At 0.6 nanometers thick and half a millimeter wide, the design uses just three atoms of a special material called tungsten disulphide (WS2), whose quantum properties make it particularly suitable ...

The team has created the world’s thinnest lens, measuring just three atoms thick. Contact lenses get pretty thin nowadays, but they’ve got nothing on a new lens from scientists at Stanford and ...

In the search for a suitable replacement, a team from the Swinburne University of Technology has developed a graphene microlens one billionth of a meter thick that ... is the lens or, more ...
