Ben Bartlett created an array of hexagonal mirrors that can reflect the sun's rays in any pattern and can be created by 3D printing. This 3D-printable hexagonal mirror array was created to apply for ...

Barredo and team report their use of precision optical-engineering methods to sort atoms into arbitrary 3D patterns. Barredo et al. extend their previously reported method for 2D atom sorting to three ...

Most DNA research on controlled self-assembly deals with two-dimensional, i.e. flat, patterns and an expansion of these arrays into the third dimension has been challenging. New research coming out of ...
