The gear, developed by chemists at the Friedrich Alexander University, is only 1.6 nm in size. Reducer
Scientists say that when the "plate" is rotated 180°, the "propeller" rotates 120°. Thus, the gear ratio of the nanoreducer is 2:3.

"Plate" and trypticene "propeller" are giveninto action with light. Under the influence of a light source, the gear components move in locked synchronous rotation. At the same time, as the researchers found, under the influence of heat, only the “propeller” begins to rotate, while the “plate” remains stationary and the gear wheel slips.
The researchers note that molecular analogsgears existed before, but so far no one has been able to control them. The authors of the development note that the gear wheel allows you to change the direction and speed of movements and connect the elements of the machine with each other. This component will help in the creation of a molecular machine that chemists in different countries are working on.
Earlier, Hi-Tech said that American biochemists created a rotor and an axis for a molecular engine from proteins.
