Using the tip of a scanning tunneling microscope, an electric field-induced reversible phase transition between two planar porous structures ("chickenwire" and "flower") of trimesic acid was accomplished at the nonanoic acid/highly oriented pyrolytic graphite interface. The chickenwire structure was exclusively observed for negative sample bias, while for positive sample bias only the more densely packed flower structure was found. We suggest that the slightly negatively charged carboxyl groups of the trimesic acid molecule are the determining factor for this observation: their adsorption behavior varies with the sample bias and is thus responsible for the switching behavior.

This workshop will focus on methods of forging ties between industry practitioners and research communities. Furthermore the workshop focuses on the input that is required from government bodies to stimulate this collaboration. Participants will discuss enabling conditions for collaborative projects, based on the various practical research experiences of the participants.
