The easily rotatable peripheral aromatic rings around central benzene in hexaarylbenzene
(HAB) derivatives create a very intriguing nonplanar, propeller-shaped geometry. Because …

The drive to miniaturize devices has led to a variety of molecular machines inspired by
macroscopic counterparts such as molecular motors, switches, shuttles, turnstiles, barrows …

Although the local environment of a molecule can play an important role in its chemistry,
rarely has it been examined experimentally at the level of individual molecules. Here we …

The design of a single-molecule machine consisting of functional components requires a
detailed understanding of its mechanical motion,. The scanning tunnelling microscope …

This article reviews manipulation of single molecules by scanning tunnelling microscopes, in
particular vertical manipulation, lateral manipulation, and inelastic electron tunnelling (IET) …

Gears are microfabricated down to diameters of a few micrometres. Natural macromolecular
motors, of tens of nanometres in diameter, also show gear effects. At a smaller scale, the …

In this paper, dynamic behavior of double layered nanoplate systems (DLNPS) with respect
to a moving nanoparticle is investigated. Both layers of DLNPS are assumed to be …

Dynamic analysis of nanotube structures under excitation of a moving nanoparticle is carried
out using nonlocal continuum theory of Eringen. To this end, the nanotube structure is …

Two molecule-gears, 1.2 nm in diameter with six teeth, are mounted each on a single copper
adatom separated exactly by 1.9 nm on a lead surface using a low-temperature scanning …

Atomic manipulation using a scanning tunneling microscope (STM) tip enables the
construction of quantum structures on an atom-by-atom basis, as well as the investigation of …
