Self-assembly of arrays of micro-rings by colloidal evaporative deposition

We describe self-assembly of arrays of micro-rings in a drying process of a mixture of H 2O and C 2H 5OH (1:1) and trace amounts of NH 4OH with suspended SiO 2 nano-particles of 102.5 nm average diameter. A drop of 2 mm diameter of the colloid is placed on a nearly vertical SiO 2 substrate. A drop s...
