

| See: *Steps on rutile TiO\ :sub:`2`\ (110): Active sites for water and
  methanol dissociation.*

| Chiral transfer from a chiral modifier to a reacting molecule may
  happen if the molecules interact strongly in specific complexes on the
  catalyst surfaces.

We study complex formation by varying the intermolecular positions and
investigate the nature of the chemical bonds within the complexes.

| See: *Direct observation of molecular preorganization for chirality
  transfer on a catalyst surface.*
