Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials

Advanced Science, EarlyView.
ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...

Solder‐free room‐temperature multichannel integration for soft hybrid electronics

InfoMat, EarlyView.
A room‐temperature direct interconnection (RTDI) technique enables solder‐free, stretchable bonding of multichannel soft–rigid interfaces via hydrogen bonding and molecular entanglement. It achieves 24.7× stronger mechanical bonding than conventional methods and maintains resistance variation within one order of magnitude at 110% strain.
