Engineers created carbon nanostructure stronger than diamond

Engineers created a carbon nanostructure stronger than diamond in relation to density. This is stated in the work of researchers from the University of California, published in the journal Nature Communications.

During the study, scientists managed to create a structure consisting of closely connected closed cells instead of cylindrical trusses, which most often arise when trying to design carbon blocks.

This was achieved with the help of a complexly organized process of laser 3D printing, two-photon lithography with direct laser recording. During this process, scientists added a photosensitive resin to carbon, which solidified upon contact with two photons.

According to the researchers, this technique allows reproducing cells whose face thickness is only 160 nanometers.

The new structure design improved its average density to 639% compared to a conventional carbon structure, and the strength to stiffness ratio to 552%.

The study will expand the use of materials that are often found in nature due to the maximum use of their properties, the study says.
