3. Microparticle - Wikipedia

   en.wikipedia.org/wiki/Microparticle

   Particle with dimensions between 1 × 10 −7 and 1 × 10 −4 m. Note 1: The lower limit between micro- and nano-sizing is still a matter of debate. Note 2: To be consistent with the prefix “micro” and the range imposed by the definition, dimensions of microparticles should be expressed in μm. [1]

4. Micronization - Wikipedia

   en.wikipedia.org/wiki/Micronization

   Traditional micronization techniques are based on friction to reduce particle size. Such methods include milling, bashing and grinding.A typical industrial mill is composed of a cylindrical metallic drum that usually contains steel spheres.

5. Microplastics - Wikipedia

   en.wikipedia.org/wiki/Microplastics

   This process of breaking down large plastic material into much smaller pieces is known as fragmentation. [32] It is considered that microplastics might further degrade to be smaller in size, although the smallest microplastic reportedly detected in the oceans in 2017 was 1.6 micrometres (6.3×10 −5 in) in diameter. [34]

   en.wikipedia.org/wiki/Nanomaterials

   A natural, incidental or manufactured material containing particles, in an unbound state or as an aggregate or as an agglomerate and for 50% or more of the particles in the number size distribution, one or more external dimensions is in the size range 1 nm – 100 nm.
