Engineers have built a bright - light emitting device that is fully transparent when turned off. The light emitting material in this device is a monolayer semiconductor, which is just three atoms thick.
(PhysOrg.com) -- Any fan of Star Trek knows about the joys of the holodeck. The idea of a 3D, 360-degree immersive digital environment, projected on demand, is an enticing one that has thus far been confined to the silver screen, but technologies are emerging that just may make this possible. In 2008 Physorg reported on a 3D fog display on a room-sized scale, but it could not give a 360 degree experience. New developments in this area may make this possible at some point in the future.
