Production of carbonate and silica nano-particles in

Oct 01, 2006The “grinding limit” for the processes in the mills has been discussed. The nanoparticle sizes of the ground products obtained in the mills were determined by a scanning mobility particle sizer (SMPS), an acoustic particle sizer (APS-100), a nitrogen gas adsorption method (BET), and transmission electron microscopy (TEM).

Nanoparticles an overview ScienceDirect Topics

Nanoparticles are vesicular-like vehicles with a diameter of less than 1 μm. Their properties include systemic stability, target site specificity, and level of solubility. These properties are mainly affected by the molecular structure of the vehicle surface along with the size and shape of the particle, which can all be modified through customized synthetic chemistry [1,2], providing a

Nanoparticle Wikipedia

A nanoparticle or ultrafine particle is usually defined as a particle of matter that is between 1 and 100 nanometres (nm) in diameter. The term is sometimes used for larger particles, up to 500 nm, [citation needed] or fibers and tubes that are less than 100 nm in only two directions. At the lowest range, metal particles smaller than 1 nm are usually called atom clusters instead.
