Carbon Nanostructure Stronger than Diamond By Strength to Density | NextBigFuture.com

Researchers have architecturally designed plate-nanolattices – nanometer-sized carbon structures – that are stronger than diamonds as a ratio of strength to density. The team’s design has been shown to improve on the average performance of cylindrical beam-based architectures by up to 639 percent in strength and 522 percent in rigidity. They designed and fabricating the material, which consists of closely connected, closed-cell plates instead of the cylindrical trusses common in such structures over the past few decades. They used complex 3D laser printing process called two-photon polymerization direct laser writing. The laser is focused inside a droplet of an ultraviolet-light-sensitive
