There are two methods in nanotechnology: "top down" and "bottom up." The nanotechnology that T.K. is pursuing is top down meaning large particles are made smaller and smaller or the "nanoization" of particles. This creates a tremendous amount of energy on the particles. This strong energy has a tendency to cause gouges and breaks in the surface of the particles. The end result is unstable, readily leading to negatives impacts of recoagulation and changes in particle's physical properties.
Therefore, the ideal solution is to find out how to mix at submicron levels without imparting damage to the particle. The T.K. Filmix does not impart damaging energy and it has the special feature of being able to disperse gradually those areas that are the source of coagulation (Part 4), but it is very difficult to pulverize primary particles and crystals. However, if Filmix is used for particles that have a tendency toward inconsistent fragmentation or become unstable from reaction in the mixing process, we discovered that we can achieve roundness in the particles plus even distribution and consistency. This represents a major change in the approach of nanotechnology using the bottom up method to process particles.
The photos below show metal particles before and after processing.

In nanotechnology, there is more than just achieving submicron mixing. The surface and shape of the particles must also be controlled. Why don't you give Filmix a try the next time your R&D efforts do not product desired mixing results.
