German scientists have made the world’s smallest gears

دانشمندان آلمانی کوچکترین چرخ‌دنده‌های دنیا را ساختند

In many branches of the technology world, being smaller means being better, and now the dimensions of some devices have become so small that they can be measured on an atomic scale. Now, in the continuation of this miniaturization fever of university researchers Erlangen Nuremberg Germany claims to have built the world’s smallest functional gear.

Obviously, molecular machines and nanobots will be of particular importance in the coming decades because of their applications in electronic components, drug delivery, and the manipulation of a cell or molecule, and the results of experiments by German researchers will be applied in these areas.

It is worth mentioning that the gear made by these researchers consists of two interlocking parts, which include: Trypticin molecule It has a butterfly-like structure that is perpendicular to the flat part Tivindigo molecule With the same function as a page, it is placed.

Performance and application of the world’s smallest gears

According to Article Released, these two molecules or parts move like a gear and have a transfer coefficient 2: 3 are. Thus when the page 180 Rotate the degree, butterfly only 120 The degree rotates.

Also the whole device consists of 71 Atom And equal length 1.6 nm Is; The size, according to the scientists who made it, is the smallest operating gear in the world.

It should be noted that this system can be easily turned on or off with light, and this has led to the name “Optical gear” Or Photogear Be selected for it. It’s also good to know that this is the first time that molecular gears have been directly controlled in this way, instead of inactive and stationary motion.

researchers they say With this new optical molecular gear, molecular devices can be made more flexible. This technology could pave the way for the construction of nano-dimensional gear systems, systems that, like their larger prototypes, can transmit motion over longer distances, in different directions, and at different speeds.
