Elastic instabilities in mechanical metamaterials can be harnessed to programme fracture behaviour, transforming instability from a failure mechanism into a design principle that increases fracture energy by up to tenfold.

Based on the machine learning-selected solvent, we successfully suppressed the fast crystallization of antisolvent-free perovskites fabricated at high ambient temperature and widened the temperature processing window.
