Australian scientists have created crystals that can be tied in a knot

Flexible Crystals

A group of researchers from Australian Queensland, led by Associate Professor Jack Clegg and Professor John McMurtry, studied the structural mechanism responsible for the elasticity of crystals at the atomic level. This allowed them to create flexible single crystals, which, if desired, can be tied into a knot.

The width of the grown crystals is commensurate with the fishing line, and at a length of 5 cm. They formed as a result of the combination of copper and acetylacetonate, as well as six other structurally related compounds containing copper and other metals with high flexibility.

Experiments of the Queensland team showed that the crystals can repeatedly bend and return to their original state without any traces of deformation. Unusual flexible crystals can be used in many industries. In particular, thanks to them, new hybrid materials for aviation and space technology can appear.

In addition, the bending of crystals changes their optical and magnetic properties, which can be the foundation for new technologies that were previously impossible.
