Molecular motors have chemical properties that enable unidirectional motion, thus breaking
microscopic reversibility. They are well studied in solution, but much less is known regarding …

Understanding the directed motion of a single molecule on surfaces is not only important in
the well-established field of heterogeneous catalysis but also for the design of artificial …

The central part of any machine is the motor that drives it. The same holds true for machines
on the nanometer scale: in the process of miniaturization, one can go down to the limit of …

Molecular motors convert external energy in a controlled way into useful work, similar to their
macroscopic counterpart. In contrast to biological motors, which operate only in specific …

It is a basic concept of physical chemistry that in thermal equilibrium every individual
process is compensated by its reverse process, which is called microscopic reversibility. It is …

Single molecule machines on a surface can convert external stimuli into motion, allowing the
study on the mechanics of individual small molecules adsorbed on a supporting substrate …
