Solvent‐mediated reactivity control of Lewis‐paired dopants enables highly efficient, finely tunable, and stable doping of organic semiconductors. The optimally doped semiconductor films exhibit superior thermoelectric performance and doping stability, feature delocalized polarons along structurally ordered polymer backbones, and outperform ...

An analytical and experimental study of crack extension in center-notched composites [PDF]
The normal stress ratio theory for crack extension in anisotropic materials is studied analytically and experimentally. The theory is applied within a microscopic-level analysis of a single center notch of arbitrary orientation in a unidirectional ...

Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Tough and Rapidly Relaxing Hydrogels Via Programmable Crosslink Kinetics
A kinetic programming strategy encodes supramolecular crosslink lifetimes in single polymer networks via stoichiometric control of fast and slow hostguest interactions. This enables predictable stress relaxation on biologically relevant timescales (0.1‐100 s) while maintaining exceptional toughness (up to 14,500 J m−2), resolving the long‐standing ...
