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.

Flexible ionic pressure sensors: From migration‐electronic mechanisms to emerging iontronic paradigms

InfoMat, EarlyView.
Mechanisms, materials, structures, and applications of the FIPSs. Abstract Flexible ionic pressure sensors (FIPS) have emerged as promising candidates for bridging the gap between electronics and biologically compatible interfaces. Unlike previous reviews, which focused primarily on materials or devices, this review presents a classification of FIPS ...

Electronegativity‐Driven Frontier Orbital Engineering in B‐Ti Diatomic Synergy Enables Selective Li2C2O4 Conversion in Li‐CO2 Batteries

Rare Metals, EarlyView.
ABSTRACT As a promising alternative to sluggish Li2CO3‐based Li‐CO2 electrochemistry, Li2C2O4 offers a favorable 2e− discharge pathway, yet its selective formation and reversible decomposition remain debated. Herein, we propose a nonmetal‐metal synergistic catalyst—B‐Ti coregulated layered transition metal boride Ti18B18O9/graphene (B‐Ti/TiBOG)—to ...
