A new approach to producing metamaterials draws on kirigami techniques to make three-dimensional, reconfigurable building blocks that can be used to create complex, dynamic structures. Because the design approach is modular, these structures are easy to both assemble and disassemble.
Using a previously researched, porous and nanostructured material, containing tungsten trioxide, gold and platinum, researchers tried a new tactic - inverting the design in such a way as to allow the colours to appear much more accurately on the screen.
Researchers have succeeded in binding water-insoluble antibacterial molecules to graphene, and having the molecules release in a controlled, continuous manner from the material.
