Dual‐Mode Magnetic Elastomer for On‐Demand Motion and Degradation

Advanced Functional Materials, EarlyView.
A dual‐mode magnetic elastomer is introduced, enabling DC field‐driven programmable actuation and AC field‐driven magnetothermal degradation. GHz‐range magnetic fields generate ultrafast heating of magnetic nanoparticles that activates cleavage of the silicone elastomer matrix.

Self‐Adaptive Anhydrous Passivation Mitigates Open‐Circuit Voltage Loss in Pb‐Sn Mixed Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
In this report, a self‐adaptive anhydrous passivation strategy is introduced by incorporating trimellitic anhydride (TMAH) into the perovskite precursor. In situ hydrolysis of TMAH yields trimellitic acid (TMA); ‐C═O/‐COO− groups of TMAH/TMA form a chelate with undercoordinated Pb2+/Sn2+, regulate nucleation, promote (100) orientation, passivate ...
