Force‐Induced Selective Carbon‐Carbon Bond Cleavage in Mechanoresponsive Topochemical Polymers

Advanced Materials, EarlyView.
A new class of mechanoresponsive polymers based on polybiidenedionediyl (PBIT) derivatives exhibits distinct color changes upon mechanical stimuli such as grinding, milling, and compression. The response arises from depolymerization and backbone conjugation changes.

Autonomous Implants

Advanced Materials, EarlyView.
An ideal implant should mimic native tissues such that it can integrate, sense, heal, and continue to function, i.e., be autonomous. Although early, there are good steps taken in this way, e.g., the development of stimuli‐responsive, self‐powering, self‐actuating, self‐healing, self‐regenerating, and self‐aware implants.

Resolving the Structural Duality of Graphene Grain Boundaries

Advanced Materials, EarlyView.
Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.
