Many biomolecular motors catalyze the hydrolysis of chemical fuels, such as adenosine triphosphate, and use the energy released to direct motion through information ratchet mechanisms. Here we ...

(Nanowerk News) The ratchet mechanism is a fascinating energy-conversion system that converts disorderly or random motion into orderly, directed movement through a process known as spontaneous ...

A ratcheting wrench, is a type of wrench that employs a ratchet mechanism to block movement in one direction while allowing constant rotation in another. The mechanism, consisting of a pawl and a gear ...

The proposed ratchet mechanism utilizes the asymmetry in surface wettability between the smooth and rough faces of the teeth of a geometrically symmetric gear to achieve ratcheting motion. The ratchet ...
