Particle size is a notion introduced for comparing dimensions of solid particles , liquid particles , or gaseous particles . The notion of particle size applies to particles in colloids , in ecology , in granular material (whether airborne or not), and to particles that form a granular material (see also grain size ).
The term colloidal suspension refers unambiguously to the overall mixture (although a narrower sense of the word suspension is distinguished from colloids by larger particle size). A colloid has a dispersed phase (the suspended particles) and a continuous phase (the medium of suspension).
Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials . This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.
A sol is a colloidal suspension made out of tiny solid particles [1] in a continuous liquid medium. Sols are stable, so that they do not settle down when left undisturbed, and exhibit the Tyndall effect, which is the scattering of light by the particles in the colloid. The size of the particles can vary from 1 nm - 100 nm.
A colloidal crystal is an ordered array of colloidal particles and fine grained materials analogous to a standard crystal whose repeating subunits are atoms or molecules. [1] A natural example of this phenomenon can be found in the gem opal , where spheres of silica assume a close-packed locally periodic structure under moderate compression .
Colloidal System: Finely divided particles of any substance with diameter lying within 1-100 nm range dispersed in any medium constitute what is termed a "colloidal system solution". It is a two phase system.
Particle size analysis, particle size measurement, or simply particle sizing, is the collective name of the technical procedures, or laboratory techniques which determines the size range, and/or the average, or mean size of the particles in a powder or liquid sample.
The set of parameters for the simulation of the solvent are: solvent particle mass ; average number of solvent particles per collision box ; lateral collision box size ; stochastic rotation angle ; kT (energy) time step
