Opals, as hydrated forms of silica, encompass a wide range of materials formed by both biogenic and diagenetic processes. The genesis of opal involves precipitation from silica‐rich fluids and ...

Scientists have discovered a completely new type of opal formed by a common seaweed which harnesses natural technology by self-assembling a nanostructure of oil droplets to control how light reflects ...
