• Electron diffusion, producing electric current
• Thermal diffusion, in the form of Heat flow
• Knudsen diffusion of particles from very small containers
• Momentum diffusion
• Osmosis
• Photon diffusion, an optical effect
  • Diffuse reflection, the reflection of light from an uneven or granular surface
• Reverse diffusion
