The widespread use of molecular machines in biology has long suggested that great
rewards could come from bridging the gap between synthetic molecular systems and the …

The widespread use of controlled molecular‐level motion in key natural processes suggests
that great rewards could come from bridging the gap between the present generation of …

With the long-term goal of producing nanometer-scale machines, we describe here the
unidirectional rotary motion of a synthetic molecular structure fueled by chemical …

An important issue in nanoelectromechanical systems is develo** small electrically driven
motors. We report on an artificial nanofabricated motor in which one short carbon nanotube …

The elasticity and piezoelectricity of zinc oxide (ZnO) crystals and single layers are
investigated from the first-principles calculations. It is found that a ZnO thin film less than …

The maximum power of Feynman's ratchet as a heat engine and the corresponding
efficiency (η∗) are investigated by optimizing both the internal parameter and the external …

In conventional thermodynamics, it is widely acknowledged that the realization of an
isothermal process for a system requires a quasistatic controlling protocol. Here we propose …

Diffusion of a graphene flake on a graphene layer is analyzed and a diffusion mechanism is
proposed for the system under consideration. According to this mechanism, rotational …

We propose a new drive mechanism for carbon nanotube (CNT) motors, based upon the
torque generated by a flux of electrons passing through a chiral nanotube. The structure of …

Abstractt Micro-electro-mechanical and nano-electro-mechanical machines such as
micro/nano pumps use a rotating beam as their energy transmission part. For such devices …
