Physicists from the University of Utrecht and the Faculty of Physics at the University of Warsaw have observed the Brazil nut effect in a mixture of charged colloidal particles, confirming that the process can occur spontaneously without the need for external energy. The discovery could have applications in fields such as geology and soft matter physics, as well as in industry for the stability of paint and ink.
Physicists have observed the Brazil nut effect in a mixture of charged colloidal particles, confirming that the process can occur spontaneously without external energy. The Brazil nut effect is the phenomenon of large objects rising to the surface of a mixture of small objects, which contradicts the intuition that heavier objects should sink to the bottom due to gravity and inertia force. The discovery could find applications in a wide range of fields, from geology to soft matter physics.
