The smallest lattice in the world is visible under the microscope only. Struts and braces are 0.2 µm in diameter. Total size of the lattice is about 10 µm. Credit: J. Bauer / KIT
Scientists have now presented the smallest human-made lattice structure. 3D lattice with glassy carbon struts and braces of <200 nm in diameter has higher specific strength than most solids. They are smaller than comparable metamaterials by a factor of five. Apps may include electrodes, filters or optical components.
“Lightweight construction materials, such as bones and wood, are found everywhere in nature,” said Dr.-Ing. Jens Bauer of Karlsruhe Institute of Technology (KIT)...
