Even hard-sphere colloidal suspensions display Fickian yet non-Gaussian diffusion
We scrutinize three decades of probability density displacement distribution in a simple
colloidal suspension with hard-sphere interactions. In this index-matched and density …

Exceptionally slow movement of gold nanoparticles at a solid/liquid interface investigated by scanning transmission electron microscopy
A Verch, M Pfaff, N de Jonge - Langmuir, 2015 - ACS Publications
Gold nanoparticles were observed to move at a liquid/solid interface 3 orders of magnitude
slower than expected for the movement in a bulk liquid by Brownian motion. The nanoscale …
