A colloidal solution is a uniform dispersion of two completely different types of components—particles or droplets of one phase, called the solute, in a second, typically liquid, phase, called the ...

Colloidal particles undergo perpetual Brownian motion resulting from the stochastic and rapid collisions with solvent molecules. As a result, an ensemble of colloidal particles spreads diffusively to ...

Brownian diffusion is a ubiquitous mechanism of transport for ions, molecules and submicrometre particles. It can limit the rate of chemical reactions as well as determine the efficiency of ...
