Due to their small size, quantum mechanics plays an important role in some nanomotors. For example, in 2020 Stolz et al. showed the cross-over from classical motion to quantum tunneling in a nanomotor made of a rotating molecule driven by the STM's current. [47] Cold-atom-based ac-driven quantum motors have been explored by several authors. [48 ...
Nanometre-scale plasmonic motor. Illustration of the nano-sized gold motor, sandwiched between two identical 300 nm-thick square-shaped silica microdisks with an area of 2.2×2.2 mm.

The Nano-particle field extraction thruster or NanoFET is an experimental high-speed spacecraft engine under development by the University of Michigan. [1] It provides thrust by emitting charged particles. These particles are cylindrical carbon nanotubes which can either be contained in tanks or manufactured in-flight.
As figure 3.1 shows, the nanomotor consists of a double-walled CNT (DWNT) formed from an achiral (18,0) outer tube clamped to external gold electrodes and a narrower chiral (6,4) inner tube. The central portion of the outer tube is removed using the electrical-breakdown technique to expose the free-to-rotate, inner tube. The nanodrill also ...
Some proponents of nano-robotics, in reaction to the grey goo scenarios that they earlier helped to propagate, hold the view that nano-robots able to replicate outside of a restricted factory environment do not form a necessary part of a purported productive nanotechnology, and that the process of self-replication, were it ever to be developed ...
The Nano electrokinetic thruster is a theoretical space propulsion system based on the principle of electro-osmosis (also electroosmotic flow). It allows for a high specific impulse and high thrust -to-power ratio as well as a high final velocity which makes it suitable for a wide variety of applications.
Scientists teach rats to drive tiny cars and ‘unexpectedly’ discover the rodents enjoy revving their engines Caitlin McCormack November 17, 2024 at 11:12 PM
The term was coined by John Storrs Hall in 1989. [5] Hall thought of it as a nanotechnological replacement for car seatbelts.The robots would be microscopic, with extending arms reaching in several different directions, and could perform three-dimensional lattice reconfiguration.
