Novel chemical design makes hard crystals stretchy

Researchers have designed porous, carbon-based crystals that can stretch to more than twice their length, making them suitable for nanofiltration and pollutant removal. By adding 'soft joints' into the crystal's scaffold, they can be disrupted by specific chemicals, causing the crystal to expand and contract rapidly.
