Some DNA molecules may serve as handy micromachines to convert rotational motion into linear translation, an important function for positioning minuscule parts in microscopic devices. Researchers at ...

Rotary motor motion is usually converted to linear through rack and pinion sets, belts and pulleys, and other mechanical linkages. These are effective but limited systems. In contrast, integrated ...

A wide variety of industries operate factories with large-format manufacturing lines, creating a need for long-travel motion axes and transfer robots. Some of these gantry and Cartesian robots can ...

Construction of nano-devices that can generate controllable unidirectional rotation is an important part of nanotechnology. Here, we design a nano-turbine composed of carbon nanotube and graphene ...
