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 semiconductor nanocrystals (NCs) are very attractive as optical gain media owing to their ease of fabrication, wide size-dependent colour tunability and spectrally narrow gain profiles 1,2,3 ...

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 ...
