Foams are multiscale materials that have an enormous number of uses. As the relevant
structural length-scales span from a few nanometres up to millimetres a number of …

Diffusing wave spectroscopy (DWS), which makes use of multiple scattered light in
concentrated and highly turbid colloidal systems, has emerged as a very reliable and …

Foams are dispersions of gas bubbles in water, stabilized by surfactants. Foams evolve with
time due to three different processes: liquid drainage produced by gravity, bubble growth …
