Ice segregation
Videos
Ice segregation is the geological phenomenon produced by the formation of ice lenses, which induce erosion when moisture, diffused within soil or rock, accumulates in a localized zone. The ice initial

Ostwald ripening

Ostwald ripening is a phenomenon observed in solid solutions and liquid sols that involves the change of an inhomogeneous structure over time, in that small crystals or sol particles first dissolve an
Ostwald ripening in palladium nanoparticles dissolved in formaldehyde at 6 (a), 24 (b), 48 (c) and 72 hours (d). The small palladium particles are being consumed as the larger ones grow bigger.
