Organic crystals twist, bend, and heal

Crystals are brittle and inelastic? A novel class of smart, bendable crystalline organic materials has challenged this view. Now, scientists have engineered a molecular soft cocrystalline structure that bends and twists reversibly and without disintegration when stimulated by high temperature, mechanical force, or under UV light. This multifunctional quality makes it a robust candidate for advanced molecular electronics and other new materials.

Hyperexpandable, self-healing macromolecular crystals with integrated polymer networks

Hyperexpandable, self-healing macromolecular crystals with integrated polymer networks, Published online: 02 May 2018; doi:10.1038/s41586-018-0057-7

The integration of macromolecular ferritin protein crystals with hydrogel polymers gives a composite material that expands isotropically and reversibly to twice its size while maintaining periodicity, resists fragmentation and self-heals efficiently.
