However, one interesting offshoot of "buckyball" research is the development of "buckytubes," which are hollow carbon filaments with cross- sections of atomic dimensions.

The term is specific to the size of the individual particles, which are larger than atomic dimensions but small enough to exhibit Brownian motion.

For example, the bound current usually originates over atomic dimensions, and one may wish to take advantage of a simpler theory intended for larger dimensions.

Good design can be worked out on the mathematical principles of mechanics, but the use of a proper Participation can fine tune it down to virtually atomic dimensions.

A voltaic cell can be thought of as having a "charge pump" of atomic dimensions at each electrode, that is:

In practice R may have a value comparable to atomic dimensions, say about I Ångström unit.

That is why quantum theory did not make itself felt until physics had developed to a stage where minute systems of atomic dimensions could be probed and investigated.

As a result, this mutual uncertainty is of consequence for momenta, distances, energies, and times of the order of atomic dimensions and less.

The high-energy convergent electron beam in STEM provides local information of the sample, even down to atomic dimensions.

Remember that black holes are small in size, but not, I believe as small as atomic dimensions.
